Tickets for Avengers: Doomsday are now available beyond the previously announced premium-format screenings, expanding advance sales to cinemas in the US. The initial ticket rollout had focused on Infinity Vision-certified premium large-format theatres.
Marvel's decision to expand ticket sales comes months before the film's theatrical release. Avengers: Doomsday is scheduled to arrive in cinemas on December 18, 2026. It will open on the same day as Denis Villeneuve's Dune: Part Three .

Marvel has already released official teaser material for the film, which has increased interest in its massive crossover involving characters from different Marvel universes.
The D23 presentation could also provide more information about Marvel's plans for its upcoming X-Men project and potentially reveal additional details about the studio's wider Phase Six slate.
