A new fan theory suggests Marvel may have already hidden the release date for the first Avengers: Doomsday trailer in plain sight. By tracking the mysterious glitch codes attached to each teaser, online sleuths believe they can pinpoint not only the day, but even the exact hour new footage could arrive.
Avengers: Doomsday theory reveals first trailer’s release date
Avengers: Doomsday is expected to debut its first trailer on February 17, 2026, at 9:00 AM ET, with a “thank you” Instagram Reel planned for 5:00 PM ET the same day.
Marvel Studios, the Russo Brothers, and Robert Downey Jr. are expected to share the posts across their official accounts. A user on Reddit stated, “Avengers doomsday will relased on February 17th at 9:00am (ET) and on same date at 5:00pm (ET) on official marvel instagram we’ll have a secret reel IT’S ALL PLANNED!”
Each teaser contains a glitch code formatted as 1e: XXber:02020, representing a countdown using a 30-day model. The numbers decrease in sequence—24, 17, 11, 4, and 1 days—aligning with a final date of February 17, 2026, at 9:00 AM ET.
A table compiled by the same user lists teaser release dates as:
- December 23, 2025
- December 30, 2025
- January 6, 2026
- January 13, 2026
- January 16, 2026
Marvel released all five teasers at 9:00 AM ET on its official YouTube and Instagram accounts. On January 16, Marvel posted a “thank you for the views” reel at 4:00 PM ET. That reel includes a glitch code pointing to 5:09 PM ET on February 17, suggesting a possible second post or update later that day.
Anthony and Joe Russo directed the film, with Michael Waldron and Stephen McFeely writing the screenplay. Marvel Studios and AGBO produced it. As the 39th film in the MCU, Avengers: Doomsday follows Endgame and premieres on December 18, 2026.
The Avengers, Wakandans, New Avengers, Fantastic Four, and X-Men join forces to fight Doctor Doom, played by Robert Downey Jr. The cast includes returning characters such as Thor, Loki, Captain America, Black Panther, and Magneto. Filming began in April 2025 at Pinewood Studios and wrapped in September 2025. The team plans additional reshoots for early 2026. Alan Silvestri returns to compose the score.
Marvel’s marketing strategy includes a five-hour cast reveal livestream and five teaser reels. Each teaser follows the same countdown pattern and release timing, reinforcing the February 17 trailer launch.
