Polymarket logs $32M in single-match World Cup volume on Norway-Senegal
Polymarket recorded more than $32 million in trading volume on a single World Cup group stage match between Norway and Senegal, which Norway won 3-2. The figure follows Polymarket's soccer-category trading volume exceeding $2 billion in the 10 days before the World Cup, up 300% from the prior 10-day period, according to a separate report. Kalshi also benefited from the tournament-driven activity, with its aggregated open interest reaching a record $1.16 billion last week, the first time the platform's OI surpassed the billion-dollar mark. The milestones come as prediction markets broadly ride the World Cup wave.
Single-match volume of this size proves Polymarket's soccer markets can absorb institutional-size positions during live events, not just in long-dated futures. That liquidity edge pressures Kalshi and Robinhood's Rothera test to match execution depth tournament-wide, not just on headline outrights.
