Key points:

• A trader on Polymarket transformed approximately $676 into $67,000 in less than a minute after UFC announcer Bruce Buffer mistakenly announced the wrong winner of a heavyweight fight.
• This incident highlights the swift volatility of prediction market pricing due to errors during live events and prompts discussions on how platforms ought to manage payouts when the official source of information is incorrect.

A trader achieved nearly a 100x return on the decentralized betting platform Polymarket within a minute, attributed to a mistake made by a UFC announcer.

In Sunday’s UFC heavyweight fight, Tyrell Fortune claimed victory over Marcin Tybura for his first win in the UFC. However, the event was marked by controversy. Announcer Bruce Buffer initially declared Tybura the winner, a statement that lasted less than a minute before Buffer rectified the error.

LlamaEnjoyer, a trader on Polymarket, also known as Verrissimus on X, seized the opportunity from the mistake, turning about $676 into $67,000.

When Tybura was proclaimed the winner, shares for him surged to nearly 99 cents while Fortune’s shares plummeted to around 1 cent. LlamaEnjoyer recounted that they nearly placed a $100,000 wager on Tybura at 99 cents but halted upon sensing something was off. Instead, the trader opted to purchase $676 worth of Fortune shares at 1 cent. Moments later, after the UFC corrected the announcement, the shares instantly rose to $1.

“I almost bought Tybura at 99¢ with $100k. Stopped, realized something was off. Canceled my order, scooped up 1¢ shares instead. The UFC corrected the winner seconds later. Easiest 100x ever,” Verrissimus stated on X.

LlamaEnjoyer’s prompt action illustrates how rapidly prediction market prices can fluctuate during live events, particularly when significant announcements are misinterpreted or inaccurately reported.

The event also prompts inquiries regarding the management of payouts when there is an error at the “source of truth” — the reference point contracts depend on for outcome determination. As the mistake originated from the UFC announcer, there may be potential disputes over payouts or contract resolutions, despite the trader’s actions being entirely legitimate.
