Something significant is happening in late night television right now and the numbers are impossible to ignore. Jimmy Kimmel Live has posted its strongest single night rating of the entire post Colbert era, drawing over 2.3 million viewers in a performance that is sending a clear message to every network executive watching.
Kimmel is not just surviving the void left by Stephen Colbert. He is thriving in it.
The context here matters enormously. For most of his career, Kimmel spent his 11:35 slot trailing Colbert by a considerable margin. At one point during Colbert’s peak years, that gap was roughly 2.3 million viewers. Kimmel kept grinding, kept building, and slowly closed the distance. By the fourth quarter of 2025, the gap had narrowed to around 300,000 viewers and Kimmel had actually overtaken Colbert in the key 18 to 49 demographic for the first time ever.
Then Colbert left. And the dam broke entirely.
The week of June 1st alone told the full story. According to Nielsen Live Plus 3 data, Kimmel averaged 2.89 million total viewers across that week, up 19 percent. His post NBA Finals episodes were even more extraordinary. Wednesday’s broadcast after Game 1 of the Finals drew 3.98 million viewers, making it the second highest rated episode of the season. Friday’s post Game 2 episode pulled 3.38 million, ranking fifth for the season.
Year over year comparisons make the picture even clearer. Kimmel pulled 2.72 million viewers in the week of June 1st compared to just 1.64 million in the same week last year. That is a 66 percent surge. Jimmy Fallon’s Tonight Show, by comparison, grew a much more modest 11 percent over the same period.
What is happening here is not luck. Kimmel has spent years positioning himself as the sharpest, most consistent voice in the 11:35 slot. He has taken political risks that other hosts have avoided. He has built a loyal audience that shows up even on quiet news weeks. When the biggest slot in late night opened up, his audience was already there and Colbert’s former viewers needed somewhere to go.
Many of them went to Kimmel. And right now, they are staying.
