Prediction markets continue to demonstrate their incredible volatility, and the story of a user under the nickname DEEDDIT on the Polymarket platform is the best confirmation of this. This trader made perhaps one of the most impressive turnarounds in recent times, turning a catastrophic loss into a net profit of $10.7 million in just seven days. And notably, all of his successful trades were placed exclusively on football matches.
An analysis of DEEDDIT's profile shows that his largest single win was $6.1 million. A total of 17 predictions were recorded, but the decisive factor was a massive bet on the outcome of the match between the national teams of France and Spain. With a total trading volume on this market of about $4.9 million, the player took a payout of nearly $11 million. The net income from this single trade amounted to approximately $6.1 million, equivalent to a return of 124.83%.
What the turnaround looked like
On the overall chart for the entire existence of the account, it can be seen that the user went into the red by approximately $10.8 million. Meanwhile, on a narrow weekly slice, one can track in detail how the account dropped on the night of July 12, 2026. Immediately after this difficult period, the chart line shoots vertically upward — such a rapid recovery was ensured by a series of accurate sports bets.
In addition to the profitable position on France advancing, the list of completed contracts includes other extremely successful predictions. For example, the "No" option on France's victory on July 14, 2026, brought the wallet owner about $10.2 million with a turnover of $6.4 million. The net profit here was $3.8 million, or 59.45%.
The "Yes" option on a draw in regular time of the Switzerland vs. Colombia match yielded a payout of $5.7 million with investments of $1.9 million. Thus, the net income reached $3.8 million with a record return of 196.02%. Predictions on the advancement of the pairs USA vs. Belgium and Switzerland vs. Colombia to the next round, as well as the Asian handicap Spread: Spain (-1.5), also performed excellently.
Expert comment: Stories like these are a vivid illustration that prediction markets, especially in the sports niche, are becoming a full-fledged tool for professional trading. The ability to manage risks and make accurate bets based on deep analysis can yield results comparable to the best traders in traditional financial markets. However, it is worth remembering that the flip side of such profitability is enormous risk, and such comebacks are more the exception than the rule.
