A Polymarket trader converted $676 into roughly $67,608 by exploiting a rare announcing mistake during the UFC heavyweight bout between Tyrell Fortune and Marcin Tybura. The user, known on Polymarket as LlamaEnjoyer and on X as Verrissimus, noticed presenter Bruce Buffer briefly declare Tybura the winner, which caused shares backing Fortune to collapse to one cent.
LlamaEnjoyer said they canceled an almost $100,000 order on Tybura after sensing something was “off,” then used $676 to buy one-cent shares on Fortune. Seconds later Buffer corrected himself and declared Fortune the winner, producing near 100x returns and roughly $67,000 in profit for the trader.
The trade, the trader said, was executed within about 50 seconds of the incorrect announcement and before commentators announced, “We have a mistake.” LlamaEnjoyer called it the “easiest 100x ever.”
The episode underscores how quickly prices in live prediction markets can swing during unfolding events. Crypto-based prediction trading has expanded rapidly: trading volumes surpassed $10.4 billion in March — a tenfold increase from March 2025 — with more than 865,000 users placing bets that month across platforms including Polymarket, Kalshi and Opinion.
Industry moves have mirrored that growth. ICE’s parent company committed a new $600 million investment in Polymarket, reflecting both growing institutional interest and the scaling of these markets. The incident highlights the opportunity for rapid gains but also the speed-driven risks inherent in trading around live events.
