- CBS is cooking up a procedural spin-off of Taylor Sheridan’s Yellowstone dubbed Y: Marshals (working title) with Luke Grimes set to reprise his role as Kayce Dutton.
- The new show would join a growing stable of Yellowstone spin-offs which currently include The Madison starring Michelle Pfeiffer, 6666, Dutton Ranch, and more
- A report published by Bloomberg’s Lucas Shaw indicates Y: Marshals will arrive in 2026.
Months after the flagship neo-western series concluded in a rather divisive manner, the Yellowstone universe appears to be on track for yet another expansion – this one, as we’d anticipated, centring on Kayce Dutton (Luke Grimes).
Tentatively titled Y: Marshals, helmed by Spencer Hudnut (SEAL Team), and destined for CBS, according to the official logline, the forthcoming series has Kayce “combining his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty, and the high psychological cost that comes with serving as the last line of defence in the region’s war on violence.”

Grimes previously told Esquire that “there’s always talks of spin-offs,” before affirming his willingness to get onboard. But personally, he didn’t see where it’d go post-season 5B finale.
“Kayce wants to cowboy and be happy with his family. He doesn’t want to kill people anymore. He doesn’t want the weight of a huge mega ranch that isn’t sustainable in today’s times. He wants his little slice of heaven. It’s that simple,” he said (though that’s clearly since changed).
In Yellowstone season 5B, to preserve the land his family had died for across generations, the surviving Dutton son sold the coveted Yellowstone Ranch to Thomas Rainwater and the Broken Rock Reservation for a symbolic price of $1.25 per acre – the price his ancestors paid.
As a gesture of goodwill, the reservation offers him a modest piece of land where he can live in peace with his wife Monica (Kelsey Asbille) and own son Tate (Brecken Merrill), run the ranch at his own leisure, and most importantly, be canonically free for narrative manoeuvring. And/or loose enough to be thaken off the chessboard.
Aside from CBS’ Y: Marshals starring Luke Grimes, fans can expect plenty more from Taylor Sheridan’s money-making stable of bingeable dramas.
The most prominent new material involves spiritual sequel series The Madison. Starring Michelle Pfeiffer, it follows the story of wealthy matriarch Stacy Clyburn, who moves her family from NYC to Montana “in the wake of her husband and brother-in-law’s tragic deaths in a plane crash.”
Suits alum Patrick J. Adams, Matthew Fox, and Beau Garrett are set to join Pfeiffer. Cameras officially began rolling back in August 2024 in Montana, New York, and Texas with the expectation of a premiere sometime in late 2025.
Then there’s the Dutton Ranch spin-off with fan favourites Beth Dutton (Kelly Reilly) and Rip Wheeler (Cole Hauser) being developed as we speak – something we’ve noted will functionally exist as a sixth season and premire around the same time as The Madison.

“It’ll likely feature other cast members from the mothership series alongside Reilly and Hauser, I hear,” explained Nellie Andreeva of Deadline.
“Led by Yellowstone characters played by the same actors in the same present-day time frame, the new offshoot shares the most DNA with the mothership of any shows in the Yellowstone universe to date, which explains why it will be the first spinoff to carry Yellowstone in the title, sources said.”

Additionally, there’s the following:
- 6666
A present-day story about the legendary Four Sixes Ranch in Texas – which Taylor Sheridan owns in real life, because of course he does – backdoor piloted by the season 4 story arc of Jimmy Hurdstrom (Jefferson White), and built upon by the interstate arc heavily featured throughout season 5. - 1923
The ongoing prequel starring Harrison Ford, Helen Mirren, and Brandon Sklenar currently on its second season that follows the concluded 1883; centred upon a generation of the Dutton family during the titular year – a time of great hardships ranging from Prohibition, drought, and the early days of the Great Depression, which impacted Montana long before the Wall Street Crash of 1929. - 1944
Another prequel detailing the Dutton family’s troubled origins, picking up where 1923 eventually leaves off. Fun fact: prior to Kevin Costner’s exit, there were also discussions about a prequel set in the 80s with young John Dutton III.
