That’s one very expensive game of football. Kalshi’s FIFA World Cup Winner market has officially surpassed $1 billion in trading volume, becoming the platform’s largest market by a wide margin.
For perspective, Kalshinomics CEO Aaron Brogan noted that the highest-volume non-sports market—the 2028 Democratic nominee contract—has traded about $143 million. The milestone underscores just how powerful global sporting events have become for regulated prediction markets, with traders piling into contracts more than a year before kickoff.
