Lunch With Warren Buffett? That'll Be $3.5 Million

It's probably safe to say this is someone who would qualify for the "Buffett rule": An anonymous bidder is forking over nearly $3.5 million to have lunch with billionaire investor Warren Buffett.

According to the Associated Press, it's part of an annual charity auction Buffett takes part in every year to raise money for the Glide Foundation, which helps the homeless in San Francisco. This year's winning bid was a record-breaking $3,456,789.

The Gilde Foundation said this year's winner has chosen to remain anonymous; 10 other people were actively involved in the bidding, which jumped in the auction's last hour from $1 million to the final $3.46 million.

Winning bids have topped $2 million every year for the last four years, setting records every time. Last year's winner paid $2,626,411 to break bread with Buffett.

Buffett has made news last year after he penned an op-ed for the New York Times calling for Congress to raise taxes on the wealthy. President Barack Obama subsequently took up the case for what became known as the "Buffett rule," which would have seen those making more than $1 million annually pay at least 30 percent of their income in taxes. The plan was derailed in the Senate in April.
