Summary
Kalshi's July trading volume surged 14% month-over-month to $37.7 billion, driving the combined prediction market volume with Polymarket to an all-time high of $50.59 billion. The World Cup provided a major boost, with $1.9 billion bet on the final match alone. While Kalshi gained share, Polymarket's offshore volume contracted 26%, though its U.S. platform grew 54% after removing waitlist restrictions. Open interest has since halved to $1.2 billion, signaling a post-tournament cooldown. This follows June's record $31.5 billion for Kalshi and ongoing legal battles with state regulators over sports contracts.
