The Gilded Age Season 4: 7 Shocking Plot Predictions Based On The 1884 Historical Timeline

Contents

The Gilded Age Season 4 is officially happening, and the news couldn't be more triumphant for fans of Julian Fellowes' lavish American drama. Just weeks before the Season 3 finale, HBO announced the series' renewal on July 28, 2025, confirming that the high-stakes battle between New Money and Old Money will continue. With the show's timeline moving into the pivotal year of 1884, the next season promises to be the most dramatic yet, introducing a major financial crisis that could threaten the foundations of the Russell empire and completely reshape the social landscape of Fifth Avenue.

As of today, December 21, 2025, while an official release date remains unconfirmed, industry speculation and production rumors—including a planned return to filming in Troy, New York, in February 2026—point toward a likely premiere in late 2026 or early 2027. The next chapter will pick up directly after the explosive events of the Season 3 finale, where Bertha Russell’s social triumph and George Russell’s near-fatal confrontation set the stage for a new era of ambition, risk, and revenge.

The Gilded Age Season 4: Cast, Release Date, and Production Status

The core of the show’s success lies in its stellar ensemble cast, and fans can expect almost all major players to return for the fourth season, ensuring continuity in the intricate web of New York society.

  • Official Renewal Date: July 28, 2025
  • Expected Release Date: Late 2026 or 2027 (based on previous production schedules)
  • Filming Status: Rumored to begin on February 23, 2026, with a return to locations in Troy, New York.

Confirmed and Highly Likely Returning Cast Members

The central drama of the Russell and van Rhijn/Brook households will continue with the return of its powerhouse leads and supporting cast. The following stars are all expected to reprise their roles:

  • Carrie Coon as Bertha Russell
  • Morgan Spector as George Russell
  • Cynthia Nixon as Ada van Rhijn
  • Christine Baranski as Agnes van Rhijn
  • Louisa Jacobson as Marian Brook
  • Denée Benton as Peggy Scott
  • Harry Richardson as Larry Russell
  • Blake Ritson as Oscar van Rhijn
  • Taissa Farmiga as Gladys Russell
  • Simon Jones as Bannister (The Russell Butler)
  • Ben Ahlers as Jack Treacher (The Footman)
  • Kelley Curran as Turner (The Maid, possibly returning for a new scheme)

The return of the full ensemble is crucial, as Season 4 will need all hands on deck to navigate the turbulent waters of the 1884 political and financial climate, which will impact every character, from the New York elite to the downstairs staff.

7 Shocking Plot Predictions for the 1884 Timeline

Julian Fellowes’ writing is meticulously tied to real-world history, with each season advancing the story by approximately one year. Season 4 will be set in 1884, a year marked by significant financial turmoil and political upheaval. These historical markers allow for strong predictions about the major storylines and character arcs.

1. George Russell Faces the Panic of 1884

The most significant historical event of 1884 was the Panic of 1884, a sharp bank panic that hit New York City, triggering a recession. This event is a tailor-made plot device for George Russell, the industrialist. After surviving the assassination attempt in the Season 3 finale, George will be forced to fight a new, invisible enemy: a collapsing financial market. This storyline will explore the fragility of the "New Money" fortunes and could see George having to make ruthless decisions to save his mills and his family's wealth, potentially putting him at odds with his wife, Bertha, whose focus remains on social climbing.

2. Bertha Russell’s War with Mrs. Astor Escalates to a New Level

Bertha achieved a massive social victory by successfully hosting the Duke of Buckingham and securing a place for her daughter, Gladys Russell, in high society. However, the social war is never truly over. With Bertha’s status solidified, her next target will likely be to challenge the ultimate gatekeeper, Caroline Schermerhorn Astor (Mrs. Astor), on an even grander scale, perhaps by hosting a major charity event or attempting to gain control of a key social institution. The 1884 political climate, including the Presidential Election of 1884, may provide a new arena for the two women to clash over influence and patronage.

3. Marian Brook’s Romantic Crossroads and New Professional Path

Marian Brook, the innocent niece caught between the Old World of Agnes van Rhijn and the New World of the Russells, is due for a major life decision. Her romantic life, which has seen her navigate relationships with multiple suitors, must finally move forward. More importantly, her professional aspirations, possibly involving her work with the Red Cross or other charitable causes, will put her on a collision course with the rigid expectations of her aunt, Agnes. The season may see Marian striking out on her own, possibly moving out of the van Rhijn mansion to pursue a career or a more independent life.

4. Peggy Scott’s Journalism and the Rise of Labor Issues

Peggy Scott's storyline is crucial for exploring the social and racial realities beneath the Gilded veneer. As a talented writer and journalist, Peggy's work for the New York Globe will inevitably lead her to cover the growing labor movement and the struggles of the immigrant working class, especially in the wake of the Panic of 1884. This could create a direct conflict with George Russell, whose mills and factories are the very places where these labor disputes are brewing, forcing Peggy to choose between her professional integrity and her friendship with the Russells.

5. The Fate of Oscar van Rhijn’s Fortune

Oscar van Rhijn’s disastrous financial speculation in Season 3 left the van Rhijn family’s fortune severely depleted. Season 4 must deal with the fallout. The Panic of 1884 will make it nearly impossible for Oscar to recover his losses quickly. This desperation could lead him to take even greater risks, or, more dramatically, force him to finally go through with a marriage of convenience to a wealthy heiress, potentially someone from the new money set, much to the horror of his mother, Agnes van Rhijn.

6. The Resolution of the Downstairs Romance

The Season 3 finale left a major cliffhanger for the downstairs staff, particularly the budding romance between footman Jack Treacher and maid Bridget. Their relationship, which has been a slow burn, is expected to finally reach a conclusion. Given the show's focus on social mobility, Jack’s pursuit of his invention (the patent clock) could finally pay off, offering him and Bridget a way out of service and into a life of their own, mirroring the upward trajectory of the New Money class.

7. The Introduction of New Historical Figures and Socialites

To keep the social circle fresh, Fellowes is known for introducing historical figures. As the show moves deeper into the 1880s, we can expect to see new, powerful socialites or political figures. The 1884 setting provides an opportunity to introduce figures related to the burgeoning arts scene or the political machines of the time, such as Tammany Hall, which would add a new layer of political intrigue to the Russell-van Rhijn rivalry. The continued expansion of New York society, including the increasing importance of places like Newport, Rhode Island, will also feature heavily in the new season.
