That’s the figure the artificial intelligence boom—prompted by OpenAI’s ChatGPT, and then filtering through to announcements from Google, Microsoft, Meta, Amazon, and more—is estimated to have added to the pockets of the global superrich.

Large language models like ChatGPT have been the buzzword on the stock market this year—new VC funds have been launched in an attempt to back the next disrupter, while existing Big Tech has seen a windfall after jumping on the bandwagon.

Microsoft cofounder Bill Gates was one of the first to see a direct boost to his philanthropic fortune courtesy of the phrase A.I.

The Bill & Melinda Gates Foundation founder saw his fortune spike by $2 billion following an A.I.-themed Microsoft earnings call in April, which sent the business’s share price skyrocketing.

In the days after the earnings report, Gates, who owns an estimated 103 million shares in the company, saw his wealth grow by approximately $40 million for each of the 50 times the phrase “artificial intelligence” was uttered on the call.

According to the Bloomberg Billionaires Index, Gates’ worth has risen by $24 billion so far this year.

Meta windfall

For Mark Zuckerberg—Meta’s largest individual shareholder—a combination of the “year of efficiency” and making A.I. the company’s priority has resulted in a near–$40 billion boost.

Meta’s shares have enjoyed a recovery this year—up 125% in 2023 so far—as Zuckerberg has moved away from his metaverse dream, returning to reality with swaths of job cuts.

Zuckerberg—who famously takes only $1 in salary annually—also began teasing the company’s adventures into A.I. this year, hinting at its deployment at the end of January before making a major announcement about a new A.I.-focused project group at the end of February.

Ahead of the January announcement, Zuckerberg’s wealth sat at $55.1 billion, and since the A.I. announcement in February his wealth has grown from $63 billion to $102 billion.

Rich get richer

Oracle CTO Larry Ellison has moved ahead of Bill Gates in the Billionaires Index, courtesy of the business‘s announcements about accelerating the deployment of A.I.

The company’s cofounder and former CEO owns a 35% stake in the $338 billion business—whose share price is up nearly 50% year to date.

Like Zuckerberg’s, Ellison’s boost in fortune came following a major announcement from Oracle about A.I.—on a March earnings call during which the company discussed its plans for the technology at length.

The call was on March 9—when Ellison’s fortune was worth around $99.7 billion—and within a week his net fortune began steadily rising. It now sits at $138 billion, according to the Bloomberg Billionaires Index.

Of course, the man at the helm of Wall Street A.I. darling Nvidia has also seen his wealth soar.

Jensen Huang, one of three cofounders of the chip, software, and systems creator and its current president and CEO, has seen the share price of the company swell by 198% so far this year.

The business—which specializes in artificial intelligence products and services—has steadily cemented itself at the heart of the A.I. revolution, and Huang reportedly owns 1.3 million shares of it.

As a result, Huang’s wealth has nearly tripled since January, from $13.8 billion to $38.3 billion according to the index—contributing to Markets Insider’s calculation that the rich list has gained $150 billion this year thanks to A.I.
