If you want to invest in the NCAA Tournament, Kalshi provides a fully regulated prediction market.

These contracts fluctuate in value between 1 cent and 99 cents based on the market's implied probability. Once an event concludes, all winning shares settle and pay out at exactly $1 each.
By taking advantage of the Kalshi promo code WSN, you unlock their latest introductory offer. Simply create a new account, fund your wallet, and purchase your first 100 contracts on any market. Once those positions are executed, the platform will credit your account with a $10 reward to expand your trading portfolio.
