How to Enter Kalshi’s Billion Dollar Bracket Challenge
The biggest bracket prize in history is officially live. With the field set and the clock ticking, you have until Thursday morning to submit your picks for a shot at a ten-figure payout.
Here is the breakdown of the Kalshi $1 Billion Bracket Challenge and how the prediction markets are shaping the 2026 field.
The Stakes: B Is For Billion
Kalshi is swinging for the fences with a jackpot backed by SIG Parametrics.
The Perfect Bracket: $1,000,000,000. Yes, nine zeros. Nail all 63 games, and you change the world.
The “Leaderboard” Prize: If no one stays perfect, the person with the highest overall score still walks away with $1 Million.
The Giveback: Kalshi will also donate $1 Million to a charity of the winner’s choice.

How to Enter (It’s Free)
The best part? It’s free-to-play. You don’t need to trade or deposit to submit a bracket, but you must follow these steps:
Account & KYC: Create an account and pass identity verification (KYC) immediately. Don’t wait, verification surges can cause delays on Wednesday night.
Eligibility: You must be 18+.
State Restrictions: While trading is legal in most states, this specific $1B contest excludes residents of New York and Florida. (Residents there can still trade individual game contracts on the exchange, just not the bracket).
One Entry: Strictly one bracket per person.
CLEATZ Strategy: Follow the Money
According to the latest Kalshi prediction markets, traders are putting their money where their mouth is for the First Round:
The “Locks”: Duke (99%), Arizona (99%), and Houston (98%) are the market’s safest bets. Duke’s matchup against Siena alone has cleared $1.4M in trading volume, showing absolute conviction in the Blue Devils.
👀The Upset Watch: Keep an eye on the SMU vs. Miami (OH) market. At 72% odds, SMU is favored, but the 28% “Yes” price on Miami (OH) suggests this is where the early-round volatility lives.
⏰ The Deadline
Brackets Lock: Thursday morning, March 19, before the first game tips off.
Pro Tip: Get your verification done today. If the servers lag on Wednesday or Thursday, you don’t want to be left outside the billion-dollar gates.
