PitchBook's first-half 2026 data confirms what the mega-round headlines have been suggesting all year: US venture funding hit a record $412.7 billion, up nearly 30% from the pace of all of 2025, and AI-focused companies alone captured $355.9 billion of that total -- 86 cents of every venture dollar deployed. Crunchbase's independent global tally, at a record $510 billion for the half versus $440 billion for the entirety of 2025, corroborates the scale of the surge even if its methodology differs slightly.
What's less discussed than the headline totals is what's happening beneath them: the number of individual deals has fallen even as total dollars have surged, meaning the market is concentrating larger checks into fewer companies rather than broadening participation. North American startup funding and M&A activity both set records in the same window, and that combination -- more capital, fewer deals, more exits -- describes a market that's simultaneously the best-funded and the most selective it's been in years.
“The concentration isn't just happening at the company level.”
The concentration isn't just happening at the company level. Fund-level data shows the five largest venture managers captured 73.1% of all capital raised industry-wide in the period, and the top 15 captured 88.5% -- meaning LP dollars are consolidating into a small number of brand-name funds at almost exactly the same rate that company-level dollars are consolidating into AI. Two separate concentration effects, compounding at the same time, in the same direction.
For emerging managers and smaller funds, this is the uncomfortable subtext behind an otherwise triumphant H1: raising a new fund in this environment increasingly means competing directly against a handful of megafunds for LP allocation, in a market where LPs themselves are consolidating commitments into fewer relationships. For founders outside the AI-labeled 86%, it means the remaining 14% of venture dollars is being fought over by every non-AI category combined -- fintech, biotech, climate, consumer -- a genuinely harder fundraising environment than the record headline totals suggest.
The bear case: concentration this extreme, at both the company and fund level, is a classic late-cycle signal -- when 86% of dollars chase one category and 73% of capital sits with five managers, the market has very little room left to broaden before a correction forces it to. What to watch next: whether H2 2026 data shows any softening in the AI concentration ratio, and whether emerging managers outside the top 15 report materially harder fundraising conditions in their own LP conversations.
