After months of rumors and speculation, CBS has confirmed that Y: Marshals will premiere on Sunday, March 1, 2026, at 8 p.m. ET, giving fans a long-awaited return to the Dutton universe.
A Surprise Instagram Reveal From Luke Grimes
Grimes, who has remained relatively quiet on social media in recent months, broke his silence in a cryptic yet thrilling Instagram post on November 17. Sharing a promotional image of himself wearing Kayce’s iconic cowboy hat, he simply captioned it:
“March 1.”
The teaser sent fans into a frenzy. With no extra details, the two-word post quickly filled with excited comments from followers eager to see where Kayce’s journey will go next.
“This is gonna be so good!!! Cannot wait to delve further into Kayce’s story,” one fan gushed.
“OMG I CAN’T WAIT 🤩,” another wrote.
First Look Trailer Drops — and Raises Questions
If that wasn’t enough, CBS followed up the news with a first-look trailer, released on November 24. The brief but atmospheric clip teased the return of Kayce — this time stepping into the world of federal law enforcement.
While full plot details are still under wraps, the trailer confirmed the series will air on both CBS and stream on Paramount+, keeping it accessible for Yellowstone’s massive fanbase.
The trailer caption read:
“Luke Grimes stars as Kayce Dutton in Y: Marshals, a CBS Original. Premieres March 1, 2026, on CBS and streaming on Paramount+.”
What Is Y: Marshals About?
Though CBS and Paramount have yet to reveal a full synopsis, early buzz suggests Y: Marshals will follow Kayce Dutton’s transition from Yellowstone rancher to U.S. Marshal, blending the franchise’s rugged Western tone with a federal crime drama twist.
Given Kayce’s complex past as a Navy SEAL and Livestock Agent, the setup promises rich emotional stakes, high-stakes action, and deep moral conflicts — all set against the American West’s harsh backdrop.
Yellowstone Universe Keeps Growing
Y: Marshals is just one of several projects expanding the Yellowstone universe. With the original series wrapping up and additional spin-offs like 1944 and 6666 in the works, Taylor Sheridan’s Dutton saga is evolving into one of television’s most ambitious storytelling landscapes.
Grimes stepping into a lead role cements Kayce Dutton as a central figure in the franchise’s future — and gives longtime fans a familiar character to anchor the next chapter.
