Only 16 perfect brackets remain in the billion dollar bracket challenge put on by Quicken Loans and Warren Buffett.
The challenge is that anyone who chooses every single winner in the NCAA men’s basketball tournament correctly gets $1 billion. If more than one person succeeds the prize would be split.
However, with a series of upsets in the second round–most notably Duke falling to Mercer on Friday afternoon–only 16 perfect brackets remain, Quicken Loans announced.
A company representative did note that many more brackets are still in contention for the 20 first place prizes of $100,000.
These are given out to people who, despite not having perfect brackets, have the most accurate brackets.
The second round of March Madness wraps up on Friday night and the third round will take place over the weekend.
After that, there will be 16 teams remaining.
