Where can I watch Traitors USA season 4?

Streaming on Peacock

• Peacock is the exclusive US home for The Traitors US season 4, with the season premiering on January 8, 2026 (Peacock). All 10 episodes are available on demand for subscribers.
• The episodes aired weekly on Thursdays at 9/8c (Peacock).

BBC iPlayer availability

• UK viewers can watch the full season on BBC iPlayer, with the first four episodes dropping back-to-back on June 25, 2026 (Radio Times).

RTÉ Player in Ireland

• Irish audiences can stream the season via RTÉ Player, which carries the series following the UK broadcast schedule.

The implication for viewers outside the US: Peacock’s exclusive window means the show arrives on UK and Irish platforms only after the US season finishes, creating a time gap that super-fans may want to navigate carefully.

Will Traitors US season 4 be on BBC?

BBC iPlayer streaming

• Yes — BBC iPlayer is the confirmed UK home for The Traitors US season 4. The BBC announced the series would land on the platform starting June 25, 2026 (Radio Times).

BBC One broadcast

• The series also broadcasts on BBC Three, with episodes airing in blocks rather than weekly instalments. The initial drop includes four episodes back-to-back (Radio Times).

The pattern for UK viewers: unlike Netflix or Prime Video, BBC iPlayer’s catch-up model means the entire season becomes available at once, encouraging binge-watching rather than weekly appointment viewing.

How to watch Traitors US in Ireland?

RTÉ Player access

• RTÉ Player is the official Irish platform for The Traitors US. Irish viewers can stream the season free of charge after the UK broadcast window opens.

VPN streaming considerations

• Some Irish viewers may consider using a VPN to access Peacock or BBC iPlayer directly, though users should check terms of service for each platform. RTÉ Player remains the straightforward legal route (CinemaBlend).

What this means for Irish audiences: RTÉ Player offers a free, local solution, but fans wanting the earliest possible access might need patience or a Peacock subscription with a US-based payment method.

Who won the traitors season 4 US?

Winner announcement

• Rob Rausch won The Traitors US season 4, taking home US$220,800 (The Hollywood Reporter; TV Insider).
• He won as a Traitor, not as a Faithful, solidifying his strategic gameplay (USA Today).

Rob Rausch details

• Rausch is known from Love Island USA, and his win marked a milestone for contestants originally from dating shows transitioning into game-driven reality competitions.
• Maura Higgins, also from Love Island, finished as runner-up in the season (Wikipedia).

Why this matters for viewers: Rausch’s win as a Traitor reinforces a season-long narrative about deception and alliance management — a key selling point for fans of the series who watch for the psychological gameplay.

What is the Traitors US season 4 cast?

Full contestant list

• The all-star cast includes Candiace Dillard Bassett (The Real Housewives of Potomac), Caroline Stanbury (Ladies of London), Colton Underwood (The Bachelor), Dorinda Medley (The Real Housewives of New York City), and Eric (from The Challenge) (USA Today).
• Lisa Rinna (The Real Housewives of Beverly Hills) also joined the roster, alongside Rob Rausch and Maura Higgins (USA Today).

Celebrity backgrounds

• The cast draws heavily from Bravo reality shows, Netflix’s Love Is Blind alumni, and MTV’s The Challenge franchise — a deliberate casting strategy to create pre-existing rivalries and alliances (Radio Times).

The pattern across the cast list is intentional: producers stacked the season with contestants who had existing relationships from other shows, amplifying the paranoia and trust dynamics central to The Traitors format.

Timeline

• August 14, 2024: Season 4 announced
• January 8, 2026: Season 4 premieres on Peacock (US)
• June 25, 2026: Season 4 lands on BBC iPlayer (UK)
