A brand new day has finally arrived for one of our favorite superheroes. The latest installment hit US theaters on 31 July, and fans have been speculating on whether this title has what it takes to blow other MCU creations out of the water.
Now, the verdict is in. Spider-Man: Brand New Day has settled at a final Tomatometer score of 90%, officially closing the Kalshi market and determing who won and lost.
Spider-Man: Brand New Day Rotten Tomatoes Score Market Resolved
Spiderman: Brand New Day went straight in with a 90% Rotten Tomatoes score, which quickly rose to 91% before later dropping back down to 90%.
By the time the market closed, there was over $7,600,000 in total trading volume, but many lost out as the score settled just below the 91% point that had been predicted a few days prior.

Key Takeaways:
- The Market Favorite: Kalshi traders favored a strong critical response, with the "Above 89" score contract priced at 99¢ (99% implied probability) before the market closed.
- Key Threshold: "Above 90" contracts had been priced at 59¢ (59% implied probability), with high levels of confidence in the movie's score matching that of previous MCU Spider-Man movies, but that price dropped right down to 2¢ by August 3.
- Higher Brackets Collapse: The "Above 91" bracket had been sitting at a 28% 'Yes' chance, with a question mark over whether it could move past 91%. Those contracts too collapsed hours before resolution.
Spider-Man: Brand New Day Rotten Tomatoes Score: Traders Were Right To Expect Rating of at Least 89%

Traders who held 'Yes' contracts up to Above 89 collected the full $1.00 payout per contract. Those buying 'Yes' on Above 89 at the last minute would’ve paid 99¢ and earned a 1% quick profit, but traders who picked up contracts at those early, lower prices saw significantly higher returns.
The final score hit exactly 90%, so it was not above 90%. Traders who held 'No' on "Above 90" through "Above 94" swept full $1.00 payouts per contract.
Kalshi’s crowd-sourced final forecast closed at 89.5%, missing the actual 90% mark by a hair. Traders who hedged around the 89–90 range captured the sweet spot of this $7.6M market.
Pre-embargo speculation had briefly pushed expectation forecasts up near 92.4%, but traders who picked up ‘Yes’ contracts for “Above 90” or higher lost out. Traders holding ‘No' on “Above 89” and lower also lost their full stakes.
This market is now closed, but there are plenty more related markets to choose from on Kalshi right now. The most pressing of which is, of course, the Avengers: Doomsday prediction markets!
Spider-Man: Brand New Day Value Picks: The Biggest Winners
If you’re looking for profits on a board like this one, you need to separate realistic probabilities from fan sentiment. The crowd was eager to back blockbuster success on this one, but instances where prices really differed from critic opinions gave traders the best opportunities to profit.
Top Pick 1 | 'Yes' Above 89% (99¢)
Resolved: ✅ ’Yes’ Traders Won
The Spiderman: Brand New Day Rotten Tomatoes score went straight in at 90% as the first user reviews came in, before rising to 91%.
However, "Above 89" is currently trading at 99%. That could be down to more mediocre reviews (not all critics loved it).
Kalshi traders now forecast a 90% rating on the Tomatometer. That's about where our analysis lies, and it's unlikely the score will rise any higher at this point.
Destin Daniel Cretton already has proven success with previous MCU titles, (Shang-Chi and the Legend of the Ten Rings, which stands at 92% on Rotten Tomatoes) so the risk level on this one is low.
Top Pick 2 | 'No' Above 92% (97¢)
Resolved: ✅ ’Yes’ Traders Won
Traders can pick up 'No' contracts for "Above 92" for 97¢ at the moment.
Pushing past 92% has always been difficult for superhero movies, so it’s unlikely that the latest Spider-Man title will get there once all the reviews are taken into account.
The ‘No’ is a good option, providing protection from reviews that might mark the film down for its runtime or darker themes.
Top Pick 3 | 'Yes' Above 87% (99¢)
Resolved: ✅ ’Yes’ Traders Won
Now at 99¢ (up from 83¢), the "Above 87" 'Yes' has already proven to be a good safety buffer for traders wanting to avoid too much risk.
Even if the film’s reception is slightly mixed compared to No Way Home (93%), every other mainline MCU Spider-Man film has scored above 90%, so it’s highly unlikely that this one won’t.
Traders Look Ahead to Spider-Man: Beyond the Spider-Verse
Traders who analyzed Sony's Spider-Man slate are also active on the release timeline for animated follow-ups.
The new market "When will the official trailer for Spider-Man: Beyond the Spider-Verse be released?" has now generated over $21,000 in trading volume, with contracts currently pricing a trailer release before December 1, 2026, at 56% ('Yes' 56¢ / 'No' 52¢).
The price of a trailer before April 1, 2027, jumps to 86% ('Yes' 93¢ / 'No' 15¢).
Tips for Trading Rotten Tomatoes Film Review Markets on Kalshi
Kalshi regularly launches Rotten Tomatoes score markets for the biggest new film releases.
Recently, traders correctly predicted a 95% tomato score for The Odyssey, and we’ve already got a number of other markets available for upcoming releases over the summer.
If you’re thinking of putting money on how the next big blockbuster goes down, here are a few tips.
- Watch the News Cycle: Keep a close watch for initial social media embargo lifts and full review drops from major trades like Variety, The Hollywood Reporter, and IndieWire.
- Think Flip Opportunities: Consider taking early 'Yes' positions on higher strike brackets (e.g., 92 or 95) during the initial wave of glowing review reactions, then selling to lock in profits before additional reviews dilute the overall score.
- Consider Market Volatility: Binary markets like these fluctuate all the time, but the biggest changes occur while the review count is low. Early 100% scores quickly drop as more critics file reviews.
