AceShowbiz - Since its debut in 2023, CBS' crime thriller Tracker has dominated the network's ratings, captivating audiences with its intense missing persons investigations. The series quickly established itself as the most-watched show in the 2023-2024 season and maintained that position for two consecutive seasons. However, the landscape is shifting dramatically in 2026 with the arrival of Marshals, a new 13-part Western procedural created by Taylor Sheridan.

The new series, which serves as a spin-off within the expansive Yellowstone universe, follows the youngest Dutton sibling as he joins law enforcement. Led by Luke Grimes, Marshals has successfully infiltrated the procedural genre, challenging and ultimately surpassing Tracker in popularity. This marks a notable change in CBS’ programming hierarchy, as the network’s procedural centerpiece is now overtaken by a fresh Western narrative.

Recent data from Nielsen’s TV ratings tracker reveals that Marshals is performing exceptionally well, outpacing every other broadcast show this season. The series has attracted 26.4 million viewers across CBS and Paramount+ within the first 28 days of release. In comparison, Tracker now ranks second on CBS with 16.4 million viewers. Streaming figures further bolster Marshals’ prominence, with FlixPatrol reporting it as the leading series on Paramount+.

Despite its rapid rise, Marshals is still trailing Netflix’s colossal hit Stranger Things, which returned for its final season late last year and remains the most-watched show overall, with a viewership lead of approximately 4 million more than Marshals.

Distinct from other Yellowstone universe spin-offs, Marshals is the first series to adopt a procedural format. The showrunner role is held by Spencer Hudnut, who previously led the acclaimed military drama SEAL Team. While Taylor Sheridan continues to exert creative influence as an executive producer, he has yet to receive writing or directing credits on this series.

The series has already secured a renewal for a second season, which is scheduled to premiere this fall. Meanwhile, new episodes of Marshals are airing every Sunday on CBS, continuing to build momentum and captivate its growing audience.

In the context of CBS’ programming, this shift indicates a significant evolution, with Marshals redefining the network’s appeal through its blend of Western themes and procedural storytelling. The success of the series highlights the enduring popularity of Taylor Sheridan’s storytelling approach and the appetite for fresh narratives within familiar universes.

As Marshals continues to rise, it remains to be seen whether it will close the gap with Stranger Things and claim the title of the most-watched show overall. For now, it stands as CBS’ top new series and a major contender in the competitive television landscape of 2026.
