Saddle up, Yellowstone fans — the next chapter of the Dutton saga is riding in faster than expected. CBS has officially greenlit Y: Marshals, a brand-new spin-off centered on Kayce Dutton, with Luke Grimes reprising his role. The series has received a 13-episode order and will begin filming this summer, targeting a mid-season 2026 premiere in a coveted Sunday night slot. Originally teased back in March, the project was made official as part of CBS’s upcoming 2025–2026 broadcast schedule reveal, marking the first time a Yellowstone series will debut directly on network TV rather than streaming on Paramount+.
When Yellowstone concluded its five-season run earlier this year, Kayce — the youngest Dutton sibling and former Navy SEAL — was one of the few family members left with a physical piece of the ranch. In Y: Marshals, the character takes a new path, trading the Yellowstone cattle brand for a federal badge.
According to the show’s official logline, Y: Marshals will follow Kayce as he joins an elite unit of U.S. Marshals tasked with keeping the peace in Montana. “With the Yellowstone Ranch behind him, Dutton joins an elite unit of U.S. Marshals, 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 defense in the region’s war on violence.” Translation? A whole lot of shootouts, moral dilemmas, and, yes, more cowboy hats and stoicism.
The series will be written and showrun by Spencer Hudnut, known for his work on SEAL Team, which makes him a perfect fit to steer Kayce’s evolution from ranch hand to lawman. Hudnut will executive produce alongside Yellowstone creator Taylor Sheridan, as well as David C. Glasser, Ron Burkle, David Hutkin, Bob Yari, Art Linson, and Grimes himself.
Why Is ‘Y: Marshals’ on CBS?
CBS Entertainment president Amy Reisenbach explained the network’s decision to bring the Yellowstone universe in-house. “All of our shows right now are both streaming and linear,” she said during the schedule reveal. “It certainly did occur to us that the show will do really well on streaming, because all the Taylor shows have. But Yellowstone and Tulsa King also did really well for us when we aired them on the network.”
That dual-platform success — particularly as audiences continue to blend streaming with appointment TV — makes CBS a logical home for a franchise that still draws huge numbers. And with Sheridan juggling multiple projects, Reisenbach added, “We’ll take what we can get.”
