The Season 3 premiere of “House of the Dragon” racked up 21.5 million global viewers in its first three days of availability, according to Warner Bros Discovery.

A combination of Nielsen’s measurement of viewers on HBO‘s cable channel and Warner Bros. Discovery’s own data regarding streams on HBO Max, that total represents a slight decrease of 8% from the three-day viewership total achieved by the Season 2 premiere in 2024. The second season managed to cross 23.4 million viewers in three days, though it should be noted that Season 3 is competing for viewership with the FIFA World Cup.
