Steven Spielberg’s upcoming sci-fi thriller Disclosure Day is getting a box office forecast that lands in a cautious middle ground. Early tracking points to a domestic opening weekend of $45 million to $59 million, a range that suggests interest is present but not yet strong enough to signal a breakout.
The film centers on Emily Blunt as Margaret Fairchild, a Kansas City meteorologist who suddenly begins speaking in an unknown alien language. That strange event triggers panic over first contact and pulls the story into a broader conflict involving government control, social manipulation, and a whistleblower named Daniel Kellner, played by Josh O’Connor.
A moderate opening in a crowded market
The projection comes from a May 15 analysis by BoxOfficeTheory, and it is still early enough for the numbers to change. Disclosure Day has about a month left to build momentum, but the current estimate already places it below several other 2026 studio titles.
Those comparisons include Project Hail Mary at $80 million, Michael at $97 million, Scream 7 at $63 million, and The Devil Wears Prada 2 at $76 million. The forecast also sits in the neighborhood of films with very different outcomes, such as Pixar’s Hoppers, which opened to $45 million before finishing with $371 million worldwide.
Budget uncertainty adds to the pressure
One major unknown is the film’s budget, which has not been confirmed. That matters because Spielberg’s large-scale productions have carried sizable costs in the past, including Ready Player One at $175 million, West Side Story at $100 million, and Indiana Jones and the Kingdom of the Crystal Skull at $185 million.
If Disclosure Day ends up in that range, the film would need a substantial run to reach profitability, since a common break-even benchmark is about 2.5 times the budget. That challenge becomes more significant if the opening lands near the lower end of the current forecast.
Spielberg and Blunt could still lift the ceiling
Despite the cautious outlook, the report still sees upside from Spielberg and Blunt as familiar names with broad audience appeal. It also describes Disclosure Day as Spielberg’s “most commercially accessible release for multiple demographics since his 2018 adaptation of Ready Player One.”
There are also signs that premium formats and early presales could help the film’s first weekend. Sales begin on May 27, and strong demand in those channels could push the opening higher than current tracking suggests.
Original sci-fi faces a familiar hurdle
Even with those positives, the film is still an original story without major source material behind it, and that often limits opening weekend potential. Box office tracking has long shown that non-franchise projects usually settle into a narrower launch range unless reviews, buzz, or event-level spectacle change the picture.
Disclosure Day also has to navigate a crowded June release window. It opens on June 12, then faces Toy Story 5 a week later on June 19, followed by Supergirl on June 26 and Minions & Monsters on July 1.
That schedule may help it stand out as a PG-13 sci-fi drama aimed at older viewers, but it also gives casual moviegoers plenty of alternatives. For the film to avoid getting lost in the shuffle, it will likely need strong marketing, positive reactions from critics and audiences, and enough word of mouth to keep interest building after opening weekend.
Spielberg also previewed new footage at ComicCon in April, showing Blunt and O’Connor’s characters in a tense escape that includes a farmhouse crash and a sequence on top of a train. The footage reinforces the film’s mix of alien mystery and human pursuit, which may prove central to whether Disclosure Day can move beyond an average forecast and find a bigger audience.
