The Warren Buffett charity lunch auction is back and last chance

If you have been looking for a chance to break bread with Warren Buffett, this might be your last chance to fold his ears.

The 91-year-old billionaire raised money for charity by auctioning lunch with him, reviving an annual tradition after two years of scarcity due to the Covid-19 pandemic. And according to event partner, San Francisco-based nonprofit Glide, this charity lunch will be Buffett's last.

Buffett's annual "Power of One" charity auction dinner started in 2000 to raise money for Glide, which runs a church and provides food and health care to the poor and homeless. In its first year, the auction raised $25,000 from anonymous donors. In 2019, the winning bid was $4.57 million, placed by cryptocurrency entrepreneur Justin Sun in the last year of the event.

The organization said that the luncheon had raised more than $34 million for Glide. Glide announced this year's auction as the "final event." Buffett and Glide haven't publicly explained why the annual charity dinner ended. Still, a spokesperson for Glide told CNBC Make It in an email that "Mr. Buffett's intentional friendship with Glide will continue," even the lunch series is over.

Buffett's first wife, Susie, who died in 2004, originally planned the lunch auction. In 2017, Buffett told CNBC about his choice of Glide, noting that former pastor Cecil Williams "helped the people for whom he gave up the world, and he never gave up on anyone."

"They take people who have hit rock bottom and help bring them back," Buffett said. "And [Williams] has been doing this for decades, and he's an amazing guy, and if we can help by raising some money for him, I'm happy to do it."

On Monday, Glide President and CEO Karen Hanrahan praised Buffett's "friendship and generosity over the past 22 years" for "deepening Glide's impact on systems leading to poverty and inequality."
