The disclosed Series C rounds show a pronounced size outlier: Nscale’s $2.0B (2026-03-09) is the only entry above $900M, and it dwarfs the next few disclosed rounds that top out at Skild AI’s $1.4B (2026-01-14), Luma AI’s $900M (2025-11-22), and Waabi’s $750M (2026-01-28). Most other disclosed rounds cluster far lower, with the smallest disclosed amount at Brainomix’s $7M (2026-02-24), making the spread between extremes wide even within a single stage.
Geographically, concentration is visible: San Francisco appears in 9 rows and New York in 6, with London showing 4 entries, including multiple Series C rounds around mid-2026 (e.g., PhysicsX on 2026-06-08 and 9fin on 2026-03-31). Temporally, the span runs from 2025-10-27 to 2026-07-14, and the most recent month includes several large disclosures such as Chai Discovery’s $400M (2026-07-14) and Norm AI’s $120M (2026-07-07), while two rows remain undisclosed (e.g., Automata on 2026-06-25).

Frequently asked
What’s the largest disclosed Series C round in this AI list, and how concentrated are the top few?
The largest disclosed round is Nscale at $2.0B (2026-03-09). The next-largest disclosed amounts step down to Skild AI ($1.4B on 2026-01-14), Luma AI ($900M on 2025-11-22), and Waabi ($750M on 2026-01-28), after which the top end drops to $400M or below (e.g., Chai Discovery $400M on 2026-07-14).
Which cities appear over-represented in these Series C AI rounds?
San Francisco is the most frequent city with 9 entries, followed by New York with 6 and London with 4. Examples include San Francisco listings such as Chai Discovery ($400M on 2026-07-14) and Mercor ($350M on 2025-10-30), New York listings like Norm AI ($120M on 2026-07-07) and Standard Bots ($200M on 2026-06-09), and London listings like PhysicsX ($300M on 2026-06-08) and 9fin ($170M on 2026-03-31).
How tight is the recent timing, and what do the temporal edges indicate?
Rounds in this view run from 2025-10-27 (oldest: Legora $150M on 2025-10-27) through 2026-07-14 (most recent: Chai Discovery $400M on 2026-07-14). The clustering near the top of the range is visible with multiple June 2026 entries (e.g., PhysicsX $300M on 2026-06-08, Dream Security $260M on 2026-06-18, and Chai Discovery’s $400M in July).
Are there notable outliers on the low end compared with the smallest disclosed rounds?
Yes. The smallest disclosed amount is Brainomix at $7M (2026-02-24), which sits far below the next tier of disclosed rounds such as Subtle Medical at $33M (2026-06-02) and Bland AI at $50M (2026-06-16). In contrast, the largest disclosed rounds (Nscale $2.0B and Skild AI $1.4B) occupy the extreme top end of the disclosed range.
How do undisclosed amounts affect comparisons of scale in the list?
Two of 50 rows are undisclosed (Automata on 2026-06-25 and CAST AI on 2025-12-11). Comparisons of “largest” and “smallest” are therefore based on the 48 disclosed entries, including the top-ranked $2.0B (Nscale) and the bottom disclosed $7M (Brainomix).
