Profitable Polymarket accounts bet against Mexico in England World Cup clash
Several historically profitable Polymarket accounts placed bets that Mexico will not win in regulation against England in a World Cup Round of 16 match, the platform disclosed July 5.
For Polymarket, highlighting profitable addresses serves as implicit marketing: it signals that sophisticated traders find edge on the platform, which attracts retail copy-betting and deepens liquidity. The real-time USA-Belgium market, meanwhile, tests whether event contracts can match sportsbooks for in-play velocity without spread blowouts or settlement lag. The platform has not released per-market volume or open-interest figures, so traders cannot verify whether these markets absorb size or merely headline well. Clean settlement through the knockout round would bolster Polymarket's case that it can host sportsbook-scale events; any cracked trade or delayed resolution would feed the gambling-label arguments state attorneys general are already probing.
The World Cup has become the proving ground for whether prediction markets can handle sportsbook-scale liquidity, with profitable addresses testing settlement infrastructure under tournament pressure.
