CBS and TNT Sports Deliver Most-Watched Opening Weekend of March Madness Ever

The 2026 NCAA Men’s Basketball Tournament tipped off with a bang, setting multiple viewership records right out of the gate and signaling strong fan interest in what promises to be a highly competitive March Madness.

By the numbers

Thursday’s opening-round games, broadcast across CBS, TNT, TBS, and truTV, averaged 9.8 million viewers, marking the best opening day on record for this multi-network setup. This figure represents a solid 6% increase from the previous year’s Thursday slate, building on the momentum from a record-setting regular season where networks like Fox and CBS reported their strongest college basketball viewership in years. The surge reflects growing national appeal for men’s college hoops, fueled by compelling storylines, powerhouse programs, and consistent high-quality play.
The primetime window on Thursday proved especially dominant, averaging 12.5 million viewers. This was driven by standout matchups like Michigan vs. Howard and VCU vs. North Carolina, delivering the most-watched first-round primetime block in tournament history. These games not only drew massive audiences but also showcased intense, well-played basketball that kept viewers locked in. The combination of competitive contests and star power from top-seeded teams helped push numbers higher than in recent years.
Overall, the tournament’s early viewership is off to its best start ever, with an average of 9.3 million viewers across the initial games, up 5% from the comparable point in 2025. This builds directly on the First Four’s success earlier in the week, where truTV saw its highest-ever average of 7.5 million viewers for the play-in games, topped by Miami (OH) vs. SMU at 2.8 million. Things started out well from the start with the Selection Show, which drew 6.4 million, the highest in over a decade.

Why are ratings up with fewer upsets?

While past tournaments often thrived on chaotic upsets and Cinderella runs that captivated casual fans, this year’s first round has featured fewer major shocks. Instead, the lack of massive upsets has highlighted the depth and talent at the top of the field. Quality teams are advancing as expected, allowing viewers to witness elite matchups and skilled play from the outset. Fans are getting to see the “creme rising to the top,” with chalk results producing tight, high-level games rather than blowouts or bracket-busters early on.
This shift hasn’t hurt ratings; in fact, it may be enhancing them by delivering consistent appointment viewing with recognizable programs and competitive stakes. The combination of fewer upsets and strong basketball has created a different kind of excitement: one built on excellence rather than chaos. Top seeds and proven contenders are showcasing why they earned their spots, leading to games that feel like must-watch events. This approach aligns with broader trends in sports consumption, where audiences increasingly tune in for high-caliber competition amid a crowded media landscape.
As the tournament progresses into the second weekend and beyond, these record numbers set a promising tone. With the regular season laying a foundation of elevated interest and the opening days exceeding expectations, 2026 March Madness is positioned for continued growth. Whether chalk continues to hold or late-round surprises emerge, the early metrics confirm that fans are engaged and the product is resonating strongly on TV.
