Luis Gurule scored a major upset over Bilal Hasan at UFC 334, taking a split decision at Madison Square Garden after oddsmakers and artificial intelligence had both backed Hasan. Hasan had been a -1000 favorite, and his main card placement in just his second UFC bout reflected the promotion's belief in him, with many considering him the most promising signee from this season's "Dana White's Contender Series."

The fight started as expected, with Hasan landing stiff strikes and kicks, including one to the head, while the elusive Gurule struggled to close the distance. Gurule then landed a counter right hand that scored a flash knockdown in the first round, though Hasan bounced back quickly. Hasan's volume was seen by many as enough to win that round.S1S2

Gurule, an NCAA Division II All-American who had landed at most one takedown per fight previously in the UFC, changed his approach in the second and third rounds by taking Hasan down and controlling him with wrestling and ground-and-pound. Hasan tried submissions from the bottom in the final round but could not escape, and he suffered a cut over the eye that Gurule opened with an inside elbow.S1S2

The judges scored the bout 29-28 and 29-28 for Gurule, with the third official scoring it 29-28 for Hasan, handing Hasan the first loss of his professional career. Gurule, celebrating afterward, said "ChatGPT don't know s**t" and that only 10 people had believed in him, adding that he had dragged Hasan into deep waters because "he couldn't swim."S1S2
