**Record presales exceeding $65 million domestically and $125 million worldwide, months ahead of the December 18 release, anchor trader sentiment for Avengers: Doomsday's domestic opening weekend.** The Russo brothers' return with Robert Downey Jr. as Doctor Doom, alongside a massive ensemble reuniting Avengers, Fantastic Four, and X-Men elements, has fueled early demand that outpaces most comparables, including recent Marvel hits. Conservative trackers project $260-300 million while aggressive forecasts eye $400 million-plus, aligning with the market's 42.5% probability on the top bin and 30.5% on the next. Competition from Dune 3 the same weekend introduces audience split risk, yet Doomsday's outsized presales momentum and ongoing global marketing push—including new posters and a promotional tour—support the current frontrunner positioning for a potential record or near-record debut.
