The embargo for the highly anticipated horror movie Backrooms ends tomorrow, but Kalshi traders are already trying to predict how it will do with critics.

The market for the movie’s Rotten Tomatoes score predicts it will have a score of 81.3% on the Tomatometer on the Monday following the film’s release.

The story behind Backrooms

The movie is based on a long-running YouTube series created by filmmaker Kane Parsons who also co-wrote and directed the movie for A24. He’s the youngest filmmaker to helm a film for the studio at age 20. The film is also produced by horror filmmaker James Wan and Stranger Things producer Shawn Levy.

According to Vanity Fair, Chiwetel Ejiofor stars as a furniture store owner who discovers a portal in his store that leads to an anomalous dimension consisting of a never-ending series of blank rooms that seem to defy the laws of logic and space. His therapist, played by Renate Reinsve, is drawn into the store owner’s investigation of the bizarre space.

The “backrooms” concept started as a creepypasta thread on communities like 4chan. Parsons started making videos exploring the strange urban legend concept in videos on his YouTube channel under the name “kane pixels”, using the VFX graphics suite Blender to create his strange and unnerving videos.

Parsons was just 16 years old when he started the YouTube series, but he almost immediately started receiving interest from movie studios about expanding his YouTube videos and stories to the big screen. He signed a deal with A24 when he was just 19 while applying for college.

The Backrooms movie

The film appears to be an extension of the lore created by the creepypasta and Parsons’ Youtube channel.

Parsons told Deadline Hollywood in an interview that he used the same software for creating his YouTube videos to build the concepts for the sets in the movie.

“I think I’m personally very, very satisfied with what we did,” Parsons said. “Without saying too much, you can see it in what we’ve released with the trailer so far.”

The takeaway:

Kalshi markets now predict

  • Backrooms’ Rotten Tomatoes score: 81.3%
