Prediction market platform Kalshi reported a 3 million user increase during the FIFA World Cup 2026. The platform recorded a 36% rise in daily visitors by the end of June.
Tournament Trading and Promotional Activity
Trading activity on the World Cup 2026 winner market exceeded $1.2 billion, establishing a new platform record for a single market. The user growth followed a coordinated promotional effort featuring former players and coaches Luka Modrić and José Mourinho. Kalshi also partnered with the Argentina national team and secured stadium co-branding through an agreement with ADI Predictstreet, the official prediction market sponsor of FIFA.
Post-Tournament Retention Strategy
Retaining the newly acquired audience remains the next operational priority. CEO Tarek Mansour noted that trading volume declined on days without scheduled matches. The company plans to direct platform resources toward upcoming large-scale events to maintain user engagement.
