Selection Sunday is here, and the Kalshi Billion Dollar Bracket gives college basketball fans a chance to turn March Madness into a life-changing payday. Submit a perfect NCAA Tournament bracket, and you could win $1 billion. Even if no one gets every game right, the highest-scoring bracket will still win $1 million, with another $1 million donated to charity.
Entering the bracket contest is simple. You only need to create and verify a Kalshi account and submit your picks before the tournament begins. There is no deposit or trade required just to enter the contest.
Billion Dollar Bracket
Kalshi Billion Dollar Bracket details
The Billion Dollar Bracket contest centers on the 2026 NCAA Men’s Basketball Tournament, with the bracket field announced on Selection Sunday, March 15, 2026. Once the teams are revealed, participants can build and submit their bracket directly on Kalshi’s platform.
To enter the contest, users must create an account, complete identity verification, and submit their bracket before tournament play begins. According to the contest details, entrants must be 18 or older, and only one bracket entry is allowed per person.
The headline prize is $1 billion for a perfect bracket, one of the largest promotions tied to March Madness. Even if no entrant achieves perfection — which is extremely likely — Kalshi guarantees $1 million to the best overall bracket.
The grand prize is insured by SIG Parametrics, adding credibility to the promotion and ensuring that the billion-dollar payout would be covered if someone beats the astronomical odds.

How hard is a perfect bracket?
Picking a perfect NCAA Tournament bracket is one of the toughest challenges in sports. The odds are widely estimated at roughly 1 in 120.2 billion if someone makes informed picks based on team strength and probabilities.
If every game were selected at random, the odds would balloon to approximately 1 in 9.2 quintillion.
That’s why the more realistic prize for most entrants is the $1 million awarded to the top-performing bracket. Still, March Madness is famous for its unpredictable upsets, which is exactly what makes bracket contests so exciting every year.
