Aug 2025 in brief.
August 2025 was the only month in the archive without an acquisition. Eleven events, ≥$1.24B disclosed on all of them, 70% from Firefly Aerospace’s $868M IPO (Nasdaq: FLY), nine months after its Series D. Merlin’s SPAC combination with the Bleichroeder-led vehicle brought a committed PIPE of at least $125M for assured autonomous flight. Private rounds were all $65M or less: Vulcan Elements’ $65M Series A (Altimeter) for domestic rare-earth magnets, Stark’s $62M growth round (Sequoia) for Munich loitering munitions, Blue Water Autonomy’s $50M Series A (GV) for autonomous ships, SpinLaunch’s $30M growth financing, and five seeds and small rounds between $2.5M and $10.7M in manufacturing software (Dirac), orbital mobility (Orbital Operations), industrial workforce (Laborup) and cargo drones (Grid Aero). Defense Manufacturing tied Space and Autonomy for the most events, with three each.
Two exits from the private tape into public markets in one month, with no M&A alongside, says something about where late-stage defense capital was being priced in mid-2025. The more durable signal is rare earths: Vulcan Elements’ round follows the Defense Department’s MP Materials stake by a month, and the magnet supply chain is now an investable category rather than a policy talking point.
Activity vs each domain’s own baseline.
Each cell is the number of publicly announced deals in that domain and month. Color compares the month with that domain’s own average over the months shown — not a scale shared across domains — so a dark cell in a small domain means “busy for that domain”, not “large in dollars”. Domains with fewer than 12 events in the window are shown in gray without color. Absolute totals across all 24 months are on the archive home.

No domain moved outside its normal range.
No domain yet has enough history for a percentage callout. We flag a domain only when its last three months differ from the prior three by 30% or more and it has at least 36 events in the trailing 12 months. Smaller samples stay as raw counts on the heat map; we never quote month-over-month percentages.

Method & coverage
Public sources only · Issue window = first public announcement in Aug 2025 · 11 announced or closed events (F 9 · M 0 · P 2) · Disclosed floor ≥$1.24B across 11 of 11 (0% undisclosed) · Closings of deals first announced in an earlier month are not counted again here · Capital-supply items are sidebar-only and excluded from domain statistics · Heat-map colors use each domain’s own trailing-12-month baseline.
Event codes & terms
Disclosed floor — the sum of publicly disclosed amounts only. Undisclosed deals add zero, so read every total as “at least”.
Announcement month — events are dated to their first public announcement. A close in a later month does not move the event.
Mission domain — the market the capital is buying: the investor’s thesis first, the product second. One primary domain per event.
Heat-map baseline — color compares a month’s count with the same domain’s average over the trailing 12 months shown. Grey means fewer than 12 events in the window, too few to color.
