Market context
The Odyssey's second weekend domestic box office performance will be tracked through The Numbers' reported figures for the three-day period of 24–26 July 2026. This market captures the film's hold during its opening fortnight, a critical window for determining whether initial audience reception translates into sustained commercial momentum. The settlement relies on finalised data rather than studio estimates, meaning traders must wait for official reporting before resolution occurs.
Second-weekend holds vary dramatically by genre and opening context. Franchise entries and event films typically retain 50–65% of opening weekend grosses, whilst character-driven dramas often drop 40–50%. The current 1% probability suggests the market is pricing in a scenario where The Odyssey underperforms significantly or faces unexpected competition. Historical precedent matters here: films opening in late July face summer fatigue and competing releases, yet established properties often demonstrate resilience. A trader evaluating this programmatically would need to monitor comparable titles' trajectories and cross-reference The Numbers' historical hold patterns against the film's genre classification and production scale.
Catalysts to track include any pre-release tracking data from box office forecasters, competing releases scheduled for the same weekend, and critical reception following the opening. Marketing spend intensity in the second week often signals studio confidence and can influence hold percentages. Traders should establish automated feeds pulling The Numbers' daily figures starting 24 July, as the market's resolution hinges on precise final reporting rather than estimates. Conditional orders tied to opening weekend performance could systematically position for likely second-weekend outcomes.
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.
