The disclosed rounds in Stamford skew heavily toward a single outlier: Six One Commodities raised $800M on 2026-05-08, which dwarfs the next-largest disclosed amount ($600M by Digital Currency Group on 2021-11-18). The rest of the disclosed cheques cluster well below this top tier, with multiple entries in the tens of millions (e.g., Aircastle at $375M on 2026-05-21; Treeline Biosciences at $261M on 2022-10-11) and several smaller rounds (such as $100K for Eleanor on 2021-10-01).
Date-wise, activity runs from 2021-10-01 to 2026-07-16, with the most recent disclosed round also coming from an atypically large scale event (Orange Juice at $40M on 2026-07-16), while the largest disclosed amounts are concentrated in earlier spikes (notably 2022-09 and 2022-01 via SpringWorks Therapeutics at $225M on 2022-09-07 and Sema4 at $200M on 2022-01-18). Stamford appears in all 50 rows; there is one non-Stamford geography in the table (Eleanor is listed in Stamford, Lincolnshire, United Kingdom).

Frequently asked
How does the largest disclosed Stamford round compare to the rest of the disclosed amounts?
Six One Commodities’ $800M (2026-05-08) is the only disclosed entry above $600M, and it dwarfs every other disclosed round that follows. The next-largest disclosed amount is Digital Currency Group at $600M (2021-11-18), with the next ranks stepping down to $493M (Hildene, 2024-11-13) and $375M (Aircastle, 2026-05-21).
Are there notable clusters in time among the largest disclosed rounds?
The upper tail shows cluster-like timing around 2022 and mid-2026: SpringWorks Therapeutics raised $225M on 2022-09-07 and Sema4 raised $200M on 2022-01-18, while Aircastle’s $375M (2026-05-21) and Six One Commodities’ $800M (2026-05-08) both land in May 2026. Between 2024-11-13 ($493M, Hildene) and 2026-05 (Aircastle/Six One Commodities), there’s a pronounced jump in disclosed scale versus the many single-digit millions elsewhere.
Which sectors appear most consistently across these 50 rows, and does the size distribution match?
Artificial Intelligence (AI) shows up repeatedly across multiple entries, including Noteworthy AI ($6M on 2023-10-20), Upswing Health ($5M on 2022-05-02), and Copyleaks Inc. ($6M on 2022-05-24), alongside Orange Juice being tied to Bitcoin (2026-07-16, $40M). Even with AI appearing multiple times, the biggest disclosed cheques in the list come from non-AI categories: Six One Commodities ($800M, Energy), Digital Currency Group ($600M, Financial Services), and Treeline Biosciences ($261M, Biotechnology).
How prevalent is ‘Series Unknown’ in this Stamford dataset, and what does it imply when paired with disclosed sizes?
‘Series Unknown’ appears 5 out of the top 8 disclosed ranks? It does not apply cleanly because stage labels differ across the ranked top-eight amounts, but overall the listing has 9 undisclosed amounts out of 50 and multiple ‘Series Unknown’ classifications (e.g., Sands Point Risk on 2026-06-11 is undisclosed; Altus Power on 2026-06-02 is undisclosed). Practically, the largest disclosed events still have clear disclosed dollar figures (e.g., Aircastle $375M on 2026-05-21; Treeline Biosciences $261M on 2022-10-11), but a meaningful share of entries provide neither amount nor stage.
What does the most recent 90-day window look like, based on the listed dates and disclosed amounts?
Within the latest entries, disclosed amounts include Orange Juice at $40M (2026-07-16), Luxe Supply Company at $6M (2026-07-13), and OncoSynergy at $7M (2026-05-26), with larger activity in May 2026 such as Six One Commodities at $800M (2026-05-08) and Aircastle at $375M (2026-05-21). Compared with the earlier disclosed peak years (e.g., Digital Currency Group $600M on 2021-11-18; Sema4 $200M on 2022-01-18), the newest window combines mid-single-digit rounds with one extreme outlier.
Which entry is the smallest disclosed round, and how stark is the gap versus the top disclosed amount?
The smallest disclosed amount is $100K for Eleanor on 2021-10-01. The top disclosed amount is $800M for Six One Commodities (2026-05-08), creating a gap of several orders of magnitude, far larger than the differences seen among mid-to-high disclosed rounds like Hildene ($493M, 2024-11-13) and Aircastle ($375M, 2026-05-21).
