Soccer prediction markets led the increase, with daily volumes quadrupling after the tournament began as World Cup trading activity accelerated on the platform.
Polymarket's sports trading activity has surged since the World Cup began, with daily volume rising from under $130 million to nearly $300 million. Soccer markets drove much of that increase, posting a fourfold jump in daily volume after the tournament kicked off. The move points to how major global sporting events can sharply increase activity in prediction markets (platforms where users trade on event outcomes), especially when liquidity concentrates around widely followed matches and tournament outcomes.
