Samuel Harris Altman was born in Chicago, Illinois, and is an American citizen.
Sam Altman Early Life
Samuel Harris Altman was born on April 22, 1985, in Chicago, Illinois. His family soon moved to Clayton, Missouri, a suburb of St. Louis, where he spent most of his childhood. He grew up as the eldest of four children in a Jewish American household. His mother, Connie Gibstine, worked as a dermatologist. His father, Jerry Altman, worked as a real estate broker and passed away in 2018. His siblings are brothers Max and Jack and sister Ann, sometimes referred to as Annie.
The family maintained close ties, often sharing dinners and playing games together. Altman showed an early aptitude for numbers and machines. At the age of eight he received an Apple Macintosh computer. He taught himself to write code and took the machine apart to understand its hardware. He has described those years as the glory days of personal computing, when experimentation felt immediate and open.
He attended John Burroughs School, a private preparatory institution in Ladue, Missouri. During his teenage years he came to terms with his sexuality. Growing up gay in the Midwest in the early 2000s presented challenges. He has spoken about finding support in early online chat rooms. At school he addressed an assembly after a Christian group objected to a discussion of sexuality. He publicly identified as gay and encouraged teachers to display Safe Space signs. A college counselor later observed that the moment changed the school culture.
Altman developed a lasting interest in technology and large-scale problem solving during these years. His paternal great-grandfather was born in Płock, Poland, adding a layer of family history that connected him to broader Jewish traditions of inquiry and improvement of the world.
Sam Altman Personal Life
Altman has lived much of his adult life in the San Francisco Bay Area. He maintains homes in the Russian Hill neighborhood of San Francisco and spends time in Napa, California. He also owns property in Hawaii and has referenced a parcel of land in Big Sur. In earlier years he spoke openly about practical preparedness, noting holdings of guns, gold, medical supplies, and other provisions as a form of personal contingency planning.
He is openly gay and has discussed the process of coming out as formative. For many years he kept romantic relationships relatively private. In 2015 he met Oliver Mulherin, an Australian software engineer who had studied computer science at the University of Melbourne and later worked on AI-related projects and at companies including Meta. The two connected at a party and later began a relationship.
They married in January 2024 in a private ceremony at their estate in Hawaii that included Jewish elements such as the breaking of a glass. The couple welcomed a son in 2025 through surrogacy. The child was born prematurely and spent time in neonatal intensive care before recovering. Altman has described becoming a father as the most meaningful experience of his life and has said it has reframed his sense of long-term responsibility.
In May 2024 Altman and Mulherin signed the Giving Pledge, committing to give away the majority of their wealth over time. They have indicated an interest in supporting technology that creates broader abundance for people.
Sam Altman Age
As of October 2026, Sam Altman is 41 years old. He was born on April 22, 1985.
Sam Altman Education
Altman enrolled at Stanford University in 2003 to study computer science. He spent two years there and worked in the university’s artificial intelligence laboratory. He later reflected that he learned as much from informal activities such as poker games with classmates as from formal lectures. Poker, he has said, taught him to recognize patterns in people and to make decisions under imperfect information.
In 2005, at age 19, he left Stanford without completing a degree. He has described the decision as driven by the opportunity to work full time on a startup rather than by any lack of interest in the subject. The choice aligned with a broader pattern among certain technology founders of that era who prioritized building companies over formal credentials.
Sam Altman Career
Loopt
While still connected to Stanford, Altman co-founded Loopt, a location-based social networking application. The idea allowed users to share their whereabouts with friends on early smartphones. Loopt joined the first cohort of startups funded by Y Combinator in 2005. The company raised more than 30 million dollars from investors that included Sequoia Capital and New Enterprise Associates. Altman served as chief executive.
Loopt operated for several years in a competitive mobile landscape. In March 2012 the company was acquired by Green Dot Corporation for 43.4 million dollars. Altman has noted that the experience taught him persistence and the practical realities of scaling consumer technology.
Y Combinator
After the Loopt acquisition Altman remained active in the startup ecosystem. In 2011 he began working part-time as a partner at Y Combinator. In 2012 he co-founded the venture fund Hydrazine Capital with his brother Max. In 2014, at age 28, he succeeded Paul Graham as president of Y Combinator. Under his leadership the accelerator expanded its reach, funded a larger number of companies, and solidified its reputation as a leading startup program. During this period Altman also taught a lecture series at Stanford titled “How to Start a Startup.”
He transitioned to chairman of Y Combinator in 2019 to focus more fully on other projects and fully stepped away from formal roles around 2020.
OpenAI
In December 2015 Altman co-founded OpenAI as a nonprofit research organization dedicated to developing artificial intelligence that benefits humanity as a whole. Early co-chairs included Altman and Elon Musk. Founding participants and early supporters included Greg Brockman, Ilya Sutskever, and others from research and industry backgrounds. The organization received initial commitments totaling about one billion dollars from a group of donors that included Altman, Musk, Peter Thiel, and Amazon Web Services.
OpenAI began with a research focus. Over time it created a capped-profit subsidiary to attract the capital required for large-scale model training while retaining nonprofit governance. Altman became chief executive in 2019. The company released a series of language models that demonstrated steadily increasing capability. In November 2022 it launched ChatGPT, a conversational interface that reached millions of users within weeks and brought generative AI into mainstream public awareness.
Partnerships with Microsoft provided cloud computing resources and significant investment. OpenAI continued to release more capable models and expanded into areas such as image generation and multimodal systems. In November 2023 the nonprofit board removed Altman as chief executive, citing a loss of confidence in his communications. The decision triggered widespread employee and investor concern. Within days Altman was reinstated and the board was restructured. The episode highlighted tensions between rapid commercialization and long-term safety considerations that had existed within the organization.
By 2025 and 2026 OpenAI had grown into one of the most closely watched technology organizations in the world. Altman has continued to emphasize the dual goals of advancing capability and ensuring systems remain under human control and aligned with human values. He has spoken publicly about the need for careful governance as models approach or exceed human performance on difficult intellectual tasks.
Other Roles and Investments
Altman has served as chairman of Helion Energy, a nuclear fusion company he first supported around 2015. He has invested substantial personal capital in the firm and has described fusion as essential to powering the energy demands of advanced AI systems. In 2026 he stepped down from the Helion board to avoid potential conflicts as OpenAI explored energy partnerships. He has also invested in companies such as Reddit, Stripe, and longevity research efforts including Retro Biosciences. Through Hydrazine Capital and personal angel investing he has backed a wide range of technology companies over more than a decade.
Sam Altman Family
Altman’s immediate family includes his mother Connie Gibstine, who continues to practice dermatology, and his late father Jerry Altman. His brothers Max and Jack have also been active in technology and investment. Max co-founded Hydrazine Capital with him. His sister Ann completes the sibling group. The family has remained connected despite the geographic distance created by Altman’s career in California.
His husband Oliver Mulherin and their young son form the center of his current household. Altman has spoken about the ways parenthood has shifted his perspective on long-term risk and responsibility.
Sam Altman Philosophy
Altman has consistently framed artificial intelligence as a technology of profound dual potential. He believes artificial general intelligence, systems that can match or surpass human capability across a wide range of cognitive tasks, is both achievable and desirable if developed with care. He has stated that the goal is to put powerful tools in the hands of people so that individuals gain greater agency over their lives.
He has described himself as being on “Team Human,” prioritizing human flourishing over purely digital forms of intelligence. At the same time he has acknowledged that the risk of losing control of advanced systems is real and non-zero. He argues for continued progress paired with serious investment in alignment research, monitoring, and governance. He has called for thoughtful regulation that protects society without stifling beneficial innovation.
In public remarks, including addresses at international forums, he has emphasized that people must remain at the center of decision-making as AI systems grow more capable. He views the distribution of benefits as a core part of the mission: the technology should create abundance rather than concentrate power. His early interest in universal basic income reflected a belief that automation would reshape labor markets and that societies would need new mechanisms for sharing prosperity.
Jewish cultural ideas of repairing the world have also informed his outlook. He has connected personal identity and family history to a broader sense of responsibility for large-scale outcomes.
