During the World Cup, high-frequency sports prediction whale swisstony emerged, with its account notching up over 139,000 predictions and generating nearly $20 million in profits.

Data from prediction market platform Predict.fun shows that top high-frequency sports trader swisstony emerged during the 2026 FIFA World Cup (co-hosted by the U.S., Canada, and Mexico). Since entering the market in July 2025, the whale has generated total profits of $18.648 million, with a single largest profit of $1.2 million, having made a total of 139,304 predictions, and its profit curve has been steadily rising. Its World Cup prediction record is impressive: it excels in contrarian trades when popular odds are overvalued, amassing huge profits through high-frequency, small-margin trades. While average per-trade gains are modest, its stable win rate leads to strong cumulative returns. In June, the whale earned around $9.5 million by contrarian betting on popular teams including England, Spain, and Belgium, briefly becoming the platform’s 5th highest-earning user. Currently, swisstony is focusing on the France vs Spain match on July 14 (local time), placing heavy positions across multiple sub-markets for the game. Its core strategy remains making large volumes of "No" predictions—especially for low-probability exact scores—paired with some handicap and over/under bets. The whale consistently ranks at the top of prediction market monthly profit leaderboards, with a single-day profit exceeding $2 million. Analysts believe swisstony likely uses automated tools or real-time data to assist its trading.
