Q1 AI funding concentrates

Private artificial intelligence funding did not spread evenly in the first quarter of 2026. One OpenAI deal swallowed more than half of the quarter’s total, according to CB Insights. (cbinsights.com) CB Insights said private artificial intelligence companies raised $226 billion in the quarter, and roughly 54% of that came from a single OpenAI minority round. Its separate venture report said OpenAI’s $122 billion raise accounted for 43% of all global venture funding in the quarter. (cbinsights.com 1) (cbinsights.com 2) OpenAI closed that round on March 31 at an $852 billion post-money valuation, up from the $110 billion figure it had announced in February. CNBC reported the final round included $122 billion of committed capital, with SoftBank, Andreessen Horowitz, D. E. Shaw Ventures, Microsoft, and retail investors participating. (cnbc.com) SoftBank said on February 27 that it alone agreed to invest $30 billion through SoftBank Vision Fund 2 at a $730 billion pre-money valuation. OpenAI said the funding would help it scale infrastructure, and it separately announced expanded partnerships with Amazon and Nvidia. (group.softbank) (openai.com) The pattern was not limited to OpenAI. CB Insights said $100 million-plus mega-rounds made up 86% of all venture funding in the quarter, while global deal count fell to just under 7,000, the lowest quarterly total since the fourth quarter of 2016. (cbinsights.com) Crunchbase’s separate tally pointed in the same direction, even though its totals were higher. Crunchbase said global startups raised $300 billion in the quarter, with $242 billion going to artificial intelligence companies and four giant rounds — OpenAI, Anthropic, xAI, and Waymo — totaling $188 billion. (news.crunchbase.com) That leaves the market looking bigger on paper and narrower in practice. CB Insights said early-stage deals fell to 64% of total deals from 68% a year earlier, while the active investor pool kept shrinking. (cbinsights.com) OpenAI’s scale helps explain why investors wrote such large checks. CNBC said ChatGPT had more than 900 million weekly active users and more than 50 million subscribers as of March, while OpenAI said the new financing would support faster, more reliable service at global scale. (cnbc.com) (openai.com) The quarter’s headline number was a funding boom. The underlying shape was concentration: fewer deals, fewer investors, and more of the money going to a handful of companies building the biggest models and the data centers to run them.
