What is PredictMarketCap?

PredictMarketCap is a prediction market data aggregator that compares real-time odds across Polymarket and Kalshi. It ranks markets by volume, shows cross-platform price spreads, and helps you find where platforms disagree on the same event.

How do prediction markets work?

Prediction markets let traders buy and sell shares tied to real-world outcomes. Each share pays out $1 if the event happens. If a share trades at $0.60, the market is pricing a 60% probability. Prices move as traders buy and sell based on new information.

What is the difference between Polymarket and Kalshi?

Polymarket is a crypto-native prediction market that trades in USDC on the Polygon blockchain. Kalshi is a CFTC-regulated exchange that accepts US bank deposits and is legal for US residents. PredictMarketCap compares odds across both platforms so you can see where they agree and disagree.

What is prediction market arbitrage?

Arbitrage occurs when the same event has different prices on different platforms. For example, if Polymarket prices an outcome at 60% but Kalshi prices it at 55%, traders can potentially profit from the spread. PredictMarketCap highlights these cross-platform price differences.
