Well, the Yellowstone universe is adding another branch, and this one comes with a couple of curveballs. Y: Marshals is real, it stars Luke Grimes, and yes, it picks up right after Yellowstone. But there are a few behind-the-scenes wrinkles you should know about before you mark your calendar.
- Where to watch: Y: Marshals is heading to CBS as a CBS original, not Paramount+. Multiple outlets, including TVLine and People, say the new series will air on CBS rather than live on the streamer like 1883 and 1923.
- Premiere: March 1, 2026 on CBS.
- Creative team: Taylor Sheridan is an executive producer but not the writer or showrunner here. Spencer Hudnut is writing the series and running the show, with Sheridan helping develop the story. Hudnut previously worked on CBS' Unforgettable and led Paramount+'s SEAL Team.
- Cast: Luke Grimes returns as Kayce Dutton. Yellowstone vets Gil Birmingham, Brecken Merrill, and Mo Brings Plenty are onboard as series regulars, per Deadline. They are joined by Arielle Kebbel, Ash Santos, and Tatanka Means.
- What it is: A direct continuation for Kayce. He leaves ranch life behind and joins an elite unit within the U.S. Marshals, bringing that ex-Navy SEAL and cowboy skill set to crime-fighting in Montana.
- Franchise status: Yellowstone wrapped in 2024, but the brand keeps spinning out. Alongside Y: Marshals, reports from The Week say more projects on the board include The Madison, The Dutton Ranch, and 1944. For context, Yellowstone premiered June 20, 2018; 1883 on December 19, 2021; and 1923 on December 18, 2022.
- Streaming note: Yellowstone and the existing spin-offs are on Paramount+. Y: Marshals is the outlier on CBS.
The CBS move is the twist
Given how the recent spin-offs have lived on Paramount+, moving a series with a giant 'Y' in the title to CBS is a notable pivot. The upside: a full broadcast push. The downside for some: it is not on Paramount+ at launch, which is where the other spin-offs live. People and TVLine both frame it as a CBS original from the start.
Who is steering this thing
If you were hoping for pure Sheridan on the page, temper expectations. Sheridan is on the EP list and is reportedly helping develop the show, but Spencer Hudnut is writing and showrunning. Hudnut cut his teeth on CBS' Unforgettable and really made a name with SEAL Team on Paramount+, which fits the law-and-order-meets-military skill set this premise needs.
The cast: familiar faces and a few new ones
Luke Grimes is back in the saddle as Kayce Dutton. Deadline says Yellowstone stalwarts Gil Birmingham, Brecken Merrill, and Mo Brings Plenty are series regulars here, which should help keep the DNA intact. New additions include Arielle Kebbel, Ash Santos, and Tatanka Means.
So what is Y: Marshals actually about?
It picks up right after Yellowstone, with Kayce moving off the ranch and into a badge. He joins an elite U.S. Marshals unit, applying his Navy SEAL background and cowboy instincts to some very Montana problems. Expect action, expect moral knots, and expect the personal fallout that comes with the job.
'Ex-Navy SEAL Kayce Dutton leaves Yellowstone Ranch to join U.S. Marshals, using his cowboy and military skills to fight crime in Montana while dealing with family ties and the mental toll of law enforcement.'
Where this fits in the bigger Yellowstone picture
Yellowstone proper bowed in 2018 and finished in 2024. 1883 landed in late 2021 and 1923 in late 2022, both on Paramount+. Now the next wave is taking shape: Y: Marshals on CBS in 2026, with The Madison, The Dutton Ranch, and 1944 also in development per The Week. Translation: the brand is not slowing down, it is just spreading out.
Bottom line
Kayce trading the ranch for the Marshals could actually be a clean way to reboot the character without rehashing old Yellowstone drama. The network switch is unexpected, Sheridan stepping back from writing will worry some fans, and yet the premise plus Hudnut's action-drama chops make sense. Circle March 1, 2026.
