PANews December 31 News, according to foreign media reports, the billionaire index of institutions shows that the collective wealth of the world’s top 500 richest people has increased by a record $2.2 trillion this year. All markets, from stocks to cryptocurrencies to precious metals, are booming, causing their asset values to soar. This wealth growth has brought their total net worth to $11.9 trillion. Among them, technology giants led the way, with the frenzy over artificial intelligence continuing to boost large-cap US stocks. Of all the wealth growth recorded by the Institutional Wealth Index, about a quarter comes from 8 individuals, including Oracle (ORCL.N) Chairman Larry Ellison, Tesla (TSLA.O) CEO Elon Musk, Alphabet (GOOG.O) co-founder Larry Page, and Amazon (AMZN.O) founder Jeff Bezos. However, it is worth noting that this contribution is smaller than last year, when these 8 billionaires contributed 43% of the total gains.
