Warren Buffett, shown here at the 'Too Big to Fail' movie premiere in New York on May 16, has raised more than $2.3 million for his annual fundraising power lunch.
NEW YORK (CNNMoney) -- Bidding on Warren Buffett's auction of an annual fundraising power lunch easily eclipsed $2 million by Tuesday, with four days of bidding yet to go.
A special eBay page began accepting bids Sunday. The opening bid was $25,000, and after seven bids the going price reached $2,345,678 by Tuesday morning.
At the current pace, the bidding could exceed last year's record of $2.6 million.
The winner buys the opportunity to have lunch with Buffett, and up to seven guests of the winner's choice, at the Smith & Wollensky steak house in New York. The proceeds will go towards Glide, an organization that benefits poverty-stricken residents of the San Francisco Bay area.
Buffett, chairman of investment firm Berkshire Hathaway (BRKA, Fortune 500), is a billionaire and philanthropist who famously gave much of his wealth to another billionaire philanthropist: Microsoft (MSFT, Fortune 500) co-founder Bill Gates, of the Bill & Melinda Gates Foundation.
Bidding will continue until Friday at 10:30 p.m. ET.
The timing of the lunch is agreed upon by Buffett and the winning bidder.
