Market context
Sony Pictures will release "Spider-Man: Brand New Day" on 31 July 2026, with this market measuring its domestic box office performance through the end of August. The settlement relies on finalised daily figures from The Numbers rather than studio estimates, covering the film's opening month and initial August performance. The 81% crowd probability suggests traders expect the film to clear the higher strike thresholds during this 32-day window.
Marvel Studios' Spider-Man films have historically demonstrated strong front-loaded domestic performance. "Spider-Man: No Way Home" (2021) earned £1.92bn globally, with roughly 40% of that total arriving domestically in its opening month. "Spider-Man: Across the Spider-Verse" (2023) grossed £690m worldwide, though animated entries typically show different pacing than live-action releases. The current implied probability reflects confidence in a comparable opening-month performance, though the exact strike brackets remain undisclosed in available market documentation.
Key variables include the film's critical reception upon release, competition from other summer tentpoles, and any marketing momentum shifts in the weeks before launch. Sony's promotional calendar and early tracking data will emerge in June 2026. International performance often influences domestic legs, particularly for superhero properties with global appeal. The settlement mechanism's tie-breaking rule—resolving to the higher bracket when figures fall exactly between thresholds—slightly favours YES positions at boundary points, a technical detail traders should note when evaluating marginal outcomes.

FAQ
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
