Prediction Market Volumes Surge to $44.8B in June Amid World Cup Monitoring

June prediction market volume hits record $44.8B. World Cup monitoring issued 7 yellow warnings, though FIFA found no suspicious betting activity across 104 matches.

Woofun AI reports that prediction markets achieved a record monthly trading volume of $44.8 billion in June, with Kalshi and Polymarket processing nearly $2 billion in transactions related to the World Cup final. This tournament marked the first instance of continuous prediction market monitoring, during which the European Council's Copenhagen Group issued seven yellow warnings and placed 15 matches under enhanced surveillance. These lowest-tier alerts indicate abnormal odds fluctuations or unverified social media rumors but do not constitute evidence of match-fixing. FIFA officially confirmed on July 21 that no suspicious betting activities were detected across all 104 matches of the 2026 World Cup.
