Bezos, already the world’s richest person, added $13.2 billion to his fortune in about 15 minutes. At the current price, his net worth would be about $129.5 billion, according to the Bloomberg Billionaires Index.

Bezos, 56, owns about 12% of Amazon’s outstanding stock, making up the bulk of his fortune. His ownership of closely held Blue Origin accounts for about $6.2 billion. The late surge Thursday added more than $90 billion to Amazon’s market value, pushing it above $1 trillion.

His ex-wife, MacKenzie Bezos, 49, also has reason to celebrate, as she owns about 4% of the Seattle-based retailer. She started the day as the world’s 24th-richest person, with a $37.1 billion fortune.

Bezos wasn’t the only tech titan with dramatic changes to their net worth this week following company earnings. Elon Musk’s fortune swelled by $2.3 billion in an hour Wednesday after shares of Tesla Inc. rose in extended trading on better-than-expected results. Mark Zuckerberg’s fortune tumbled $4 billion as Facebook shares slid on its slowest-ever quarterly sales growth.
