This market will resolve according to how much "Whalefall" Opening Weekend Box Office will gross domestically on its opening weekend. The "Daily Box Office Performance" figures found on the "Box Office" tab on this movie's The Numbers (https://www.the-numbers.com/) page will be used to resolve this market once the values for the 3-day opening weekend (October 16 - 18) are final (i.e., not studio estimates). If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. Please note, this market will resolve according to the The Numbers figures provided under Weekend Box Office Performance for the 3-day weekend (which typically includes Thursday's previews), regardless of whether domestic refers to only the USA, or to USA and Canada, etc. If there is ambiguity as to whether the resolution source's figures are final, this market will remain open until both https://www.boxofficemojo.com/ and https://www.the-numbers.com/ have confirmed their finalized figures. If there is no final data available by October 23, 2026, 11:59 PM ET, another credible resolution source will be chosen.
