A Polymarket trader made $67,000 in a minute by capitalizing on a mistake

A trader on the crypto prediction market Polymarket capitalized on a mistake made by a commentator for the Ultimate Fighting Championship (UFC) and turned $676 into $67,000. In less than a minute, he made a hundredfold profit.

The UFC ring announcer incorrectly announced the winner of the fight between American Tyrell Forchun and Polish fighter Marcin Tybur at UFC Fight Night in Seattle. Forchun won, but the announcer called out Tybur.

The mistake was corrected within a minute. A Polymarket user who had predicted the outcome of the fight under the username LlamaEnjoyer, also known as Verrissimus on X, managed to take advantage of the moment. LlamaEnjoyer is an active Polymarket user who has participated in nearly 5,000 predictions.

When Tybur was announced as the winner, tokens for him on Polymarket jumped to 99 cents, while those for Fortune dropped to about 1 cent. LlamaEnjoyer realized a mistake had been made and bought $676 worth of tokens for Fortune at 1 cent each. A few seconds later, the UFC corrected the error, and those tokens immediately jumped to $1.

“But here’s the craziest part: I almost bought Tyburu tokens at 99 cents for $100,000. I stopped myself, realizing something had gone wrong. Instead, I bought shares at 1 cent. UFC corrected the winner within a few seconds. The easiest 100x win in history,” the trader wrote.

Over the past six months, prediction markets have become virtually the only sector of the crypto economy to show positive growth, with trading volume on such platforms rising from $400 million to $6 billion. Regulators in several countries classify these services as illegal gambling and ban them. In mid-March, Polymarket was blocked in Argentina.
