Luke Grimes is proving that the Yellowstone universe still has plenty of gas in the tank. The new spinoff series Marshals premiered March 1, 2026, on CBS and Paramount+ to a staggering 20.6 million multiplatform viewers in its first week. According to Nielsen data shared by CBS, the debut marks the most-watched network original series premiere without a football lead-in since Young Sheldon launched in 2017.

The massive success led CBS to hand out an early Season 2 renewal on March 12, 2026, just two episodes into the first season. "Marshals delivered a breakout performance, capturing a massive audience across platforms and quickly establishing itself as one of TV’s most powerful new series," CBS Entertainment President Amy Reisenbach said in an official statement. The show shifts the focus from ranching to law enforcement, following Kayce Dutton as he leaves the Yellowstone Ranch to join an elite unit of U.S. Marshals in Montana.

Created by showrunner Spencer Hudnut, the procedural series brings back familiar faces including Brecken Merrill as Tate Dutton, Gil Birmingham as Thomas Rainwater, and Mo Brings Plenty as Mo. New additions to the cast include Logan Marshall-Green as Pete Calvin and Arielle Kebbel as Belle Skinner. The 13-episode first season is currently airing on Sundays at 8/7c, marking a new chapter for the franchise following the conclusion of the original flagship series.
