Venture funding concentrates
Venture capital is narrowing around a few big winners: AI captured an outsized share of US venture dollars in March and observers say the industry is becoming more concentrated around platform-scale companies. (axios.com) (alleywatch.com)
United States venture capital is piling into a handful of giant companies, with artificial intelligence taking 60.1% of all startup funding in March 2026. (alleywatch.com) AlleyWatch counted $19.06 billion across 630 United States venture deals in March, including $11.46 billion for artificial intelligence companies across 316 deals. Shield AI raised $2.0 billion, Saronic raised $1.75 billion, and Mind Robotics raised $500 million. (alleywatch.com) The pattern was even sharper over the full first quarter. PitchBook and the National Venture Capital Association said United States startups raised $267.2 billion in the first three months of 2026, but that total drops 73.2% if the five biggest deals are excluded. (pitchbook.com) One of those deals was OpenAI’s March 31 round: $122 billion in committed capital at an $852 billion post-money valuation. OpenAI said Amazon, Nvidia, SoftBank, Microsoft, Andreessen Horowitz, TPG, MGX, and T. Rowe Price-backed accounts were among the backers. (openai.com) PitchBook said concentration had already defined the post-pandemic venture market, but the first quarter of 2026 marked “a new extreme.” Axios reported that if those five transactions are stripped out, United States venture investment actually fell quarter over quarter. (pitchbook.com) (axios.com) The money is also clustering around companies that need huge amounts of computing power, chips, and data centers rather than the smaller software startups that once dominated venture portfolios. OpenAI said “durable access to compute” is now a strategic advantage, and PitchBook said artificial intelligence continues to dominate the market. (openai.com) (pitchbook.com) That leaves a split market underneath the headline numbers. PitchBook said the median internal rate of return for North American venture fund vintages since 2019 remains in the single digits, and the median distribution-to-paid-in multiple for vintages from the past decade is still below 1x. (pitchbook.com) Fund managers are responding by steering more money to established names. In PitchBook’s Q1 2026 webinar, the firm said five venture firms accounted for nearly 73% of total fundraising for the quarter as limited partners favored “name-brand, established managers” over emerging firms. (pitchbook.com) March still spread money across more cities than a typical venture month, with New York taking 20.7% of national capital, San Diego 11.3%, Palo Alto 10.5%, Austin 10.4%, and San Francisco 10.1%. But the biggest checks kept going to a narrow set of late-stage companies, not a broad startup field. (alleywatch.com) The result is a venture market posting record totals while behaving less like a wide funnel for new startups and more like a financing machine for a few platform-scale winners. PitchBook’s warning for 2026 was blunt: “Now more than ever, the only certainty in VC is uncertainty.” (pitchbook.com)
