Multiple outlets report that the bout ends by TKO, with Topuria’s corner stopping the fight. The result crowns Gaethje as champion, with some sources framing it as an undisputed title win. Coverage from different outlets emphasizes the scale of the surprise, noting that many expected Topuria to win. Some reports also describe the finish as “No Mas” or “corner stop,” aligning on the key end-of-fight detail rather than a single referee decision.
