Prince William Joins the Billionaires Club and Surpasses King Charles in Wealth
Prince William, the heir to the British throne and Prince of Wales, has officially joined the ranks of billionaires. According to the latest financial estimates, his net worth now exceeds $1.6 billion, making him wealthier than his father, King Charles III.
The figures were released following the publication of the annual Sovereign Grant accounts and the latest Sunday Times Rich List. They indicate that Prince William’s fortune is now nearly twice that of the British monarch, whose wealth is estimated at approximately $846 million.
The bulk of Prince William’s fortune comes from the Duchy of Cornwall, one of the oldest and most valuable private estates of the British Crown. Ownership of the duchy was automatically transferred to him when King Charles III ascended the throne in 2022, making William the Prince of Wales and heir apparent.
Founded in 1337 by King Edward III, the Duchy of Cornwall was established to provide a permanent source of income for the heir to the throne. It includes an extensive portfolio of land, residential and commercial properties, farms, and investments spread across more than 20 counties in the United Kingdom, covering approximately 205 square miles.
The duchy serves as Prince William’s primary source of income, funding both his personal and official expenses, as well as those of his wife, Catherine, Princess of Wales, and their three children—Prince George, Princess Charlotte, and Prince Louis. It also supports their charitable work and official engagements.
The latest financial statements show that Prince William received approximately $28.5 million in private income during the 2025–2026 financial year, generated by the duchy’s investments, real estate holdings, and rental income.
The reports also state that he has voluntarily paid more than $26 million in taxes since assuming control of the duchy, despite not being legally required to do so under British law. The move has been presented as part of his commitment to financial transparency.
Meanwhile, King Charles III’s personal fortune is estimated at around $846 million, representing a decline of approximately $40 million compared with the previous year, leaving him outside the billionaire club.
Following the death of Queen Elizabeth II, King Charles inherited several private estates, including Balmoral Castle and the Sandringham Estate, in addition to the personal assets he had accumulated during his time as Prince of Wales.
However, the transfer of the Duchy of Cornwall to Prince William provided him with a significantly larger financial base, thanks to the estate’s substantial value and stable income, ultimately securing his place among the world’s billionaires.
Beyond managing the duchy as a source of revenue, Prince William is also seeking to modernize its operations. According to several British media reports, he is considering selling around 20% of the duchy’s assets over the next decade as part of a long-term development strategy.
