A recent incident during a UFC event showcased the volatility of prediction markets, as a trader achieved a remarkable return on investment following an announcement error. In a heavyweight bout held on Sunday, Tyrell Fortune secured his first victory in the UFC against Marcin Tybura, but the outcome was initially misreported by cage announcer Bruce Buffer.
Buffer mistakenly declared Tybura the winner, a statement that lasted for less than a minute before being corrected. This brief period of misinformation allowed a trader known as LlamaEnjoyer, or Verrissimus on social media platform X, to make a strategic investment that yielded nearly a 100-fold return.
Upon the erroneous announcement, shares for Tybura soared to approximately 99 cents, while Fortune’s shares plummeted to around 1 cent. LlamaEnjoyer initially considered placing a $100,000 bet on Tybura at the inflated price but opted against it after sensing a discrepancy. Instead, the trader purchased $676 worth of shares in Fortune at the lower price. Moments later, when the UFC rectified the announcement, Fortune’s shares surged to $1.
“I almost bought Tybura at 99¢ with $100k. Stopped, realized something was off. Cancelled my order, scooped up 1¢ shares instead. The UFC corrected the winner seconds later. Easiest 100x ever,” Verrissimus commented on X.
This incident underscores the rapid fluctuations that can occur in prediction markets, particularly during live events where announcements may be miscommunicated. It also raises important questions regarding the handling of payouts when errors arise from the primary source of information. Since the miscommunication originated from the UFC announcer, there may be potential disputes over the resolution of contracts, despite the legitimacy of the trader’s actions.
