About the videos
We link to and embed only real, official trailers from Marvel Studios' or Disney's own channels. We never fabricate video links - where an embed isn't shown yet, it's because we're waiting on the official source.
Full trailer - released July 20, 2026
Marvel released the first full trailer online on July 20, 2026, after showing it at CinemaCon in April 2026. It was the first time Robert Downey Jr.'s Doctor Doom appeared on screen - with Doom narrating a warning about a multiversal threat, Thor and Steve Rogers (wielding Mjolnir) featured, and crossover moments between the Avengers, Fantastic Four, and X-Men. Premium “Infinity Vision” tickets went on sale the same day. Confirmed

Official full trailer online
The same trailer arrives online with premium tickets on sale, hitting 503 million views in 24 hours - the second-biggest launch on record behind Spider-Man: Brand New Day.
ConfirmedThe unusual rollout - and the leaks
Marvel tied the four teasers to weekly screenings of Avatar: Fire and Ash, meaning fans effectively had to go to the cinema to catch each one. Every teaser leaked online ahead of its official release anyway - a rollout some commentators found frustrating, though the numbers suggest it worked. The Russo brothers described the teasers as "stories" and "clues" rather than conventional trailers, each carrying a piece of narrative information.
By the numbers
- The March 2025 cast-reveal livestream drew 275 million views in 24 hours, a cross-platform record.
- The four teasers passed 1.02 billion combined views within three days of the fourth.
- The full trailer hit 503 million views in 24 hours - Disney's most-viewed trailer, and the second-biggest launch on record behind Spider-Man: Brand New Day.
What we still don't know
Marvel and the Russo brothers have suggested more footage may arrive before release, but no date for a second full trailer has been confirmed. We'll add it here the moment it's official.
Some fans noted an unusual amount of empty space in one teaser and speculated it was hiding a spoiler. That's fan interpretation, not anything Marvel has acknowledged - see how we handle that on the Theories page. Theory
