"" Prediction Market Landscape Shifts Post-World Cup
The prediction market boom that accompanied the 2026 FIFA World Cup has come to an end, with global search interest in the category dropping back to pre-tournament levels. Combined weekly trading volumes on Kalshi and Polymarket have fallen below $10B for the first time since June, signaling a contraction in the market.
Kalshi's Dominance
Kalshi, the CFTC-regulated exchange, has emerged as the clear leader in the prediction market space, capturing approximately 83% of notional trading volume among approved US platforms during June and July 2026. This dominance is expected to be difficult for competitors to dislodge, given Kalshi's regulatory advantage and aggressive expansion into new contract offerings.
Market Share and Regulatory Advantage
Kalshi's market share during the World Cup, hovering between 80% and 90% of CFTC-approved platform volume, suggests that when prediction markets go mainstream, they do so through traditional financial rails. Polymarket, on the other hand, has historically drawn a more crypto-native audience and has found success in niche crypto events and geopolitical outcomes.
Future Directions
As the prediction market landscape continues to evolve, it will be interesting to see how Kalshi and Polymarket adapt to changing market conditions. Kalshi's expansion into new contract offerings, such as weather events and economic data releases, may help the platform maintain its market share. Meanwhile, Polymarket's permissionless listing model will likely continue to attract traders looking for alternative markets.
