Kalshi will pay you $1B to get all 63 March Madness games right

• Kalshi is offering a $1 billion prize to anyone who predicts every March Madness game correctly, yes, all 63 of them
• Even if perfection is nearly impossible, the highest-scoring participant still takes home $1 million, plus charitable donations
• The challenge has strict rules, a tight submission deadline, and participation limits, so speed and accuracy are key

Ever wondered how to get rich fast and just so happen to have a soft spot for college basketball? Well, Kalshi is happy to pay you $1bn if you correctly predictall of the 63 NCAA Tournament games.

Kalshi’s March Madness bracket challenge offers a $1 billion prize payout to one successful player

The prediction market platform has launched its customary bracket challenge for March Madness 2026, challenging players to put their knowledge of the event to good use.

In order to make the cut for the billion-worth bracket challenge, participants would have to meet several non-negotiable prerequisites. They must be at least 18 years old and US residents, as well as hold a Kalshi account.

Predictions must be submitted before March 19, 2026, with a deadline set for 1 pm ET or before tip-off of the first First Round game (whichever is first). Each participant may only place their selections once, and there cannot be more than 10 million entries in total, meaning that speed is of the essence.

Kalshi does realize that getting 63 perfect predictions is incredibly hard, and therefore the company will offer $1 million anyway to the highest scoring player, i.e., whoever got the most right games, with $1 million to be donated to charity and scholarships.

While the prospect of a $1bn payout sounds incredibly tempting, the odds paint a different story - you have a 1 in 9.2 quintillion chance of actually getting these right, making it incredibly unlikely.

No one has ever gotten all March Madness games predicted correctly

In fact, this is such an odd event that there has never been a public record of someone getting these predictions right - as part of an official contest, at least. Kalshi has also set out other important rules for would-be participants to follow.

Residents of New York and Florida, or currently based outside of the United States, may not participate. Employees and affiliated parties may also not participate in the competitions.

There is no requirement to make deposits in order to enter, nor is there a previous history of placing trades. While the billion-dollar prize is probably out of reach, someone will certainly win the $1 million prize instead.
