"The Odyssey" Opening Weekend Box Office

Platform comparison

Market context

Christopher Nolan’s epic adaptation of Homer’s *The Odyssey* opens in North American theatres on 17 July, with domestic box office performance over the three-day weekend (17–19 July) determining the outcome of this prediction market. The settlement relies on final, non-estimate figures from The Numbers website, specifically the domestic gross for those dates.

Historical comparables and current tracking suggest a wide but elevated range: projections span $80M–$132M domestically, with averages near $118M and strong IMAX presales supporting higher outcomes [2][3][10]. Polymarket currently assigns 38% to the $105–115M bracket and 36% to >$115M, while CryptoSlate’s snapshot shows >$115M at 47% and $105–115M at 43% [1][5]. This contrasts sharply with the 0% YES implied probability cited in the market prompt, indicating either a data lag or a mismatch between the prompt’s framing and live liquidity. On Kalshi, Betfair, or Smarkets, such a market would typically use decimal odds rather than implied probability, and fee structures vary significantly—Polymarket often charges no maker fees but may impose taker fees, whereas Kalshi requires KYC and applies exchange fees, creating divergent pricing dynamics for identical events.

Traders should monitor final studio estimates released 17–19 July, particularly IMAX and premium large format (PLF) screen contributions, which BoxOfficePro highlights as critical drivers [9]. Any deviation from the $100M–$120M long-range forecast could shift brackets, especially given the rule that exact ties resolve to the higher bracket [9]. Deadline’s $80M–$100M lower-bound projection remains a key risk if audience turnout underperforms relative to presale momentum [2].
