Prediction Markets Hit Record $10.8 Billion Weekly Volume as SpaceX IPO, World Cup Drive Surge

According to A16z crypto, prediction market weekly trading volume reached a record $10.8 billion in the week ending June 15, 2026, marking the first time weekly activity exceeded $10 billion. The surge was driven by major concurrent events including the SpaceX IPO at a $2.1 trillion valuation, a U.S.-Iran peace deal, the NBA Finals, the Stanley Cup Final, and the opening stages of the World Cup.

The milestone reflects sustained growth across the industry. Baseline weekly volume has risen from approximately $500 million a year earlier to the $6 billion-$7 billion range this spring, with Kalshi and Polymarket accounting for the largest portions of the record week's activity.
