The 50 most recent Series C rounds in artificial intelligence span November 2025 back to January 2025, with California-headquartered companies accounting for roughly half the entries. San Francisco alone hosts nine of the 50, including Cognition ($500M, August 2025), Anysphere ($900M, June 2025), and Ambience Healthcare ($243M, July 2025). Palo Alto contributes four more — Harmonic ($120M), Luma AI ($900M), Hippocratic AI ($126M), and Modular ($250M), all closed between September and November 2025.
The two largest disclosed rounds belong to Mistral AI in Paris ($2.0B, September 2025) and Figure in Sunnyvale ($1.0B, September 2025). Healthcare AI, AI inference infrastructure, and physical robotics each appear as dense clusters within the set — Hippocratic AI, Ambience Healthcare, and Brainomix on one side; Fireworks AI, d-Matrix, and Baseten on another; Figure, Dexory, and Machina Labs on a third. Four rounds — Polymarket, Replit, Machina Labs, and Anumana — closed without disclosed amounts.

Frequently asked
What are the largest disclosed Series C rounds among these AI companies?
Mistral AI (Paris) leads at $2.0B, closed September 2025, followed by Figure (Sunnyvale) at $1.0B the same month. Luma AI and Anysphere both raised $900M — in November and June 2025, respectively — with Saronic ($600M, Austin, February 2025) and Cognition ($500M, San Francisco, August 2025) rounding out the top six disclosed amounts.
Which cities have the highest concentration of Series C AI companies in this list?
San Francisco leads with nine companies, including Mercor, Decagon, Laurel, and Anysphere. Palo Alto follows with four — Harmonic, Luma AI, Hippocratic AI, and Modular. New York accounts for five entries, among them Kalshi, Tennr, and Viam.
Is there meaningful international Series C activity in AI, or is it concentrated in the US?
Fourteen of the 50 companies are headquartered outside the US, spanning Paris (Mistral AI at $2.0B, Nabla at $70M), Stockholm (Legora at $150M), Berlin (Parloa at $120M), and London (Dexory at $100M), with additional entries from Israel, India, Australia, Canada, Hungary, and the Netherlands.
Which AI sub-sectors appear most frequently across these Series C rounds?
Healthcare AI is the largest cluster, with eight companies including Hippocratic AI, Ambience Healthcare, Navina, Brainomix, Nabla, Anumana, Rad AI, and Harrison.ai. AI infrastructure and inference — Fireworks AI, Baseten, d-Matrix, Celestial AI, and Modular — forms a second dense group, alongside four physical-world robotics companies: Figure, Starship Technologies, Dexory, and Machina Labs.
How small do Series C rounds get in this AI dataset?
The two smallest disclosed rounds are Motion ($8M, Sacramento) and Rad AI ($8M, San Francisco), both well below the typical Series C range. Harrison.ai in Australia ($20M) and Brainomix in Oxford ($18M) also sit at the lower end, suggesting that AI diagnostics and healthcare companies outside major US funding hubs can close Series C rounds at significantly smaller check sizes.
When did most of these AI Series C rounds close?
October and November 2025 account for twelve of the fifty rounds, including Luma AI ($900M), d-Matrix ($275M), and Suno ($250M). September 2025 adds seven more, headlined by Mistral AI ($2.0B) and Figure ($1.0B), making the second half of 2025 the most active window in the dataset.
