Seven Billionaire-Led Startups Took More Than Half of U.S. VC

By Olivia Hart

Seven companies raised more than $260 billion in equity in the first 10 months of 2025. According to Crunchbase data, they took just over 50% of U.S. seed-through-growth-stage investment, leaving the rest of the market with less than half.

The group comprised:

• OpenAI
• Anthropic
• xAI, now part of SpaceX
• Anduril Industries
• Databricks
• Prometheus
• The Boring Co.

That concentration favors ventures founded or led by billionaire men, according to Crunchbase News. The finding describes dollar concentration, not the number of venture recipients or their prior wealth.

Which founders anchor the seven-company funding bloc?

Crunchbase News identified Elon Musk and Jeff Bezos as the world’s wealthiest men. The report said Musk founded xAI and The Boring Co. and co-founded OpenAI, although he has no known equity stake in the latter. Outside investors funded those companies; Crunchbase News noted that Musk could have financed them himself.

Crunchbase News reported that Bezos launched the physical AI startup Prometheus in 2025. It raised $12 billion earlier that year, while Bezos’s calculated net worth exceeded $350 billion.

Takeaway: The funding bloc includes founders made wealthy by current valuations and founders already wealthy enough to fund their own companies.

Where did the AI founders’ wealth come from?

Crunchbase News ranked OpenAI and Anthropic as the two highest-valued startups and described Anthropic as soon to be public. Both companies had prominent billionaire founders and CEOs, but the report described their wealth paths as mixed.

OpenAI co-founder and CEO Sam Altman built the bulk of his wealth through Y Combinator investments, including Stripe and Reddit. Altman has said he “does not have an equity stake in OpenAI beyond a sliver from an old YC round.”

Crunchbase News reported that co-founder Greg Brockman holds a larger OpenAI stake, reportedly valued around $30 billion earlier in 2025.

At Anthropic, all seven co-founders have similar-sized equity stakes worth billions each, according to Crunchbase News. The group includes co-founder and CEO Dario Amodei.

Takeaway: Billionaire status among leading AI companies comes from different combinations of current equity, investments and earlier deals.

What do the data and defense companies show?

Databricks and Anduril Industries both have founder-CEOs whose net worths exceeded $1 billion during their tenures, according to Crunchbase News.

Crunchbase News reported a $7.6 billion net worth for Databricks co-founder and CEO Ali Ghodsi. The company carried a valuation of around $190 billion after an August 2025 financing.

Anduril co-founder and CEO Brian Schimpf has an estimated $1.5 billion net worth from his stake in the defense industry disruptor, which carried a $61 billion valuation, according to Crunchbase News.

Co-founder Palmer Luckey sold his virtual reality startup Oculus to Meta for $2 billion in 2014 before starting Anduril. Crunchbase News estimated his net worth at $5.9 billion.

Several founders and CEOs behind other large 2025 rounds were billionaires too, according to Crunchbase News. They included Wonder founder Marc Lore, Figure founder Brett Adcock, and Surge AI founder and CEO Edwin Chen.

Takeaway: The data and defense companies show two routes to billionaire founder status: equity in the funded company and wealth from earlier exits.

Is the venture archetype changing?

Crunchbase News divides these billionaires into two groups. Ghodsi, Amodei and Brockman became billionaires through the startups that raised capital, while Musk, Bezos, Altman and Luckey arrived with billions from prior companies or investments.

Luckey became a billionaire at 21 after the Oculus sale, according to Crunchbase News.

Crunchbase News said neither billionaire group commonly received venture rounds historically. It traced the term “unicorn,” meaning a private company valued at $1 billion or more, to 2013, when the asset class became noticeably large.

In prior decades, founders and CEOs mostly became billionaires only after their startups went public or sold in high-priced acquisitions, according to Crunchbase News.

Capital still reaches stereotypical venture recipients, including first-time founders and serial entrepreneurs whose earlier companies did not make them fabulously wealthy. But Crunchbase News found that a majority now goes to companies with valuations high enough to make stakeholders billionaires or to ventures founded by already-billionaire men.

Still, the published figures do not disclose round counts, median checks or a like-for-like historical share of billionaire founders. The dollar totals establish concentration at the top; they do not show that most venture recipients are billionaires.

Takeaway: Anthropic’s planned public listing will test whether new funding spreads more widely or stays concentrated among billionaire-led companies.
