North American startups raised $92 billion in the third quarter of 2026, down 35% from the prior quarter but up 50% from a year earlier, according to Crunchbase data as of Oct. 2. Artificial intelligence companies captured roughly two-thirds of that total, or $61 billion, keeping AI the dominant theme for investors. The sequential drop reflects the absence of giant financings for OpenAI and Anthropic, not a broad weakening of venture activity, with deal volume holding steady.
Late-stage rounds and AI deals behind the $92 billion
Late- and growth-stage deals accounted for $66.45 billion in Q3, up about a third year over year but sharply below the first two quarters, when OpenAI raised $110 billion and Anthropic raised $65 billion. The largest rounds went to Databricks at $5 billion, Crusoe at $3.9 billion, The Boring Co. at $3 billion, and Cognition at $2 billion. More than a dozen startups closed late-stage or growth rounds of $1 billion or more, showing that very large checks continued without the two foundation-model leaders.
Early-stage investment totaled $20.6 billion, down sequentially from a multiyear peak in the prior quarter yet still well above year-ago levels. The tally was lifted by several outsized rounds, including River AI with a $1.1 billion Series A, Valar Atomics with a $660 million Series B, and Fab2 with a $500 million Series A. Seed, angel and pre-seed funding reached at least $5 billion on preliminary data, slightly below prior comparisons, although Crunchbase expects the figure to rise as late-reported deals are added. Physical AI startups stood out at seed, with Walden Robotics raising $300 million and Veeda AI securing $90 million.
The quarter fits a pattern in which headline funding falls from peaks while underlying activity stays firm. Late-stage and early-stage round counts remained close to prior-quarter levels, and AI funding, though down from the prior two quarters, still ranked among the highest totals on record. The comparison was shaped by Q2, which included SpaceX's record market entry and Anthropic's large financing. Crunchbase notes that reported data cover seed- through growth-stage rounds for U. S. and Canadian startups, with values in U. S. dollars and seed totals subject to reporting lags.
What exits and IPO plans mean for AI business
For companies buying or building AI products, the funding mix points to continued supply of infrastructure, models and coding tools from well-capitalized vendors. Databricks, Crusoe, Cognition, River AI and Fab2 all closed rounds of $500 million or more, which supports product development and enterprise sales capacity. Small firms gain access to a wider set of funded tools, while large firms face a vendor landscape where a few AI infrastructure providers hold substantial capital and negotiating power.
The exit picture requires careful reading before drawing conclusions about valuations or timing. The IPO market was sluggish, with 17 venture-backed North American companies raising just under $4 billion, led by Adarx Pharmaceuticals, Braveheart Bio and Electra Therapeutics, plus Standard Nuclear and Lime. M&A was stronger, with 11 startup acquisitions at $1 billion or more, topped by Nvidia's $12.93 billion purchase of Hugging Face, AMD's stock deal around $8.2 billion for World Labs led by Fei-Fei Li, and Stripe's August deal around $7.5 billion for OpenRouter. The largest future signal sits outside Q3: Anthropic is reportedly eyeing a listing as early as November, while OpenAI filed confidentially in June for an expected 2027 debut.
The marker to watch is whether those two listings proceed on schedule and at what scale, alongside the pace of billion-dollar private rounds. If Anthropic lists in November and OpenAI moves toward 2027 while large AI rounds keep closing, the current structure of concentrated private capital shifting toward public markets will be confirmed. For business, that shift would define pricing, partnership stability and procurement risk around core AI suppliers.
