A trader made a nearly 100x return on decentralized betting platform Polymarket in less than a minute, thanks to a mistake made by a UFC announcer.
In Sunday’s UFC heavyweight fight, Tyrell Fortune defeated Marcin Tybura to secure his first UFC victory. But the event was not without drama. Cage’s announcer, Bruce Buffer, initially read the result in Tybura’s favor, a result that held for less than a minute before Buffer corrected the error.

When Tybura was named the victor, his shares soared to 99 cents and Fortune’s collapsed to about 1 cent. Llama Enjoyer said they almost made a $100,000 bet on Tybura at 99 cents, but stopped when they realized something was wrong. Instead, the trader bought $676 worth of Fortune shares at 1 cent. Seconds later when the UFC corrected the ad and the stock immediately jumped to $1.
“I almost bought Tybura at 99¢ with $100,000. I stopped it, realized something was wrong. I canceled my order, got 1¢ stock instead. The UFC corrected the winner seconds later. It’s 100x easier than ever,” Verrissimus said on X.
Llama Enjoyer’s quick thinking illustrates how quickly prediction market prices can swing during live events, especially when important announcements are misinterpreted or reported.
The incident also raises questions about how payments are handled when there is an error in the “source of truth,” the reference on which contracts are based to resolve outcomes. Since the error originated from the UFC announcer, there could be a dispute over payments or termination of the contract, even though the merchant’s actions remain completely legitimate.
