Money will go to Glide, a San Francisco charity that provides food, health care and other services to people who are homeless, poor or struggling with substance abuse.
The five-day auction on eBay ended on Friday night. The winning bid matched the sum paid by an anonymous bidder in 2012, the most expensive single charity item sold on eBay.
Buffett has held 17 annual auctions for Glide, raising about $23.6 million.
The Rev. Cecil Williams, co-founder of Glide and pastor since 1963 of the Glide Memorial United Methodist Church, said Buffett’s involvement has attracted more interest in the charity, helping it fund its $17-million annual budget.
Glide provides services including an estimated 750,000 free meals, 815,000 syringes, and day care and after school programs for 450 children each year.
“This one was really one of the best we’ve had in my over 50 years,” Williams, 86, said after the auction.
The successful bidder and up to seven friends can dine with Buffett at the Smith & Wollensky steak house in Manhattan. All topics are fair game apart from where Buffett will invest next.
Buffett, 85, is the world’s third-richest person, worth $66.5 billion, Forbes magazine said.
He got rich building Berkshire Hathaway Inc into a conglomerate with roughly 90 businesses including insurance, energy, chemical, apparel and food companies, plus a railroad. Buffett is donating virtually all of his wealth to charity.
The auction was created by Buffett’s first wife, Susan, and continued after her death in 2004.
