Prediction Markets Market: Record $5.7B World Cup Bets on Polymarket and Kalshi
Spain won the 2026 FIFA World Cup, concluding a record-breaking betting event on prediction markets Polymarket and Kalshi. Over $5.69 billion was wagered on the final alone. Combined monthly trading volume on the platforms surpassed $50 billion in June 2026, up from about $2 billion a year earlier, with app downloads and users surging dramatically. Both platforms invested heavily in marketing, including Kalshi's official FIFA partnership via ADI Predictstreet. However, regulatory backlash has intensified: more than a dozen US states have filed lawsuits, and European countries like Spain, Portugal, and Hungary have blocked access. Meta is reportedly developing its own prediction market app, while traditional betting firms and crypto exchanges are entering the space. Valuations stand at ~$22 billion for Kalshi and ~$15 billion for Polymarket. The article highlights the unresolved legal question of whether prediction markets are financial derivatives or unlicensed gambling.
Prediction markets are not core AdTech, but the article highlights their growth and regulatory challenges, which could impact digital media and advertising if they become more mainstream.
