The Biggest Startup Capital Raises — Week 31, 2026 (SEC Form D)

51 operating-company raises totalling $1.3B surfaced in SEC Form D filings (July 30–31, 2026). The top 10, ranked — days before the press.

Every week, companies quietly disclose fresh capital raises in SEC Form D filings — often days before (and frequently without) any press coverage. We pull the filings straight from EDGAR, filter out pooled investment funds (the hedge/PE/VC noise that makes up most Form D volume), and rank what is left: the real operating-company startup-funding signal.

This window (July 30–31, 2026): 51 qualifying raises, $1.3B in disclosed capital.
