HBO confirmed on July 28, 2025, that there would be a Season 4 (only days before the finale for season 3), which generated excitement about what was expected next. HBO announced, "the series is one of television's most irresistible dramas," and commended Fellowes' insight into the art of marrying historical storytelling with contemporary relevance.

We don’t know for sure when The Gilded Age Season 4 will come out, but considering it took about a year and a half to make the third season of the show, we can make an educated guess. The earliest The Gilded Age Season 4 might hit HBO would be late 2026.

HBO has handed a Season 4 renewal to Julian Fellowes’ period drama The Gilded Age. The pickup comes ahead of the Season 3 finale on August 10, which will wrap some storylines while setting up more drama and intrigue.
