March Madness perfect bracket count drops to just over 200 out of 36 million after opening round

Roughly 14,000 brackets remained after a trio of upsets on Thursday, and despite no Cinderella stories on Friday, that number was further reduced to 224. That number dropped further on Saturday afternoon after No. 1 seed Michigan punched its ticket to the Sweet 16, leaving just 207 entries intact.

Saturday could see more heartbreak for fans (or optimism) with three upset winners scheduled to play top seeds. No. 11 Texas will take on No. 3 Gonzaga at 7:10 p.m. ET, No. 11 VCU will face off against No. 3 Illinois at 7:50 p.m. ET, and No. 12 High Point will battle No. 4 Arkansas at 9:45 p.m. ET. 

A perfect bracket for all 63 games earns more than just bragging rights.

Kalshi, a leader in prediction markets - in which users buy and trade shares based on potential event outcomes - is offering $1 billion to anyone who predicts all 63 tournament games correctly, with a "consolation" prize of $1 million to the person who finishes with the top-scoring bracket.

According to its tracker, only two entries remain perfect on Kalshi's platform.
