A Polymarket account under the handle LEEEROYJENKINS netted roughly $5.2 million in profit from a single World Cup group-stage match between Türkiye and Australia, splitting the position between a Türkiye-does-not-win contract and Australia +1.5 on the spread.
Why it matters
The combined position cost about $4.73 million to enter, making it one of the larger single-event sports wagers recorded on a crypto-native prediction market. That size, on a group-stage football fixture rather than a final, hints at how much liquidity Polymarket is now absorbing from bettors who would previously have routed through offshore sportsbooks.
Market impact
Sports markets have been the fastest-growing vertical on Polymarket through 2026, with World Cup fixtures drawing the bulk of new notional volume. A $4.73M-to-$9.93M trade, paid out cleanly, reinforces the venue's reputation for settling large positions without the friction that scares institutional-sized flow away from prediction markets.
