Prediction market odds, tracked by event.

The 2026 FIFA World Cup has consumed prediction markets to a degree that should concern anyone tracking real money allocation. South Korea and USA World Cup contracts alone account for $199.5 billion in combined volume, nearly 68% of all activity across Kalshi and Polymarket. For context, the entire political category-including presidential races-represents just 43 markets and a fraction of that traffic.

This concentration reveals something worth examining: either prediction markets have become primarily sports wagering platforms, or serious money is fleeing traditional sportsbooks for blockchain-based alternatives. The economics suggest the latter. Crypto-native traders appear willing to accept regulatory ambiguity and platform risk for the transparency and speed these markets offer.

The political markets beneath tell a quieter story. James Talarico and Eric Trump nomination contracts trade at penny levels with relatively modest volume. These are not fringe bets; they're genuine political predictions from serious traders. Yet they're drowning in football noise.

What matters here is venue fragmentation. When this much capital concentrates on a single event, you're looking at either genuine consensus or illiquidity in alternatives. Neither interpretation suggests a healthy prediction market ecosystem.
