Sep 2025 in brief.
The lightest count since January — eight events, all financings or public-market steps — with a ≥$704M floor. Apex Space raised $200M again (Series D, Interlagos), five months after a $200M Series C, on national-security constellation demand. Auterion’s $130M Series B (Bessemer) funds autonomy software for drone swarms across air, land and sea. Infleqtion announced its SPAC combination with Churchill Capital Corp X (PIPE of $125M) three months after its Series C. The mid-tier was munitions and sensing: Shift5’s $75M Series C (Hedosophia) for operational-technology security on defense fleets, Vector’s $61M Series A (Pelion) for military-spec FPV strike drones, Firehawk’s $60M oversubscribed Series C for 3D-printed energetics and solid rocket motors, and ReOrbit’s $53M Series A for sovereign satellites (Helsinki). Razor’s Edge and Enlightenment Capital made an undisclosed strategic investment in Expedition Technology (SIGINT and GEOINT AI).
September’s pattern is repeat capital: Apex and Infleqtion both took a second capital step within five months of the first. Vector and Firehawk are first-time tape entrants in munitions manufacturing — the low-cost strike and energetics theme that peaks in August 2026. When the count is this low, the second-order read matters most: the companies raising here are the ones whose competitors get diligenced next.
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 Sep 2025 · 8 announced or closed events (F 7 · M 0 · P 1) · Disclosed floor ≥$704M across 7 of 8 (12% 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.
