Prince William becomes a billionaire, overtaking King Charles

Prince William is officially a billionaire, with a net worth of $1.6 billion derived from the Duchy of Cornwall, which he inherited when Charles became king in 2022, the Sovereign Grant’s newly-published yearly accounts show. The accounts say William received a private income of $28.5 million in 2025-2026 and has paid more than $26 million in taxes since becoming the Prince of Wales four years ago.

King Charles III remains below billionaire status, with an estimated personal fortune of $846 million on the latest Sunday Times Rich List. The Duchy of Cornwall is a private estate set up in 1337 by King Edward III to provide funds for the heir to the throne. It covers roughly 205 square miles across the United Kingdom, spans more than 20 counties and supports William, Kate Middleton and their three children for official, charitable and private activities.
