Football Draw Harvests Whales: Extreme Profit-Loss Divergence on Polymarket's World Cup
A bettor known as "fishalive" made a stunning profit of nearly $9 million on the Polymarket prediction platform by correctly wagering against favorites during the 2026 FIFA World Cup group stage. The account, registered just before the tournament, risked roughly $400,000 on two contracts for a Spain vs. Cape Verde match: one that Spain would *not* win, and another on a Cape Verde +2.5 goal handicap. The resulting 0-0 draw triggered both payouts.
This single event, with a total market volume of $64 million, highlighted extreme profit-and-loss divergence. Other traders, like "betoor619" and "leeeeroyjenkins," lost millions by betting heavily on favorites Spain and Belgium to win outright—contracts that become worthless in a draw.
The article explains that while markets heavily favored strong teams, the "team to win" contracts are binary and do not account for the common outcome of a draw. This creates high-risk, low-reward scenarios for favorite backers, while asymmetric profits flow to those betting on underdogs or against outright wins. The transparency of Polymarket's on-chain ledger publicly documents these massive wins and losses, driving mainstream media coverage.
As the tournament progresses, the author suggests traders may shift towards hedging strategies that account for draws. The piece also notes growing regulatory scrutiny in the US and Europe, questioning whether such large-scale, anonymous sports prediction markets should be regulated as gambling or financial derivatives.
