Just eight billionaires accounted for a quarter of the gains, led by Elon Musk, Jeff Bezos, Larry Ellison and Larry Page

The richest 500 individuals in the world added a record $2.2tn to their wealth in 2025, according to the Bloomberg Billionaires Index, with just eight billionaires accounting for a quarter of the gains.

The gains increased their collective net worth to $11.9tn, bolstered by billionaire Donald Trump’s 2024 election victory and booming markets in cryptocurrencies, equities and metals.

Around a quarter of the gains were attributed to eight billionaires, including Elon Musk, Jeff Bezos, Oracle chair Larry Ellison and Alphabet Inc co-founder Larry Page, though 2024 saw more concentrated net worth gains with the same eight billionaires making up 43% of total net worth gains for the wealthiest 500 individuals in the world.
