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

The perfect March Madness bracket might still exist, but the chances have narrowed significantly after the first round of games wrapped up on Friday night. 

Of the more than 36 million brackets filled out across major sports platforms, only 224 flawless entries remained entering the second round on Saturday, according to the NCAA's website. 

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.

According to the NCAA, the biggest bracket buster of the day was No. 7 seed Kentucky's thrilling overtime victory over No. 10 seed Santa Clara. The Broncos looked primed to upset the Wildcats, but Otega Oweh's 3-pointer in front of his own bench with just 2.4 seconds in regulation gave Kentucky the path to score eight consecutive points in overtime to move on to the second round. 

Roughly 6,000 brackets were dismantled by the final whistle. Another 3,200 were busted when Utah State pulled away from Villanova, 86-76. 

NEARLY 36 MILLION MARCH MADNESS BRACKETS BUSTED ON DAY ONE AS UPSETS WREAK HAVOC

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. 

The NCAA predicts the biggest bracket buster will be Michigan State vs. Louisville. If Louisville wins, just 74 brackets will advance. 

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.
