‘The Late Show With Stephen Colbert’ Finale Draws 6.74 Million Viewers, A Franchise Record For A Weeknight

CBS closed the book on The Late Show With Stephen Colbert – and on the entire Late Show franchise – with a ratings surge that underlined just how big a presence the host remained in late night to the very end.

Finale Ratings At A Glance

The series finale on Thursday, May 21, 2026 delivered 6.74 million live+same‑day viewers, according to preliminary Nielsen data, making it the most‑watched regular weeknight episode in the history of Colbert’s Late Show run, CBS said. 

That tally narrowly beats the audience for Colbert’s debut on September 8, 2015, which launched to around 6.55 million viewers, and is more than double the show’s recent‑season average of roughly 2.7 million viewers. 

The only Late Show instalment to draw a larger audience under Colbert remains the post–Super Bowl 50 special in 2016, which aired in primetime and pulled more than 20 million viewers – a very different scheduling advantage than the 11:35 p.m. series finale enjoyed. 

A Huge Spike Above A Shrinking Baseline

In a late‑night landscape where linear audiences have steadily eroded, the finale’s performance stands out:

• The show’s 2026 Q1 average sat at about 2.7 million viewers per episode. 
• Colbert’s second‑to‑last week already saw a big farewell bump, averaging 3.3 million viewers and reclaiming the title of most‑watched late‑night show from Fox News’ Gutfeld! for the first time in 2026. 
• The finale itself effectively tripled the typical nightly audience, underscoring how many lapsed or online‑only viewers returned to CBS for the last hurrah.

Nielsen’s national numbers for Live+Same Day viewing don’t capture delayed DVR/streaming consumption, but preliminary data already make the finale the most‑watched weeknight episode Colbert has ever hosted and the biggest late‑night broadcast of the current season. 

How It Compares To Other Late‑Night Farewells

In raw audience terms, Colbert’s last Late Show doesn’t touch the mega‑finales of previous eras – but those aired in a very different TV universe.

Major Late‑Night Finales: Viewer Comparison

Measured against its own era—where even leading late‑night shows average well under 3 million live viewers—Colbert’s finale is a clear outlier on the high side. 

CBS: Retiring A Ratings Leader For Financial Reasons

The finale’s numbers are all the more striking because CBS chose to cancel The Late Show and retire the entire franchise despite Colbert remaining No.1 or neck‑and‑neck in total viewers. 

• In Q2 2025, The Late Show averaged about 2.42 million viewers and led traditional late‑night competitors in total audience. 
• The network nonetheless announced in July 2025 that the Colbert‑hosted show would end in May 2026, citing “purely financial” considerations in a late‑night market eroded by streaming and social‑media clips. 
• Trade reporting later suggested the series was losing more than $40 million a year, in part due to Colbert’s salary and rising production costs, even as it remained the timeslot’s ratings leader. 

The finale’s 6.74‑million audience therefore doubles as a last, slightly awkward ratings victory for CBS: proof that a still‑popular show can be sacrificed when the economics no longer work.

Inside The Finale: A Warm Goodbye, Not A Ratings Stunt

While the ratings were huge, the episode itself was deliberately low‑key by late‑night farewell standards.

• Colbert opened with an emotional monologue, admitting he was “lucky enough to be here for the last 11 years” and praising his staff as “The Joy Machine.” 
• The broadcast ran roughly 80–90 minutes, featuring musical and comedy segments rather than a wall‑to‑wall clip show. 
• Paul McCartney was the final main guest, performing “Hello, Goodbye” with Colbert to close the night. 
• A sci‑fi‑tinged sketch saw past late‑night hosts and celebrities appear around a “wormhole” that eventually swallowed the Late Show set – a meta gag about the end of the entire CBS franchise. 

Earlier in his final week, Colbert welcomed David Letterman and former President Barack Obama, and reunited with fellow Strike Force Five hosts Jimmy Kimmel, Jimmy Fallon, Seth Meyers and John Oliver, episodes that themselves delivered some of CBS’s biggest late‑night numbers in years (4.1M viewers for the host reunion, 3.7M for Letterman’s return). 

What The Ratings Say About Late Night’s Future

The finale underscores a paradox:

• Audience appetite for big, cultural late‑night moments clearly still exists—viewers will show up when something feels special or historic.
• Yet night‑to‑night economics of producing a high‑cost, network late‑night show have grown fragile as audiences fragment across streaming and social platforms.

Colbert leaves with an average of ~2.5–2.7 million nightly viewers in his final seasons and a finale that nearly hit 7 million—strong by any modern standard—yet CBS still concluded that retiring The Late Show and returning the 11:35 p.m. slot to affiliates made more financial sense. 

For fans, the 6.74‑million figure is simply a numerical confirmation of what the finale’s mood already conveyed: for one last night, a very large chunk of America wanted to say goodbye.
