A Polymarket trader turned $676 into $67,574 after a UFC result was announced incorrectly and then corrected, according to an X post by Verrissimus. The post said Bruce Buffer initially read Marcin Tybura as the winner before the decision was revised in favor of Tyrell Fortune.
Hit my first 100x on Polymarket!
$670 → $67,000
but here's the crazy part: I almost bought Tybura at 99¢ with $100k. stopped, realized something was off.
cancelled my order, scooped up 1c shares instead. the UFC corrected the winner seconds later. easiest 100x ever https://t.co/vBO9eEA3pU pic.twitter.com/OM2XWVXfzI

According to the post, the error briefly pushed the market to 99¢ for the wrong side. The trader then bought 67,608 Tyrell Fortune shares at 1¢ before the UFC called Fortune back into the octagon, apologized and corrected the result to a unanimous-decision win, triggering a sharp repricing.
The next point to watch is whether the episode draws any further comment from traders or from Polymarket’s market observers. For now, the documented sequence shows how a live announcement error can create a short-lived arbitrage window in an event market.
