The Traitors' season 4 finale drew 9.4 million viewers, setting a record for non-celebrity episodes.

The fourth season of BBC’s The Traitors concluded with a record-breaking finale, drawing 9.4 million viewers on average and peaking at 9.6 million, making it the most-watched non-celebrity episode in the series' history. Hosted by Claudia Winkleman, the finale saw Rachel and Stephen win as the first duo to claim victory, outlasting the remaining contestants in a dramatic final round. The episode surpassed the previous year’s finale by over two million viewers, though it did not exceed the 11 million who watched the 2025 Celebrity edition. The strong performance supports the show’s renewal for season 5, with casting already underway.
