COLUMBIA, S.C. - Tom Steyer, the billionaire former hedge-fund executive whose prolific campaign spending altered the Democratic primary and allowed him to persist in the race, withdrew after an apparent third-place finish Saturday night in South Carolina.

The private home, owned by Steyer and his wife Kat Taylor, is located in the Glenbrook community on the east side of the lake, a popular tourist destination straddling California and Nevada.

The couple still owns a home in San Francisco's Sea Cliff neighborhood that they bought in 2014 for $6.75 million, according to public records. Mr. Steyer joined the presidential race in July 2019, and then quit the Democratic primary on February 29, 2020.

Current owners are Nora Lacey, founder of biotech company Cell Marque, and her husband, pathologist Dr. Michael Lacey.

San Francisco rounds out the top three. The city is home to 84 billionaires, one less than in 2021. Although San Francisco lost a billionaire, it saw a growth of 68% in its population of high-net-worth individuals from 2012 to 2022, according to a Henley & Partners report.

King Charles III To date, the title for the most expensive house in the world is held by the Buckingham Palace in London. The larger-than-life property (which cannot be sold) is over 200 years old and is currently owned by King Charles III after the demise of the Queen of England, Elizabeth II.

But neither one of them has bragging rights as the billionaire with the most homes. That title appears to belong to Oracle cofounder Larry Ellison, who owns an estimated two dozen homes, including three in Newport, Rhode Island; four in Woodside, California; and six in Malibu (where he also has a restaurant and spa).
