The Yellowstone universe is expanding once again, and this time, Kayce Dutton is stepping into a brand-new world of law and justice. CBS has officially confirmed that the highly anticipated spinoff, Y: Marshals, will premiere in spring 2026 — giving fans a thrilling new chapter that blends the grit of the Dutton legacy with the high-stakes drama of a U.S. Marshals task force.
When Will Y: Marshals Be Released?
The first season of Y: Marshals will include 13 episodes and is set to debut as part of CBS’s 2025–26 television lineup.
While the exact release date hasn’t been revealed yet, CBS confirmed the show will premiere in spring 2026 as a midseason replacement, airing Sunday nights at 9 p.m. ET.
For streaming fans, the series will also be available on Paramount+ shortly after its network debut, likely by early summer 2026.
Who’s Behind the Series?
Unlike previous entries in the Yellowstone universe, Taylor Sheridan will not serve as the main writer. Instead, he joins the project as an executive producer, marking the first Dutton-related series he hasn’t solely written.
The series will be helmed by showrunner Spencer Hudnut, best known for his work on SEAL Team. Sheridan’s creative fingerprints, however, remain all over the project’s tone and world-building, ensuring Y: Marshals stays faithful to the franchise’s rugged spirit.
Cast: Familiar Faces and New Allies
Returning Yellowstone favorite Luke Grimes leads the cast as Kayce Dutton, who leaves the Yellowstone Ranch behind to take on a new mission. He’ll be joined by:
-
Gil Birmingham as Thomas Rainwater
-
Mo Brings Plenty as Mo
-
Brecken Merrill as Tate Dutton
New cast members include:
-
Arielle Kebbel as Belle
-
Ash Santos as Andrea
-
Tatanka Means as Miles
-
Logan Marshall-Green as Pete Calvin
-
Brett Cullen in an undisclosed role
Notably absent from the confirmed cast list is Kelsey Asbille (Monica Dutton), though Kayce is seen wearing his wedding ring in the teaser — a subtle nod suggesting her presence may still influence his storyline.
Plot: A Cowboy Turned Marshal
In Y: Marshals, Kayce Dutton leaves his family’s ranching empire to join an elite U.S. Marshals unit in Montana. Combining his Navy SEAL past and cowboy instincts, Kayce becomes part of a team that delivers frontier-style justice to the modern West.
The series will explore how Kayce balances his sense of duty, family loyalty, and the psychological weight of violence. In the newly released teaser, Grimes’ Kayce confesses,
“I’m just grappling with some skeletons I’d like to keep in my closet.”
That one line sets the tone for what promises to be a darker, introspective journey through the price of justice — and redemption.
