In a world where late-night television is a battleground for viewers' attention, Stephen Colbert's final month as host of 'The Late Show' was a triumph. The May 2026 ratings reveal a fascinating story, one that goes beyond simple numbers and highlights the power of a well-loved host and a loyal audience.
The Colbert Effect
Colbert's departure created a unique surge in viewership, with his final month drawing an impressive 4.20 million nightly viewers, a 49% increase from the previous month. This surge wasn't just a one-off for the finale; it was a three-week farewell celebration. What makes this particularly fascinating is the context: a TV landscape where cord-cutting and changing habits have significantly reduced late-night audiences. Colbert's ability to draw such numbers is a testament to his appeal and the show's enduring popularity.
A Swan Song
The finale itself was a ratings juggernaut, with 9.77 million viewers tuning in, making it the show's highest-rated weeknight episode ever. This episode not only topped the post-Super Bowl broadcast in terms of viewers but also in share, with an impressive 33.32% of TV viewers at that time choosing to watch Colbert's last dance. In the key demo of adults 18-49, the finale ranked as the show's seventh most-watched episode, averaging 1.58 million viewers.
The Impact on Competitors
Interestingly, Colbert's gains didn't come at the expense of his competitors. Both Jimmy Kimmel and Jimmy Fallon saw growth in their audiences, with Kimmel's show placing second in total viewers and Fallon's show showing a healthy 17% increase. This suggests that Colbert's departure created a broader interest in late-night TV, benefiting the entire genre.
Post-Colbert CBS
May also marked the first post-Colbert numbers for CBS, with Byron Allen's 'Comics Unleashed' taking over the 11:35 p.m. slot. While the show averaged a respectable 941,000 total viewers in its first half-hour, it's a far cry from Colbert's numbers. The second nightly episode at 12:05 a.m. saw a drop in viewers, averaging 612,000. Allen's other show, 'Funny You Should Ask,' which took over the 12:35 a.m. slot, also saw lower numbers, averaging 475,000 total viewers.
Year-Over-Year Growth
Looking at the bigger picture, the total audience across tracked programs grew significantly in May 2026 compared to May 2025. This growth is notable, especially considering the challenges of the TV landscape. Colbert's show led the way with a massive 79% jump in total viewers and a staggering 144% increase in the demo. Other shows like 'Jimmy Kimmel Live!' and 'The Tonight Show Starring Jimmy Fallon' also saw impressive gains.
Conclusion
Colbert's final month as host was a ratings triumph, but it also highlights the broader trends and challenges facing late-night TV. While Colbert's departure created a unique surge, the overall growth in viewership is a positive sign for the genre. It will be interesting to see if the new hosts can maintain this momentum and if late-night TV can continue to adapt and thrive in a changing media landscape. Personally, I think Colbert has set a high bar, and it will be fascinating to see who steps up to the challenge.
