Isomorphic Labs’ $2.1B Series B (2026-05-12) dwarfs the next-largest disclosed round of $400M (Generalist AI, 2026-06-04), placing the top of the list in a steep size gradient: the next six largest entries range from $350M (TensorWave, 2026-06-10) down to $230M (Armada, 2026-05-19). Smaller rounds cluster tightly near the floor, with the smallest disclosed amount at $3M (Menou, 2026-06-01), illustrating a wide dispersion from ultra-large to single-digit millions.
Geographically, the page leans heavily toward major tech metros: New York appears in 7 entries and San Francisco in 5 (with Palo Alto appearing 3 times), suggesting hub concentration rather than a single-country pattern. Temporally, the 50 disclosed Series B rounds run from 2026-04-23 through 2026-07-14, with multiple large checks landing in mid-June (e.g., Odyssey $310M on 2026-06-17; SiliconFlow $296M on 2026-06-16; Sarvam AI $234M on 2026-06-15).

Frequently asked
What’s the largest disclosed Series B amount in this AI list, and how much bigger is it than the rest?
Isomorphic Labs leads with a disclosed $2.1B on 2026-05-12, and that figure dwarfs the next-largest disclosed round: $400M for Generalist AI on 2026-06-04. After that, the biggest remaining disclosed rounds sit much lower (e.g., TensorWave $350M on 2026-06-10; Odyssey $310M on 2026-06-17).
Do any cities appear disproportionately often among these Series B AI rounds?
New York is the most frequent city with 7 entries (including InstaLILY AI $60M on 2026-07-14 and Cinder Technologies $41M on 2026-05-12), while San Francisco follows with 5 entries (including OpenRouter $113M on 2026-05-26 is not SF, but Corgi Insurance $106M on 2026-05-28 and Monaco $50M on 2026-05-12 are). Palo Alto appears 3 times (e.g., Odyssey $310M on 2026-06-17; MainFunc/GenSpark $100M on 2026-06-11; Cowboy Space $305M on 2026-05-11 in San Carlos, with other Palo Altos also present).
Which rounds are most concentrated in the latest part of the date window?
The most recent round dates are 2026-07-14, with two disclosed Series B rounds: InstaLILY AI at $60M and eClear at $28M. Mid-June also concentrates larger checks, including Odyssey $310M (2026-06-17), SiliconFlow $296M (2026-06-16), and Sarvam AI $234M (2026-06-15).
Are there outlier deals in either direction that stand out from the typical disclosed amounts?
Yes on both ends: Isomorphic Labs’ $2.1B (2026-05-12) is an extreme upper outlier relative to the next-largest disclosed $400M (Generalist AI, 2026-06-04). On the low end, Menou’s $3M (2026-06-01) is the smallest disclosed amount in the dataset, below other small but still materially larger rounds like GreenCore Solutions’ $6M (2026-06-01) and KEMARO AG’s $5M (2026-04-23).
Is there evidence of a narrow time window for the smallest disclosed rounds?
Several of the smallest disclosed amounts cluster around early June: Menou is $3M on 2026-06-01, GreenCore Solutions is $6M on 2026-06-01, and KEMARO AG is $5M on 2026-04-23 (the earliest date shown). Compared with that, the very largest rounds appear later in mid-May to mid-June (e.g., Cowboy Space $305M on 2026-05-11; Generalist AI $400M on 2026-06-04).
