🎯 Polymarket traders took advantage of a UFC broadcaster's mistake, turning $676 into $67,000 in 1 minute

According to reports from CoinDesk, Cointelegraph, and Coinspeaker today (March 30), a Polymarket trader seized the moment when the UFC announcer mispronounced the winner's name during a heavyweight fight, executing a nearly 100-fold trade.

📌 Incident details (confirmed):

1. The UFC announcer mispronounced the winner's name when announcing the fight results

2. The corresponding prediction market price on Polymarket collapsed instantly—contracts for the actual winner Tyrell Fortune dropped to 1 cent

3. Trader LlamaEnjoyer (known as Verrissimus on X) quickly bought 1 cent contracts for $676

4. The announcer promptly corrected the mistake, and the contract price returned to $1

5. Final profit: $67,608, with a return rate of about 100 times

🔍 What this reveals:

• Real-time pricing in prediction markets heavily relies on external information sources—a single broadcasting mistake can create a massive arbitrage opportunity

• Such "delayed arbitrage" is drawing the attention of regulatory authorities, especially in the sports prediction market sector

• Polymarket has previously faced controversy over bets related to the Iranian missile attack

💡 Opinion:

This is not "exploiting a loophole," but an extreme case of information asymmetry. The efficiency of prediction markets depends on the speed of information dissemination—when official sources make mistakes, the fastest responders reap excessive rewards. This is also a core challenge that decentralized prediction markets need to address.
