The release of the first wave of critic reviews for DC Studios' Supergirl on June 24, 2026, caused a significant upward repricing in prediction markets tracking the film's final Rotten Tomatoes score. Contracts on the Kalshi exchange for the film’s score to finish “Above 55” jumped to 79% in the session on June 25, 2026, a 56-percentage-point spike from 27% prior to the review embargo lifting. The move signals traders are rapidly aligning expectations with the film's real-time score, which has stabilized in the high-50s based on nearly 200 initial reviews.
The broad repricing suggests a market consensus forming around a "Rotten" but not disastrous critical reception. Probability shifted upward across all contracts in the 35% to 65% range, indicating that while a "Certified Fresh" rating (above 75%) is seen as highly unlikely, the worst-case scenarios of a critical flop have been largely priced out. The film currently holds a 58% Tomatometer score from 197 reviews.
Distribution Analysis
The shift was uniformly positive, with no contracts declining in value. The most significant gains and highest trading volumes were concentrated in the outcomes directly surrounding the film's current score, particularly in the 50% to 60% range.

What's Driving the Shift
The repricing appears directly tied to the availability of hard data following the lift of the film's review embargo.
Initial Score Publication: The primary driver is the establishment of an official Tomatometer score. Before the embargo lifted, the market was trading on speculation and marketing materials. The current score, which has fluctuated between 57% and 62% as reviews were tallied, provided a firm anchor for market odds, resolving much of the pre-release uncertainty.
Mixed-to-Positive Reception for Alcock: While overall reviews describe the film as "uneven" and "divisive," a consistent throughline is praise for star Milly Alcock's performance as Kara Zor-El. Multiple reviews highlight her as a standout, with MovieWeb calling her "fantastic" and Rotten Tomatoes' own summary noting she "stands out in an uneven entry." This critical support for the lead performance likely prevents the score from collapsing into lower tiers, supporting a final score in the 50-65% range.
Market Context
This market event represents a classic transition from uncertainty to certainty. The 56-point jump in the "Above 55" contract reflects the removal of downside risk that was previously priced in. Traders are no longer betting on what the score could be, but rather on how the currently established 58% score will evolve as the final few hundred reviews are logged.
The film's reception is being closely watched as the second theatrical release in the rebooted DC Universe (DCU), following 2025's Superman. Critics have noted that Supergirl is far more divisive than its predecessor, which may explain why market odds for a "Certified Fresh" rating (requiring a score of 75% or higher) remain at just 1%. The current pricing implies the market expects Supergirl to land in a similar critical tier as DCEU entries like Wonder Woman 1984 (57%) and Man of Steel (56%).
What to Watch
The key variable for this market is the trajectory of the Tomatometer score as more reviews are added leading up to and following the film's wide release on June 26, 2026. The score can still move several percentage points in either direction. The market will resolve based on the official score listed on Rotten Tomatoes on its closing date of June 29, 2026.
