A new rumor suggests that the Supergirl trailer could be coming out sooner than people think.

When is Supergirl’s trailer potentially coming out?

According to a recent report from The Breakroom, the Supergirl teaser trailer will be shown to select members of the media this weekend at CCXP. After that, a “possible online release” could come as early as Monday, December 8, 2025.

Of course, nothing is confirmed as of now, but with rumors also suggesting that Avengers: Doomsday and The Odyssey are releasing trailers soon, DC Studios may want to show off their trailer ahead of time. With CCXP continuing to go on this weekend, we’ll likely get more information leading up to Sunday.

Supergirl: Woman of Tomorrow will be based on Tom King’s 2021-2022 comic book series, which Bilquis Evely illustrated. The film stars Milly Alcock, who will play the titular role of Kara Zor-El and will be written by Ana Nogueira and produced by DC Studios co-CEOs James Gunn and Peter Safran.

“We will see the difference between Superman, who was sent to Earth and raised by loving parents from the time he was an infant, versus Supergirl, who was raised on a rock, a chip off Krypton and watched everyone around her die and be killed in terrible ways for the first 14 years of her life, and then came to Earth when she was a young girl,” said Gunn of the project in 2023. “She’s much more hardcore; she’s not exactly the Supergirl we’re used to seeing.”

Supergirl: Woman of Tomorrow will be based on Tom King’s 2021-2022 comic book series, which was illustrated by Bilquis Evely. The film is directed by Craig Gillespie with a release date currently set for June 26, 2026.
