‘Obsession’ vs. ‘Backrooms’: Who Won the Box Office Clash?

The summer of 2026 belongs to a pair of horror films that nobody inside the studio system created, and almost nobody predicted would perform like this. Two YouTube filmmakers, armed with almost comically small budgets and enormous online fanbases, have turned the domestic box office into their personal proving ground. The conversation that began weeks apart has now merged into one question the industry cannot stop asking: between ‘Obsession‘ and ‘Backrooms‘, who actually did it better?

It is a genuinely difficult question to answer, because both films have delivered numbers that defy conventional analysis. Their stories are different in almost every way except the outcome, which is a Hollywood industry shaken out of its comfort zone by a generation of creators it largely underestimated.

The Slow Burn Miracle Behind ‘Obsession’

‘Obsession’ was made by Curry Barker, a 26-year-old filmmaker who shot the entire film in just 20 days on a budget of $750,000. The premise follows a music store employee who purchases a supernatural toy to make his longtime crush fall in love with him, with horrifying consequences. After its debut, audiences and critics were equally enthusiastic, with the film earning an “A-” grade on CinemaScore exit polls and a 94% score on Rotten Tomatoes.

What made ‘Obsession’ genuinely historic was its second-weekend performance. The film soared to $23.9 million over the Memorial Day weekend, a record-smashing increase of 39.4 percent over its opening haul of $17.2 million from 2,615 theaters. That represents the biggest spike in modern times for a movie playing in more than 2,500 theaters outside the Christmas holidays.

Comscore chief box office analyst Paul Dergarabedian, who has been tracking and analyzing box office for 33 years, said he thought he had seen it all until that weekend, calling the performance of ‘Obsession’ something that required no caveats. Those are the kinds of quotes analysts reserve for events that genuinely have no precedent.

After three weekends of release, ‘Obsession’ had grossed $106 million domestically and $148 million worldwide against a budget of less than $1 million. That includes a third weekend of $26 million, which itself marked a 10% increase over the second-weekend haul of $24 million. No horror film has achieved consecutive weekend gains of this scale outside the holiday season in modern memory.

The Record-Obliterating Debut of ‘Backrooms’

If ‘Obsession’ built its legend slowly, ‘Backrooms’ arrived like a demolition crew. A24’s buzzy horror film, directed by 20-year-old YouTube phenom Kane Parsons, obliterated box office expectations with $81 million domestically and $118 million worldwide in its opening weekend alone. The film is adapted from Parsons’ viral YouTube series about liminal spaces, those eerie, seemingly endless yellow-tinged rooms that first spread across internet forums before becoming a genuine cultural phenomenon.

The story follows a furniture store owner played by Chiwetel Ejiofor, who finds a secret doorway leading him into a seemingly endless stretch of nondescript rooms. When he disappears, his therapist, played by Renate Reinsve, ventures into the unknown to rescue him. James Wan, Shawn Levy, and Osgood Perkins served as producers on the project.

‘Backrooms’ set multiple benchmarks in a single weekend. It delivered the largest opening weekend ever for A24, crushing the record set by Alex Garland’s 2024 thriller ‘Civil War’ with $25.5 million. It also ranked as the biggest debut in history for an original horror movie, as well as the best start for a first-time filmmaker on a non-franchise film.

Audience data showed that 88% of the opening weekend crowd was under 35, and the overall audience skewed 62% male. Social media analytics firm RelishMix measured the film’s social universe across TikTok, YouTube, Instagram, X, and Facebook at 220 million, placing it 48% ahead of original horror norms, with audiences treating the film less like a studio release and more like the culmination of a long-running internet phenomenon.

YouTuber Filmmakers and the New Hollywood Pipeline

The success of both films cannot be fully understood without appreciating the broader moment they represent. Parsons and Barker are part of a wave of YouTubers making the leap to the mainstream by bringing their enormous online fanbases along with them. Earlier in the year, YouTube creator Mark Fischbach, known online as Markiplier, directed, self-financed, and distributed the horror film ‘Iron Lung’, which earned $50 million against a $3 million budget.

Jason Blum, who produced both ‘Backrooms’ and ‘Obsession’ through his company Blumhouse-Atomic Monster, called YouTube a new place to look for the next generation of groundbreaking talent, believing it is up to Hollywood to cultivate the ones with genuine artistic promise. That is a notable shift in perspective from an industry that has long been skeptical of internet-native creators.

After ‘Obsession’ made its festival debut at TIFF, studios entered a bidding war for the project, with Focus Features ultimately acquiring it for $15 million. Meanwhile, A24 and Chernin Entertainment co-financed ‘Backrooms’ for roughly $10 million, a figure that already looks like one of the shrewdest investments in recent Hollywood history.

Obsession vs Backrooms: Breaking Down the Box Office Numbers

So who actually did it better? On raw opening weekend power, ‘Backrooms’ wins without debate. ‘Backrooms’ crossed $100 million at the domestic box office in just six days, becoming A24’s highest-grossing movie stateside and surpassing the benchmark just established by ‘Marty Supreme’ with $96 million. That kind of velocity is almost without parallel in the modern era for an original property.

But the efficiency argument firmly belongs to ‘Obsession’. The film was made for less than $1 million and likely less than $10 million to market, and it has earned more than 140 times its reported production budget. ‘Obsession’ is the first film since 1982 to increase in both its second and third weekends outside of Christmas. The comparison point there is ‘E.T. the Extraterrestrial’, which gives some sense of how absurd this achievement genuinely is.

Both films also benefited from glowing critical reception. Only five other horror movies, including last year’s breakout ‘Weapons’, have secured an “A-” grade or higher on CinemaScore since 2019. Together, ‘Obsession’ and ‘Backrooms’ represent something the industry rarely gets to celebrate: two original horror films, made outside the franchise system, thriving at the same time.

It all feels like a passing-of-the-guard moment, with both Parsons and Barker signaling a new generation of filmmakers who are rewriting how Hollywood stories get made and who gets to tell them. The box office simply confirmed what the internet already knew. Whether you are Team ‘Obsession’ or Team ‘Backrooms’, one question remains wide open for debate: which of these two YouTube-born horror films deserves to be remembered as the defining theatrical moment of this extraordinary summer?
