We examine the big movers and picks on the highest-grossing movie prediction market.
At a Glance:
- "Spider-Man: Brand New Day" is the favorite, with a 56% chance of taking top spot

- "Toy Story 5" could be the sensible value pick if you follow the Taylor Swift news
How the highest-grossing movie prediction market works
The major prediction markets like Polymarket facilitate share trades on which film will top the box office this year.
You purchase shares on whether you think the prediction is right or wrong. For example, a buy on ‘Yes’ for "Spider-Man: Brand New Day" to be the box office winner costs $0.57 per share.
All shares in this market will resolve at $1 on Dec. 31. That means you’d profit $0.43 per share if your spidey sense proves right.
Alternatively, you can go the other way and buy shares in ‘No,’ that the film won’t be the highest-grossing of 2026. Therefore, a ‘No’ share on "Spider-Man: Brand New Day" costs $0.43, with a profit of $0.57 per share minus fees.
Essentially, you are trading against others on this market and their expertise (or lack thereof). The markets work differently from online sports betting sites, where the price is determined by a central odds compiler.
2026 box office frontrunners
Let’s examine the big picks for the box office bonanza in 2026.
"Spider-Man: Brand New Day": ‘Yes’ @ $0.57
Spider-Man’s newest adventure is by far and away the prediction market leader. It’s the first MCU release in a while to star the “old” cast. Tom Holland appears in "Spider-Man: Brand New Day," donning the skintight suit once again.
The movie has the advantage of a summer release, giving it time to generate both buzz and dollars before Christmas. And then there’s one more Marvel movie to follow shortly after.
However, the market on Spidey rose from $0.44 to $0.77 before settling down in the 50s. That could have been savvy traders selling their positions by exploiting Marvel hype.
"Avengers: Doomsday": ‘Yes’ @ $0.18
Marvel fans sick of a series of mediocre releases will be licking their lips at the release of "Avengers: Doomsday." Many of the familiar MCU characters are returning, including Robert Downey Jr. (this time playing the bad guy instead of the hero).
"Avengers: Doomsday" is released the same day as "Dune: Part 3." However, even “Dunesday” will be too late to rack up enough receipts for either film before year-end.
"Toy Story 5": 'Yes’ @ $0.17
Woody, Buzz, et al return in "Toy Story 5," the other big summer family release. The big social media buzz (pardon the pun) centers around Taylor Swift.
The singer just dropped her newest single, "I Knew It, I Knew You," the theme song from the movie. Could Taylor fans help "Toy Story 5" at the box office?
The pick of the value trades
The "Super Mario Galaxy Movie" benefited from a spring 2026 release. With little competition in the family market, it surged to No. 1 at the U.S. box office and has grossed nearly $1 billion to date.
That’s all well and good, but the Mario movie may have shot its bolt. With Marvel looming over the horizon, the $0.04 'Yes' share for Mario represents thin value.
