A historic quarter for venture funding masks a stark reality: the market has never been this concentrated, with a handful of US artificial intelligence companies absorbing the vast majority of global capital.
Q1 2026 shattered venture capital records with $267 billion in funding — but 4,589 startups shared just $77 billion of it. The other $190 billion went to five companies only: OpenAI, Anthropic, xAI, Waymo and ViiV Healthcare.
Global venture capital investment reached $267 billion in the first quarter of 2026, approaching the total raised across all of 2025, according to data from KPMG’s Venture Pulse and PitchBook’s joint report with the National Venture Capital Association (NVCA). The headline figure points to renewed enthusiasm in the sector — but a closer look reveals a market defined less by breadth than by extreme concentration.
According to the PitchBook from the National Venture Capital Association (NVCA) Venture Monitor, the top five deals alone accounted for 73% of all US venture capital deployed in Q1. When the lens widens to include all AI-related transactions, that share jumps to 88.8% — meaning nearly nine out of every ten venture dollars in America went to artificial intelligence companies.
As previously analyzed in High Interest Rates Anchor Brazilian Venture Capital Amid US AI Surge, the AI venture boom remains heavily concentrated in the United States, with limited participation from Asia and with other markets including Europe, Latin America yet to see comparable levels of risk appetite and investment activity.

Five Deals. $190 Billion. One Quarter.
According to Crunchbase data compiled in May 2026, the five largest venture rounds of the quarter were:
| Company | Round | Amount | Date |
|---|---|---|---|
| OpenAI | Venture Round | $122.0B | Feb 27 2026 |
| Anthropic | Series G | $30.0B | Feb 12 2026 |
| xAI (Grok) | Series E | $20.0B | Jan 6 2026 |
| Waymo | Series D | $16.0B | Feb 2 2026 |
| ViiV Healthcare | Corporate Round | $2.1B | Jan 20 2026 |

OpenAI’s $122 billion raise alone — the largest single venture financing in history — represents nearly half of all Q1 deal value. Together, the five rounds total approximately $190 billion, leaving just $77 billion for the remaining 4,589 companies that also closed deals during the quarter. To put that disparity in concrete terms: five companies averaged $38 billion each, while the rest of the market averaged roughly $16.8 million per deal — a ratio of more than 2,000 to one. Remove those five deals entirely, and total Q1 venture investment collapses by 73%. The record-breaking quarter, in other words, was not a rising tide — it was five very large boats.
| Metric | Top 5 Companies | Remaining Market |
|---|---|---|
| Number of deals | 5 | ~4589 |
| Total capital raised | $190.1B | $77.1B |
| Share of Q1 total | 73.2% | 26.8% |
| Average deal size | $38.0B | $16.8M |
Average deal size for the remaining market is calculated by dividing $77.1B across an estimated 4,589 deals. The 2,000-to-1 ratio between average deal sizes illustrates the historic nature of Q1 concentration. Source: PitchBook-NVCA Venture Monitor Q1 2026; Crunchbase, as of May 21, 2026

Valuations Surge — But Only at the Top
The AI concentration effect is equally visible in valuation data. According to KPMG’s Venture Pulse, median pre-money valuations for Series D+ companies reached $2.4 billion in Q1 2026, up from roughly $850 million in 2025 — a near-tripling in a single year, driven by the wave of late-stage AI mega-rounds.
Earlier-stage companies tell a different story. While Series A and B valuations have risen steadily since 2020, the acceleration seen at the later stages has not materialized at the seed or early stage in the same way, pointing to a market where the valuation premium is concentrated among perceived category leaders rather than distributed across the ecosystem.
The gap between AI and non-AI companies sharpens that picture further. At Series A, AI startups command a median pre-money valuation of $78 million versus $42 million for non-AI peers — a premium of roughly 2x. By Series D+, that gap expands dramatically: AI companies are valued at a median of $4.7 billion, compared to $1.3 billion for non-AI equivalents — more than a 3.5x difference.

A Market of Two Halves
The record numbers paint a picture of a venture market firing on all cylinders. The reality beneath the surface is more complex. Liquidity remains tight for most startups, the IPO window has not meaningfully reopened, and emerging fund managers are finding capital increasingly scarce as limited partners concentrate commitments in established names.
For markets outside the United States, the gap is widening. The AI investment supercycle appears, for now, to be an American story — one written in nine and ten-figure checks, flowing to a small number of companies building the infrastructure of the next technological era.
