A new Oxfam report reveals that billionaire wealth surged three times faster in 2025 than the previous five years, driven by AI. The US tech giants, including Nvidia and Microsoft, poured over $400 billion into AI infrastructure, translating to a 27.5% stock gain. The report warns that rising wealth concentration could exacerbate political inequality, with billionaires now 4,000 times more likely to hold office than ordinary citizens.
