During the World Cup, high-frequency sports “whales” in the sports sector—swisstony—have risen sharply, with the account making over 139,000 profitable predictions and totaling nearly $20 million in potential gains.

ME News message: On July 12 (UTC+8), data from the prediction market platform Predict.fun shows that during the 2026 World Cup spanning the US, Canada, and Mexico, top high-frequency traders emerged in the sports sector, including swisstony. Since this whale entered the market in July 2025, it has generated total profits of 18.648 million USD, with the largest single-trade profit reaching 1.2 million USD. The number of predictions reached 139,304 times, and its profit curve has continued to rise steadily. Its World Cup prediction record is impressive: it is skilled at taking the opposite side when popular odds are overestimated, relying on high-frequency, small-margin trades to accumulate enormous profits. Although its profit per trade is relatively small, its win rate is stable and its cumulative effect is extremely strong. In June, the whale reportedly profited about 9.5 million USD by counter-trend predicting popular teams (England, Spain, Belgium, etc.), at one point becoming the platform’s 5th-largest profit user.

swisstony is currently focusing on the France vs Spain match on July 14 local time. In that game, it has heavy positions across multiple sub-markets; its main strategy is still making large numbers of predictions of “No,” especially for low-probability exact score outcomes, together with some handicap lines and over/under lines. The whale swisstony often ranks near the top of the prediction markets’ monthly profit leaderboard, and on some days its profit has exceeded 2 million USD. Analysts believe this whale may be using automated tools or real-time data assistance. (Source: BlockBeats)
