Kathryn Newton's return as Cassie Lang in Avengers: Doomsday
Avengers: Doomsday: Cast
Kalshi prices this Kathryn Newton as Cassie Lang? at 97%. The reporting broadly agrees.
Kathryn Newton, who debuted as Cassie Lang in 2023's Ant-Man and the Wasp: Quantumania, is widely expected to reprise the role in Avengers: Doomsday, Marvel's next major ensemble film slated for a December release. A recent trailer for the film hints at a darker storyline involving the Ant-Man corner of the franchise, and Newton herself addressed the Doomsday project in an interview this month tied to her new shark horror film. Traders put the likelihood of her return at 97%, a level that broadly tracks the coverage, which has treated her participation as a given rather than an open question. The market is set to resolve on January 1, 2028.
Background
Newton took over the role of Cassie Lang from Emma Fuhrmann, who played an older version of the character briefly in Avengers: Endgame. Newton's Cassie was central to Quantumania, where she helped catalyze the family's journey into the Quantum Realm and crossed paths with Jonathan Majors' Kang the Conqueror. Avengers: Doomsday, directed by the Russo brothers, is positioned as a major pivot point for the Multiverse Saga, with the trailer suggesting the Ant-Man storyline takes a darker turn. The specific question at hand is whether Newton is confirmed as Cassie Lang in the Doomsday cast, with resolution set for January 1, 2028.
The precedent
- Kathryn Newton replaced Emma Fuhrmann as Cassie Lang beginning with Ant-Man and the Wasp: Quantumania in 2023, after Fuhrmann had played the role in a brief Endgame scene.
- The Russos, who direct Avengers: Doomsday, previously directed Avengers: Infinity War and Avengers: Endgame, the two highest-grossing MCU films.

What to watch
Marvel has not released an official full cast list for Avengers: Doomsday, and the December release window means marketing materials and press tours will ramp up in the months ahead. Newton's own comments in recent interviews, alongside any official announcement from Marvel Studios, would settle the question well before the January 2028 resolution deadline.
