No One Won Warren Buffett's $1 Billion Bracket Challenge

It’s over already.

The group offering $1 billion for the perfect March Madness bracket said late Friday that no potential winners remain after two major upsets busted almost every submitted bracket.

The contest by Quicken Loans, backed by Warren Buffett, said that 99 percent of brackets were eliminated on Friday after Dayton beat Ohio State and Mercer beat Duke in the college basketball tournament.

The final three brackets were eliminated after only 25 games when Memphis defeated George Washington Friday evening, the Associated Press reports.

The Quicken Loans Billion Dollar Bracket is still offering $100,000 each to the top twenty performing brackets.

“That’s still a heck of a payday for filing out a bracket,” Jay Farmer, president and chief marketing officer of Quicken Loans, said in a statement.
