Donald Trump’s business empire was supposed to be in peril like never before on Monday. Instead, it turned into the single-greatest day on record for the former president’s wealth. 

Facing a deadline to post a bond of more than $500 million in a New York fraud lawsuit, a state appeals court tossed him a lifeline, slashing the amount he’d have to post to $175 million — an amount he says he’ll cover. Around the same time, his social media company Trump Media & Technology Group wrapped up a 29-month-long merger process, meaning shares worth billions of dollars on paper are now officially Trump’s.

All told, his net worth increased by more than $4 billion. That means for the first time ever, Trump joined the ranks of the world’s wealthiest 500 people on the Bloomberg Billionaires Index, with a fortune of $6.5 billion.

We have a great company and are incredibly honored,” Eric Trump, executive vice president of the Trump Organization, said in a statement. 

Trump, 77, has been rich all his life. But his fortune, which previously peaked at $3.1 billion, has largely consisted of real estate properties, the value of which he and his company were found to have inflated by billions of dollars a year for more than a decade to get better terms on loans.
