Prince William Becomes Billionaire, Surpassing King Charles' Wealth

Prince William has entered the billionaire club with an estimated net worth of £1.2 billion, overtaking his father King Charles III, whose wealth is placed at about £640 million. The figures come from the annual Sovereign Grant report for the 2025‑2026 fiscal year, which detailed that the Duchy of Cornwall generated roughly £21.6 million in private income for William, while the Duchy of Lancaster produced a £25.2 million surplus for Charles. Both royals disclosed their tax payments, with William reporting £7.76 million and Charles £12.9 million. The disclosure follows speculation about Prince Harry’s financial situation and his planned return to the UK, adding further public interest to the royal family’s finances.

The transparency of these disclosures highlights the financial distinction between the heir apparent’s Cornwall estates, which span more than 51,800 hectares across 19 counties, and the sovereign’s Lancaster holdings. The announcement underscores the shifting economic profile of the British monarchy as public scrutiny intensifies.
