Robert Bass is an American investor whose wealth is tied to oil and a long run in private investing. His family fortune came from the West Texas Keystone Field, and he later built his own investment platform. In 1985, he started the Robert M. Bass Group as his personal investment company. It was renamed Keystone, Inc. in 1990. He also founded Oak Hill Capital Partners in 1986 as a family office.

He became widely known through large business deals and later through companies he helped launch. In 1987, he joined the buyout of Taft Broadcasting. In 1988, he sold the Plaza Hotel to Donald Trump for $390 million, led a buyout of Bell & Howell, and made an offer for Macmillan Inc. He also founded Aerion in 2003, an aerospace company focused on supersonic business jets, though it ceased operations in 2021.

How Robert Bass built his fortune

Bass's money comes from oil and investments. Forbes places him in the energy industry, and his family wealth traces back to an inheritance linked to oilman Sid Richardson. In 1959, Robert Bass and his brothers inherited $2.8 million each from their uncle. Over time, he moved beyond family wealth by creating his own investment firms and backing a range of deals through private capital.

A big part of his business career has been launching and supporting investment shops. Forbes notes that he helped start a half dozen firms, including Oak Hill Advisors. He is also the lead investor in the private equity portfolio managed by Oak Hill Capital. His record includes major transactions in media, publishing, hotels, and finance, including the Taft Broadcasting deal and the Plaza Hotel sale in 1988.

Other money moves and the latest Forbes estimate

Bass also put money into aviation. He founded Aerion in 2003 and served as its initial chairman. Boeing later invested several hundred million dollars for about 40 percent in 2019. Still, the company shut down in 2021 after it could not secure the estimated $4 billion needed for certification and production of its AS2 business jet. Forbes also notes that the startup collapsed in 2021 amid reported financial difficulties.

Forbes currently estimates Bass's net worth at $7.1 billion on its real-time billionaires tracker as of October 20, 2026. That wealth reflects a mix of inherited oil money, long-term investing, and stakes in private businesses. Outside business, he and his wife Anne have been major donors. Forbes says they have given at least $70 million to Duke and $55 million to Stanford.
