Brendan Allen's emphatic fifth-round submission win over Christian Leroy Duncan on October 10 has extended his winning streak to four, positioning the No. 4-ranked middleweight for a high-profile 2027 return after he confirmed plans to sit out the remainder of 2026. His repeated post-fight callout of former champion Dricus Du Plessis, citing past differences and unfinished business, has elevated that matchup to the leading implied probability at 19.5 percent. However, the market remains tightly contested across multiple outcomes because the UFC middleweight division features several viable contenders with strong recent form, uncertain title paths, and no confirmed booking. Traders appear to weigh Allen's preference for meaningful fights against the promotion's scheduling flexibility and Du Plessis's own potential obligations, leaving room for alternatives like Caio Borralho or Joe Pyfer to gain traction depending on official announcements.
