Big Brother 28 now has its CBS premiere date: Thursday, July 9, 2026. The summer reality staple is returning with a 90-minute launch episode, a quick follow-up for Big Brother: Unlocked, and a season that CBS is positioning around a landmark 1,000th episode.
The key details are simple: CBS lists the Season 28 premiere for July 9 at 8/7c, while multiple TV schedule reports say the launch will run 90 minutes. Big Brother: Unlocked is set to return the following night, Friday, July 10, with another 90-minute episode planned for Sunday, July 12.



When does Big Brother 28 premiere?
Big Brother 28 premieres Thursday, July 9, 2026, at 8/7c on CBS. CBS is promoting the new season on its official Big Brother show page, while outlets including TVLine, Parade and TheWrap have reported the 90-minute premiere plan.
That gives fans a clear countdown after weeks of preseason speculation. The season arrives in the heart of the summer TV window, which is exactly where Big Brother usually performs best: live feeds, social conversation, nomination drama and eviction-night reactions all rolling together while the house is active.
What is the first-week schedule?
The reported opening schedule gives CBS three consecutive early touchpoints for fans:
- Thursday, July 9: 90-minute Season 28 premiere.
- Friday, July 10: Big Brother: Unlocked returns.
- Sunday, July 12: another 90-minute episode.
That is a busy launch, and it suggests CBS wants the season to feel bigger from the start. The return of Unlocked is especially notable because it gives the show a built-in place for extra context, audience reaction and house footage outside the regular edited episodes.
Why is the 1,000th episode important?
The 1,000th episode gives CBS an easy promotional hook for Season 28. Reality franchises rarely reach that kind of broadcast milestone, and Big Brother is unusual because so much of its appeal depends on viewers following events in near real time.
That milestone does not automatically confirm a twist, an all-star house or returning players. For now, CBS has confirmed the date and schedule shape, but the cast and theme still remain the biggest missing pieces.
When will the Big Brother 28 cast be revealed?
CBS has not announced the Season 28 houseguests yet. Based on recent Big Brother preseason patterns, the cast reveal is most likely to land close to premiere week rather than more than a month out. That means fans should be watching early July closely.
Until CBS confirms the names, any alleged cast list should be treated as rumour. The real reveal will matter because Season 28 is being framed as a major year for the franchise, and the houseguest mix will decide whether the season lives up to that billing.
Big Brother 28 quick facts
