Prediction markets posted a new single-day trading record of $4.8 billion on June 12, coinciding with the start of World Cup group-stage matches, according to recent data.
Trading activity on the first day of the tournament, June 11, registered $2.2 billion. Volume then more than doubled the following day when the United States faced Paraguay, producing the record daily total cited above.
The volume tied to the World Cup has already exceeded amounts observed around the Super Bowl. Last season's Super Bowl generated $1.4 billion in trading volume for prediction markets, a level the tournament has now grown past while still in its early group stage phase.
Market leadership by volume currently sits with two platforms: Polymarket's U.S. operation and Kalshi. Both platforms are identified as the top venues for trading in the prediction-market space based on the reported activity.
These figures represent a snapshot taken at the outset of the World Cup group rounds. The tournament remains in its early phase, and the recorded daily totals reflect activity tied to the opening matches and the specific fixtures mentioned.
This report focuses on the trading volumes recorded during the first days of the World Cup and the comparison to a prior major sporting event. It does not attempt to attribute causes beyond the timing of matches or to project future volumes beyond the stated data.
Key numeric takeaways are plainly stated: $2.2 billion on June 11, a jump to $4.8 billion on June 12, and a point of comparison at $1.4 billion for the previous Super Bowl season. The named platforms leading by volume are Polymarket's U.S. platform and Kalshi.
The data presented here is limited to the trading volumes and the early tournament timeline; it does not extend to broader market or regulatory analysis, nor does it include additional performance metrics for specific platforms beyond reported volume rankings.
