When is the Avengers: Doomsday trailer coming out? Its all that Marvel fans have been asking for the past two months. Ever since it became clear that Marvel Studios planned to unveil something at CinemaCon, fans have been ready for a sneak peek of the upcoming game-changer but in the aftermath of the event itself, those requests, hopes, and longing have only intensified - primarily because the studio opted not to release the CinemaCon trailer online.
We are now a month out from CinemaCon and the trailer still hasn't surfaced online, despite an overwhelmingly positive response from the audiences in attendance (and the millions of fans who read the footage descriptions and breakdowns in the days after that). And although there was hope that it might be attached to the upcoming release of The Mandalorian and Grogu, it's beginning to sound like that won't be the case (at least according to the most recent update).
The good news is that, regardless of whether there is any teaser between now and then, we know where we can expect a full-length Avengers: Doomsday trailer.
The Avengers: Doomsday trailer will likely headline Marvel Studios' SDCC panel
You probably knew this one was coming. Marvel Studios is reportedly returning to Hall H this year, where it will tease audiences with what's to come from the Marvel Cinematic Universe. This year's panel puts them in a very unique place, however, because as of this moment, the film that they can really promote is Avengers: Doomsday (Spider-Man: Brand New Day is a joint-venture with Sony and 2027's Avengers: Secret Wars is a direct sequel to Avengers: Doomsday). And, honestly, that is pretty fitting when you think about.
The upcoming movie is set to act as the opening act of the Multiverse Saga's conclusion, meaning that 35 titles (15 movies, 17 Disney Plus shows, and 3 Special Presentations) will have all been building towards its release. And with that, it would make sense that Marvel devote an entire panel to the film. After all, there is a huge cast of 30+ Marvel stars expected to feature, which includes cast members from the original Avengers movies, Thunderbolts*, The Fantastic Four: First Steps, and even the classic X-Men movies. We will likely see appearances from them, especially the returning Robert Downey Jr., who is set to play new MCU villain Doctor Doom.
Avengers: Doomsday has been a presence in Marvel fans' lives now for the past two iterations of San Diego Comic-Con. Back in 2024, the studio officially announced that Avengers: The Kang Dynasty would evolve into Avengers: Doomsday, bringing Downey Jr. out onto stage to confirm his casting as the formidable Victor von Doom. Kevin Feige and the gang then famously sidestepped it altogether in 2025 as production was underway on the movie and all involved wanted to focus on building anticipation while ensuring that the finished product would be up to scratch. Now, they will get the chance to show some of it off at SDCC this year.
Taking all of that into account, of course we can expect a teaser trailer from Marvel Studios at the event this year. Although they have yet to announce who or what they are bringing to Hall H in San Diego this time around, the studio's preference to use the Comic-Con stage to tease upcoming movies leaves Doomsday as the only option. And with that, a trailer will almost certainly ensue.
While it would have been really nice to see the CinemaCon trailer surface online at some point after its exclusive unveiling to the audiences in attendance, it was honestly unlikely for one specific reason: It's too early to release a first look that extensive to wider audiences. The film is still seven months away (eight at the time of CinemaCon) and this is much too soon to unveil a story-centric teaser trailer.
Granted, Marvel Studios did unveil four character-centric Avengers: Doomsday teasers throughout the release of Avatar: Fire and Ash, but again, those were character-centric teases that didn't give anything away about the movie itself. Based on what happens in the CinemaCon teaser, it's understandable that Marvel opted to hold onto that one, while allowing the breakdowns to generate the buzz for them.
By the time that San Diego Comic-Con rolls around, however, we're going to be just five months away from its theatrical release in December. And then, the first full teaser trailer will be unveiled. Better yet, it will probably be a brand new one designed to capture the intrigue from the CinemaCon footage breakdowns while also offering up its own unique moments that will have us all talking through the back half of the year as we await the movie's official release.
Avengers: Doomsday arrives in movie theaters on December 18, 2026.
