Avengers: Doomsday tickets are going on sale shortly — and some fans are convinced that Marvel will surprise us, and reveal the new MCU movie's official trailer, too

• Avengers: Doomsday pre-sale tickets will go live later today (July 20)
• Fans think the new Marvel movie's first trailer could be released, too
• It would be an unusual move for Marvel to make, for one major reason

Avengers: Doomsday tickets are finally set to go on sale later today (July 20) — and Marvel fans think the movie's first trailer could drop at the same time, too.

As revealed by The Hollywood Reporter earlier this month, cinephiles and comic-book fans alike will be able to pre-book their seat for one of 2026's hottest new movies very soon. And, with some theater chains, such as US-based company Regal, already telling fans where they'll be able to watch Doomsday in come December 18, fans will be able to buy advanced tickets before the day is over.

That's not the only Marvel-related thing that might happen today, though, because some people believe the pre-sales launch will coincide with the debut of Doomsday's official trailer.

In screenshots posted to Reddit pages including r/MarvelStudios, r/MarvelStudiosSpoilers, and r/LeaksandRumors, the app for popular US movie ticket company Fandango appeared to indicate that a new trailer would accompany the film's pre-sales launch.

Less than an hour later, users in a separate r/LeaksandRumors thread noted that the trailer banner had been scrubbed from the Fandango app. Some are seeing this as confirmation that we'll soon get a fresh look at the Marvel Phase 6 film — but I'm not entirely convinced that'll be the case.

Why Marvel shouldn't — and should — hold off on releasing a new trailer for Avengers: Doomsday

If Marvel unveils Avengers: Doomsday's fifth trailer — remember, four bite-sized teasers were released between December 2025 and January 2026 — today, it wouldn't be a complete shock.

Indeed, releasing a new trailer, which would likely end by telling people that they can pre-book tickets now, would further ramp up interest in the Marvel Cinematic Universe (MCU) movie, and generate even more ticket sales. Releasing more new footage before Marvel holds its latest Hall H panel at San Diego Comic-Con (SDCC) 2026, which will take place on Saturday, July 25, would also give it more time to highlight some of its other forthcoming film and Disney+ projects during said presentation, because Doomsday wouldn't dominate proceedings.

With SDCC 2026 just days away, though, I'm baffled by the suggestion that Marvel would release Doomsday's first trailer earlier than expected. The aforementioned flick is the comic titan's most anticipated movie in years, and, considering that past editions of SDCC have been where Marvel has made the biggest announcements and reveals about myriad films, I can't foresee a one-off change to that tried and tested — not to mention highly successful — strategy.

I guess we'll find out one way or the other in the hours ahead. For now, find out everything we know so far about Avengers: Doomsday.
