New Box Office Projections Put Supergirl on the Ropes—Breaking Even Now a Battle

If you thought DC was content to rest on its Superman-shaped laurels, brace yourself: Supergirl is swooping in as the next big play in James Gunn's rebooted DC universe. This time it’s Milly Alcock, yes, the one from House of the Dragon, donning the cape as Kara Zor-El – and no, the script isn’t doing her many favours when it comes to easy box office wins.

Supergirl, but Make It a Marathon

Directed by Craig Gillespie, Supergirl marks the second chapter under Gunn’s new DC regime. Alcock popped up briefly in David Corenswet's Superman, and now she’s centre stage. You’d think that’d set her up for a win, especially with all the intergalactic party-hopping – and Krypto, the superhero dog, as her sidekick. Trouble is, the plot literally goes to the dogs: Krypto gets poisoned by space pirates (points for creativity), setting Kara on a quest for an antidote. Throw in an encounter with Lobo (played by Jason Momoa, who apparently never gets tired of playing rowdy antiheroes), and you’ve got the DC equivalent of a cosmic pub crawl with murder and misery at every stop.

The Hollywood Numbers Game

The real headline? Box office watchers are already setting their expectations somewhat grimly. Projected domestic opening for Supergirl is between $47 million and $65 million from 26 to 28 June 2026. In total, the film’s US haul could land somewhere between $107 million and $181 million if things go pretty well, according to BoxOfficeTheory and the collective fortune-telling wisdom over on Reddit’s r/boxoffice.

Now, for context – and a reality check – last year’s Superman reboot pulled in a much juicier $125 million on its domestic opener and ended up making $618 million globally. Of that, $354 million was from the States and $264 million was international. Despite the big numbers, with Superman costing a steep $225 million to make, it only managed to claw itself into profit territory right at the finish line. Blockbuster accounting says you need about 2.5 times your budget to actually turn a profit after marketing and other bits are paid for, which meant Superman needed to break the $562 million mark. Ouch.

Counting the Pennies: Budgets and Breakeven

As for Supergirl, no one’s officially coughed up the real budget, but the best outsider guesses put it between $170 million (cheers, Puck) and $200 million (cheers, Forbes last December). If we’re letting optimism lead and use the lower figure, it still means Supergirl has to make north of $425 million just to break even—let alone call itself a hit.

• Supergirl – Budget: £170-200 million (depending who you ask)
• Needed to break even: £425+ million globally
• Projected US opening: £47-65 million
• Projected total US take: £107-181 million
• Superman (2025): £125 million opening, £618 million total (worldwide budget: £225 million)

So, even if Supergirl has strong turnout overseas and lucks into healthy word-of-mouth, matching the domestic and international splits from Superman still leaves a yawning gap between hopeful receipts and making the accountants sleep well at night.

A Summer Crowded with Heavy Hitters

And as if that wasn’t enough, Supergirl’s release date is, frankly, a nightmare. It hits cinemas right in the meat of blockbuster summer, and here’s what she’s up against:

Two weeks before, you’ve got Steven Spielberg’s sci-fi offering Disclosure Day (12 June). One week before, Toy Story 5 (19 June) arrives – and that one’s expected to open somewhere between $130 million and $160 million, more than double Supergirl’s projected best case scenario. Then, just five days after Supergirl lands, Minions & Monsters charges in (1 July), followed by Disney’s live-action Moana on 10 July. Frankly, you’d need superpowers just to hold onto a decent chunk of the audience through all that.

Not surprisingly, Fandango’s fan anticipation survey for summer 2026 has Supergirl in ninth place. Toy Story, Moana, and Minions & Monsters are all higher up the “must-see” list with regular punters.

Any Bright Spots for Supergirl?

Well, a couple of tiny glimmers exist. First, Supergirl does get a (very brief) window where it’s the only major superhero release between DCU and MCU, before Spider-Man: Brand New Day swings in on 31 July. On top of that, the trailers seem to be generating a bit of online buzz – 24 million YouTube views on the teaser, then 27 million for the full March trailer. That sort of internet activity could mean actual bums in seats… or it might just mean people like watching trailers.

Bottom line: with all this lined up against her, Supergirl is going to need more than puppy love and a decent right hook to stand out in the summer carnage. Still, sometimes word-of-mouth and critical praise, if they show up, can actually move the needle. At this point, a lot rests on how things look much closer to release.
