Tom Steyer Net Worth

Tom Steyer has an estimated net worth of $2.4 billion, according to Forbes Real-Time Billionaires, Tom Steyer profile (figures as of October 20, 2026). That is up from $1.6 billion in 2019.

Tom Steyer is an American investor, environmental advocate, and political donor who built his fortune in finance. He started his career at Morgan Stanley in 1979, then worked at Goldman Sachs from 1983 to 1985 and later at Hellman & Friedman. In 1986, he launched Farallon Capital in San Francisco. Forbes says Steyer was self-made, and it now estimates his net worth at $2.4 billion on its real-time billionaires tracker as of October 20, 2026.

Farallon became the center of Steyer's wealth. He ran the hedge fund for 26 years and sold his stake in 2012. After leaving the firm, he shifted toward climate work, politics, and philanthropy. He founded NextGen Climate and later co-founded Galvanize Climate Solutions in 2021, a climate-focused investment firm. He also wrote Cheaper, Faster, Better: How We’ll Win the Climate War, which reached The New York Times Best Seller list in 2024.

How Tom Steyer built his fortune

Steyer made his money mainly through Farallon Capital, the hedge fund he founded in 1986. Before that, he learned the finance business at Morgan Stanley, Goldman Sachs, and Hellman & Friedman. Farallon was based in San Francisco and grew into a major investment firm during his time there. Wikipedia says the firm was managing $20 billion when he left, and Forbes says he spent 26 years running it before selling his stake in 2012.

His later work still connects to investing, but with a climate focus. In 2021, he co-founded Galvanize Climate Solutions with Katie Hall. Forbes also notes that he founded the environmental group NextGen Climate. Alongside business, he has put large sums into public life. Forbes says he spent over $320 million in federal elections since 2010, plus another $340 million on his own presidential campaign in 2020.

Where his money story stands now

Steyer's wealth is tied to the long run of Farallon and to the value of the stake he sold after stepping away in 2012. Forbes places him in the Finance & Investments category and says hedge funds are the main source behind his fortune. The same profile notes that he later turned much of his attention to politics and the environment, including clean energy efforts through NextGen Climate and Galvanize.

Forbes currently values Steyer at $2.4 billion on its real-time billionaires tracker as of October 20, 2026. His recent profile is not only about investing. Forbes says he announced a campaign for governor of California in Nov. 2025, and it also highlights his giving with his wife, Kat Taylor, including tens of millions of dollars to Stanford and Yale for advanced energy research.
