Disclosed round sizes in this “Series Unknown” energy slice are heavily right-skewed: HighPeak Energy’s $1.2B round on 2025-08-01 dwarfs the rest of the disclosed amounts, with the next-largest disclosed entries including Motor Fuel Group at $664M (2025-08-04) and TeraWulf at $850M (2025-08-18). The smallest disclosed amount is $250K (EnergyAid on 2025-08-26), while a large fraction of the rows remain undisclosed (undisclosed appears in 15 of 50 entries), limiting direct size comparisons for many deals.
Temporal clustering is tighter at the top of the list: 2025-08-04 through 2025-08-27 contains the most recent activity, and multiple cities repeat within the same time window (notably Vancouver, British Columbia with Moment Energy $4M on 2025-08-25, General Fusion $22M on 2025-08-21, and EverGen Infrastructure $4M on 2025-08-07). Geographically the dataset spans North America, Europe, Asia, and Africa, but the United States appears frequently (e.g., Enovix $110M on 2025-08-27; Intuitive Machines $300M on 2025-08-13; Howard Energy Partners $750M on 2025-08-05).

Frequently asked
What’s the largest disclosed round here, and how much larger is it than the rest?
HighPeak Energy’s $1.2B disclosed round on 2025-08-01 is an outlier in this list; it dwarfs other disclosed amounts such as TeraWulf at $850M (2025-08-18) and Motor Fuel Group at $664M (2025-08-04).
How often are amounts undisclosed in this Series Unknown set, and does that affect comparability?
15 of the 50 rows show “undisclosed” amounts (e.g., Nanoramic Laboratories on 2025-08-27; Streamline Innovations on 2025-08-19; Energy Dome on 2025-07-25). That means only 35 entries contribute to disclosed-size comparisons like the $110M Enovix round (2025-08-27) versus $250K EnergyAid (2025-08-26).
Is there a tight date window where many rounds land?
Yes. Most entries concentrate in late August 2025—e.g., 2025-08-27 (Enovix $110M; Nanoramic Laboratories undisclosed), 2025-08-26 (EnergyAid $250K; Fusion Fuel Cycles $20M), and 2025-08-25 (ABO Energy $281M; Moment Energy $4M). The list spans from 2025-07-24 (Energy Vault $18M) to 2025-08-27 as the most recent date in the rows shown.
Are any cities or metro areas over-represented?
Vancouver, British Columbia repeats within this set: Moment Energy (Coquitlam, British Columbia) is separate from the “Vancouver” city label, but General Fusion in Richmond (2025-08-21) and multiple British Columbia entries cluster broadly around the same geography/time window; EverGen Infrastructure is explicitly “Vancouver, British Columbia” on 2025-08-07 for $4M. The US also appears repeatedly across different cities, such as Fremont (Enovix $110M on 2025-08-27) and San Francisco (Aether Fuels undisclosed on 2025-08-11; Lumen Energy $2M on 2025-08-02).
Which disclosed deals sit at the low end, and do they cluster around specific dates?
The smallest disclosed amount is $250K for EnergyAid on 2025-08-26, which is paired with other low-to-mid disclosed rounds in the same week (e.g., Lumen Energy $2M on 2025-08-02; Wassha $2M on 2025-08-15). While multiple sub-$5M rounds appear (e.g., Seabound $2M on 2025-08-20; Vast $2M on 2025-08-11), the list’s most recent cluster is dominated by much larger disclosed outliers like HighPeak Energy $1.2B on 2025-08-01.
