The final numbers are in. Crunchbase’s Q1 2026 venture report, published April 1, confirms that global startup investment reached between $297 billion and $300 billion across approximately 6,000 companies, the highest single-quarter total in the industry’s history. AI captured the overwhelming share. According to Crunchbase data, AI companies received between $239 billion and $242 billion, representing 80 to 81 percent of all global venture capital deployed in the quarter.
This brief is a follow-up to our earlier analysis, “$242 Billion to AI in One Quarter: What Q1 2026’s Capital Surge Means for the Industry.” That piece examined what the surge signals. This one reports what the completed data confirms.
The four deals that defined the quarter.
Four frontier lab transactions anchored the entire period. OpenAI raised $122 billion, already the largest venture round in history when it closed. Anthropic closed a $30 billion Series G. xAI raised $20 billion. Waymo secured $16 billion. Together, these four rounds totaled roughly $186 billion to $188 billion, representing approximately 64 percent of all global venture capital in Q1 2026, per that reporting. Four of the five largest VC rounds ever recorded closed in a single quarter.
A note on valuations: OpenAI’s round reportedly valued the company at $852 billion, and Anthropic’s Series G reportedly set a post-money valuation of $380 billion. Both figures have appeared across multiple trade publications. Neither has been confirmed against SEC filings or official company disclosures, and should be treated accordingly. GIC and Coatue have been reported as lead investors in Anthropic’s round, though this has not been confirmed in the available source content for this package.
What the concentration figure means.
Sixty-four percent of all global venture capital to four companies is not a funding story. It’s a concentration story. The remaining approximately 5,996 startups in Crunchbase’s tracked cohort shared the other 36 percent. That’s roughly $108 billion to $111 billion split across thousands of companies, still a substantial figure in historical terms, but one that recedes dramatically against the frontier lab totals.
For context: per Crunchbase data, Q1 2026 funding represents approximately 70 percent of the total venture capital deployed across all of 2025. The quarter-over-quarter and year-over-year increase was approximately 150 percent, according to Crunchbase’s figures.
What to watch.
Crunchbase’s Q1 report captures rounds that closed through March 31. It does not capture the second-order effects: how the capital gets deployed, what hiring or infrastructure decisions follow, and whether the pace holds into Q2. Anthropic’s reported lead investors, if confirmed, signal sovereign and institutional appetite for frontier AI exposure, which has implications for how the next tranche of rounds gets structured. Watch for Q2 preliminary data from Crunchbase and competing data providers in late June.
TJS synthesis.
The headline number is large. The concentration figure is the more significant data point. When four entities capture nearly two-thirds of global venture investment in a single quarter, the downstream dynamics, hiring patterns, infrastructure buildouts, competitive positioning for the remaining market, flow disproportionately through those four companies. The Q1 data doesn’t just confirm a record. It reveals how narrow the top of the AI capital stack has become.
