HBO’s new Harry Potter series could cost about $25 million (£18.6 million) per episode, according to an estimate reported by entertainment website Deadline, potentially putting it among the most expensive television productions ever made.
The figure is an estimate, not a confirmed budget. Nieuws.nl reports that Deadline based it on the accounts of British production company Plum Jam Productions, which is responsible for the series. Plum Jam recorded revenue of £130.6 million in 2025, up from £18.4 million in 2024. It is unclear whether all of that income came from Harry Potter, and HBO has not commented on the figures.
The reported per-episode cost would place the series in the same broad bracket as expensive HBO productions such as Game of Thrones and The Last of Us. A person familiar with the production told Deadline that costs for the first season are relatively high because large sets are being built for use in later seasons.
The series is due to begin in December and will retell J.K. Rowling’s seven books, with one season for each. Dominic McLaughlin plays Harry Potter, Alastair Stout plays Ron Weasley and Arabella Stanton plays Hermione Granger.
