HBO Max, Paramount+, Peacock and Netflix are all adding fresh content to their line‑ups in the coming weeks, with three high‑profile series set to drop on June 21 and several new seasons already available.

The most anticipated release is HBO Max’s House of the Dragon Season 3, which is scheduled to premiere on Sunday, June 21, 2026. The eight‑episode season will continue the Targaryen civil war that began in the first two seasons, focusing on the rivalry between Rhaenyra Targaryen (Emma D’Arcy) and her half‑brother Aegon II (Tom Glynn‑Carney). The new season introduces James Norton as Ormund Hightower, a key supporter of Team Green.

Paramount+ will also release its second season of the espionage thriller The Agency on the same day. All ten episodes of Season 2 will be available for binge‑watching on June 21. The series, produced by George Clooney and Grant Heslov, follows CIA agent Brandon Colby (Michael Fassbender) who is now a double agent for MI6. The plot centers on his efforts to rescue his lover, Samia (Jodie Turner‑Smith), who is a political prisoner in Sudan.

Peacock’s British spy drama The Capture has already rolled out its third season. The six‑episode run follows Rachel Carey (Holliday Grainger) as she leads a Counter‑Terrorism Command unit that has launched a mass‑surveillance program called Operation Veritas. The season explores the manipulation of the surveillance system during a London mass shooting.

Netflix has added a new mystery series to its catalogue. I Will Find You Season 1, adapted from Harlan Coben’s novel, is available now. The eight‑episode series stars Sam Worthington as David Burroughs, a man in prison who claims he did not kill his 3‑year‑old son. The plot follows Burroughs as he attempts to locate his son’s alleged killer after a photograph of an 8‑year‑old boy surfaces.

The release of these series reflects a broader trend of streaming platforms investing heavily in original drama. House of the Dragon has already drawn over 10 million viewers on its first day of broadcast, making it the most‑watched HBO premiere in history. The show has earned multiple Emmy nominations and a Golden Globe for Best Television Series – Drama.

The Agency has been renewed for a second season following a positive reception to its first season, which aired in 2024. The series is noted for its complex character dynamics and the moral ambiguity of its spycraft.

The Capture continues to build on its commentary about the dangers of surveillance technology, a theme that has resonated with audiences amid growing concerns about privacy.

Netflix’s I Will Find You follows a proven formula for the studio’s Coben adaptations, which have previously included Fool Me Once and Missing You. The series adds to Netflix’s library of crime thrillers that attract viewers who prefer serialized storytelling.

All four releases are currently available on their respective platforms, with the exception of House of the Dragon and The Agency, which will debut on June 21. Viewers who prefer to binge can already stream The Capture and I Will Find You.

In summary, June 2026 will see the launch of two major new seasons on HBO Max and Paramount+, while Peacock and Netflix continue to offer fresh content for their audiences. The timing of these releases positions the platforms to capture viewers looking for high‑quality drama and espionage thrillers during the summer season.
