Within the 50 most recent AI rounds listed for San Francisco, the largest disclosed amount is Baseten’s $1.5B on 2026-06-22, which dwarfs the next tier of large financings (e.g., Mirendil at $200M on 2026-06-24, Assort Health at $120M on 2026-06-24, and Smartbird at $100M on 2026-06-17). At the other end, the smallest disclosed amount shown is $500K, repeatedly appearing across many Pre-Seed entries dated 2026-06-16 (e.g., ProvenMetal, Arden, Arzana, jo, and many others).
The list is also temporally clustered: most entries concentrate in a narrow window around 2026-06-16 to 2026-06-25, culminating with the most recent dated round on 2026-06-30 (Derya at $1M). Stage labeling is mixed, with “Series Unknown” appearing 3 times (Engine Biosciences, Kled AI, Smartbird) and “undisclosed” appearing 2 times (Engine Biosciences is “undisclosed”; Trussed AI is “undisclosed”), while Pre-Seed heavily dominates the mid-window via the repeated $500K prints.

Frequently asked
What stands out on round size, and how extreme is the top disclosed check versus the rest?
Baseten’s $1.5B on 2026-06-22 is the only disclosed figure in the billions and it significantly exceeds the next-largest disclosed rounds in the list, such as Mirendil’s $200M (2026-06-24) and Assort Health’s $120M (2026-06-24). The lower end is tightly bounded: $500K is the smallest disclosed amount, showing up across multiple Pre-Seed financings dated 2026-06-16 (e.g., ProvenMetal on 2026-06-23 and Arden on 2026-06-16 at $500K).
Do the rounds cluster in time, or are they spread across a longer period?
They cluster heavily in mid-to-late June 2026. Many entries are dated 2026-06-16 with $500K Pre-Seed rounds (for example ProvenMetal’s $500K is on 2026-06-23, while Arden, Arzana, jo, and others are on 2026-06-16), and the bulk of other rounds land between 2026-06-17 and 2026-06-25, with the latest dated entry on 2026-06-30 (Derya at $1M).
Are there any notable outliers besides Baseten’s large check?
Yes. Engine Biosciences has an “undisclosed” amount on 2026-06-29, which prevents size benchmarking against other large rounds, while several mid-to-small disclosed rounds recur at fixed amounts (notably many Pre-Seed entries at $500K on 2026-06-16 such as Atrisa at $500K and Deep Interactions at $500K).
How does the stage mix look among these 50 entries, especially for Pre-Seed versus later stages?
Pre-Seed appears as the dominant labeled stage in the 2026-06-16 cluster, with many entries printing $500K (e.g., Arden, Arzana, Atrisa, BioStack, HEVN, Hyper, Savant, and others on 2026-06-16). Later stages include sizable financings such as Baseten’s Series F at $1.5B (2026-06-22), Assort Health’s Series C at $120M (2026-06-24), and Coval’s Series A at $28M (2026-06-24).
Are there “missing” amounts patterns like “Series Unknown” or “undisclosed,” and where do they occur?
“Series Unknown” shows up 3 times, including Engine Biosciences on 2026-06-29 (amount “undisclosed” in the table), Kled AI on 2026-06-25 ($3M), and Smartbird on 2026-06-17 ($100M). Separately, “undisclosed” amounts appear 2 times: Engine Biosciences on 2026-06-29 and Trussed AI on 2026-06-17, both preventing comparisons at the exact round size level.
