A Polymarket user known as LEEEROYJENKINS walked away with $5.2 million in profit after placing a pair of coordinated bets on yesterday's World Cup match between Türkiye and Australia.
The trader deployed $4.73 million across two positions: one betting that Türkiye would not win, and a second on Australia +1.5 in the spread market. Both bets resolved in his favour, generating a net profit of roughly $470,000 on a multi-million dollar stake — a modest percentage return that nonetheless represents one of the larger single-event payouts seen on the prediction market platform.
The trade highlights how Polymarket's liquidity has grown deep enough to absorb seven-figure positions on major sporting events, with a single user able to move that scale of capital without apparent slippage issues. For crypto-native prediction market watchers, it is a data point on how far on-chain betting infrastructure has matured.
