‘Dunesday’ Is Being Tipped to Smash ‘Barbenheimer’s’ Box Office Record Before It Even Happens

Hollywood spent years chasing another moment like the summer of 2023, when two wildly different blockbusters opening on the same day turned into a genuine cultural event rather than a scheduling conflict. That single weekend reshaped how studios think about counterprogramming, proving that audiences don’t always have to pick a side.

Now, more than three years later, the industry appears to be on the verge of another one of those rare moments, and this time it’s coming from two franchises with massive built-in fan bases of their own. Rather than a quirky pairing of a toy movie and a biopic, this next collision pits two of the biggest names in blockbuster filmmaking directly against each other.

‘Dunesday’ is projected to beat ‘Barbenheimer’s’ domestic opening weekend record, according to Polymarket.com traders. The prediction market currently shows a 93% probability favoring that outcome, referring to Warner Bros. and Denis Villeneuve’s ‘Dune: Part Three’ opening the same day as Disney and the Russo Brothers’ ‘Avengers: Doomsday.’

That same-day release lines up for December 18, setting up a showdown directly mirroring the ‘Barbenheimer’ phenomenon that saw ‘Barbie’ and ‘Oppenheimer’ combine for $235.5 million domestically back in July 2023. Industry analysts have already speculated that this new pairing could push past that combined total, given how both films represent the conclusions of two of the most anticipated franchise arcs in recent memory.

Unlike the original ‘Barbenheimer’ pairing, which combined an original comedy with an R-rated historical drama, both ‘Dune: Part Three’ and ‘Avengers: Doomsday‘ are PG-13 tentpoles with broad, overlapping appeal. Early ticket sales for both films have reportedly already caused ticketing sites to crash, suggesting the demand is real rather than just online hype.

‘Dune: Part Three‘ arrives as the conclusion to Denis Villeneuve’s Arrakis-set trilogy, following ‘Dune: Part Two’s’ strong $82.5 million domestic opening and $178.5 million worldwide debut in 2024. Since this installment wraps up the saga entirely, box office analysts believe the film is positioned to close out the trilogy on a genuinely massive note.

‘Avengers: Doomsday’ carries its own historic weight as one of Marvel’s most ambitious crossover events, reuniting the Russo Brothers with a sprawling ensemble cast that includes Robert Downey Jr. as Doctor Doom. Given the franchise’s track record of setting opening weekend records, its pairing with ‘Dune: Part Three’ has fueled speculation that this could become one of the biggest collective box office weekends of all time.

Rather than worrying about the two films cannibalizing each other’s audience, industry experts have suggested the double-feature dynamic could actually lift both titles simultaneously, echoing exactly what happened with ‘Barbie’ and ‘Oppenheimer’ three years earlier. That same counterprogramming logic, two wildly different tones under one shared release date, appears to be working in both films’ favor heading into December.

With Polymarket traders showing overwhelming confidence in a new record, all that’s left is for ‘Dunesday’ to actually deliver once December 18 finally arrives. If the hype holds, this could end up being remembered as one of the defining box office weekends of the decade.
