Deep Tide TechFlow message, March 30, according to CoinDesk, on the decentralized prediction market platform Polymarket, a trader used a mistake in the UFC event broadcast to convert approximately $676 into approximately $67,000 within less than one minute, earning nearly a 100x profit.

In this UFC heavyweight bout, Tyrell Fortune defeated Marcin Tybura to win. However, the arena announcer, Bruce Buffer, initially misread the result and reported Tybura as the winner. As a result, on Polymarket, the share price of Tybura surged to as high as $0.99, while Fortune’s share fell to about $0.01.

After the false report, the trader LlamaEnjoyer (X account Verrissimus) noticed something unusual, abandoned the plan to buy $100,000 worth of Tybura shares at $0.99, and instead bought Fortune shares worth $676 at $0.01. A few seconds later, the UFC corrected the broadcast; the price of Fortune’s shares immediately rebounded to $1. The trader therefore profited about $67,000.
