How Do These Prediction Platforms Work?

Polymarket and Kalshi are blockchain based prediction markets. You deposit stablecoins like USDC to buy shares on a sporting outcome. If your prediction is correct at the end of the match, each share is worth $1. Otherwise, it is worth $0. Smart contracts automatically settle winnings without any human intervention. The rules are hardcoded and cannot be modified along the way.

Buying a “PSG to win” share at $0.57 yields $1 in the event of a Parisian victory, representing a +75% net profit. You can also sell your position at any time before the final whistle if the probabilities shift in your favor. This is a major advantage over the fixed odds of traditional bookmakers. The real time liquidity allows you to arbitrage your positions based on breaking news, lineups, or injuries.

The difference between the two platforms is clear. Polymarket is crypto native: higher liquidity, lower fees, and 101 active markets for the final. Kalshi is regulated by the CFTC and accessible directly via credit card without a crypto wallet. It is the ideal option for beginners who do not want to manage cryptocurrencies directly. For European users, Polymarket remains the gold standard for market depth in football.
