The richest kid in the world as of 2025 is Princess Charlotte of Wales, with an estimated net worth of approximately £3.9 billion (about $5 billion). She surpasses other royal siblings and celebrity children in wealth, largely due to her royal inheritance prospects and the influence of the "Kate effect"—her mother Kate Middleton's significant impact on fashion trends, which boosts Charlotte's financial prominence. Charlotte is expected to inherit substantial assets from the royal family, including future inheritances from her father Prince William, her grandfather King Charles III, and the late Queen Elizabeth II
. Among celebrity children, Rza Athelston Mayers, son of Rihanna and A$AP Rocky, is notably wealthy with a net worth near £943.5 million ($1.2 billion), making him the richest A-list celebrity kid
. Other young billionaires under 30 include Johannes von Baumbach, heir to Germany's Boehringer Ingelheim pharmaceutical company, who is the world's youngest billionaire at age 19, and self-made billionaires like Ed Craven ($2.8 billion) and Alexandr Wang, but their net worths are below that of Princess Charlotte
. In summary, Princess Charlotte holds the top spot as the richest child globally due to her royal status and inheritance, with a net worth far exceeding other wealthy children in 2025.
