Kathryn Newton as Cassie Lang?

Avengers: Doomsday is a Marvel film scheduled to release on December, 18, 2026. This market will resolve to "Yes" if the listed actor playing the listed character appears in Avengers: Doomsday. Otherwise, this market will resolve to "No". This market will resolve upon announcement of casting, regardless of if the film is delayed, cancelled, or otherwise fails to be released. If no casting is announced, this market will resolve upon footage of the domestic theatrical cut of the film. If multiple people are cast for the same role, the listed individual being among the cast list for the relevant character will be sufficient to qualify this market towards a "Yes" resolution. If no casting is announced and Avengers: Doomsday is definitively cancelled or fails to be released by June 30, 2027, 11:59PM ET, this market will resolve to "No". This market will resolve based on official announcements from Marvel or Warner Bros., the domestic theatrical cut of Avengers: Doomsday, or a consensus of credible reporting.
