Highest grossing movie in 2026?

Platform comparison

Market context

The real-world event this market tracks is simply which film earns the most money in US cinemas during 2026, measured strictly by domestic calendar gross. A YES share represents a bet that a specific film, such as *Spider-Man: Brand New Day*, will be the top earner; a NO share means you believe it will not win. Currently, the crowd assigns a 0% chance to the YES outcome, suggesting traders are either undecided on the frontrunner or believe the leading candidate has not yet been confirmed by the market.

Historically, 2026’s box office is already dominated by *The Super Mario Galaxy Movie*, which has earned over $1 billion worldwide and $428.8 million domestically, making it the current number one [1][2]. However, the market’s 0% probability for the YES outcome likely reflects that the frontrunner for the specific title “Highest grossing movie in 2026?” is *Spider-Man: Brand New Day*, which holds a 77% trader consensus due to its prime July 31 release slot and strong franchise draw [3]. Comparable summer releases like *Toy Story 5* face crowded competition, meaning the final winner remains fluid until late-year data solidifies the rankings [2].

Traders should monitor official release date confirmations, trailer reception, and weekly domestic box office charts, particularly as the summer season peaks. The enduring global appeal of the Tom Holland-led Spider-Man franchise and fresh marketing momentum from a recently released trailer spotlighting high-profile cameos are key catalysts [3]. Any delays to the July 31 launch or negative audience scores could shift the frontrunner to *Toy Story 5*, which benefits from Pixar’s reliable family audience and its June 19 release [3]. Final resolution depends on Box Office Mojo data after 31 December 2026, with an alphabetical tie-breaker if totals match exactly [1].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
