How a UFC Announcer’s Slip Turned $676 Into $67,000 on a Prediction Market
In the fast-paced world of crypto-based prediction markets, a single moment of human error can create life-changing opportunities for alert traders. This was vividly demonstrated last Saturday during a UFC heavyweight bout, when a Polymarket speculator executed a near-perfect trade, transforming a modest $676 wager into a staggering $67,608 payout—all within seconds.
The incident occurred during the fight between Tyrell Fortune and Marcin Tybura. As the judges’ scores were read, UFC presenter Bruce Buffer announced Tybura as the winner via unanimous decision. However, many viewers, including the trader known as LlamaEnjoyer on Polymarket (and Verrissimus on X), immediately sensed an error based on the fight’s apparent flow and the scorecards being displayed.
On Polymarket, shares for “Tyrell Fortune Wins” plummeted to one cent following the initial, incorrect announcement. Recognizing the likely mistake, LlamaEnjoyer swiftly purchased those distressed shares. Moments later, Buffer corrected himself, officially declaring Fortune the winner. The market price for Fortune’s shares instantly rebounded to 100 cents, cashing out LlamaEnjoyer’s position for a profit of approximately $67,000—a return of nearly 100 times his initial stake.
The Near-Miss That Almost Cost $100,000
The trader later revealed the critical split-second decision that made the trade possible. He had initially intended to place a much larger, $100,000 bet on Tybura at 99 cents—a seemingly safe move after the erroneous announcement. However, a gut feeling that “something was off” prompted him to cancel that large order at the last moment.
“Cancelled my order, scooped up 1c shares instead. the UFC corrected the winner seconds later. easiest 100x ever,” LlamaEnjoyer recounted. He placed his winning bet within an estimated 50-second window after Buffer’s initial mistake, before a UFC commentator even stated, “We have a mistake.” His quick skepticism, based on the live scorecards showing 29-28, 29-28, 30-27 in Fortune’s favor, proved immensely profitable.

“There’s no way Tybura won that fight,” LlamaEnjoyer stated, underscoring how real-time visual information can create fleeting arbitrage opportunities in prediction markets that react instantly to news.
Prediction Markets: A Rapidly Growing Frontier

The LlamaEnjoyer trade serves as a case study in the high-stakes, real-time nature of this sector. It demonstrates how a combination of attentiveness, decisiveness, and access to live information can capitalize on temporary market dislocations caused by human error. For traders, it’s a reminder that in prediction markets, the line between a catastrophic loss and a monumental win can be measured in seconds.
