Market context
Polymarket is pricing this contract at **3% YES**, which is a very low implied chance for a domestic opening weekend that lands in the highest “even higher” strike band and is settled in **USDC** on **Polygon** through conditional tokens. For a trader, that means the market is effectively assigning only a small probability to the film clearing the upper bracket once The Numbers posts final three-day grosses for **31 July to 2 August 2026**.
The comparison set matters because the public tracking is already clustered around blockbuster territory, but not uniformly at the very top. Recent box office reporting has put domestic opening forecasts anywhere from **$180 million to $190 million** at the conservative end, through **$230 million to $250 million**, and up to **$260 million to $280 million**, with some analysts even floating **$300 million-plus**.[2][3][4][6][7] That range sits below the **$260 million** domestic opening of *Spider-Man: No Way Home*, so a 3% contract price implies the crowd sees the extreme upside as possible but still unlikely relative to the consensus band.[2][4]
The main catalysts to watch are not creative reviews but hard execution variables: final ticket sales cadence, premium-format availability, and any late changes to screen allocation. Sony’s own guidance has been described as more cautious at **$190 million to $195 million**, while the film’s rollout is being shaped by the reported **IMAX exclusion** on opening weekend because *The Odyssey* holds that format exclusively.[2][5][7] If the weekend walk-up stays strong and box office services continue lifting forecasts, the probability on Polymarket can reprice quickly before the opening weekend settles into the The Numbers figures the market uses for resolution.
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
