The Gilded Age will kick off its fourth season on Sunday, November 1, 2026, at 9 p.m. ET/PT, available on both HBO and HBO Max. This sumptuous drama transports viewers to 1880s New York City, a vibrant era of rapid change and intense social stratification. At its heart is the clash between the entrenched "old money" elite and the ambitious "new money" industrialists vying for acceptance and power.

The narrative centers on Marian Brook, an orphaned young woman from the South who arrives in New York to live with her traditional aunts, Agnes van Rhijn and Ada Brook. Accompanying her is the enigmatic and talented Peggy Scott, an African-American writer navigating her own path in a society rife with racial and class barriers. Their lives quickly intertwine with their fabulously wealthy neighbors, George and Bertha Russell. Bertha, a formidable railroad tycoon's wife, is relentless in her pursuit of social dominance, often challenging the established order personified by figures like Agnes van Rhijn.

Season 3 left Bertha's relentless social climbing with significant personal costs, particularly straining her marriage to George. As Season 4 unfolds, viewers can expect these consequences to reverberate through the Russell household. The upcoming season's plot indicates that Agnes van Rhijn will seize an opportunity to reclaim her former societal standing, while Marian embarks on a new personal journey. Peggy, meanwhile, will face challenges in gaining acceptance from her prospective in-laws, underscoring the series' ongoing exploration of social boundaries and personal ambition. This new chapter promises that in this opulent era, careful consideration must be given to one's desires.

The acclaimed ensemble cast returns, featuring Carrie Coon as the ambitious Bertha Russell, Christine Baranski as the formidable Agnes van Rhijn, and Cynthia Nixon as the kind-hearted Ada Brook. Morgan Spector portrays the powerful George Russell, while Louisa Jacobson leads as Marian Brook, and Denée Benton plays the compelling Peggy Scott. Also reprising their roles are Taissa Farmiga, Harry Richardson, and Audra McDonald, ensuring a rich tapestry of interwoven storylines.

For those looking to catch up or revisit the drama, the first three seasons of "The Gilded Age" are currently available to stream on HBO Max.
