The television adaptation of Stephen King novel The Institute will return for its second season on MGM+ in autumn 2026, according to a report by Screen Rant.

The upcoming season was officially confirmed in a television preview for autumn 2026 compiled by Kara Hedash. The streaming platform MGM+, which is available through Amazon Prime Video, has not yet announced an exact premiere date.

Story details and finale setup
The science fiction thriller adapts the 2019 Stephen King novel of the same name. Created and written by Benjamin Cavell, the series is executive produced by King and directed by From director Jack Bender.
The narrative follows a group of children and teenagers with supernatural powers who are abducted and subjected to experimental tests inside a secretive facility called The Institute.
Although the eight episodes of the first season covered the main story of King's book, key changes in the season finale left room to explore what happens next to Luke, Tim, and the other survivors after the destruction of the facility.
Production timeline and Stephen King universe
Season one completed its initial broadcast run in July 2025, and MGM+ officially ordered a second season the following month. Filming on season two wrapped in June 2026, ensuring the episodes were finished in time for a release before winter.
The premiere follows a busy period for screen adaptations of King's books in 2025. That year saw the theatrical releases of feature films The Long Walk, The Monkey, and The Running Man, alongside the television debuts of IT: Welcome to Derry on HBO Max and season one of The Institute on MGM+.
