The first official trailer for "Avengers: Doomsday" has become the second-most-viewed movie trailer debut in history, racking up 503 million views in its first 24 hours. The result underscores the enduring commercial pull of the Avengers franchise, even after a seven-year absence, and comes six months ahead of the film's cinema release, suggesting strong early demand for Marvel's next major crossover.

The trailer trails only "Spider-Man: Brand New Day," which holds the overall record with 719 million views, but it now stands as Disney's most-viewed trailer launch ever, well ahead of the 365 million views earned by the 2024 Super Bowl teaser for "Deadpool & Wolverine". Footage revealed the Avengers joining forces with the X-Men against Robert Downey Jr.'s Doctor Doom, featuring the returns of Chris Evans as Captain America, Chris Hemsworth as Thor, Florence Pugh as Yelena Belova, Patrick Stewart as Professor X and Ian McKellen as Magneto, alongside Channing Tatum's Gambit.
