FIFA World Cup Drives Record Prediction Market Activity

Much of the increase has been attributed to the 2026 FIFA World Cup, which began on June 11. This year's tournament is the first to feature 48 teams, expanding from the previous 32-team format. According to CNBC, the World Cup became the biggest catalyst for prediction market activity during June, with Dune Analytics reporting record notional trading volumes across both Kalshi and Polymarket.
Knockout matches generate millions in bets
As the tournament progresses into the knockout rounds, individual matches have attracted significant trading activity. Canada’s Round of 16 match against Morocco, scheduled for Saturday, generated more than $48 million in trading volume on Kalshi and over $26.8 million on Polymarket at the time of writing.
The United States’ Round of 16 fixture also attracted substantial interest. Kalshi’s market predicting which team would advance recorded more than $2.1 million in trading volume, while a similar market on Polymarket reached approximately $1.6 million. The growing popularity of sports-related prediction markets has helped drive overall platform activity to new highs.
Regulatory debate continues
The surge in trading comes as prediction markets remain the subject of increasing legal and regulatory scrutiny in the United States. By March, nearly a dozen US states had taken action against companies including Kalshi and Polymarket. Some sought to block their operations, while others argued the platforms should be regulated under existing gambling laws and state taxation frameworks.
Federal regulators have pushed back against those efforts. In April, Commodity Futures Trading Commission (CFTC) Chair Michael Selig argued that Congress had granted the agency exclusive authority over commodity derivatives markets, including prediction markets. “To any state that seeks to nullify federal law and seize authority over these markets,” Selig said, “we will see you in court.”
The debate has also expanded beyond regulators. In June, casino operators, tribal organizations and labor groups urged Congress to amend the Digital Asset Market Clarity (CLARITY) Act, arguing that sports-event contracts should remain under state gambling regulations rather than fall within the CFTC’s jurisdiction.
Europe has taken a different approach. On Friday, the European Securities and Markets Authority (ESMA) reminded firms that many event-based contracts may already fall under existing restrictions on binary options, emphasizing that regulatory treatment depends on a product’s characteristics rather than whether it is labeled as an "event contract."
