'The Traitors' Season 4 Promises Diabolical Deception & Treacherous Twists

No matter how you may feel about the dramatic first days of 2026, Peacock is ready to turn it all up to eleven with the arrival of a brand new season of its blockbuster reality show, The Traitors. Season 4 will see an all-new cast of reality stars, sports celebrities, and various famous-adjacent types descend on host Alan Cumming's mysterious castle in the Scottish Highlands, where they'll be asked to lie, scheme, and betray one another with abandon in the name of nabbing both viral screentime and a quarter of a million dollars.

The latest batch of contestants is perhaps the U.S. edition's most diverse yet. As usual, there is an assortment of former stars from reality stalwarts like Survivor, Big Brother, The Bachelor, and The Real Housewives franchise taking part. But this time around, they'll be joined by everything from actors and former Olympians to Taylor Swift's future mother-in-law.

The Season 4 cast includes:

• Candiace Dillard Bassett (The Real Housewives of Potomac)
• Caroline Stanbury (The Real Housewives of Dubai)
• Colton Underwood (The Bachelorette Season 14 & The Bachelor Season 23)
• Donna Kelce (Jason & Travis Kelce's Mother, a.k.a. Mama Kelce)
• Dorinda Medley (The Real Housewives of New York City)
• Eric Nam (KPop Singer-Songwriter)
• Ian Terry (Big Brother Seasons 14 & 22)
• Johnny Weir (Former Olympic Figure Skater-turned-Commentator)
• Kristen Kish (Top Chef Host)
• Lisa Rinna (The Real Housewives of Beverly Hills)
• Mark Ballas (Dancing with the Stars Professional)
• Maura Higgins (Love Island USA: Aftersun)
• Michael Rapaport (Actor, Only Murders in the Building)
• Monét X Change (RuPaul's Drag Race Season 10's Miss Congeniality)
• Natalie Anderson (Survivor: San Juan del Sur)
• Porsha Williams (The Real Housewives of Atlanta)
• Rob Rausch (Love Island USA Season 5)
• Rob Funches (Actor, Miracle Workers)
• Stephen Colletti (Actor, One Tree Hill)
• Tara Lipinski (Former Olympic Figure Skater-turned-Commentator)
• Tiffany Mitchell (Big Brother Season 23)
• Yamil "Yam Yam" Arocho (Survivor Season 44)

Last year's competition was full of drama, boasting unexpected blindsides, over-the-top gameplay, and roundtables that were the definition of must-see TV. (Particularly since the only people who seemed any good at sussing out the identity of the villainous Traitors were the actual Traitors themselves.) Season 4 seems primed to continue in that vein, as contestants promise to lie and cheat with abandon, amid scenes featuring fountains spouting blood, creepy clowns, unseen hands weilding chainsaws, and open graves.

But, as per usual, it's Cumming's wardrobe that's really the star of the show, and which, if the trailer is anything to go by, will be even more elaborate and over the top than seasons past. (That all-orange get-up is...certainly something. But I would buy a licensed version of that tank top with MURRRDER written in silver glitter right now.)

The Traitors Season 4 will premiere on Peacock with three episodes on Thursday, January 8, 2026, at 8 p.m. ET, followed by two episodes on January 15, and then one a week through the rest of the season. The Traitors U.K. Season 4 is also currently airing across the pond; all episodes are expected to arrive on Peacock after it concludes.
