House of the Dragon Season 3 Premieres With the Battle of the Gullet

The opening episode shifts the series into full civil war with a cinematic sea‑and‑dragon clash that raises the stakes for characters and the franchise.

Overview

  • The third season premieres Sunday, June 21, 2026 at 9 p.m. ET on HBO and streams on HBO Max with new episodes released weekly through August 9.
  • Season 3 begins with the long‑teased Battle of the Gullet, a large naval fight featuring multiple dragons that showrunner Ryan Condal framed as one of the series’ most ambitious sequences.
  • The eight‑episode season pushes the succession narrative into open warfare between Team Black and Team Green and expands battlefield scale with added practical stunts and VFX.
  • Actor Steve Toussaint says his character Corlys Velaryon faces near‑death moments and a grief‑driven rampage that places him in risky, consequential situations this season.
  • The season builds on Season 2’s recruitment of ‘dragonseeds’ that increased Team Black’s dragon riders and arrives while HBO and Condal confirm a fourth and final season is in active development.
