Overview
- Season 4 rolls out on HBO in the U.S. starting January 11 and on BBC One/BBC iPlayer in the U.K. from January 12, following a weekly release schedule.
- The new storyline centers on Tender, a newly public payments firm, debating its business with Siren, an OnlyFans-like site, against the backdrop of age‑verification laws highlighted by the U.K.’s Online Safety Act.
- Creators Mickey Down and Konrad Kay say the age‑verification focus grew more topical during production, with real‑world effects such as a reported 80% drop in Pornhub’s U.K. traffic after the 2025 rules took effect.
- Harper leads a short-selling push targeting Tender as the season adopts investigative and crime‑thriller textures, expanding beyond the trading floor and stretching to new locales including Ghana and northern England.
- Early notices are strongly positive, praising a sharper, darker season with an expanded cast — Max Minghella, Kiernan Shipka, Kal Penn and Charlie Heaton among them — and highlighting Sagar Radia’s more emotionally demanding turn as Rishi.
