Investment in North American startups dropped to $92 billion in the third quarter, marking a 35% decline from the previous quarter but still 50% above year-ago levels, according to new data published by Crunchbase on October 2, 2026. The decline stems primarily from the absence of new megarounds for OpenAI and Anthropic rather than any broad deterioration in venture conditions, the report finds. Deal volume stayed relatively stable, with late-stage and early-stage round counts hovering near prior quarter levels.

Late-stage and growth-stage deals captured the lion's share of investment, pulling in $66.45 billion—up roughly a third from a year earlier but down sharply from the first and second quarters of 2026, when OpenAI and Anthropic secured financings worth $110 billion and $65 billion respectively. More than a dozen startups attracted late-stage or growth rounds exceeding $1 billion, led by Databricks at $5 billion, Crusoe at $3.9 billion, The Boring Co. at $3 billion, and Cognition at $2 billion. Early-stage investment totaled $20.6 billion, down from the prior quarter but still well above year-ago comparables, with standout rounds including River AI's $1.1 billion Series A, Valar Atomics' $660 million Series B, and Fab2's $500 million Series A. Seed-stage dealmaking reached at least $5 billion, slightly below both prior quarter and year-ago figures, though the total is expected to rise as additional seed deals are reported in coming weeks and months.

Artificial intelligence remained the dominant theme, with roughly two-thirds of total funding flowing to AI-focused companies, the report notes. A total of $61 billion went to AI-focused rounds in Q3, down sharply from the prior two quarters but still one of the highest tallies on record. On the exit front, acquisition activity proved fairly robust, boosted by a handful of large AI-related purchases including Nvidia's $12.93 billion acquisition of Hugging Face, AMD's $8.2 billion stock deal for World Labs, and Stripe's acquisition of OpenRouter for around $7.5 billion—bringing the quarter's total to 11 North American startup acquisitions at reported prices of $1 billion or more. The IPO market was quieter, with 17 venture-backed North American companies going public on major U.S. and Canadian exchanges and collectively raising just under $4 billion, mostly in biotech, energy, and consumer-facing offerings.

The report characterizes Q3 as exemplifying how funding activity can decline from peak levels without clear indication that the investment climate has turned bearish. The maturation of the two most valuable startups—OpenAI and Anthropic—into even more valuable pre-IPO companies is precisely what venture investors want to see, the authors write. Big rounds continue closing at a brisk clip, the AI space is still regularly minting fresh unicorns, and acquirers are snapping up leading names at historically high valuations. The report notes that much of the market's attention is looking forward to enormous offerings from foundational AI pioneers in coming months, with Anthropic reportedly eyeing a public listing as early as November and OpenAI expected to debut in 2027 after filing confidentially for an IPO in June. For now, the AI-driven momentum continues. Investors betting heavily on the artificial intelligence wave may face concentration risk if the sector's fundamentals shift, while companies outside the AI spotlight could struggle to attract comparable capital even with strong fundamentals.
