$676 made a profit of $67,000! The prediction market for UFC matches "misjudgment arbitrage" sparks heated discussions again.

Gate News reports that an active trader in the prediction markets seized an instant opportunity arising from a commentary mistake during a UFC match, achieving nearly a hundredfold profit and sparking widespread discussion about real-time odds mechanisms. The trader rapidly amplified $676 to approximately $67,608 by leveraging a brief information deviation during the live broadcast.

The incident occurred during the heavyweight clash between Tyrell Fortune and Marcin Tybura. After the match, host Bruce Buffer mistakenly announced Tybura as the winner, causing the related prediction contract prices to plummet to 1 cent. Trader LlamaEnjoyer recognized the anomaly and decisively bought in before the official correction, locking in substantial profits within seconds.

According to him, he had initially prepared to place a large bet on the incorrect outcome at nearly $1 but canceled the order upon noticing the anomaly and instead positioned himself at lower prices. Shortly after, the UFC swiftly corrected the result, confirming Fortune as the winner, and the trade subsequently yielded nearly a 100-fold return. The entire process took place in about 50 seconds, illustrating the time lag between information dissemination and market reaction.

This case highlights the high volatility characteristics of prediction markets during live events. Since prices are entirely dependent on real-time information flow, any misreporting or delay can create brief arbitrage windows. For high-frequency participants, the ability to judge information and execute trades rapidly becomes a critical variable.

Data shows that the trading volume in prediction markets surpassed $10.4 billion in March 2026, a substantial increase compared to the same period last year. Over 860,000 users are now participating across platforms including Polymarket and Kalshi, covering various fields such as sports, politics, and macroeconomics. As the market size expands, such “information arbitrage” phenomena may become more frequent, raising higher demands on platforms’ data accuracy and risk control mechanisms.
