Highest Grossing Movie 2026 Odds: Who Are Film Buffs Backing?

Even prior to the release of Spider-Man: Brand New Day on July 27th, this Marvel film was the heavy favorite to be the highest-grossing of 2026.

This outcome already had an 83% win probability on July 26th, but this has since increased to 93% after the movie smashed a series of Box Office records.

The dominance of Marvel’s fourth Spider-Man film has adversely affected trading volumes in recent weeks. Although the market’s total volume exceeds more than $17.2 million, traders are increasingly looking to hold their existing positions or target alternative contracts.

But is there still value in the highest-grossing film market? If so, what trades can you make to deliver some kind of return?

Spider-Man: Brand New Day Odds – Buy “Yes” Shares and Wait Until Settlement

“Spider-Man: Brand New Day” | “Yes” at 93¢ | 93% Chance

There were obvious signs that Spider-Man: Brand New Day was going to be a huge hit at the Box Office. The trailer amassed over 718 million views in just 24 hours after its launch, for example, while pre-sales peaked above $80 million in the week prior to release.

However, few could have imagined the scale of this film’s initial commercial success. It cleared a record $360.09 million domestically during the opening weekend alone, breaking the previous benchmark set by Avengers: Endgame.

Overall, Spider-Man: Brand New Day has generated over $890 million in US cinemas since its release, and Polymarket will use this domestic data to settle the market. 

At the time of writing, The Odyssey is the second best-performing film stateside, but this has grossed just $565.7 million despite launching two weeks earlier. Marvel’s latest Spider-Man hit is now the second-highest-grossing domestic release ever, and it’s all but certain to top the charts in 2026.

So, where’s the value in this market? Well, “Yes” shares on Spider-Man: Brand New Day are likely to settle at $1.00 on or after December 31st, so buying now at 93¢ can still deliver a secure, 7.5% yield in a little less than three months.

This is an excellent rate of return, and one that outpaces similarly low-risk investment vehicles. The main consideration is whether you have the spare capital to commit for the next 120 days or so, as you won’t have much opportunity to sell prior to the market’s settlement.

Avengers: Doomsday Odds – The Ultimate Longshot – But Could it be a Profitable Trade?

“Avengers: Doomsday” | “Yes” at 6¢ | 6% Chance

If a movie is going to topple the latest Spider-Man hit in this market, it’s likely to be Avengers: Doomsday. This Marvel / Disney collaboration has a scheduled US release date of December 18th, 2026, shortly before Polymarket settles the year’s highest-grossing film.

Of course, it’s highly unlikely that this movie could supersede Spider-Man’s commercial performance in a brief, two-week window. However, the film will benefit from a huge marketing campaign during the fall, while the official trailer generated an impressive 503 million views in just 24 hours after launch. 

Remember, you don’t need Avengers: Doomsday to actually become the highest-grossing film in 2026 for “Yes” shares to deliver a profit. 

You simply require the price to increase amid casual trader sentiment and endless news coverage later in the year, with a range of between 15¢ and 20¢ offering an ideal exit window if you buy now at 6¢ (assuming that you’re able to find a buyer). 

Disney is powered by a huge marketing engine, too, while its end-of-year promotions are particularly effective. So, it’s not impossible for the market dynamics to shift slightly in late Fall, potentially creating a speculative, short-term alternative to Spider-Man: Brand New Day.

The Odyssey Odds – A Former Frontrunner That Now Has Minimal Upside

“The Odyssey” | “Yes” at 0.2¢ | <1% Chance

Christopher Nolan’s The Odyssey hit theaters at the beginning of July. First announced in late 2024, the fantasy action movie had a $250 million budget. Matt Damon starred alongside Anne Hathaway, Robert Pattinson, Tom Holland, and Zendaya. 

This stellar cast combined to create an epic film, which as we’ve touched on, has grossed $565.7 million domestically to become the second-best performing movie so far this year. 

However, it has no realistic chance of toppling Spider-Man: Brand New Day, with the film’s win probability falling to less than 1%. Unlike Avengers: Doomsday, however, the current price of just $0.2¢ has minimal upside and has already peaked, while The Odyssey’s current expansion is focused on global markets.

So, I’d recommend that you avoid this film completely in the Highest Grossing Movie market. However, The Odyssey also features in a number of alternative prediction markets, including “The #1 Searched Movie on Google in 2026” and several Oscars’ categories.

The Last Word – Navigating a Difficult and Restricted Market

Ultimately, Spider-Man: Brand New Day is nailed-on to be the highest-grossing movie in the US in 2026. It has already generated more than $890 million domestically, and now has a 93% chance of topping this market.

While the market continues to offer limited value, how you trade it depends on your capital holdings and appetite for risk. For example, you can currently acquire “Yes” shares in the Spider-Man film at a price of 93¢, so there’s some value in buying now and holding until settlement if you can afford it.

Buying “Yes” shares in the upcoming “Avengers: Doomsday” film at just 6¢ also offers a potential upside, if you’re willing to sell prior to settlement. The film isn’t due to be released until late December, but its price may spike during sustained marketing in the fall.

Whichever contract you chose, be sure to track your positions and all relevant breaking news on a frequent basis. This will help you to make smart decisions, and potentially identify new prediction markets as they’re published on Polymarket!
