In 2025, just six companies vacuumed up $90 billion in venture funding. Let that sink in for a moment. That’s more than what roughly 6,000 other startups collectively raised last year in sub-$100 million rounds. And the gap is only widening.
According to freshly crunched data from Crunchbase, 2025 marked the most concentrated year for U.S. venture capital on record. A staggering 70% of all U.S. funding — north of $200 billion — went to just 389 companies that raised rounds of $100 million or more. The remaining 30% ($88 billion) was split among approximately 6,000 companies running on rounds between $1 million and $100 million.
To put that in perspective: the average $100M+ company raised over $500 million last year, while the average startup in the rest of the market raised roughly $14.6 million. That’s not a gap — that’s a canyon.
It’s Worse Than 2021
You might remember 2021 as the peak of “ZIRP insanity” — the year startups raised money like it was going out of style. Back then, 60% of capital went to rounds of $100M or more. In 2025, that number hit 70%. But here’s the kicker: in 2021, most of that mega-round money was spread across 770 companies in the $100M–$500M range. In 2025, it shifted heavily upward — the bulk went to just 50 companies in rounds exceeding $500 million.
That changes the calculus completely. It’s not just that the rich are getting richer. The game itself has changed. The winners aren’t just raising big rounds — they’re raising generational war chests that fund an entirely different level of ambition.
2026 Is Even More Extreme
Through the first four months of 2026, U.S. venture totals are already pacing to match all of 2025. And the concentration is accelerating: 80% of all startup investment this year has gone to rounds of $500 million or more, spread across just 29 companies.
If you’re a founder outside the top tier, the message is unambiguous: the fundraising environment for everyone else isn’t getting easier — it’s getting more compressed.
But There’s a Silver Lining
Here’s the counterintuitive part: the sub-$100M market didn’t shrink in 2025. It actually grew by about $8 billion year-over-year, funding roughly the same number of companies. Only the smallest tier — rounds between $1M and $10M — saw a slight dip (under 10%). So while the headlines are dominated by nine-figure raises, the early-stage market isn’t dying. It’s just… biding its time.
Speaking during a Crunchbase News panel, Daniel Docter of Dell Technologies Capital noted that giants like OpenAI and Anthropic, by virtue of their massive capital raises, are forced to chase massive markets. “There’s just so much white space around that, where really interesting founders and startups can play,” he said.
Madison Faulkner, a partner at NEA, echoed that sentiment: “This is a moment where I’m extremely excited about betting on seed and Series A, especially in spaces that compete with Anthropic and OpenAI. They’ve really struggled to focus, and they’ve been spending so much time trying to win lots of different use cases.”
In other words: while the hyperscalers fight over the entire ocean, there are plenty of fish in the coves.
What Founders Should Actually Do
This concentration trend isn’t a bug — it’s a feature of how AI is reshaping venture. The capital-efficient playbook has changed. Here are the takeaways:
- Don’t compete head-on with the giants. Find the white space where they can’t focus. Build deep into a specific workflow, own a proprietary data moat, and make yourself indispensable to a vertical.
- Defensibility comes from depth, not scale. As 645 Ventures co-founder Nnamdi Okike puts it: “If you’re very deeply embedded into a company’s workflow, where you’re doing many different tasks, not to mention you’re assembling a proprietary corpus of data — that can be a sustainable moat over time.”
- Raise smart, not big. The sub-$100M market is still alive and well. Focus on capital efficiency and traction over vanity metrics. The next wave of breakout companies won’t be built on $500M raises — they’ll be built on focus.
- Know that the tide lifts some boats. The success of the mega-companies expands the total addressable market for the entire tech ecosystem. More AI adoption means more startups solving the problems that emerge around those systems.
The Bottom Line
Venture capital is concentrating at the top, and that trend isn’t reversing anytime soon. But for founders paying attention, the opportunity is in the white space — not in trying to out-muscle the giants, but in building something they can’t afford to focus on. The next great startup won’t win by raising the biggest round. It’ll win by being the most indispensable solution in a market worth fighting for.
