As of March 2026, the official release date for Citadel Season 2 has not yet been announced by Amazon Prime Video. While Season 2 was confirmed and production is underway, a specific premiere date is still pending. The first season premiered in April 2023, and it's common for high-production-value series like Citadel to have a significant gap between seasons due to extensive filming, post-production, and special effects work.
Reports indicate that filming for Season 2 began in late 2024 or early 2025, with Joe Russo returning to direct. David Weil is expected to continue as showrunner. Given the scale of the series, it's reasonable to anticipate a release sometime in late 2026 or early 2027, but this is an estimation based on typical production timelines, not an official confirmation.
Pro tip: To stay updated on the official release date, keep an eye on Amazon Prime Video's official social media channels and press releases. They will be the first to announce it once a date is locked in.
