Tonight is the night Big Brother fans have been waiting for: the Season 27 finale will air live — so what time is Big Brother on tonight, exactly? Below, we break down all the timing details, how to tune in, what to expect, and who’s left in the game.
What Time Does Big Brother Come On Tonight / Big Brother Finale Time
The live two‑hour finale is slated to begin at 8:30 p.m. ET / PT, which corresponds to 7:30 p.m. CT.
Because tonight’s episode is a live special, it differs from the season’s usual scheduling.
In Central Time, that means Big Brother will air tonight at 7:30 p.m. CT.
To recap:
- Eastern / Pacific Time: 8:30 p.m.
- Central Time: 7:30 p.m.
So if you’re asking “what time is Big Brother on tonight” or “what time is the Big Brother finale,” these are your exact times for tonight’s live event.
What Time Is the Big Brother Finale / When Is Big Brother Finale
Tonight’s finale marks the conclusion of an 83‑day run for Big Brother Season 27, which began with filming on July 8, 2025, and premiered on July 10 on CBS.
This particular finale is a special live edition lasting two hours.
Multiple outlets confirm the finale’s timeslot: 8:30–10:30 p.m. ET.
If you’re in Central Time, that runs from 7:30–9:30 p.m. CT.
Thus, the big brother finale time tonight is confirmed: 8:30 p.m. ET / 7:30 p.m. CT, concluding at 10:30 p.m. ET / 9:30 p.m. CT.
Big Brother Tonight: Where to Watch & Streaming Options
The finale will air on CBS live across the U.S.
For cord‑cutters, streaming is available via Paramount+.
Earlier in the day, the 24/7 live feeds will go offline as production takes over for the finale.
So whether you tune in via your local CBS channel or via streaming, just be sure to dial in at 8:30 p.m. ET / 7:30 p.m. CT.
Final Contestants, Stakes & What to Watch
Tonight’s finale features the final three: Morgan Pope, Ashley Hollis, and Vince Panaro.
They are battling for a grand prize of $750,000.
Tonight’s format includes:
- Final Head of Household (HOH) competition (Part 3 live)
- Last eviction or reveal of the Final 2
- Jury vote and crowning of the winner
- Reveal of the twisting “BB Mastermind,” a season‑long mystery element
One rumor being floated is that former Big Brother winner Dr. Will Kirby could emerge as the Mastermind — though nothing has been confirmed.
Why Tonight’s Timing Differs from the Normal Schedule
During the regular season, Big Brother airs three nights a week: Sundays, Wednesdays, and Thursdays at 8:00 p.m. ET, with Wednesday episodes running 90 minutes.
But for Finale Week, CBS made adjustments:
- Sunday (finale): 8:30 p.m. ET start time, two hours long
- Wednesday (Sept. 24): moved to 10:00 p.m. ET and shortened from 90 to 60 minutes due to Survivor’s premiere
- Thursday (Sept. 25): 90-minute episode at 8:00 p.m. ET
Thus, tonight’s push to 8:30 p.m. aligns with CBS’s special scheduling for live events and the finale presentation.
How to Prepare & What to Watch For
Here’s how to make the most of the night:
- Be ready by 8:30 p.m. ET / 7:30 p.m. CT, because the show will start promptly.
- Confirm your streaming service is working (Paramount+) if you’re not on CBS.
- Expect the usual finale staples: emotional speeches, jury reveals, blindsides, and the winner announcement.
- Keep your eyes on the Mastermind reveal. That twist is a signature of this season.
Whether you asked “what time is Big Brother tonight,” “when is the Big Brother finale,” or “what time is the Big Brother finale,” you now have the exact times and what to expect. Tune in tonight — the crown will be claimed at 10:30 p.m. ET / 9:30 p.m. CT.
Enjoy the finale!
