Blumhouse Atomic Monster Hits $1 Billion Box Office Milestone in 2026

Horror has quietly emerged as one of the biggest box office stories of 2026, with Blumhouse Atomic Monster leading the charge. Jason Blum and James Wan’s combined studio has demonstrated that low-budget horror films can still dominate theaters filled with more expensive franchise offerings.

This success has been building over the months, fueled by a series of low-budget horror titles that have consistently exceeded expectations. From a chilling liminal-space thriller to a possessed-teen horror, the studio’s lineup has thrived while many larger studio releases have struggled to find their audience.

Now, Blumhouse Atomic Monster has reached a significant milestone. Their horror films, including ‘Obsession,’ ‘Backrooms,’ ‘Insidious: Out of the Further,’ and ‘Lee Cronin’s The Mummy,’ have collectively grossed over $1 billion at the global box office this year. The studio surpassed this mark last weekend, largely thanks to the $60 million global opening of ‘Insidious: Out of the Further,’ marking their fourth horror release of 2026.

‘Obsession’ has become the standout hit among these films. It has surpassed $501.6 million globally, making it the highest-grossing release in Blumhouse Atomic Monster’s history, as well as for Focus Features, surpassing ‘Conjuring: The Last Rites,’ which previously held the record at $499.2 million. Written and directed by 26-year-old Curry Barker, ‘Obsession’ was produced for just $750,000, yielding over 650 times its original budget.

Such returns place ‘Obsession’ in an elite category. It is now the lowest-budget horror film to top the North American box office since ‘Paranormal Activity’ in 2009, a notable comparison given Blum’s history with that franchise. Additionally, the film has become the highest-grossing movie ever acquired from a film festival by a distributor, according to Deadline.

‘Obsession’ is not alone in achieving this billion-dollar milestone. ‘Backrooms,’ adapted by 20-year-old director Kane Parsons from his own YouTube creepypasta series, has grossed $396.5 million worldwide, making it A24’s highest-grossing release ever. Meanwhile, ‘Lee Cronin’s The Mummy’ has contributed $90.5 million to the total, rounding out a slate of four films that were produced for just $50.75 million combined, resulting in a roughly 20-times return on investment within the first eight months of the year.

This marks the second time Blumhouse Atomic Monster has crossed the billion-dollar threshold since the two companies merged in 2024. Including their combined grosses prior to the merger, this is actually the third time in four years that Blumhouse and Atomic Monster titles have collectively surpassed $1 billion in a single year, following a strong 2023 that featured hits like ‘Five Nights at Freddy’s,’ ‘M3GAN,’ and ‘The Exorcist: Believer.’

This trend reflects a broader strategy that has consistently paid off for the studio: support young, unique filmmakers with limited budgets and allow word of mouth to drive success. With ‘Insidious: Out of the Further’ still in theaters and more genre films reportedly on the horizon, Blumhouse Atomic Monster appears set to maintain this successful formula throughout the remainder of the year.

For a genre often overlooked in favor of blockbuster franchises, this billion-dollar achievement on modest budgets underscores the profitability of horror when it resonates with audiences.
