The Academy Awards are presented annually by the Academy of Motion Picture Arts and Sciences (AMPAS) to honor outstanding artistic and technical achievements in film. For the 99th Academy Awards in 2027, nominations are scheduled to be announced on January 21, followed by the ceremony on March 14, 2027. This market will resolve according to the listed film that wins the 99th Academy Award for Best Costume Design. If a film is not officially nominated for the Academy Award for Best Costume Design when the 2027 nominees are announced, the corresponding market will immediately resolve to "No". In case of a tie for the winner, this market will resolve in favor of the nominated film whose listed title comes first in alphabetical order. If, for any reason, no winner is declared by June 30, 2027, 11:59 PM ET, this market will resolve to "Other". The primary resolution source for this market will be official information from the Academy Awards and AMPAS, including data from their website (e.g., https://www.oscars.org/) and the live broadcast of the award ceremony; however, a consensus of credible reporting may also be used.
