Prime Video has had a massive year so far, with hits like The Wrecking Crew and The Bluff dominating the streaming conversation. But the platform's biggest bet yet is back: Citadel, the sleek, globe-trotting spy thriller that reportedly cost $300 million for its first season, has returned for Season 2—and it's already storming the charts.
Season 2 of Citadel dropped all episodes on Prime Video in May 2026, and within hours, the series shot to the #1 spot on streaming rankings around the world. The show stars Richard Madden as Kane, Priyanka Chopra Jonas as Nadia, and Stanley Tucci as Bernard, who reunite to recruit a new team of operatives for a perilous mission. With its high-octane action, near-sci-fi tech, and international intrigue, Citadel continues to be one of the most expensive—and most-watched—series on the platform.

Will There Be a 'Citadel' Season 3?
Prime Video has not yet officially renewed Citadel for a third season. Given the show's massive budget—reports suggest the first season alone cost around $300 million—the streamer will likely need Season 2 to perform exceptionally well to justify another installment. Early streaming numbers are promising, but only time will tell if the series gets the green light for more missions.
For now, fans can dive into all the twists and turns of Season 2. The series also joins Prime Video's lineup of expensive originals, including The Lord of the Rings: The Rings of Power, which is estimated to cost over $1 billion by its end. While Citadel may not have that kind of budget, its slick production and star power make it a must-watch for spy thriller enthusiasts.
