Prime Video has confirmed that Citadel will return for season 2 on May 6, 2026, with all seven episodes releasing globally on the same day. The series, produced by Amazon MGM Studios and AGBO, continues its high-stakes espionage storyline with a broader cast and a new global mission.

The show follows operatives Mason Kane, Nadia Sinh and Bernard Orlick—played by Richard Madden, Priyanka Chopra Jonas and Stanley Tucci—as they are drawn back into action after the fall of their agency. Facing a new threat tied to powerful global forces, the trio must assemble a fresh team of agents to stop a conspiracy with far-reaching consequences.

Citadel Season 2 expands the ensemble with additions including Jack Reynor, Matt Berry and Lina El Arabi, alongside returning cast members Lesley Manville and Ashleigh Cummings. The new season builds on the series’ mix of large-scale action and shifting allegiances, with a narrative that leans further into its global scope.

The series premieres exclusively on Prime Video.
