Among the 12 most recent disclosed Series F AI rounds, the largest disclosed amount is Baseten’s $1.5B (2026-06-22), which dwarfs the next-largest disclosed round at $1.0B (SambaNova, 2026-07-08). The top of the range is still relatively concentrated: five companies list disclosed rounds at or above $220M (Dataminr $475M on 2021-03-23; Cerebras Systems $250M on 2021-11-10; Highspot $248M on 2022-01-13; Clari $225M on 2022-01-19; WorkFusion $220M on 2021-03-09).
Geographically, New York and Sunnyvale both appear three times each (with San Francisco appearing twice), indicating a multi-hub pattern rather than a single city concentration. Temporally, the newest two rounds are tightly clustered in June–July 2026 (Baseten 2026-06-22 and SambaNova 2026-07-08), while the list stretches back to 2021-03-09 (WorkFusion), creating clear “recent edge” coverage within a 2021-03-09 to 2026-07-08 window.

Frequently asked
What does the largest disclosed Series F AI round look like versus the rest of the list?
Baseten’s $1.5B (2026-06-22) is the top disclosed amount and sits far above the rest of the distribution; the next-largest disclosed is SambaNova at $1.0B (2026-07-08). Supabase is the only other round in the $500M tier at $500M (2026-06-04), followed by Dataminr at $475M (2021-03-23).
Are the newest rounds clustered in time?
Yes. Two of the twelve entries fall within a span of weeks in 2026: Baseten closed $1.5B on 2026-06-22 and SambaNova closed $1.0B on 2026-07-08. In addition, the list includes another nearby June 2026 close at Supabase’s $500M (2026-06-04).
Do certain cities show up more frequently than others?
New York and Sunnyvale each appear three times across the 12 rows (while San Francisco appears twice), suggesting repeated hub concentration. Examples include New York entries like Augury ($75M, 2025-02-19), Dataminr ($475M, 2021-03-23), and WorkFusion ($220M, 2021-03-09), plus Sunnyvale entries like Clari ($225M, 2022-01-19), Highspot ($248M, 2022-01-13), and Cerebras Systems ($250M, 2021-11-10).
Are there meaningful outliers to flag for deeper diligence?
Baseten’s $1.5B (2026-06-22) is a size outlier relative to most of the remainder, where several disclosed rounds sit below $500M (e.g., Augury $75M on 2025-02-19; Neo4j $66M on 2021-11-09). At the lower end, Neo4j’s $66M (2021-11-09) is the smallest disclosed amount in the set.
How does the disclosed amount stack by time, from earliest to most recent?
The earliest disclosed rounds shown are from March 2021 onward (e.g., WorkFusion $220M on 2021-03-09; Dataminr $475M on 2021-03-23; Cerebras Systems $250M on 2021-11-10). The most recent edge shifts up in absolute disclosed value, with the top two amounts both appearing in June–July 2026 (Baseten $1.5B on 2026-06-22; SambaNova $1.0B on 2026-07-08).
