Artificial intelligence startups have minted dozens of new billionaires this year, adding to an AI boom that’s quickly becoming the largest wealth creation spree in recent history.

Blockbuster fundraising rounds this year for Anthropic, Safe Superintelligence, OpenAI, Anysphere and other startups have created vast new paper fortunes and propelled valuations to record levels. There are now 498 AI “unicorns,” or private AI companies with valuations of $1 billion or more, with a combined value of $2.7 trillion, according to CB Insights. Fully 100 of them were founded since 2023. There are more than 1,300 AI startups with valuations of over $100 million, the firm said.

Combined with the soaring stock prices of Nvidia, Meta, Microsoft and other publicly traded AI-related firms, along with the infrastructure companies that are building data centers and computing power and the huge payouts for AI engineers, AI is creating personal wealth on a scale that makes the past two tech waves look like warmups.

“Going back over 100 years of data, we have never seen wealth created at this size and speed,” said Andrew McAfee, principal researcher at MIT. “It’s unprecedented.”

A new crop of billionaires is rising with sky-rocketing valuations. In March, Bloomberg estimated that four of the largest private AI companies had created at least 15 billionaires with a combined net worth of $38 billion. More than a dozen unicorns have been crowned since then.

Mira Murati, who left Open AI last September, launched Thinking Machines Lab in February. By July, she raised $2 billion in the largest seed round in history, giving the company a $12 billion valuation, according to reports.

Anthropic AI is in talks to raise $5 billion at a valuation of $170 billion, nearly three times its valuation in March. CEO Dario Amodei and its six other founders are now likely multibillionaires, according to people familiar with the company.

Anysphere was valued at $9.9 billion in a June fundraise and just weeks later was reportedly offered a valuation of $18 billion to $20 billion, likely making its 25-year-old founder and CEO, Michael Truell, a billionaire.

Granted, most of the AI wealth creation is in private companies, making it difficult for equity holders and founders to cash out. Unlike the dot-com boom of the late 1990s, when a flood of companies went public, today’s AI startups can stay private for longer given the constant investment from venture capital funds, sovereign wealth funds, family offices and other tech investors.

At the same time, the rapid growth of secondary markets is allowing equity owners of private companies to sell their shares to other investors and provide liquidity. Structured secondary sales or tender offers are becoming widespread. Many founders can also borrow against their equity.

Open AI is holding talks for a secondary share sale to provide cash to employees. Its proposed valuation of $500 billion follows the company’s fundraise in March that provided a $300 billion valuation.

Dozens of private firms are being acquired or merging, also providing liquidity. After Meta invested $14.3 billion in Scale AI, founder Alexandr Wang joined Meta’s AI team. There have been 73 liquidity events — including mergers and acquisitions, IPOs, reverse mergers or corporate majority stakes — since 2023, according to CB Insights. Following the Meta deal, Scale AI’s co-founder, Lucy Guo, who left the company in 2018, bought a mansion in LA’s Hollywood Hills for around $30 million.

Still, the AI surge is largely centered in the Bay Area, reminiscent of the dot-com era. Last year, Silicon Valley companies raised more than $35 billion in venture funding, according to the Silicon Valley Institute for Regional Studies. San Francisco now has more billionaires than New York, with 82 compared with New York’s 66, according to New World Wealth and Henley & Partners. The Bay Area’s millionaire population has doubled over the past decade, compared with New York’s growth of 45%.

More homes sold above $20 million in San Francisco last year than in any other year in history, according to Sotheby’s International Realty. Rising rents, home prices and demand in the city, attributed in large part to AI, mark a sharp turnaround for a city facing a “doom loop” just a few years ago.

“It’s astonishing how geographically concentrated this AI wave is,” said McAfee, who is also co-director of MIT’s Initiative on the Digital Economy. “The people who know how to found and fund and…
