George R.R. Martin Confirms New ‘Game of Thrones’ Spinoffs and Sequels Still in Development

The world of Game of Thrones is far from finished, and George R.R. Martin has now confirmed that several new projects—both prequels and sequels—are still actively in development. For fans who have been eagerly waiting to see what direction HBO will take after the success of House of the Dragon, this update is one of the biggest signs yet that Westeros will continue to grow beyond the stories we already know.

According to Martin, there are currently about five or six spinoffs being developed. This doesn’t mean all will reach the screen, but it does show just how ambitious HBO’s long-term strategy is. Martin explained that he is collaborating with “some great people” on these new shows, which are at various stages of development. Some have detailed outlines, some are being scripted, and others are still just ideas being explored. His involvement confirms their legitimacy, even if their timelines remain uncertain.

What Martin made very clear is that most of these projects are prequels. This isn’t surprising considering how rich the history of Westeros is. Viewers have already responded strongly to House of the Dragon, which explores the Targaryen civil war nearly 200 years before the events of the original series. HBO seems committed to digging deeper into that ancient past.

Among the known prequels previously mentioned are Aegon the Conqueror, which would follow the first Targaryen king as he unites Westeros with his dragons, and Ten Thousand Ships, a legendary tale centered on Princess Nymeria and the journey that led to the founding of House Martell in Dorne. These stories are massive in scope, mythic in tone, and perfectly suited for world-building on a scale similar to the early seasons of Game of Thrones.

However, the biggest surprise from Martin’s update is the confirmation that some sequels are also in development. For years, fans have speculated about the possibility of continuing the stories of characters who survived the original series. While Martin didn’t reveal which sequels are being considered, this admission alone opens the door to a wide range of possibilities. It could mean exploring Arya’s adventures “west of Westeros,” Jon Snow’s life beyond the Wall, or even the political future of King Bran’s reign.

The potential Jon Snow sequel, in particular, has been talked about since 2022, when reports suggested Kit Harington was attached to the idea. While HBO never officially confirmed it, Martin’s latest comments suggest that sequel concepts are still alive, even if not guaranteed. The idea of revisiting existing characters is a huge draw for fans who felt the original finale left several story paths unresolved.

Martin also reminded audiences that “in development” is not the same as “greenlit.” HBO previously spent millions on a pilot for Bloodmoon, a prequel set thousands of years before Game of Thrones, which was eventually cancelled. The network is cautious, and each new project has to match the cultural impact and production standard expected from the franchise. Still, the sheer number of ideas being explored shows a powerful commitment to the future of the franchise.

For fans, the biggest takeaway is simple: Westeros isn’t going anywhere. The universe is expanding again, and with a mix of prequels and sequels on the table, the next decade could bring some of the most exciting stories the series has ever told. Even though not all of these projects will make it to air, the possibilities alone are enough to spark fresh anticipation.

With Martin deeply involved and HBO continuing to invest in large-scale fantasy, the world of Game of Thrones is entering a new era—one filled with history, mystery, and the promise of returning to the characters and kingdoms we’ve never truly let go of.
