Insidious Prequel Rotten Tomatoes Score Still Undefined as Market Wagers

Traders are pricing a 61.5% chance the film beats its predecessors' critic scores, even as Rotten Tomatoes lists zero reviews.

A Kalshi prediction market that asks whether the upcoming horror film Insidious: Out of the Further will clear a specific Rotten Tomatoes Tomatometer score implied a 44.5% probability as of Aug. 1, even though the review-aggregation platform has not yet published a single critic or audience rating for the movie. The market, which opened weeks before the film's wide release, has seen the probability drop 49 percentage points over the past 24 hours on $844 in volume, reflecting uncertainty about whether the movie will meet the strike threshold once reviews begin appearing.

Rotten Tomatoes' listing for Insidious: Out of the Further shows zero verified critic reviews on the Tomatometer and zero verified audience ratings on the Popcornmeter, a fact that leaves the market's outcome entirely unresolved. The franchise's critical track record provides a historical range: the original Insidious (2011) holds a 66% Tomatometer from 175 reviews, while the most recent installment, Insidious: The Red Door (2023), sits at 39% from 119 reviews. Rotten Tomatoes' own franchise ranking places the original as the highest-rated entry in the series, but the variance between films makes extrapolating a precise score for the new prequel difficult.

Market rules state that the score will be determined on the Monday after the film's wide release at 10:00 a.m. ET, meaning the 44.5% implied probability reflects speculative positioning ahead of that date rather than a response to any concrete critical or audience data. The 24-hour move of minus 49 points suggests traders have recently shifted toward pessimism, perhaps on expectations that the prequel will underperform relative to the original, but without any published reviews to confirm or refute that thesis.

Until Rotten Tomatoes begins aggregating reviews after the theatrical rollout, the market will remain a bet on an unknowable outcome. Investors and horror fans alike are left to weigh franchise history against the inherent uncertainty of a prerelease prediction, with the next meaningful data point arriving only with the first wave of critic and audience ratings.
