Resolution criteria

The market will resolve based on the official runtime of Avengers: Doomsday as listed on major film databases (IMDb, Rotten Tomatoes, or official Marvel Studios sources), including end credits and post-credit scenes. Resolution will occur after the film's theatrical release on December 18, 2026.

Background

Reports circulating on X suggest Avengers: Doomsday is expected to run for around three hours and forty-five minutes, though Marvel has not officially confirmed the duration. If accurate, the film would be longer than Avengers: Endgame, making it potentially the longest Marvel Studios film to date. The film focuses on the Avengers, Wakandans, Fantastic Four, Thunderbolts, and the "original" X-Men teaming up to face Doom, which may account for its substantial length.

Considerations

Runtime reports for unreleased films are often speculative and subject to change during post-production. Final runtimes may differ from current estimates, particularly if additional reshoots or editing adjustments occur before release.
