Polymarket's Champions League markets hit $260M volume alongside million-dollar Arsenal wagers
Polymarket has logged $260 million in Champions League trading volume as large bets rolled in ahead of the final, according to a May 30 Binance report. A single trader wagered $1,550,444 on Arsenal to win the tournament at a 47% implied probability, per a Polymarket Sports post on Saturday, May 30. Another account with over $3.8 million in historical profits invested $284,000 on Arsenal defeating Paris Saint-Germain, per Odaily. Separately, a trader placed $675,000 on Arsenal via Kalshi FC for a potential $1.5 million payout, the platform's X account posted Saturday. Polymarket also noted halftime odds shifts as Arsenal led during a match. Television personality Piers Morgan posted on X that he suspected a Polymarket Champions League market was mispriced, without naming specific odds or teams.
Polymarket must convert this event-contract volume into sustainable fee revenue before rival Kalshi's Interactive Brokers integration and hedge fund outreach lock in institutional market share. The platform still lacks CFTC registration, leaving its sports push exposed to any state gambling classification ruling that would empower Ohio, Pennsylvania, Wisconsin, or Minnesota regulators to force geofencing.
Tracks the platform's pivot from pure prediction markets toward sports-specific products and partnerships, extending a month-long pattern that includes the Yahoo Sports deal, multi-leg contracts, perpetuals, and now World Cup and Champions League verticals as it builds volume without CFTC registration.
