HBO's Harry Potter Series Surpasses Game of Thrones in Budget — Over $200 Million

The budget estimate emerged following the publication of financial data from the British company Plum Jam Productions. It did not confirm that the 2026 revenues were specifically tied to *Harry Potter*, though a source familiar with the project called the show one of the most expensive in HBO's history.

Preliminary estimates suggest the costs are comparable to the budgets of the final seasons of *Game of Thrones* and *The Last of Us* — around $15 million per episode. The price was driven up not only by inflation but also by the large number of sets planned for use in future seasons.
