Conor McGregor's return opponent became crystal clear as Max Holloway surged from 58¢ to 84¢ following the official UFC announcement that McGregor will make his long-awaited UFC return in a rematch against Max Holloway at UFC 329 on July 11. The massive volume of 753.74 reflects genuine conviction rather than speculation — UFC 329: McGregor vs. Holloway 2 is scheduled to take place on July 11, 2026, at the T-Mobile Arena with a welterweight bout between the former champions headlining the event. This marks McGregor's first fight in five years, as he last competed in July 2021 when he suffered a gruesome leg injury against Dustin Poirier. The 26-cent jump represents traders pricing in what's essentially a done deal, with the market now implying an 84% probability of this long-awaited rematch.
