‘Dune 3’ Is Already Being Written Off in Its Box Office Showdown With ‘Avengers: Doomsday’
December 2026 was always shaping up to be one of the most stacked months in recent movie history, but nobody expected the drama to start months before either film even hits theaters. ‘Dune: Part Three’ and ‘Avengers: Doomsday’ are barreling toward the exact same release date, and the internet has already given the collision a name.
Fans and trade insiders have taken to calling the head-to-head event “Dunesday,” a nod to the 2023 ‘Barbenheimer’ phenomenon that turned a scheduling coincidence into a cultural moment. Warner Bros. and Legendary’s ‘Dune: Part Three’ and Disney and Marvel’s ‘Avengers: Doomsday’ have officially claimed the same release date for months, and theater owners have grown increasingly nervous about the two films cannibalizing each other’s audiences. Denis Villeneuve’s trilogy closer was actually first to stake its claim on the date, but that head start hasn’t done much to shift the conversation.
That brings us to what Pop Base just flagged on X. According to the outlet, Polymarket bettors are not optimistic about ‘Dune 3’ pulling ahead of Marvel’s ensemble epic on their shared opening weekend, with the site’s prediction market showing the odds sliding in real time. The post also noted that both films remain locked into the same release day, reinforcing just how directly the two are being pitted against one another in the eyes of bettors and industry watchers alike.
The numbers backing up that skepticism are hard to ignore. ‘Avengers: Doomsday’ presales have reportedly already sold 92 percent of what ‘The Fantastic Four: First Steps’ managed in its entire preview haul, putting the film on pace for more than 100 million dollars in previews alone and a possible domestic opening in the neighborhood of 400 million dollars. Trade analysts have separately projected a domestic opening between 230 million and 260 million dollars for the Marvel sequel, with a worldwide debut potentially clearing 600 million dollars.
‘Dune’ has never operated on quite that scale. ‘Dune: Part One’ earned 410 million dollars globally while also streaming day and date on HBO Max, and ‘Dune: Part Two’ became a genuine theatrical juggernaut with 714 million dollars worldwide. Those are massive numbers for Villeneuve’s franchise, but they still fall well short of what a fully assembled Avengers roster tends to pull in, which helps explain why traders don’t like Dune’s chances on a shared opening weekend.
Exhibitors, for their part, aren’t thrilled about the standoff either. Some theater owners have openly worried that stacking two massive tentpoles on the same day creates a level of overwhelm that simply doesn’t make sense for a marketplace already starved for big releases. Whether that overwhelm translates into a genuine box office event or a split audience remains the biggest open question heading into the holidays.
Neither studio has budged as of now, so ‘Dunesday’ appears to be happening whether Hollywood is ready or not. Do you think ‘Dune 3’ can defy the odds and hold its own against Marvel’s biggest crossover yet, or is this shaping up to be a one sided showdown at the multiplex?
