The Gilded Age season 4 premieres in the United States on Sunday, 1 November 2026, at 9 p.m. ET/PT on HBO, with streaming on HBO Max. HBO has announced an eight-episode season, and its November programme guide says new episodes arrive weekly on Sundays. Morgan Spector is included in the returning ensemble.
The opening is less than a week away. HBO’s 13 October trailer announcement and 22 October November guide establish the date, episode count and US outlets. For viewers returning to the series, the story begins with the consequences of Bertha Russell’s success: HBO’s synopsis says she has changed high society but paid a heavy price within her family.

Premiere confirmed for November 1. Remaining dates calculated from HBO’s eight-episode, weekly-Sunday plan and cross-checked with Deadline. Schedule subject to change.
Eight Sundays, two US viewing routes
The announced weekly plan produces eight Sundays: 1, 8, 15, 22 and 29 November, then 6, 13 and 20 December. The table below follows that calendar, which also matches Deadline’s episode guide. The dates after the premiere are derived from HBO’s weekly schedule; a later change to that schedule would also change the expected finale date.
The 9 p.m. ET/PT wording is HBO’s television billing. The official announcements also name HBO Max, but do not separately specify a streaming unlock time for every US time zone. A viewer using a television provider can look up the HBO listing for 1 November; a streaming viewer can find The Gilded Age in the HBO Max app or website. Those are two access routes to the same season, with their own account and subscription conditions.
The family cost behind Bertha’s rise
Spector’s return sits within a broad cast that HBO lists alongside Carrie Coon, Christine Baranski, Cynthia Nixon, Louisa Jacobson and Denée Benton. The ensemble matters because the new story is not confined to one household: the official synopsis also follows Agnes as she tries to regain her place, Marian as she pursues a new path, and Peggy as she faces the question of acceptance by her future in-laws.
These are the conflicts HBO has chosen to preview, rather than an account of how the season ends. Bertha’s public gains and family costs give returning viewers a thread to pick up before the premiere. The other storylines extend that question of status and belonging across the cast. No unreleased episode outcome is needed to explain why the next chapter matters.
Plan the season around the official listings
For planning, use the official trailer announcement for the premiere and cast, and the November guide for the Sunday release pattern. Neither document establishes a free-viewing offer or a subscription price, and this article’s outlet list applies to the United States. It does not establish a UK broadcaster or UK release date. Readers arranging access should use the service’s own listing and the terms of their existing account.
The useful commitment now is an eight-week Sunday viewing plan beginning on 1 November, with 20 December as the expected final Sunday under that plan. The narrative question is what Bertha’s rise has cost the people around her. The premiere will begin to answer it; subsequent official episode listings will provide the firmer reference if the release calendar changes.
