The DC Studios blockbuster Supergirl starring Milly Alcock has received a strong Rotten Tomatoes prediction. Directed by Craig Gillespie and produced by James Gunn and Peter Safran, the superhero flick has been pitched as an offbeat, Guardians of the Galaxy-ish slant to David Corenswet’s Superman. Trailers for the space-faring action-adventure see Supergirl, or Kara Zol-El, party-hopping across the universe before a group of space pirates shoot her dog Krypto with a poisonous projectile. In addition to Corenswet, who makes more than several appearances as The Man of Steel in the recent trailer, the Warner Bros. movie features Jason Momoa as bounty hunter Lobo. Supergirl arrives in theaters nationwide on June 26, 2026.
Supergirl is on track to be ‘Certified Fresh’ (but just barely)
As of June 10, Supergirl is predicted to earn a 76% critics rating on Rotten Tomatoes based on a bet on Kalshi. This is right near the borderline for a film to receive the site’s “Certified Fresh” rating that is given to movies with a score of 75% or higher. The full results for the bet can be found below:
- Above 30 (Rotten Tomatoes rating) – 98% chance
- Above 35 – 97%
- Above 40 – 99%
- Above 45 – 94%
- Above 50 – 93%
- Above 55 – 89%
- Above 60 – 87%
- Above 65 – 83%
- Above 70 – 71%
- Above 75 – 53%
- Above 80 – 38%
- Above 85 – 21%
- Above 90 – 6%
- Above 95 – 2%
Since the start of the bet on May 13, the predicted RT score for Supergirl has steadily grown over time, from a low of 68% to its current mark of 76%. There was a sharp spike on June 6 where the forecasted score vaulted up to 96%, but that quickly dropped down, showing just how volatile these predictions can be. (So it’s crucial to take this bet with a grain of salt.)
We won’t know more about Supergirl’s Rotten Tomatoes rating until a few days before the movie makes its debut. According to EmbargoLiftsFor on X (formerly Twitter), the review embargo for the film will lift on June 24 at 9 AM PT / 12 PM ET, just a couple of days before it comes out. Its social media embargo should lift earlier than this, so we expect initial reactions to the movie from critics to appear on the platform soon.
By comparison, this estimated Rotten Tomatoes score for Supergirl is lower than the 83% rating for 2025’s Superman and the 86% rating for The Fantastic Four: First Steps. On the other hand, it’s much higher than the 46% that Captain America: Brave New World received.
If this prediction for Supergirl’s RT rating holds, it will provide much-needed word of mouth for a film that is expected to struggle to break even at the box office. A June 5 report from BoxOfficeTheory has the superhero flick earning $56 million in its domestic opener, which is lower than Toy Story 5’s projected $155 million and Minions & Monsters’s projected $57 million.
For its entire domestic run, the movie is expected to bring in $137 million. According to Deadline, the reported budget for Supergirl is $175 million before print and advertising costs and that its break-even point is $315 million at the global box office, so the $137 million prediction is on the low end, suggesting that the film will need a very strong international performance to make a profit.
Despite rumors that Supergirl has a lot of profanity, James Gunn has confirmed that there are actually no F-bombs in the movie. Recent visits to the film’s set made fans believe that the curse word would appear in the final cut of the movie. The director also clarified questions about how Supergirl has ear piercings in the trailers given her Kryptonian powers and said that she went to planets with a red sun to get the procedure done (it’s the same way that she gets drunk too).
