When the review embargo for Mortal Kombat II lifted on May 6, the critical verdict came in clearer than most prediction market traders had dared to hope. The sequel landed a 77% on Rotten Tomatoes, giving it a "Fresh" rating, historic for the franchise, and well above what Kalshi's own crowd had forecasted just weeks earlier.
For anyone trading the Mortal Kombat II Rotten Tomatoes market on Kalshi or any other top prediction market apps, the final resolution told a fascinating story about prediction markets, film criticism, and the strange art of forecasting Hollywood.

What Is the Mortal Kombat II Rotten Tomatoes Kalshi Market?
Kalshi's Rotten Tomatoes prediction markets, trading under the KXRT-MOR ticker, let users bet real money on what a film's RT critics score will be on the Monday after opening weekend. The Mortal Kombat II market asked a deceptively simple question: which score bracket would the sequel land in?
Kalshi launched these markets earlier this year, and they quickly became some of the most active and liquid on the platform. The concept is intuitive; everyone has an opinion about movies, and Rotten Tomatoes is the scoreboard the industry watches, but executing a profitable strategy is harder than it looks.
What Kalshi Traders are Saying
As recently as April 30, the Kalshi crowd was decidedly skeptical. The market was pricing Mortal Kombat II at an expected 53% critics' score, squarely in "Rotten" territory, below the 60% threshold Rotten Tomatoes uses to award a "Fresh" designation. The forecasted score had been bouncing between roughly 40% and 57% since tracking began in mid-April, reflecting genuine uncertainty about what critics would do with a franchise built more on nostalgia and fan service than prestige filmmaking.
That skepticism wasn't irrational. The first film in the reboot, 2021's Mortal Kombat, earned a 55% from critics, a Rotten score that made the sequel's production a harder sell.
And the video game adaptation genre has a notoriously poor record with critics. The market was also pricing in the risk that a late review embargo (reportedly May 6, just two days before release) typically signals a studio not eager for early scrutiny.
Why the Market Was Wrong and Why Traders Should Take Note
The "embargo-as-warning-sign" trope burned at least one experienced trader during a similar situation earlier this year. And it burned again here.
The market missed several signals that, in retrospect, pointed toward a stronger-than-expected score:
Fan Screening Buzz
Early audience reactions from advance screenings were notably enthusiastic. Viewers flagged that the sequel had scrapped the polarizing "Arcana" mythology of the first film and leaned harder into the game's tournament structure, exactly what critics of the 2021 film had been asking for.
Karl Urban Owns the Moment
The addition of The Boys star Karl Urban as Johnny Cage gave critics something to actually review. Urban's character, a washed-up, self-aware action star pulled into inter-dimensional kombat, gave the film a comedic through-line that reviewers repeatedly singled out as the sequel's biggest upgrade. Markets' pricing sequels often underweight the impact of a single well-cast new character.
Director Continuity Works
Simon McQuoid returned to direct, and Jeremy Slater took over writing duties with a clear mandate to address the first film's criticisms. Sequels with this kind of deliberate course-correction tend to outperform their predecessor's critical reception more often than markets expect.
The Outcome: A Franchise Record
When the embargo broke, Mortal Kombat II debuted at 77% on Rotten Tomatoes based on 66 reviews, eventually settling around 74–77% as more reviews came in. That makes it not only the highest-rated live-action Mortal Kombat film ever, but the first one to receive a "Fresh" designation, a distinction none of the previous entries (1995's original at 45%, 1997's Annihilation at a catastrophic 4%, or 2021's reboot at 55%) had managed.
Critics were consistent in their praise and their complaints. On the positive side: the fight choreography is better, Karl Urban's Johnny Cage is a genuine delight, and the film actually delivers the Mortal Kombat tournament that the first film famously withheld. On the negative side: the story remains thin, the roster of characters is overwhelming for newcomers, and the film prioritizes fan service over narrative coherence. Empire called it "a lot of dumb fun." RogerEbert.com noted it delivers on its grisly promise whenever the characters stop talking. Variety flagged "dependable action" alongside a "sludgy story."
None of that stopped critics from recommending it, which is ultimately what the Rotten Tomatoes binary measures.
What Traders Can Learn
The KXRT-MOR market illustrates a few things worth noting for anyone trading Kalshi's RT markets:
- Embargoes are noisy signals: A late embargo correlates with bad reviews on average, but the variance is high. Mortal Kombat II is a data point against using it as a decisive factor; the studio may have simply wanted to concentrate the review news cycle close to opening weekend.
- Fan service has a floor: Movies built explicitly for existing fans of a franchise tend to receive a certain baseline of goodwill from critics who at least appreciate craft and commitment. The market may chronically underprice sequels that are clearly improvements on flawed originals.
- Genre discounts are real but overstated: Action films based on video games do underperform prestige fare with critics, but the market was pricing Mortal Kombat II as if it had essentially no chance of going Fresh. That probability was clearly undervalued.
The Bigger Picture
Kalshi's Rotten Tomatoes markets are an interesting experiment in applying prediction market logic to cultural taste. Unlike political or economic events, film criticism involves enough subjectivity that the market can't simply aggregate existing information; it has to forecast human aesthetic judgment. That makes these markets genuinely hard, genuinely fun, and, when they resolve, surprisingly instructive.
Mortal Kombat II opens in theaters on May 8. Box office projections range from $40–55 million domestically for its opening weekend, a number that would easily outpace the original's pandemic-hampered $23 million debut and set the franchise up for a third installment that, per reports, is already in early development.
The critics didn't deliver a flawless victory. But they didn't call a fatality either. For the traders who held the over on this one, that's more than enough.
