A crypto trader earned $8.47 million in a day on football predictions: analysis of Polymarket's success and risks
An anonymous user under the nickname blunttedge demonstrated an impressive result on the decentralized prediction platform Polymarket, earning $8.47 million in net profit in just one day by betting on FIFA World Cup matches.
This case caught my attention as an analyst because it clearly demonstrates both the potential and the extreme volatility of sports prediction markets in the DeFi environment. blunttedge's strategy was aggressive and high-risk: he created a new wallet and immediately began operating with large sums.
Details of the Winning Strategy
Two bets were key. The first was a $7.19 million bet on Sweden winning and Japan losing in a match that ended in a 1:1 draw. Despite the outcome not matching the prediction, the market mechanism allowed the trader to exit with a profit of $4.38 million. The second was a $2.26 million bet on Ecuador defeating Germany, which paid off: Ecuador won 2:1, bringing in $4.09 million.
The total turnover of funds was approximately $19 million, with a net profit of $8.47 million. This result instantly propelled blunttedge to the top of the platform's leaderboard with a figure of +$8,474,966.
The Flip Side of the Coin
However, as I often emphasize in my analysis, behind every loud success on Polymarket lie equally loud failures. A contrasting example is the recent disaster of user supersob, who lost nearly $5.8 million in 24 hours. His mistake lay in incorrect bets on Belgium and against Norway.
Analysis of supersob's account paints a grim picture: the final negative balance was $6.86 million with a total turnover of $16.73 million. His prediction accuracy (win rate) dropped to 25%. The most painful blow was the bet on Belgium, which resulted in a $3.12 million loss. Matches involving Norway and France added millions more to the losses. Before this fateful day, the user's peak profit had reached $4 million, but during the group stage, only three out of twelve major predictions turned out to be correct.
My expert conclusion: Prediction markets on decentralized platforms are not just gambling but a complex financial environment where large positions carry catastrophic risks. blunttedge's success is an exception, not the rule. The vast majority of traders, as the example of supersob shows, lose significant funds due to insufficient diversification and overestimating their analytical abilities. In this field, the winner is not the one who makes the boldest bets, but the one who knows how to manage risk.
