Avengers: Doomsday trailer drops with RDJ and star-studded Marvel cast
Which movie has biggest opening weekend in 2026?
Polymarket prices this Avengers: Doomsday at 72%. The reporting broadly agrees.
Marvel released the first full trailer for Avengers: Doomsday on July 20, 2026, giving audiences their clearest look yet at Robert Downey Jr.'s return to the franchise — this time as the villain Doctor Doom rather than Tony Stark. The trailer, covered across outlets from ABC News to Axios, reveals what Axios calls an Infinity Vision twist and showcases a sprawling ensemble cast that, per trekmovie.com, even includes Star Trek's Patrick Stewart and Rebecca Romijn. The film is slated for a 2026 theatrical release and is widely seen as the year's top box-office contender, with traders putting it at 72% to post the largest domestic opening weekend of any 2026 release, a view that has held roughly steady over the past week. ABC News and KJZZ both highlight the sheer density of gathered stars as a central selling point, while The Direct has separately cautioned that Spider-Man: Brand New Day may hold one competitive advantage at the box office. The market resolves on December 30, 2026, using final three-day opening weekend figures from The Numbers.
Background
Avengers: Doomsday is the fifth Avengers film in the Marvel Cinematic Universe and represents a pivot point for the franchise after the Multiverse Saga's mixed reception. Robert Downey Jr., who anchored the Infinity Saga as Iron Man for over a decade, returns in a fundamentally different role — as Doctor Doom — a casting decision Marvel announced in 2024 that generated intense debate among fans and commentators. The film is directed by Joe and Anthony Russo, who previously helmed Avengers: Endgame, the second-highest-grossing film of all time. The specific question at issue is whether Doomsday's three-day domestic opening weekend gross will exceed that of every other 2026 release, with Spider-Man: Brand New Day frequently cited as the most credible rival. The Numbers' Weekend Box Office Performance table will serve as the authoritative data source once final figures are posted.
The precedent
- Avengers: Endgame (2019) holds the record for the largest domestic opening weekend of all time at $357.1 million over its three-day debut.
- No Marvel film released in 2023 or 2024 surpassed a $200 million domestic opening weekend, a threshold every Avengers film through Endgame had cleared.
- The last Avengers film, Avengers: Endgame, was directed by Joe and Anthony Russo — the same directors attached to Avengers: Doomsday.

What the coverage agrees on
- Avengers: Doomsday's first trailer was released around July 20, 2026
- Robert Downey Jr. appears in the film as Doctor Doom
- The trailer reveals a large ensemble cast across multiple franchises
- The film is positioned as a major 2026 theatrical release
How outlets frame it
- Axios: Emphasizes a specific narrative twist — an Infinity Vision reveal — as the trailer's headline element, framing the film around its plot surprises rather than its star power.
- The Direct: Contrasts with the bullish consensus by arguing Spider-Man: Brand New Day holds a meaningful competitive advantage over Doomsday at the box office, introducing a note of caution about Doomsday's dominance.
- trekmovie.com: Foregrounds the cross-franchise stunt casting of Star Trek's Patrick Stewart and Rebecca Romijn, positioning the film as a pop-culture crossover event rather than a pure Marvel property.
What to watch
The film's theatrical release date — not yet confirmed in the current coverage but expected in mid-to-late 2026 — will anchor the resolution timeline, with the market settling on December 30, 2026. Key milestones before then include a second trailer drop, early review embargoes, and advance ticket sales, all of which shape opening-weekend projections. Spider-Man: Brand New Day's own marketing rollout and release date proximity to Doomsday could determine whether it siphons enough opening-weekend demand to complicate the picture.
