Polymarket trader nets $5M profit on Spain World Cup draw

A mystery trader on the Polymarket prediction platform turned approximately $4 million into $9 million by betting against Spain in their surprising World Cup draw against Cabo Verde. This anomaly trade, executed by a new wallet, has sparked speculation about whether it was pure luck or involved inside information. The bet involved Spain not winning outright and Cabo Verde staying within a 2.5-goal spread. Another trader lost nearly $1 million backing the favored Spanish team, highlighting the significant risks and potential rewards on the platform. Polymarket, which settles trades in USDC, has seen substantial activity during the World Cup.
