Overview
- Oxfam reports billionaire fortunes rose 16% in 2025 to a combined $18.3 trillion, with wealth up about 81% since 2020.
- The group says the 12 richest individuals hold more wealth than the poorest half of humanity and estimates last year's billionaire gains roughly match the wealth held by that half.
- Oxfam argues extreme wealth distorts governance, estimating the ultra‑rich are 4,000 times likelier to hold political office and that policies they support pass far more often than those they oppose.
- In France, the NGO says 53 billionaires are richer than more than 32 million people and that French billionaire wealth has doubled since 2017, as it urges a Zucman tax on fortunes above €100 million, higher dividend and inheritance levies, a financial transactions tax, and a revamped ISF with a climate surtax.
- Debate over the report is intense, with critics citing falling global poverty rates, the limits of market‑based wealth valuations, and the legal and political obstacles to coordinating robust international wealth taxes.
