Could ‘Avengers: Doomsday’ Shatter the All-Time Domestic Opening Weekend Record?
The box office has already witnessed history this year. In July, ‘Spider-Man: Brand New Day’ opened to a staggering $360.1 million domestically and $932 million worldwide, narrowly edging past the $357.1 million debut of ‘Avengers: Endgame’ to claim the biggest domestic opening weekend of all time.
Now Marvel is preparing for its next giant swing. ‘Avengers: Doomsday’ arrives on December 18, and its presales have been unlike anything the industry has seen, starting with $16.5 million in premium-format tickets sold in the first 24 hours when sales opened in July.
That momentum has analysts wondering just how high the film can go. As Boxoffice Pro posed on its podcast, the industry may be on the verge of the first-ever $400 million domestic opening weekend, a milestone the outlet says is by no means guaranteed but definitely in play for ‘Avengers: Doomsday’.
The outlet also pointed to a very promising fourth quarter ahead. With the Russo brothers’ crossover leading the charge, December could deliver one of the strongest box office stretches in recent memory. If ‘Doomsday’ clears the $400 million mark, it would mark the second time in a single calendar year that Marvel resets its own opening weekend record.
The buzz is grounded in remarkable advance sales. ‘Doomsday’ became the first film to pass $40 million in domestic presales roughly 100 days before release, and Disney has since confirmed that domestic advance sales have topped $50 million.
Are we on the verge of the first ever $400M domestic opening weekend? It’s by no means a guarantee, but definitely in play for AVENGERS: DOOMSDAY this December. https://t.co/v5Q6p6xQC9

Globally, tracking firm Global Box Office reported the film crossed $100 million in presales on October 6, and the total has reportedly since climbed past $125 million. Overseas, it became the fastest film ever to pass $1 million in pre-release sales in both Brazil and the U.K.
Not everyone agrees on where the opening will land. Global Box Office has projected a domestic debut between $260 million and $300 million, which would be enormous but still short of the record.

Others are far more bullish. Tracker AnthonyJPHer has forecast around $120 million in Thursday previews and an opening weekend between $425 million and $450 million, while World of Reel previously suggested a debut in the $400 million range.
Prediction markets reflect that uncertainty. A Manifold market asking whether ‘Doomsday’ will break the all-time domestic opening record traded at 43% implied probability as of October 25.
Analysts have warned that early presales may not translate directly into opening weekend results. No blockbuster has opened advance sales this early, meaning the numbers are naturally front-loaded compared with films that sell tickets for only a few weeks.

The film also won’t have IMAX screens on opening weekend, since ‘Dune: Part Three’ holds the format exclusively for 3 weeks. Despite that limitation, ‘Doomsday’ has continued to perform strongly across other premium formats.
The December 18 frame could be record-breaking regardless of whether ‘Doomsday’ tops $400 million. Tracker EmpireCity Box Office expects the Marvel film to outgross ‘Dune: Part Three’ by a ratio of roughly 3.2 to 1 or even 4 to 1.
Should both films clear $100 million, it would be the first time 2 separate films opened above that threshold on the same weekend. Many analysts expect Dunesday to set a new overall domestic weekend record.
