Mark Zuckerberg fell to fifth place on the Bloomberg Billionaires Index — the lowest in nearly two years — as investors spooked by Meta Platforms Inc.’s planned $30 billion debt sale sent the company’s shares spiraling amid a flurry of tech earnings shaking up the ranks of the world’s richest.

Meta’s stock fell 11% — the most since 2022 — after the company said it was going to issue the biggest investment-grade bond offering of the year to boost spending on artificial intelligence research, dropping Zuckerberg’s net worth to $235.2 billion, according to the wealth index.
