Beyond San Francisco, Altman's portfolio includes:

  • A sprawling estate in Hawaii, acquired in 2021 for $43 million.
  • A ranch in Napa, California, purchased in 2020 for $15.7 million. This is where Altman and his husband, Oliver Mulherin, often spend their weekends.

Before his role at OpenAI, Altman founded Loopt, which he later sold for $43 million. He then established his venture capital fund, Hydrazine Capital. Forbes estimates Altman's net worth at $1.7 billion.
