Its first official teaser had already arrived on October 9, 2025; HBO Max later published a final trailer on December 4. The announced premiere date was January 19 in Norway and Japan, reflecting local schedules rather than a conflicting US date.
When did A Knight of the Seven Kingdoms premiere?
The release date depended on the market. HBO’s US announcement set the premiere for January 18, 2026, at 10 p.m. ET/PT. Warner Bros. Discovery Norway listed January 19, while Warner Bros. Japan said the series would begin streaming in Japan on January 19 at noon local time through HBO Max on U-NEXT.
| Market and service | Announced premiere | Schedule detail |
|---|---|---|
| United States — HBO and HBO Max | January 18, 2026, at 10 p.m. ET/PT | Six episodes, according to Warner Bros. Discovery US. |
| Norway — HBO Max | January 19, 2026 | Warner Bros. Discovery Norway announced six half-hour episodes, with a new episode each Monday. |
| Japan — HBO Max on U-NEXT | January 19, 2026, at noon Japan time | Warner Bros. Japan described the launch as simultaneous with the US release. |
The calendar-day difference is consistent with a Sunday-night US launch falling on Monday in some territories. These are launch announcements, not confirmation of present-day availability: streaming catalogs and regional rights can change. Check the local service for current access.
Has the first trailer arrived?
Yes. HBO Max’s official listing dates the first teaser trailer to October 9, 2025, the day Warner Bros. Discovery Norway announced it at a New York Comic Con panel. HBO Max’s official listing for the final trailer is dated December 4, 2025. Warner Bros. Japan’s December 8 announcement also discussed the main trailer.

What is the prequel about?
Set about a century before Game of Thrones, the series follows Ser Duncan the Tall, known as Dunk, and his young squire Egg as they travel through Westeros. Peter Claffey plays Dunk and Dexter Sol Ansell plays Egg. George R. R. Martin is a co-creator and executive producer; Ira Parker is co-creator, showrunner, and executive producer.
The series adapts Martin’s Dunk and Egg stories. Readers who want the source material can find the publisher’s HBO tie-in paperback edition, a 368-page collection of the three prequel novellas. Reading the book is not necessary to follow the show.
