Disclosed funding amounts in this United States energy set are highly skewed: the largest disclosed round is Base Power’s $1.0B on 2025-10-07, which dwarfs the rest of the disclosed figures. Several other entries cluster far lower, including HighPeak Energy’s $1.2B on 2025-08-01 and XENERGY’s $700M on 2025-11-27 at the top end, while the low end is led by EnergyAid at just $250K on 2025-08-26 (with multiple “undisclosed” rounds below that not counted here).
Timing and geography also concentrate. The 50 most recent rows span 2025-07-22 to 2025-11-27, and there’s a clear mid/late-September cluster, with multiple disclosed rounds between 2025-09-08 and 2025-09-18 (e.g., XENDEE Corporation undisclosed on 2025-09-08; Valar Atomics $130M on 2025-11-11 notwithstanding). San Francisco appears repeatedly (Gridware 2025-11-23 $55M; Aether Fuels 2025-08-11 undisclosed; and LanzaTech is in Illinois, while Enovix is Fremont), and “Series Unknown” is common, appearing on 21 of the 50 rows—often paired with large mid-size checks such as EVgo $225M on 2025-07-23 and Nanoramic Laboratories $54M on 2025-11-18.

Frequently asked
What stands out in round sizes, and how extreme are the outliers?
The biggest disclosed amount is HighPeak Energy’s $1.2B on 2025-08-01, which is dramatically above the remaining disclosed rounds. At the low end, EnergyAid’s disclosed $250K on 2025-08-26 sits far below the next small disclosed checks like Active Surfaces at $350K (2025-08-15).
Are there any clear date clusters in the most recent entries?
Yes: beyond the overall window of 2025-07-22 to 2025-11-27, mid/late September shows repeated activity, including Gridware’s $55M (2025-11-23 is later) but specifically 2025-09-16/09-18 entries such as EnTouch Controls (undisclosed, 2025-09-16) and Producers Midstream’s $500M (2025-10-12) alongside Fourth Power’s $20M (2025-09-18).
Which stage labels dominate, and how often is the stage not disclosed?
“Series Unknown” appears on 21 of 50 rows (e.g., EVgo $225M on 2025-07-23; Sora Fuel undisclosed on 2025-08-11; and Virtual Peaker undisclosed on 2025-08-06). Separately, “undisclosed” amounts appear on multiple rows as well (e.g., Pike on 2025-11-22 and Pike’s amount is not shown), meaning both stage and size disclosure frequently drop out together.
Do any cities repeat often enough to suggest a sourcing or market cluster?
San Francisco shows up multiple times in this list: Gridware is in San Francisco (2025-11-23, $55M), while Aether Fuels is also San Francisco (2025-08-11, amount undisclosed) and Enovix is in Fremont (not San Francisco) on 2025-08-27 at $110M, indicating repeated Bay Area presence rather than a single one-off.
Which energy funding checkpoints would be most useful for outreach based on disclosed amounts?
For outbound targeting anchored on disclosed size, the top disclosed rounds are concentrated in a small set of entries: HighPeak Energy $1.2B (2025-08-01), Base Power $1.0B (2025-10-07), and XENERGY $700M (2025-11-27). Mid-tier disclosed checks recur as well, including EVgo $225M (2025-07-23), Nautilus Solar Energy $275M (2025-07-23), and Intuitive Machines $300M (2025-08-13).
