A new TV spot says outright that a full trailer is on the way, and D23 opens in Anaheim today. What Marvel has not said is whether the footage leaves the building.
Marvel Studios has been steadily escalating the Avengers: Doomsday campaign all summer, and this week it shifted gear. A TV spot circulating on August 14 states plainly that a complete trailer is imminent. The timing is not accidental — D23 runs from August 14 to 16 in Anaheim.
The confirmed part
The first full trailer went up on July 20 and pulled more than 503 million views inside 24 hours, landing narrowly behind the record set by Spider-Man: Brand New Day. That footage had already screened exclusively at CinemaCon back in April, months before anyone outside the room saw it.
At San Diego Comic-Con, Marvel showed different, newer material during its Hall H panel. It has never been released online. Descriptions are plentiful, though: the sequence reportedly opens with Sue Storm narrating the story of Victor von Doom, positioning the Latverian squarely as the film’s central threat.
The release date has been locked for some time at December 18, 2026. Doomsday is the first half of the Multiverse Saga’s finale, with Avengers: Secret Wars following in 2027. The ensemble is the largest since Endgame, folding the Thunderbolts — the New Avengers — together with the Fantastic Four and the X-Men. Robert Downey Jr. plays Doctor Doom.
Where the insiders disagree
Multiple scoopers, Daniel Richtman among them, expect the second trailer to drop as part of D23, possibly paired with the opening of ticket presales. Marvel and Sony ran precisely that combination for Spider-Man: Brand New Day.
The disagreement is on the question that actually matters. The Beyond Reporter expects the footage to stay behind closed doors, shown only to attendees. ProjectHurts counters that it will go online shortly afterwards. Both agree on one point: whatever screens at D23 is likely the same material that already played in Hall H.
Marvel Studios itself has said nothing about a trailer at D23. Precedent leans against immediate release, given that both CinemaCon and Comic-Con footage stayed exclusive. The showcase is also not being streamed.
When Marvel takes the stage
Everything Disney intends to say about film and television at D23 has been compressed into a single block: the Disney Entertainment Showcase on Friday evening at the Honda Center, scheduled from 7 to 9 p.m. local time. Whether Marvel front-loads the Doomsday segment, buries it mid-show or saves it for the closing minutes is anyone’s guess.
Doomsday is not the only item expected. VisionQuest arrives October 14, 2026 on Disney+ with Paul Bettany, and still has no trailer, making a reveal likely. Reports also point to an X-Men casting announcement, and there is standing hope for some sign of life from Daredevil: Born Again season three. None of that is confirmed either.
Those Doom images are not reveals
Alongside the TV spot, social feeds have filled with shots of Doctor Doom in elaborately detailed armour, glowing logos, and photographs of a throne statue. These come from fan posts and mostly cannot be traced to any official source. They are not marketing material and prove nothing about the contents of the coming trailer. The same applies to the circulating time predictions: a 9 a.m. Pacific release is a fan guess, not an announced slot.
Two ways Saturday morning goes
Either Marvel replays the Comic-Con sequence in the room only, in which case the internet gets the TV spot and another round of secondhand descriptions. Or Disney pulls the trigger on a public release alongside ticket presales, and the second Doomsday trailer is available to everyone before the weekend is out. The only certainty is that a full trailer is coming, because Marvel said so itself. Avengers: Doomsday opens in cinemas on December 18, 2026.
