OMAHA, Neb. — An anonymous bidder offered more than $4.5 million to have a private lunch with billionaire investor Warren Buffett, shattering the previous record of nearly $3.5 million set in 2012 and 2016.

An online auction that raises money for the Glide Foundation’s work to help people who are homeless in San Francisco ended Friday night on eBay with a winning bid of $4,567,888.

It’s the 20th year the Berkshire Hathaway CEO from Omaha has participated in the pricey lunch auction, giving the winner the chance to talk with the renowned investor and philanthropist. Bidding starts at $25,000, and the auction has only finished below $2 million once since 2010. Buffett has raised nearly $30 million for the charity over the years.

The winning bidder and up to seven friends get to dine with Buffett at Smith & Wollensky in New York City.
