Across the 50 most recent “Venture - Series Unknown” rounds shown (dated 2025-11-18 through 2025-11-30), Kalshi’s $1.0B round on 2025-11-22 dwarfs the rest of the disclosed amounts: the next-largest disclosed rounds are $600M (Physical Intelligence, 2025-11-21), $331M (Apptronik, 2025-11-28), and $300M (Ramp, 2025-11-23). At the smaller end, multiple companies cluster around the $1M–$5M band, including AI Metrics ($950K on 2025-11-29), Lonestar ($400K on 2025-11-26), Paystand ($290K on 2025-11-27), and the smallest disclosed amount: Lonestar at $400K.
The list also concentrates geographically and by sector. Los Angeles, New York, and San Francisco each appear multiple times (e.g., Suma Wealth in Los Angeles; Ramp and Obex in New York; Verisoul, Solana? is not in SF; SpecterOps and Physical Intelligence and others are in San Francisco), while AI is unusually frequent across entries such as Verisoul (2025-11-30, $7M), Apptronik (2025-11-28, $331M), Kalshi (2025-11-22, $1.0B), and Physical Intelligence (2025-11-21, $600M). Finally, amounts are disclosed in most rows but not all: 4 entries are “undisclosed” (Alchemy, Cosmos Innovation, Permian Labs, and RaySecur), spanning 2025-11-20 to 2025-11-24.

Frequently asked
What does the largest disclosed “Venture - Series Unknown” round look like versus the rest of this list?
Kalshi’s $1.0B round (2025-11-22) is an extreme outlier among disclosed amounts, followed by $600M (Physical Intelligence, 2025-11-21), $331M (Apptronik, 2025-11-28), and $300M (Ramp, 2025-11-23). Everything else shown sits well below those figures, even with multiple mid-$100M rounds such as Solve Therapeutics at $120M (2025-11-21).
Which disclosed rounds are at the low end, and how low do the smallest amounts go?
The smallest disclosed amount in the rows is Lonestar at $400K on 2025-11-26. Other sub-$1M disclosed rounds include Paystand at $290K (2025-11-27), AI Metrics at $950K (2025-11-29), and both BC3 Technologies ($1M, 2025-11-29) and QuantHUB ($1M, 2025-11-20) sitting right on the $1M threshold.
Is there a tight temporal cluster in the most recent months covered here?
Yes. All 50 entries fall within a narrow window from 2025-11-18 (Cybrary, $5M) to 2025-11-30 (Suma Wealth $6M; Verisoul $7M). The top-of-list dates (2025-11-29 and 2025-11-28) include multiple disclosed rounds such as International Battery Company ($25M, 2025-11-29) and Apptronik ($331M, 2025-11-28).
Do any locations appear repeatedly across these “Series Unknown” rounds?
Several cities recur, indicating localized concentration. New York appears multiple times (Ramp $300M on 2025-11-23; Obex $37M on 2025-11-22; plus Permian Labs and Sortera Alloys entries are in other cities, with other New York entries like Amogy in Brooklyn), while San Francisco shows up with multiple large rounds such as Physical Intelligence ($600M, 2025-11-21) and SpecterOps ($30M, 2025-11-25). Los Angeles also appears via Suma Wealth at $6M on 2025-11-30.
How does the sector mix tilt, and is AI over-represented compared with single-sector one-offs?
AI shows up repeatedly across materially sized rounds, including Verisoul ($7M, 2025-11-30), Apptronik ($331M, 2025-11-28), Kalshi ($1.0B, 2025-11-22), and Physical Intelligence ($600M, 2025-11-21). This is complemented by other AI-labeled entries like vijil ($17M, 2025-11-27) and Sunday (35M, 2025-11-19), suggesting AI is not just a one-off label in this slice.
Are there notable “undisclosed” amounts that could skew comparisons of deal size?
Four entries are marked “undisclosed”: Alchemy (2025-11-24), Cosmos Innovation (2025-11-24), Permian Labs (2025-11-23), and RaySecur (2025-11-23). Because the largest disclosed rounds are extremely high (Kalshi $1.0B on 2025-11-22; Physical Intelligence $600M on 2025-11-21), these undisclosed rows could affect how many additional mid-to-high rounds exist, but they do not change the disclosed outlier ranking driven by Kalshi.
