Why Supergirl's Box Office Plummeted in Week Two, Explained

There are box-office dips, and then there’s what happened to Supergirl in its second weekend — a collapse that felt like a plot twist no one saw coming. Released on June 26, the film opened to a respectable domestic debut of $37.1 million, but the momentum evaporated fast.

By the end of week two, Supergirl had added only about $9.6 million domestically, a staggering 74.1% drop from week one. To put that in context: the freshly rebooted DC universe’s first outing, Superman, launched with roughly $125 million, and Supergirl’s opening didn’t even reach a third of that figure. Audiences simply didn’t come back. Why?

Critics and box-office trackers point to a mix of factors: franchise fatigue, marketing that struggled to connect beyond core comic fans, and a crowded summer slate. Competition also mattered. Supergirl slid from second place to fourth in the weekly chart, bumped by Minions & Monsters at number one, Toy Story 5 in second, and Young Washington holding third.

That kind of second-week hemorrhage has precedent among recent superhero misfires. Joker: Folie à Deux and The Marvels suffered second-week drops north of 78–81%, The Flash fell about 72.5%, and even Kraven the Hunter and The Suicide Squad saw declines in the low 70s. Supergirl now joins a worrying club where opening-week interest didn’t translate into staying power.

The business math is blunt. Analysts estimate the film needs roughly $300 million worldwide just to approach profitability. Variety’s recent estimate that Supergirl could cost DC Studios between $100 million and $120 million in losses suddenly seems plausible rather than alarmist.

Does this mean the DC reboot is doomed? Not necessarily. Supergirl is only the second release in this new arc. Still, if the next chapter, Clayface, also underperforms or fails to galvanize audiences, studio executives will face tough choices. They may be nudged back toward the safety of marquee names — the characters audiences already know and buy tickets for.

There are future tentpoles on the slate — Man of Tomorrow slated for 2027 and The Brave and the Bold, which has no fixed date yet — so the DCU has breathing room to regroup. But the clock is ticking. Will the studio pivot fast enough to steady the ship, or will these early missteps force a broader rethink of strategy? The next box-office weekends will tell, and we’ll be watching every number.
