Funding for artificial intelligence (“AI”) companies totaled $103.3 billion globally in Q3 2026, according to CB Insights’ report State of AI Q3’26. That figure is down 33% from Q2’s $153.1 billion and well below Q1’s record $239.1 billion, but it is still the third-largest quarter in the report’s data set and higher than any quarter before 2026. Year-to-date 2026 funding has reached $495.6 billion, already about 82% over full-year 2025 funding of $272.6 billion. Deal volume fell 21% from the second quarter to 2,180 deals, bringing the total number of AI deals in 2026 to 8,242. Deals in the United States continued to lead, capturing $63.0 billion, or approximately 61% of global funding, in 1,079 deals. Yet U.S. dominance in private funding has not carried over to the public markets. U.S. AI companies accounted for just two of the quarter’s 19 IPOs, while Chinese AI chip and robotics companies led the quarter’s listings.
Mega-rounds and concentration
Private rounds now rival or exceed most public offerings in size. Mega-rounds contributed $87.9 billion in 154 deals, representing 85% of quarterly funding. The four largest rounds alone totaled $23.9 billion, or nearly a quarter of all funding: OpenAI ($10 billion), Databricks ($5 billion Series L), Safe Superintelligence ($5 billion corporate minority round led by NVIDIA) and Crusoe ($3.9 billion Series F). Mega-rounds accounted for 79% of funding in Q4 2025 and 91% in Q1 2026, compared with roughly 44% in 2022. The largest AI companies can keep raising private capital at public-company scale, which pushes back the need for, and the timing of, an IPO.
Late-stage deals
Early-stage startups continue to account for most transactions, at 73% of AI deals year-to-date, while late-stage deals account for 7%. Late-stage companies, however, are raising much larger rounds. The median late-stage round rose to $82.5 million in 2026, up from $50.0 million in 2025, and the median mid-stage round rose to $44.2 million from $30.5 million. Notable late-stage rounds included Mistral’s $3.5 billion Series D ($24.4 billion valuation), Moonshot AI’s $3.5 billion Series E ($35.0 billion), Cognition’s $2.0 billion Series E ($48.0 billion), Helsing’s $1.8 billion Series E ($18.0 billion) and Harvey’s $550 million Series H ($15.6 billion).
Unicorns
Unicorn creation accelerated again. Forty-two new unicorns were minted in Q3, the highest in 18 months, bringing the global total to 706. The U.S. led with 24 new unicorns, followed by Asia with 11 and Europe with 7.
Exits
U.S. companies captured 61% of funding and 470 of the world’s 706 unicorns, but contributed only two of the quarter’s 19 IPOs. The three largest Chinese IPOs had a combined almost $27 billion exit value, which CB Insights notes matched the U.S. total—these include Enflame ($9.1 billion), Unitree Robotics ($9.0 billion) and Momenta ($8.9 billion). Other top IPOs came from Israel (XTEND, $1.5 billion), India (ESDS Software Solution, $532 million) and the UK. On the M&A front, there were 372 exits in Q3.

AI sectors in focus
Many of the largest rounds went to AI infrastructure and “neocloud” businesses rather than model developers or applications. Examples include Crusoe ($3.9 billion), Nscale ($2.4 billion via convertible note), Fluidstack ($1.5 billion Series B), Firmus in Australia ($2.0 billion) and Helix Digital Infrastructure ($1.0 billion from Samsung affiliates). Chip designers Positron ($875 million), Etched ($700 million Series D and $300 million Series C) and Groq ($350 million) also raised significant rounds. Robotics featured heavily at every stage. In addition to Unitree Robotics’ $9.0 billion IPO, Q3 saw XPeng Robotics’ $900 million Series A and unicorn debut, Sharpa’s $669 million round, D-Robotics’ $400 million Series C, and large seed rounds. These capital intensive businesses are natural candidates for convertible, structured equity and, eventually, public debt and equity financings.
