[The World's Wealthiest Individuals Increased Their Wealth by a Record $2.2 Trillion This Year] Jin10 Data, December 31 – According to foreign media reports, a billionaire index from an institution shows that the collective wealth of the world's 500 richest individuals increased by a record $2.2 trillion this year. The booming markets, ranging from stocks to cryptocurrencies to precious metals, have driven the value of their assets to soar, bringing their total net worth to $11.9 trillion. Among them, tech giants led the growth, with the frenzy over artificial intelligence continuing to boost large-cap stocks in the U.S. Of all the wealth growth recorded by the institutional index, about a quarter came from eight 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 compared to last year, when these eight billionaires accounted for 43% of the total gains.
