The Big Brother 28 cast reveal is set for Tuesday, July 7, 2026, giving fans their first official look at the new houseguests before the CBS premiere. This year, CBS is changing the usual rollout by turning the announcement into a live digital event called Big Brother: Broveal, rather than simply publishing names and photos online.

The livestream begins at 12 p.m. ET / 9 a.m. PT on the official Big Brother YouTube channel. Host Julie Chen Moonves will introduce the Season 28 houseguests and take viewers inside the new Big Brother: Time Trip house before the game officially begins.

Official season details, episode access and streaming information are available through the CBS Big Brother page.

What Time Is the Big Brother 28 Cast Reveal?

The Big Brother 28 cast reveal takes place at 12 p.m. ET on Tuesday, July 7. For viewers on the West Coast, that is 9 a.m. PT.

The cast had not been revealed before this event, which makes the livestream the key moment for fans waiting to see who will enter the house. The reveal is expected to introduce the new houseguests before the Season 28 premiere airs two days later.

That timing gives fans a short window to study first impressions, compare personalities and start predicting early alliances. In Big Brother, even the first few hours of fan reaction can shape which contestants become early favorites or targets in online discussion.

Where to Watch Big Brother: Broveal

The first Big Brother: Broveal will stream on the official Big Brother YouTube channel. The free livestream format makes the cast reveal easier to access for viewers who may not yet have cable or Paramount+.

Julie Chen Moonves will lead the event and preview the new house design. CBS has branded Season 28 as Big Brother: Time Trip, a theme built around rooms, relics and competitions inspired by different moments in time.

This digital-first rollout is a notable change for the franchise. Instead of making the cast announcement a quiet pre-premiere update, CBS is using it as a standalone fan event designed to build conversation before opening night.

When Does Big Brother 28 Premiere?

Big Brother 28 premieres Thursday, July 9, 2026, at 8 p.m. ET on CBS. The first episode will run for 90 minutes, giving the show more time to introduce the houseguests, explain the Time Trip setting and begin the opening phase of gameplay.

The season will also stream on Paramount+. As usual, the format follows houseguests living together while cut off from the outside world, with cameras and microphones recording their strategy, relationships, conflicts and evictions.

Reality competition shows often build momentum through weekly twists, surprise eliminations and live audience reactions. A recent Love Island USA elimination recap shows how quickly fan discussion can shape expectations before the next episode airs.

What Is the Time Trip Theme?

The Season 28 theme is Time Trip. CBS has said the house will include spaces and competitions connected to different eras, with early twists expected to affect the game from the start.

The theme could matter beyond decoration. Big Brother twists can influence safety, nominations, voting power or competition advantages. If the Time Trip concept is used carefully, it could add pressure without taking attention away from the players’ social strategy.

The main challenge is balance. Fans usually respond best when twists create drama but do not replace the decisions made by the houseguests. The strongest seasons are often built around trust, timing, betrayal and shifting alliances.

Big Brother: Unlocked and Live Feeds

The companion show Big Brother: Unlocked returns on July 10 at 8 p.m. ET. Former winners Taylor Hale and Derrick Levasseur are returning as hosts, with Jerry O’Connell joining as a celebrity panelist.

Live feeds begin at 9 p.m. ET on July 10 on Paramount+ and Pluto TV. CBS is also adding limited live-feed availability on YouTube after episodes during the summer.

That matters because Big Brother is not only an edited television show. Much of the fan conversation comes from live feeds, where viewers track alliances, strategy talks, arguments and moments that may not appear fully in broadcast episodes.

Why the Cast Reveal Matters

The cast reveal is one of the most important moments before any Big Brother season. Viewers immediately look for possible strategists, social players, competition threats and early targets.

Season 28 adds extra attention because the rollout combines a live cast reveal, a themed house tour, a 90-minute premiere, a returning companion show and expanded live-feed access. Big Brother has completed 27 regular U.S. seasons, along with spin-offs including Celebrity Big Brother, Big Brother: Over the Top and Big Brother Reindeer Games.

For now, the key date is July 7. That is when fans will finally see who is entering the Time Trip house and begin judging which players may have the patience, social game and timing needed to last the summer.
