Sam Altman

Altman is based in San Francisco, California, where OpenAI is headquartered. He has been publicly associated with the city for most of his career in tech. His precise residential address is private and not something we report.

Sam Altman is American. He was born in Chicago, Illinois, and grew up in St. Louis, Missouri.

Sam Altman was born on April 22, 1985, which makes him 41 years old as of mid-2026. He became one of the most powerful figures in tech well before turning 40.

Altman's exact height has not been officially confirmed by him or any reliable source, so we won't guess. He appears average height in public appearances, but that's as far as verified information goes.

Elon Musk, and it's not remotely close. Musk is consistently ranked among the top one or two wealthiest people on the planet, with a fortune widely reported in the hundreds of billions of dollars. Altman's disclosed holdings, per May 2026 court filings, exceed $2 billion, substantial, but a different league entirely.

Yes. Sam Altman is openly gay and is in a long-term relationship with Oliver Mulherin, an Australian engineer. Altman has been public about his relationship and his sexual orientation for years.

Altman's partner is Oliver Mulherin, an Australian software engineer. Altman has referred to Mulherin publicly, and the two have been together for a number of years. Whether they are legally married has not been confirmed in reliable public sources.

Altman is in a committed relationship with Oliver Mulherin. A formal legal marriage has not been publicly confirmed or reported by reliable sources as of the time of writing, so we flag that as unconfirmed.

Altman has described himself publicly as Jewish. He has not made detailed public statements about the depth or practice of his faith, so beyond that self-identification, further characterisation would be speculation.

Sam Altman does not have a wife, he is openly gay and his long-term partner is a man named Oliver Mulherin. This is well-documented in public reporting.

According to May 2026 court filings, Altman's disclosed holdings exceed $2 billion, with roughly $1.7 billion of that tied to his stake in Helion Energy, a nuclear-fusion company. Notably, those same filings show he holds no direct equity in OpenAI. These are reported figures from a specific legal filing, not a certified total, and his actual net worth could differ.

Sam Altman is Jewish, as he has stated publicly. He has not made extensive public statements about his religious practice or observance beyond that identification.

A formal marriage between Sam Altman and his partner Oliver Mulherin has not been publicly confirmed or reported by reliable sources. We will not state a date that has not been verified.

Sam Altman is openly gay, that's simply who he is. He has been public about his sexual orientation for years and is in a long-term relationship with Oliver Mulherin. Whether a formal marriage has taken place has not been confirmed publicly.

There is no widely reported or publicly confirmed information about Sam Altman having a child as of the time of writing. We will not report this as fact without verified sourcing, if this has changed, treat it as unconfirmed until reported by reliable outlets.

Sort of, here's what's confirmed. Altman is in a long-term committed relationship with Oliver Mulherin. A formal legal marriage has not been publicly confirmed in reliable reporting, so we flag the marriage status itself as unconfirmed, while the relationship is well-documented.

The beef is real and has multiple layers. Musk was an early backer and board member of OpenAI but left in 2018; he later claimed the organisation had abandoned its founding nonprofit, safety-first mission and turned into a capped-profit company beholden to Microsoft. He filed a lawsuit against OpenAI and Altman, alleging breach of their original charitable agreement. Beyond the legal dispute, the two are direct competitors, Musk founded his own AI company, xAI, and Musk has repeatedly attacked Altman on social media. Altman has largely responded with public calm, which seems to irritate Musk further.

According to May 2026 court filings, Sam Altman holds no direct equity in OpenAI. That's the verified fact on record, and it surprises almost everyone who hears it. He has said publicly that he expects to receive equity as part of a restructuring of OpenAI into a for-profit entity, but that deal had not been finalised as of those filings.

Not from OpenAI, at least not yet. His disclosed wealth, per May 2026 court filings, is built primarily on his roughly $1.7 billion stake in Helion Energy, a nuclear-fusion startup he invested in and backed heavily. He also accumulated wealth through early-stage investments and his time at Y Combinator, where he had access to equity in many startups. His OpenAI equity situation is a pending, unresolved matter tied to the company's ongoing restructuring.

In November 2023, OpenAI's board fired Altman, citing a lack of candour in his communications with the board, a vague charge that was never fully elaborated publicly. The move backfired spectacularly: nearly all OpenAI employees threatened to quit, and major investor Microsoft was blindsided. Within days, Altman was reinstated as CEO and most of the board members who fired him were replaced. The episode was widely read as a clash between OpenAI's original safety-focused nonprofit culture and the commercial powerhouse it had become under Altman's leadership.
