A24 isn’t done playing in the Backrooms.
The studio just launched a viral marketing site that lets fans do the one thing the movie warns against: join the Async Research Institute.
The site, async.backrooms.mov, invites visitors to generate their own personalized Async employee ID badge â name, job title, and photo included.
The digital badge is a free download, and for $10, fans can order a physical copy of the card. A24 announced it with a post that’s already pulled in over 640,000 views in its first day.
It’s the latest move in what’s quietly become one of the smartest marketing campaigns in horror, and the box office numbers say it keeps working.
The Badge Is Pure Deep-Cut Lore
For casual moviegoers, the badge is a fun souvenir. For fans of Kane Parsons’ original web series, it’s loaded.
The card is issued by the Async Research Institute â the shadowy company behind everything in the Backrooms mythology â under its “Magnet Systems R&D” division, stamped “CLEAR Q4.” The dates are the tell: issued November 14, 1989, expiring January 1, 1991.
In the series lore, Async opened the Threshold into the Backrooms on October 17, 1989. Your badge makes you a fresh hire in the exact window when everything started going wrong.
That’s the kind of detail that doesn’t happen by accident. It’s marketing built by people who actually know the mythology â which tracks, given the mythology’s creator is the guy who directed the movie.

A Campaign That Never Broke Character
A24 has been running the Async bit in character for months.
Ticket buyers got early access to an Async Research Institute hat back in May. The Burbank pop-up experience had an Async-branded van parked outside and in-character “researchers” who would periodically escort guests out of the building.
Last week, the studio posted an hour of pure Backrooms ambience â buzzing fluorescent lights and empty yellow rooms â as the Everything Must Go Edition hit theaters.
None of this is traditional movie marketing. It’s world-building. A24 is treating the campaign the way Parsons treated his YouTube series: as an ongoing piece of the fiction fans can step into.
And that’s exactly the language this audience speaks: the film’s fanbase grew up decoding this stuff frame by frame in YouTube comments and wiki pages.

The Receipts: The Re-Release Just Posted The Best Hold Of The Run
Here’s where the strategy shows up in the numbers. Per Box Office Mojo, Backrooms has now grossed $349.8 million worldwide â $190.5 million domestic and $159.3 million international â extending its record as A24’s biggest movie ever.
But look at the weekend-to-weekend trend. After a frontloaded opening, the drops ran -67.7%, -56.1%, -37.7%, and -38.9%. Then the Everything Must Go Edition landed, and the July 3â5 frame fell just 24.5%, the best hold of the film’s entire run, in its sixth weekend, when most horror movies are long gone from theaters.
That’s not an accident either. Fresh footage plus a fanbase that’s been kept engaged with badges, hats, pop-ups, and lore drops equals people still buying tickets in week six. The marketing and the legs are the same story.
It also keeps Backrooms in a genuine photo finish with Obsession, which was last reported around $333 million and still climbing. The two YouTube-born horror movies are now running neck-and-neck as 2026’s biggest creator-driven hits, a race nobody in Hollywood saw coming six months ago.

The YouTube Playbook, Institutionalized
Step back and the badge site is the whole 2026 story in miniature.
Parsons built Backrooms by giving an online audience lore to obsess over, artifacts to dissect, and a world to feel part of. A24 didn’t replace that playbook when it bought in, it scaled it up. The studio is marketing the movie the way the creator built the audience.
Compare that to the year’s high-profile flops, which treated their built-in audiences as guaranteed instead of giving them something to engage with.
The gap between those two approaches is the gap between a $10 million movie approaching $350 million and tentpoles that couldn’t open.
With Backrooms 2 confirmed to be in the works, expect the Async campaign to keep going, the badge is probably less a farewell souvenir than an onboarding document.

How To Get An Async ID Badge
Fans can create a badge at async.backrooms.mov by entering a first name, last name, and job title, and uploading a photo.
The personalized digital badge is free to download, while a physical copy of the card runs $10.
The badge is labeled as a promotional prop, so no, it won’t actually get you past Async security. Probably for the best, given the employee retention numbers.
