Is J.K. Rowling Still the Only Billionaire Author in 2025?

J.K. Rowling’s journey from a struggling single mother to the first-ever billionaire author is a remarkable story. Her success, largely thanks to the Harry Potter series, made her one of the most financially successful writers ever. With global book sales, movies, spin-offs, theme parks, and merchandise, she built an empire that set new standards for authors.
However, her success also raised a big question: could anyone else ever reach such financial heights? Over the years, authors have seen their fortunes soar, fueled by movie adaptations, streaming deals, and viral social media moments. But the billion-dollar mark remains elusive. So, as we reach 2025, nearly 20 years after Rowling’s breakthrough, is anyone else close?
Is J.K. Rowling Still the Only Billionaire Author in 2025?
As of 2025, J.K. Rowling remains the only author to have crossed into the billionaire club due to her literary work. While other writers like James Patterson, Stephen King, Nora Roberts, and Colleen Hoover have earned significant wealth, none have reached Rowling’s financial heights. In fact, by 2025, Rowling is no longer considered a billionaire, due to her charitable donations and taxes.
Rowling’s lasting financial success comes from turning Harry Potter into a global brand. Beyond the books, which have sold over 600 million copies, the Wizarding World includes theme parks, plays, a film franchise (Fantastic Beasts), and a new streaming series. These ongoing ventures continue to generate royalties and licensing fees, setting her apart from her peers.
James Patterson and Jim Davis, each worth around $800 million, are the closest to Rowling. Patterson is known for his “Alex Cross” series, while Davis created the “Garfield” comic strip. Yet, both are still far from the billion-dollar mark, leaving Rowling alone in that exclusive club.
