Demon Slayer: Infinity Castle Outswings the Top Spider-Man Movie of the 2020s at the Box Office

Demon Slayer just woke up in 2025, cracked its knuckles, and decided to lap Spider-Man at the box office. And, yep, it did exactly that.

The new top dog at the global box office

According to Box Office Mojo, 'Demon Slayer: Kimetsu no Yaiba - The Movie: Infinity Castle' has cleared $729 million worldwide so far, pushing past 2023's 'Spider-Man: Across the Spider-Verse' and its $690 million run. That is not a photo finish; that is a comfortable lead.

The momentum has been obvious on the ground too: packed theaters, sold-out shows, and a steady streak of new records over the last few weeks as the film opened wider and word of mouth snowballed.

'Infinity Castle plays like the main event, not a bonus chapter.'

Why this hit landed the way it did

If you have read the manga, you know the Infinity Castle storyline is the big swing. It is the payoff arc — dramatic, chaotic, emotional, and designed to melt eyeballs. Ufotable made a very specific choice to put that scale on a movie screen instead of stretching it into another season, and the bet worked. This does not feel like a side story or a cash-in; it feels like the culmination fans have been waiting for.

Also, the audience was more than ready. From everyone who sobbed through 'Mugen Train' to the casual viewers who discovered Demon Slayer through endless social clips (and the adults quietly marathoning at 2 a.m.), the turnout was immediate and loud.

About that Spider-Verse comparison

'Across the Spider-Verse' is still one of the best Western animated films in years — inventive, wildly influential, and a standout among Spider-Man releases. But Demon Slayer had something Spider-Verse did not this time: a tidal-wave level of worldwide hype that functioned less like a standard release and more like a cultural moment. In raw theatrical numbers, Infinity Castle wins.

And this is another reminder that anime films are not niche alternatives anymore. When the story stakes are high, the animation is top-tier, and the emotional payoff lands, these movies can go toe-to-toe with Hollywood and come out ahead. Ufotable delivered exactly what the fanbase asked for: massive stakes, pristine action, and a clean emotional catharsis.
