The Big Brother 27 episode schedule is ready, and CBS will soon debut the BB27 cast members. It’s been a long hiatus since we saw Chelsie Baham win Big Brother 26, but the producers have selected a new group of houseguests to compete for the $750,000 prize this summer.
Big Brother 27 episodes will return to the familiar Sunday, Wednesday, and Thursday presentation, but there have been some changes designed to give fans even more coverage. The Wednesday night episodes are now 90 minutes long, following the trend that has worked well for Survivor and The Amazing Race.
CBS is also presenting a new Friday night installment that will feature Big Brother alums discussing the action from Big Brother 27. The Friday night episodes will air every other week on CBS. Big Brother legends will return to discuss the current season’s happenings.
Below is a breakdown of when fans should tune in to CBS for the Big Brother 27 episodes. It all gets started with the BB27 season premiere on Thursday, July 10.

More on the Big Brother Summer 2025 season
Show producers have hinted that we could see a version of the AI Arena return this summer. Having the AI Arena means we could see three nominees each week, much like how BB26 worked. A $750,000 prize is on the line again, and we are going to see many former houseguests through those Friday night episodes.
We will likely see the BB27 cast list a week before premiere night. Expect CBS to start pushing out additional commercials as the start date draws near. For now, mark those calendars, because July has many new Big Brother episodes.
