Billionaires are facing uncertain times as their wealth growth stagnates, with the number of individuals worth over a billion reaching 2,682, up from 1,757 a decade ago. The total assets of these billionaires have surged to $14 trillion, outperforming global stock markets, but challenges such as higher taxes, geopolitical tensions, and a lagging real estate sector loom ahead. As governments seek fiscal stability amid rising spending needs, many billionaires are relocating to countries like Switzerland, the UAE, and Singapore, while focusing on emerging sectors like generative AI and renewable energy.
