BlockBeats News, July 12th. Data from the prediction market platform Predict.fun shows that during the 2026 World Cup in the United States, Canada, and Mexico, a top sports high-frequency trader named swisstony emerged. Since entering the market in July 2025, this whale has made a total profit of $18.648 million, with a single largest profit of $1.2 million. The number of predictions has reached as high as 139,304 times, and the profit curve has been steadily rising.

His World Cup prediction record is outstanding, excelling at reverse operations when popular odds are overvalued, relying on high-frequency small-scale edge trading to accumulate huge profits. Although the average profit per transaction is small, the win rate is stable, and the cumulative effect is extremely strong. In June, this whale made a profit of approximately $9.5 million by contrarian predictions on popular teams (England, Spain, Belgium), briefly becoming the platform's fifth-largest profitable user.

swisstony is currently focusing on the France vs. Spain match on July 14th local time, heavily investing in multiple submarkets of this match. The main strategy is still to make a large number of "No" predictions, especially on low-probability precise scores, combined with some handicaps and over/under bets. The whale swisstony often ranks high on the monthly profit list in the prediction market, with daily profits exceeding $2 million at times. Analysis suggests that this whale may be using automated tools or real-time data assistance.
