Seven Companies Run by Billionaires Absorb Over Half of U.S. Venture Funding

Just seven companies captured more than half of all U.S. seed- through growth-stage venture investment this year — and every one of them was founded or led by a billionaire, according to Crunchbase data.

The seven — OpenAI, Anthropic, xAI (now part of SpaceX), Anduril Industries, Databricks, Prometheus and The Boring Co. — raised more than $260 billion in equity funding in the first 10 months of the year. That works out to just over 50% of total U.S. seed and venture investment over the same period.

The founders and CEOs behind them are a familiar roster: Elon Musk, Jeff Bezos, Sam Altman, Dario Amodei and Palmer Luckey among them.

Who's behind the seven biggest fundraisers?

Two founders stand out: Musk and Bezos, the world's wealthiest men.

Musk founded xAI and The Boring Co., and co-founded OpenAI — though he holds no known equity stake in the latter. Outside investors funded these companies, but as the Crunchbase analysis notes, Musk could have afforded to fund them himself.

Bezos fits the same pattern. In 2025 he launched Prometheus, a physical AI startup that raised $12 billion earlier this year. Bezos' own net worth exceeds $350 billion.

How did the AI chiefs get rich?

The two highest-valuation startups — OpenAI and the soon-to-be-public Anthropic — also have billionaire founders and CEOs, but with mixed backstories.

OpenAI co-founder and CEO Sam Altman built his wealth primarily through investments in Y Combinator startups, including Stripe and Reddit. Altman has said he holds no equity in OpenAI beyond a sliver from an old YC round. Co-founder Greg Brockman holds a larger stake, reportedly valued around $30 billion earlier this year.

At Anthropic, all seven co-founders hold similar-sized equity stakes, each worth billions. That includes CEO Dario Amodei.

What about Databricks, Anduril and the rest?

Databricks and Anduril both have founder-CEOs who crossed the billion-dollar threshold during their tenures.

Databricks co-founder and CEO Ali Ghodsi has a reported net worth of $7.6 billion. The company hit a valuation of roughly $190 billion following an August financing.

Anduril co-founder and CEO Brian Schimpf holds an estimated $1.5 billion net worth through his stake in the defense-tech company, valued at $61 billion. Co-founder Palmer Luckey — who sold his VR startup Oculus to Meta for $2 billion in 2014 and became a billionaire at 21 — is now worth an estimated $5.9 billion.

Other founders behind this year's largest rounds are billionaires too, including:

• Marc Lore, founder of Wonder
• Brett Adcock, founder of Figure
• Edwin Chen, founder and CEO of Surge AI

Two kinds of billionaire founders

Crunchbase splits the group into two categories: billionaires made by the startup that just raised capital, and billionaires made by prior companies or investments.

Ghodsi, Amodei and Brockman belong to the first group. Musk, Bezos, Altman and Luckey belong to the second.

Historically, neither type was a common venture funding recipient. The term "unicorn" for private companies valued at $1 billion or more only entered the lexicon in 2013. In prior decades, founders typically reached billionaire status only after an IPO or a high-priced acquisition.

Does this change what venture capital is for?

Plenty of capital still flows to the stereotypical recipients — first-time founders or serial entrepreneurs whose earlier companies didn't make them rich. But they no longer get the majority of it.

Instead, most venture funding now goes to companies already valued high enough to make their stakeholders billionaires, or to ventures launched by men who were billionaires before they raised a dollar.

If the concentration holds, the classic image of the venture-backed founder — the scrappy outsider raising a first check — describes a shrinking share of where the money actually goes.
