Samuel Harris Altman (born April 22, 1985) is an American entrepreneur and investor known for co-founding OpenAI and leading Y Combinator. He served as Y Combinator’s president from 2014 to 2019 and became OpenAI’s chief executive officer in 2019. His earlier career included co-founding Loopt, a location-sharing startup acquired by Green Dot in 2012. (en.wikipedia.org)
Altman’s career connects startup investment with the financing and commercial deployment of artificial intelligence. During his leadership, OpenAI released ChatGPT in November 2022 and expanded its partnerships and computing infrastructure. His removal and subsequent reinstatement as chief executive in November 2023 also brought public attention to the organization’s governance. Beyond OpenAI, his activities include energy investments, the digital-identity venture originally known as Worldcoin, and participation in public discussions about AI regulation. (openai.com)
Early life and education
Samuel Harris Altman was born on April 22, 1985, in Chicago, Illinois, and grew up in the St. Louis area of Missouri. He was the eldest of four children in a Jewish family. His mother, Connie Gibstine, was a dermatologist, and his father, Jerry Altman, worked in real estate. His childhood and secondary education were centered in the Midwest, before he moved to California to attend university. (biography.com)
Altman’s interest in computing developed in elementary school. At eight, he received an Apple Macintosh and began learning to program and to take apart computer hardware. These activities involved both writing software and examining the physical components of a computer. In Tad Friend’s 2016 profile in The New Yorker, Altman also recalled the importance of AOL chat rooms during his adolescence: online communication gave him opportunities to discuss being gay beyond his immediate surroundings. His early use of the internet thus had a social as well as a technical dimension. (biography.com)
He attended John Burroughs School, a private college-preparatory school in Ladue, Missouri, in the St. Louis metropolitan area, graduating in 2003. Biographical accounts describe his continuing interest in computers during these years, including a friendship with a computer-science teacher who shared his interest in the future of artificial intelligence. Another documented episode concerned a school assembly about sexuality. After some students objected to a National Coming Out Day speaker, Altman addressed the school community, publicly identified himself as gay, and argued for openness toward different ideas. His college counselor, Madelyn Gray, later recalled the speech as significant for other students who had not felt able to speak openly about themselves. (en.wikipedia.org)
In 2003, Altman enrolled at Stanford University to study computer science. While at Stanford, he developed an interest in poker, which he later credited with teaching him about psychology and decision-making under risk. By this period, he intended to become an entrepreneur. He left Stanford in 2005, after approximately two years of undergraduate study, without completing a bachelor’s degree. His departure was connected to work on Loopt, a location-sharing service he co-founded with Nick Sivo; the company became the starting point of his business career rather than a continuation of his formal education. (time.com)
Loopt and the beginning of his business career
In 2005, Altman co-founded Loopt with Nick Sivo; Alok Deshpande was also among the company’s founders. Altman served as chief executive. The company developed a location-sharing service that allowed mobile-phone users to see selected friends on a map and arrange meetings when they were nearby. Its central function was selective sharing within a social network, rather than public broadcasting of a person’s whereabouts. The early product used phones’ location capabilities to connect online communication with face-to-face encounters. (en.wikipedia.org)
Loopt received backing from Y Combinator in the accelerator’s first cohort, in summer 2005. This established Altman’s connection with the organization as a founder receiving investment and support, years before he joined its leadership. In his February 21, 2014 announcement appointing Altman president, Y Combinator co-founder Paul Graham specifically recalled that Altman had participated in the first group of companies funded in 2005. Loopt therefore provided the original institutional link between Altman’s work as a startup operator and his subsequent career supporting other founders. (ycombinator.com)
The service expanded through partnerships with mobile carriers and support for additional devices. In testimony before a U.S. House subcommittee in April 2009, Loopt’s chief privacy officer, Anne Collier, reported more than one million registered users and over 40 employees. She described availability across six wireless networks, including AT&T Mobility, Sprint Nextel, and Verizon Wireless, and on the iPhone, BlackBerry, and Android G1. Depending on the device and carrier, access ranged from a free, advertising-supported service to a subscription costing $3.99 per month. Interactive maps displayed friends’ locations, while users could also share location updates with other social networks. These figures were company-reported registrations, not a measure of daily active use. (govinfo.gov)
In March 2012, banking and payments company Green Dot agreed to acquire Loopt in a transaction announced at approximately $43.4 million. The terms distinguished payments to shareholders from incentives intended to retain employees: Green Dot’s securities filing specified a $40 million base amount, subject to a working-capital adjustment expected not to exceed $3.4 million, with approximately $9.8 million allocated to a retention pool for key staff. Its subsequent annual report recorded approximately $33.6 million paid for Loopt’s outstanding shares and $9.8 million in retention-based incentives. The widely reported $43.4 million figure thus represented the overall transaction package, not Altman’s personal proceeds. (sec.gov)
The acquisition shifted Loopt’s personnel and technology toward Green Dot’s mobile-payments business rather than preserving the location-sharing service as an independent company. Y Combinator’s contemporary account stated that Loopt’s consumer products would be shut down and its approximately 30 employees would become Green Dot’s Silicon Valley mobile-product development team. Altman described the transaction as an opportunity to connect location-based offers and loyalty features with payments. Green Dot announced completion on April 4, 2012, stating that Loopt employees would remain at their Mountain View headquarters and be integrated into its information-technology organization. (ycombinator.com)
Leadership of Y Combinator
Altman’s role at Y Combinator (YC) developed from his participation as a founder in its first startup cohort in 2005. On June 13, 2011, YC announced that he had become one of four alumni recruited as part-time partners, alongside Garry Tan, Emmett Shear, and Justin Kan. Their work consisted of advising startups, with an expected commitment of one-fifth of their time. On February 21, 2014, Paul Graham announced that Altman would become president beginning with the next cohort. Graham retained a founder-advisory role through office hours, while Altman assumed leadership of the organization. Graham explicitly presented the succession as a means of expanding YC’s capacity to fund and support more startups. (ycombinator.com)
The presidency combined organizational leadership with YC’s model of financing companies and advising their founders. On April 22, 2014, Altman announced a simplified standard investment: $120,000 for a 7 percent ownership stake. This replaced a package averaging $17,000 for 7 percent plus an additional $80,000 through a financing instrument that converted on the terms of a subsequent funding round. Altman described the change as making founders’ eventual dilution easier to understand and providing money for business and living expenses. The investment accompanied intensive advice, access to other founders and investors, and continuing assistance after the initial three-month program; YC ran two cohorts annually. (ycombinator.com)
Expansion involved both greater scale and a division of responsibilities. In his February 2017 annual letter, Altman reported that YC had cumulatively funded 1,470 companies and more than 3,200 founders by January 1, 2017; these totals included companies supported before his presidency. The main program then funded approximately 125 companies per cohort. Michael Seibel had taken responsibility for that program as chief executive in October 2016, while Altman oversaw a broader organization. Another unit, YC Continuity, had been established in 2015 under Ali Rowghani to provide growth-stage financing to companies that had completed the accelerator. Altman reported approximately $27 million invested in the two 2016 cohorts and approximately $187 million in later-stage investments from the first Continuity fund. (ycombinator.com)
On October 7, 2015, Altman announced YC Research, a nonprofit laboratory intended to support research poorly suited to startup financing: projects with long time horizons, open-ended questions, or technologies that should not belong to a single company. He announced a personal commitment to donate $10 million and plans to raise additional money for particular research groups. This was distinct from YC’s equity investments: the stated purpose was not to increase the accelerator’s returns or benefit its portfolio companies. The proposed model emphasized small research groups, collaboration with outside institutions, and public release of work, subject to researchers’ readiness and safeguards for potentially dangerous technology. (ycombinator.com)
On March 8, 2019, Altman’s departure from the presidency was announced as allowing him to devote more time to OpenAI, with operational responsibilities passing to other YC partners. Contemporary reporting described an initial transition to chairman. On May 20, Altman announced Geoff Ralston as the new president; reporting accompanying that appointment clarified that Altman would instead serve as an adviser rather than retain the chairman title. (axios.com)
Founding OpenAI and becoming chief executive
OpenAI publicly announced its establishment as a nonprofit artificial intelligence research organization on December 11, 2015. Altman was a founding co-chair alongside Elon Musk, rather than its initial chief executive or research director. The founding leadership also included Greg Brockman as chief technology officer and Ilya Sutskever as research director; other founding researchers and engineers included John Schulman, Wojciech Zaremba, and Andrej Karpathy. Its announcement described an institution intended to advance intelligence for humanity’s benefit without an obligation to generate financial returns, encouraging researchers to publish papers, code, and other findings. Altman was among the supporters collectively announcing $1 billion in funding commitments—a pledged total, not money already received or spent. (openai.com)
The organization’s long-term objective became explicitly framed as ensuring that artificial general intelligence (AGI) benefited all humanity, principally through developing safe AGI and sharing its benefits. In March 2019, Altman became OpenAI’s chief executive, moving from his founding oversight role into full-time executive leadership. Brockman and Sutskever had encouraged him to join full time as the organization faced growing financial and managerial demands. His responsibilities centered on organizational direction, financing, and institutional partnerships; these were distinct from the scientific and engineering work undertaken by its research teams. The transition coincided with a restructuring designed to finance a substantially larger research effort. (openai.com)
On March 11, 2019, OpenAI announced OpenAI LP, a “capped-profit” entity under nonprofit control. Its stated rationale was that advanced AI research would require billions of dollars for computing, specialist recruitment, and supercomputers, exceeding what its original financing model could readily support. The arrangement allowed investors and employees to receive financial returns, but placed negotiated limits on those returns; the first investment round carried a ceiling of 100 times invested capital, with excess returns allocated to the nonprofit. This was a maximum contractual return, not a promised yield. The nonprofit retained control, and only a minority of its board could hold financial interests in the partnership. Directors without such interests were to decide matters where investor interests conflicted with the mission. These provisions described the structure adopted in 2019, rather than an unrestricted conversion into an investor-controlled company. (openai.com)
On July 22, 2019, Microsoft and OpenAI announced a partnership accompanied by a $1 billion Microsoft investment. The agreement linked financing to access to large-scale cloud computing: Microsoft would become OpenAI’s exclusive cloud provider, and the organizations would jointly develop Azure AI supercomputing technologies. Access to computing capacity mattered because OpenAI’s research strategy combined algorithmic improvements with increasingly computationally demanding training. The partnership therefore supplied both capital and an infrastructure-development relationship, rather than funding alone. OpenAI also identified Microsoft as its preferred partner for commercializing selected technologies developed before AGI. At that stage, it presented licensing as a way to finance research without immediately redirecting the organization toward building commercial products. (openai.com)
Product deployment, financing, and computing infrastructure
Under Altman’s leadership as chief executive, OpenAI released ChatGPT on November 30, 2022, as a free research preview. Its conversational interface allowed users to ask questions, request revisions, and pursue follow-up exchanges without integrating a model into their own software. The release therefore extended access beyond developers to a broader consumer audience, while giving OpenAI feedback about the system’s capabilities and limitations. OpenAI described ChatGPT as a product of model training, human feedback, and engineering work; Altman’s executive role should be distinguished from the contributions of the research and product teams that developed it. The launch documentation also acknowledged problems including plausible but incorrect answers and sensitivity to the wording of prompts. (openai.com)
Consumer access complemented an existing developer business. OpenAI had introduced its application programming interface in June 2020, enabling outside developers to incorporate its models into their own applications rather than build and train comparable systems themselves. In his 2023 Senate testimony, Altman presented free access, subscriptions, and APIs as parallel channels for distributing the company’s technology. ChatGPT Plus, announced on February 1, 2023, added a recurring subscription initially priced at US$20 per month, with faster responses, access during periods of high demand, and priority access to improvements. These channels served different commercial purposes: subscriptions sold enhanced access to OpenAI’s own interface, while APIs made its models components of other companies’ products and services. (openai.com)
The launch of ChatGPT Enterprise on August 28, 2023, extended this approach to organizational purchasing and deployment. Its initial offering combined GPT-4 access with administrative controls, single sign-on, longer input capacity, and commitments not to train models on customers’ business data or conversations. OpenAI reported that registered ChatGPT accounts appeared in more than 80 percent of Fortune 500 companies, defining this figure through corporate email domains; it was not a count of paid enterprise contracts. The enterprise product sought to turn individual workplace use into managed organizational adoption, addressing purchasing requirements concerning security, data privacy, and account administration. (openai.com)
Financing and computing capacity developed alongside these distribution channels. On January 23, 2023, OpenAI and Microsoft announced a multiyear, multibillion-dollar investment, following Microsoft’s investments in 2019 and 2021; their announcements did not disclose an exact amount. The arrangement joined financing to cloud computing: Microsoft committed to expanding specialized supercomputing systems, and Azure was designated at that time as the exclusive provider for OpenAI’s research, API, and product workloads. The partnership also distributed OpenAI models through Azure OpenAI Service and incorporated its technology into products such as GitHub Copilot. For Altman’s expansion strategy, the relationship supplied both capital and infrastructure for training models and operating them for users, rather than financial backing alone. (openai.com)
On January 21, 2025, OpenAI announced the Stargate project, a new company intended to invest US$500 billion over four years in AI infrastructure in the United States, with an initial US$100 billion deployment planned. Its initial equity funders were SoftBank, OpenAI, Oracle, and MGX. SoftBank assumed financial responsibility and OpenAI operational responsibility, with Masayoshi Son named chairman; Arm, Microsoft, NVIDIA, Oracle, and OpenAI were identified as initial technology partners. The announcement stated that construction was underway in Texas and that other sites were being evaluated. The spending figures represented announced intentions, not completed expenditure. Stargate also did not signify an immediate abandonment of Microsoft’s infrastructure: the announcement explicitly anticipated increased Azure consumption alongside the additional computing capacity. (openai.com)
Removal, reinstatement, and subsequent governance changes
On November 17, 2023, the board of OpenAI’s nonprofit governing entity removed Altman as chief executive and from the board of directors, appointing chief technology officer Mira Murati as interim CEO. The board stated that Altman had not been “consistently candid in his communications,” which it said had impaired its oversight, and that it no longer had confidence in his leadership. These were the board’s stated reasons, not independently established findings accompanying the announcement. The same announcement removed Greg Brockman as board chair while initially retaining him as president; he subsequently resigned. (openai.com)
The following days brought negotiations, another interim appointment, and employee demands for Altman’s return. Late on November 19, the board selected former Twitch chief executive Emmett Shear to replace Murati as interim CEO. On November 20, Microsoft chief executive Satya Nadella announced plans for Altman and Brockman to lead a new advanced-AI research team at Microsoft. Nearly all of OpenAI’s more than 700 employees threatened to leave unless the board resigned and reinstated them, according to a letter reviewed by Reuters. Late on November 21, U.S. Pacific time, OpenAI announced an agreement in principle for Altman to return, with an initial board comprising Bret Taylor as chair, Larry Summers, and continuing director Adam D’Angelo. This agreement preceded the company’s formal November 29 announcement confirming Altman’s return as CEO, Murati’s resumption of the CTO role, and Brockman’s return as president. Altman did not immediately regain a board seat. (investing.com)
On March 8, 2024, OpenAI announced the completion of a review conducted by the law firm WilmerHale, which a special board committee had retained on December 8, 2023. According to the committee’s published summary, the firm examined more than 30,000 documents and conducted dozens of interviews. The summary attributed the dismissal to a breakdown of trust between Altman and the former board, rather than concerns about product safety, development speed, finances, or representations to investors and business partners. It also reported that the former board had authority to dismiss him, but that his conduct did not require removal. These conclusions were presented through OpenAI’s board-commissioned summary, rather than a published full investigative report or a judicial determination. (openai.com)
The March announcement also restored Altman to the board and added Sue Desmond-Hellmann, Nicole Seligman, and Fidji Simo as directors. Alongside those appointments, OpenAI announced corporate-governance guidelines, a strengthened conflict-of-interest policy, an anonymous whistleblower hotline for employees and contractors, and additional board committees, including a Mission & Strategy Committee. These changes addressed board membership and oversight procedures separately from Altman’s already-restored executive responsibilities. (openai.com)
On October 28, 2025, OpenAI announced a completed recapitalization under which its nonprofit became the OpenAI Foundation and its commercial subsidiary became OpenAI Group PBC, a public benefit corporation. The Foundation retained control through exclusive voting and governance rights allowing it to appoint and replace every Group director; control therefore did not depend on majority equity ownership. At closing, the Foundation held 26% of Group equity, valued at approximately $130 billion, while Microsoft held roughly 27%. OpenAI’s published governance structure lists Altman as CEO and a Foundation director, distinct from its independent directors. It also provides that Foundation directors serve on the Group board, except for specified directors assigned exclusively to nonprofit oversight. Altman’s executive and board positions thus remained subject to the Foundation’s institutional control. (openai.com)
Investment activities and energy ventures
Altman established Hydrazine Capital in 2012 with his brother Jack Altman, creating an investment business separate from his subsequent leadership of OpenAI. He put some of his proceeds from the sale of Loopt into its initial $20 million venture fund. Hydrazine provided a vehicle for investing in startups using pooled capital, while Altman also continued making personal investments. These activities should be distinguished from OpenAI’s corporate investments and procurement: an ownership stake held by Altman or an investment fund is not an investment by OpenAI, and financing an energy developer is different from contracting to purchase its future electricity. (en.wikipedia.org)
One of his largest personal investments was in Helion Energy, a company developing nuclear fusion technology. On November 5, 2021, Helion announced a $500 million Series E financing round led by Altman; his personal contribution was reported as $375 million. Other participants included Dustin Moskovitz, Mithril Capital, and Capricorn Investment Group. The financing also included the possibility of another $1.7 billion tied to performance milestones, rather than an unconditional payment of that additional amount. Helion identified Altman as its chairman since 2015 and announced his expanded role as executive chairman in connection with the financing. (time.com)
Helion intended to use the financing to complete Polaris, its seventh-generation experimental fusion generator. Its approach uses repeated magnetic pulses to form, merge, and compress plasmas, with a design intended to recover energy directly as electricity. The 2021 announcement set a target of demonstrating net electricity production in 2024; that was a development objective, not a result established by the fundraising. A separate commercial step followed on May 10, 2023, when Helion announced an electricity-purchase agreement with Microsoft. The announced schedule envisaged initial operation in 2028 and output of at least 50 megawatts after a one-year ramp-up. Microsoft—not OpenAI—was the named purchaser, and the agreement concerned prospective supply rather than electricity already being delivered. (helionenergy.com)
Altman also backed Oklo, where he became chairman in 2015. Unlike Helion, Oklo develops fast-reactor technology based on nuclear fission. Its proposed business model was to build and operate power plants and sell electricity directly to customers, rather than simply sell reactor equipment. Altman participated in its public-market financing through AltC Acquisition Corp., the acquisition company he co-founded and led as chief executive. Oklo completed its merger with AltC on May 9, 2024, and began trading on the New York Stock Exchange the following day under the symbol OKLO. The transaction provided approximately $306 million in gross proceeds to Oklo; this was corporate financing, not a measure of Altman’s personal investment or proceeds. (oklo.com)
On April 22, 2025, Oklo announced Altman’s departure as chairman, with co-founder and chief executive Jacob DeWitte succeeding him. Its securities filing specified that Altman’s resignation as chairman, director, and member of the nominating and corporate-governance committee took effect that day, and stated that it did not arise from a disagreement over company operations, policies, or practices. The announcement placed the transition alongside Oklo’s exploration of partnerships with artificial-intelligence companies, potentially including OpenAI. That reference described a possible commercial relationship, not an announced OpenAI investment or completed electricity-supply agreement. (sec.gov)
Tools for Humanity and World
Altman co-founded Tools for Humanity in 2019 with Alex Blania and Max Novendstern to develop technology for a global identity and financial network. Altman became the company’s chairman, while Blania served as chief executive. The privately held technology company is distinct from both the network’s open-source protocol and its independent foundation. Tools for Humanity developed the initial protocol and supported its testing, then transferred stewardship to the foundation before the public launch in July 2023. It continued providing software development, hardware manufacturing, and operational support under governance separate from the foundation’s. (world.org)
The project’s stated objective was to let people demonstrate that they were unique human beings online as artificial intelligence made automated accounts and synthetic content increasingly difficult to distinguish from human activity. Its principal verification device, the Orb, photographs a person’s irises and processes their distinctive patterns into a numerical representation used to check whether that person has already registered. The resulting World ID is intended to establish personhood and uniqueness rather than disclose a name or conventional civil identity. When using the credential, users generate zero-knowledge proofs—a technique in cryptography designed to demonstrate that they possess a valid credential without revealing the underlying biometric information to the service requesting verification. These are the system’s intended technical functions, rather than guarantees that all risks associated with biometric collection have been eliminated. (world.org)
World ID and the Worldcoin token, identified by the ticker WLD, perform different roles. World ID is the verification credential; WLD is a transferable digital asset associated with the network. In their July 24, 2023 launch letter, Altman and Blania described token distribution to verified participants where local rules permitted it, alongside World App, the first wallet compatible with the protocol. They presented the network as a possible foundation for distributing economic benefits from AI, including a potential route to AI-funded basic income. This was an aspiration stated by the founders, not an established income-distribution program. (world.org)
On October 17, 2024, Altman and Blania presented an expanded Orb and software offering at an event in San Francisco, where the broader project changed its name from Worldcoin to World, also called World Network. The rebranding distinguished the identity and network infrastructure from its cryptocurrency component; the token retained the Worldcoin name and WLD ticker. At the time, the company reported that more than 6.9 million people had undergone iris scanning since the July 2023 launch. That figure represented reported participation, not an independent assessment of the system’s reliability or privacy protections. (world.org)
Biometric collection also brought regulatory intervention. On March 6, 2024, Spain’s data-protection authority, the AEPD, announced a precautionary order requiring Tools for Humanity Corporation to stop collecting and processing personal data in Spain and to block data already collected. The authority cited complaints concerning insufficient information, the collection of minors’ data, and obstacles to withdrawing consent. Issued under Article 66(1) of the European Union’s General Data Protection Regulation, the temporary measure applied within Spain for a maximum of three months, rather than constituting an EU-wide prohibition. Worldcoin disputed the regulator’s characterization of its practices. The action concerned the company’s processing of personal data and did not establish personal wrongdoing by Altman. (aepd.es)
Public testimony and positions on artificial intelligence
On May 16, 2023, Altman appeared as OpenAI’s chief executive before the U.S. Senate Judiciary Subcommittee on Privacy, Technology, and the Law at the hearing “Oversight of A.I.: Rules for Artificial Intelligence.” Chaired by Senator Richard Blumenthal, with Josh Hawley as ranking member, the hearing examined safeguards for artificial intelligence. Altman testified as an industry witness alongside IBM chief privacy and trust officer Christina Montgomery and New York University professor emeritus Gary Marcus. It was his first testimony before Congress; his statements combined accounts of OpenAI’s practices with proposals for public oversight. (judiciary.senate.gov)
Altman advocated a regulatory framework directed particularly at highly capable models. His written testimony proposed that the U.S. government consider licensing or registration requirements for developing and releasing models above a specified capability threshold, supported by internal and external testing before release and publication of evaluation results. In questioning by Senator John Kennedy, he outlined three measures: an agency empowered to issue and revoke licenses, safety standards based on evaluations of dangerous capabilities, and independent audits of compliance. As an example of a capability requiring examination, he identified whether a model could replicate itself and escape its controlled environment. These were proposed regulatory mechanisms, not requirements established by the hearing. (openai.com)
His proposals distinguished oversight of future powerful systems from controls on existing products. Responding to Senator Mazie Hirono, Altman said that his rationale for a licensing regime concerned progress toward artificial general intelligence rather than the capabilities of then-current models. He separately supported clearly identifying generated images as artificial. His written testimony called for standards that could be revised as technology changed, with participation from multiple expert groups, and for international cooperation on licensing, safety standards, and possible intergovernmental oversight. These positions placed both developer testing and external institutions within his proposed accountability framework. (govinfo.gov)
Altman presented potential benefits alongside acknowledged limitations. His written submission described applications in education, accessibility, and professional work, while identifying inaccurate outputs, discriminatory bias, disinformation, and cybersecurity misuse as safety concerns. It cited Khan Academy’s development of an AI tutoring and teaching assistant as an application requiring tailored safeguards. In discussing independent assessment, he reported that the Alignment Research Center had conducted a preliminary evaluation of GPT-4’s capacity for certain autonomous actions before release. These examples were accounts supplied in his testimony, rather than findings independently established by the subcommittee. (judiciary.senate.gov)
On the labor market, Altman forecast a combination of increased productivity, job creation, changes to existing occupations, and displacement through automation. He distinguished performing tasks from replacing entire jobs, while acknowledging that some jobs could disappear and that the overall effects were difficult to predict. His written testimony offered cooperation with government through data sharing and economic research, and described support for studying measures such as modernized unemployment insurance, adjustment assistance, and worker education. These statements expressed expectations and proposed responses to technological change, not measured economy-wide employment outcomes attributable to OpenAI’s products. (govinfo.gov)
Personal life, philanthropy, and public recognition
Altman is married to Oliver Mulherin, an Australian software engineer. Their marriage became public in January 2024, when Altman confirmed it in a text message to NBC News after photographs of the ceremony circulated online. NBC described a small seaside wedding, with photographs showing the couple and about a dozen guests at a tropical beach location. The confirmation established the marriage without publicly identifying the ceremony’s location. Mulherin subsequently joined Altman as a signatory to their shared philanthropic commitment. (tech.yahoo.com)
In a joint letter dated May 18, 2024, Altman and Mulherin joined the Giving Pledge, committing to give the majority of their wealth to charitable causes. The initiative, established in 2010 by Warren Buffett, Bill Gates, and Melinda French Gates, allows participants to fulfill that commitment during their lifetimes or through their wills. Its mechanism is a public promise, accompanied in many cases by a letter explaining the signatories’ motivations and intended priorities; participants determine when and how to carry it out. The couple’s enrollment therefore documented an intention concerning the future disposition of their wealth, rather than a completed donation of a specified sum. Their letter did not identify a monetary target, named recipients, or a schedule of disbursements. (givingpledge.org)
The letter attributed their ability to make the pledge to the work and generosity of others and to the accumulated social foundations that had enabled their success. They presented their giving as a way to extend those foundations for future beneficiaries. Their stated priority was to support technology that could create greater abundance for people, enabling those people in turn to contribute to further progress. This was a broad statement of philanthropic purpose, not an announcement of a particular grant program or a report of demonstrated results. The published letter did not allocate funds among specific technologies or charitable organizations. (givingpledge.org)
Altman’s public recognition included several editorial selections by TIME in 2023. He appeared in the magazine’s annual TIME100 list and in its separate TIME100 AI selection. On December 6, 2023, TIME named him its CEO of the Year. The accompanying profile examined his prominence following the widespread adoption of ChatGPT, alongside the leadership crisis surrounding his removal and reinstatement at OpenAI that November. These designations were selections by the magazine, rather than standardized measures of executive performance or findings about the safety or social effects of artificial intelligence. The CEO of the Year designation was distinct from TIME’s Person of the Year, which went to Taylor Swift in 2023. (time.com)
