Overview
- The film concluded its worldwide theatrical run on Wednesday, August 5, 2026, with a final global total of $125.8 million, according to box office tallies.
- That result places Supergirl as the weakest DC theatrical performer since 2004's Catwoman and below other noted comic‑book flops such as Morbius and Joker: Folie à Deux.
- Industry estimates cite a reported production cost near $170 million plus tens of millions in marketing, a combination that makes the theatrical run likely unprofitable.
- Supergirl opened to mixed reviews and a roughly 56 percent score on Rotten Tomatoes and suffered steep week‑to‑week box office declines that prevented growth after opening weekend.
- DC Studios leaders have publicly described the film as a single setback while moving the title to digital now and planning a 4K Blu‑ray release on September 8, and studio watchers expect tighter budgets and closer oversight on upcoming DCU projects.
