500 Richest People Gained Record $2.2 Trillion in 2025, Fueling Calls for Wealth Tax

Led by Big Tech billionaires including Jeff Bezos, Larry Ellison, and Elon Musk, the world's 500 richest people added a record $2.2 trillion to their collective wealth in 2025, Bloomberg reported as the year ended on Wednesday.

"Obscene greed! While billions of people live in poverty," human rights campaigner Peter Tatchell responded on X—a social media platform now controlled by Musk, the richest person on Earth. "It's why we need a global wealth tax."

Musk—who could become the world's first trillionaire thanks to his new controversial pay package as CEO of Tesla—is one of just eight ultrawealthy individuals who got around a quarter of all the gains recorded by the Bloomberg Billionaires Index.

The others are Amazon founder Bezos and Oracle chairman Ellison, as well as Michael Dell, Google co-founders Sergey Brin and Larry Page, Jensen Huang of Nvidia, and Meta's Mark Zuckerberg. The previous year, Bloomberg noted, "the same eight billionaires made up 43% of the total gains."

According to Bloomberg, the gains that brought the combined net worth of all 500 people to $11.9 trillion "were turbocharged" by the 2024 election victory of President Donald Trump. The Republican and his relatives were among the "biggest winners" of 2025, gaining at least $282 million, for a net worth of $6.8 billion.

The "winners" also include Musk, who gained $190.3 billion for a net worth of $622.7 billion; Ellison, who gained $57.7 billion for a net worth of $249.8 billion; and Australian mining magnate Gina Rinehart, who gained $12.6 billion for a net worth of $37.7 billion.

After Trump's electoral win, several Big Tech billionaires buddied up to him, with Bezos, Musk, Zuckerberg, Apple CEO Tim Cook, and Google CEO Sundar Pichai all attending his inauguration. Musk then spent several months spearheading the administration's attack on federal workforce as the de facto leader of the Department of Government Efficiency (DOGE).

Sharing the Guardian's coverage of the findings on the social media network Bluesky, British climate scientist Bill McGuire warned that "if the monstrous political-economic system that is tearing our planet, the climate, and its people apart isn't brought to its knees—then humanity will be."

The Guardian pointed to Oxfam International's November statement that $2.2 trillion "would have been more than enough to lift 3.8 billion people out of poverty," which the humanitarian group highlighted ahead of the Group of 20 Summit hosted by South Africa, whose government used its G20 presidency to push for solutions to global inequality.

"Inequality is a deliberate policy choice. Despite record wealth at the top, public wealth is stagnating, even declining, and debt distress is growing," Oxfam executive director Amitabh Behar said at the time. "Inequality rips away life opportunities and rights from the majority of citizens, sparking poverty, hunger, resentment, distrust, and instability."

A June 2024 report from French economist and EU Tax Observatory director Gabriel Zucman—prepared for the G20's Brazilian presidency—estimated that a global 2% minimum tax on the wealth of 3,000 billionaires could generate about $250 billion.

As seven Nobel laureates, including Joseph Stiglitz, noted in a July op-ed published by the French newspaper Le Monde, "By extending this minimum rate to individuals with wealth over $100 million, these sums would increase significantly."
