World's richest 500 gained record $2.2 trillion in 2025, led by eight billionaires

The 500 wealthiest people globally gained a record $2.2 trillion in 2025, a sum Oxfam noted could lift billions out of poverty, driven by market booms.

Limerick brothers and Stripe co-founders Patrick and John Collison have a net worth of €8bn each according to Bloomberg.

The richest 500 individuals in the world added a record $2.2tn (€1.9tn) 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 (€10.1tn), bolstered by billionaire Donald Trump’s 2024 election victory and booming markets in cryptocurrencies, equities and metals.
