Die 500 reichsten Menschen der Welt verdienten am Mittwoch mehr als eine Viertelmilliarde, als die volatilen Märkte auf den fragilen Waffenstillstand im Iran-Krieg reagierten

Wall Street traders saw a huge surge yesterday, and the world’s wealthiest billionaires had their best day in nearly a year, after President Donald Trump took back his threat that “a whole civilization will die tonight” on Tuesday, quelling traders’ fears.

The world’s 500 richest people made $265 billion yesterday, according to the Bloomberg Billionaires Index. With the Dow Jones Industrial Average jumping 2.85% and the S&P 500 soaring by 2.51%, it was the second-largest single-day profit since the index was created in 2012.

Meta CEO Mark Zuckerberg made the most gains and added $12.8 billion to his personal net worth as Meta shares—of which Zuckerberg owns about 13%—rose 6.5%. Luxury goods billionaire Bernard Arnault had the second-highest gains with $9.89 billion.

The largest gain for the world’s 500 wealthiest people was just a year ago tomorrow, on April 10. Last year on this day, Trump paused his planned “Liberation Day” tariffs, and the subsequent 24 hours of trading added a record $304 billion to the top 500 wealthiest’s net worths. In comparison, this Wednesday saw 61 people on the index grow their wealth by more than $1 billion.
