You can win 1 billion dollars by submitting a PERFECT March Madness bracket with Kalshi. And it’s FREE to enter.

All brackets must be submitted before tip off of the first game of the tournament on March 19th, 2026 or 1pm EDT of March 19th, 2026, whichever is earlier.

Your chances? Not great, if every game was a random 50/50, the odds of a perfect bracket would be a 1 in 9.2 quintillion.

No one has ever submitted a verified perfect bracket.

But it’s not impossible.

Winner picks are not random. Fans use statistics, logic, and basketball knowledge to make informed picks. With a hit rate of ~67%, the odds are about 1 in 120 billion.

And even if you aren’t perfect, the top winning bracket on Kalshi will win 1 million dollars. And they’re also donating 1 million dollars to charity and math scholarships.

So go. Be the one to make history at Kalshi and submit your entry before tip-off tomorrow.
