Which movie has biggest opening weekend in 2026?

Platform comparison

Market context

The real-world event this market tracks is which film earns the most money at US cinemas during its first three days of release in 2026. A YES share pays out if the market resolves to the top-grossing opening weekend, while a NO share pays out if any other film holds that title. Currently, the crowd assigns a 0% chance to YES, suggesting traders believe the market has already settled on a winner or that the resolution criteria will not be met by a new contender.

Historical 2026 data frames this near-zero probability. Christopher Nolan’s *The Odyssey* opened to $124.5 million in July, while *Toy Story 5* previously set the year’s record with $160 million domestically in June [2][5]. Although *Project Hail Mary* claimed the biggest opening earlier in the year at $80.6 million, it was quickly surpassed [1]. With *The Super Mario Galaxy Movie* reportedly grossing $372 million globally (though domestic figures remain unconfirmed in trade sources), the domestic leaderboard appears locked, leaving little room for a new record-breaker to emerge late in the year [3][8].

Traders should monitor final domestic confirmations for *The Super Mario Galaxy Movie* and any surprise late-year releases, as the market resolves only on finalised 3-day domestic figures from The Numbers, not studio estimates [4]. The settlement window closes on 31 December 2026, meaning any film releasing in November or December must outperform *Toy Story 5*’s $160 million to change the outcome. No major December 2026 releases have yet announced opening weekend projections that threaten this threshold, according to recent industry schedules [4].

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
