The video more than doubled the best streaming result, which belonged to the third season of Euphoria, by reaching 277 million views in the first 48 hours
The teaser for HBO’s new Harry Potter series became the most watched in the network’s history by reaching 277 million views in the first 48 hours after launch on March 25, 2026.
With its performance, the teaser more than doubled HBO’s previous record, which belonged to the third season of Euphoria, with around 100 million views in the same 48-hour period.
The preview features the first glimpses of the new television adaptation of British author JK Rowling’s work, including Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley.
This total counts total organic views across multiple platforms – such as YouTube, Instagram, TikTok, X (formerly Twitter) and Facebook – within this initial period.
The number does not match a single video: The official YouTube counter, which records around 8 million views, represents just a fraction of the traffic. The record released by HBO considers the cross-platform sum, a common industry practice for measuring digital reach.
The series has premiere scheduled for Christmas 2026 and must adapt the first book in the wizard’s saga, Harry Potter and the Philosopher’s Stone, with the proposal to develop a season for each volume of the franchise.
Produced by HBO in partnership with Warner Bros. Television, the series is written and executive produced by Francesca Gardiner, with episode direction by Mark Mylod. Executive producers also include JK Rowling and David Heyman, responsible for the original films.
