Westeros is bigger than ever in 2026. What started with a single HBO drama has turned into a sprawling universe of prequels, sequels, an animated series, a stage play, and even a feature film. If you have been wondering exactly how many new Game of Thrones spin-offs are in the works right now, here is the complete, up-to-date rundown.
House of the Dragon Season 3 Premieres Today
The biggest Game of Thrones news of the moment is happening right now. House of the Dragon Season 3 premieres on HBO and HBO Max on June 21, 2026, at 9 p.m. ET, with the UK getting it on June 22. The eight-episode season covers events from George R.R. Martin’s book Fire & Blood and picks up directly where the brutal Season 2 finale left off, with the Dance of the Dragons civil war between Team Black and Team Green about to explode into full-scale war.
According to reporting from Deadline, the premiere episode opens with the Battle of the Gullet, which showrunner Ryan Condal has called one of the most ambitious episodes of television ever produced. The season runs weekly through a finale on August 9, 2026. Season 4 has already been confirmed and is expected in 2028, and showrunner Ryan Condal has revealed it will be the final season of the series.
A Knight of the Seven Kingdoms: The Spin-Off That Surprised Everyone
Before House of the Dragon returned, A Knight of the Seven Kingdoms quietly became one of the biggest surprises of the year. The series premiered on HBO and HBO Max on January 18, 2026, and is based on George R.R. Martin’s Tales of Dunk and Egg novellas, starting with The Hedge Knight.
Set roughly a century before the events of Game of Thrones, the show follows Ser Duncan “Dunk” the Tall, a lowborn hedge knight played by Peter Claffey, and his young squire Egg, secretly the future King Aegon V Targaryen, played by Dexter Sol Ansell. Unlike the political brutality of the original series, this spin-off leans into a warmer, more adventurous buddy tone.
The numbers back up the buzz. The show holds a 94% critics’ score on Rotten Tomatoes, was the single most-visited title on IMDb in February 2026, and was reportedly averaging close to 14 million viewers per episode in the United States by the end of its six-episode first season. HBO has already renewed the series for a second season, based on the novella The Sworn Sword, which is expected to arrive in 2027.
A Game of Thrones Movie Is Officially Happening
For the first time, the franchise is heading to the big screen. At CinemaCon 2026, Warner Bros. confirmed that a Game of Thrones film, currently going by the working title Aegon’s Conquest, is officially moving forward, with original showrunner-era writer Beau Willimon attached to script it. The project was placed in the studio’s “2027 and beyond” release window, so a theatrical premiere is still a few years out.
Based on Martin’s source material, Aegon’s Conquest would dramatize the founding of the Targaryen dynasty, when Aegon the Conqueror and his sister-wives flew their dragons across the Narrow Sea and unified the Seven Kingdoms for the first time, roughly 300 years before the events of the original Game of Thrones series.
Game of Thrones: The Mad King Hits the Stage
Not every new project is heading to a screen. The Royal Shakespeare Company has announced Game of Thrones: The Mad King, a stage play premiering at the Royal Shakespeare Theatre in Stratford-upon-Avon, running from July 20 through September 5, 2026. Adapted by Duncan Macmillan and directed by Dominic Cooke, the play dramatizes the final years of King Aerys II Targaryen’s reign and the Tourney at Harrenhal, the fateful event where Rhaegar Targaryen and Lyanna Stark first crossed paths, setting Robert’s Rebellion into motion.
The production will feature younger versions of characters familiar to Game of Thrones fans, including Ned Stark, Jaime Lannister, and Oberyn Martell. Given the demand, a future transfer to London’s West End or even Broadway would not be a surprise if the limited run performs well.
What’s Coming After That: Nymeria, the Sea Snake, and an Arya Sequel
Looking further ahead, HBO has several more spin-offs in active development:
Ten Thousand Ships is a prequel focused on Princess Nymeria and the Rhoynar, with a pilot script written by playwright Eboni Booth. George R.R. Martin has spoken enthusiastically about the project on his blog, though he has joked about the scale of the budget required to depict thousands of ships and hundreds of dragons.
An animated series about Corlys Velaryon, also known as the Sea Snake, is also in the works, chronicling his legendary nine voyages. Martin has teased early concept art on his personal blog but has not revealed a release timeline.
An Arya Stark sequel series is now in development from writer-producer Quoc Dang Tran as part of his overall HBO deal. This project effectively replaces the long-rumored Jon Snow spin-off starring Kit Harington, which Harington has said is “on the backburner for the moment,” though some reporting suggests elements of that concept could still resurface down the line.
