The Biggest Startup Capital Raises - Week 36, 2026 (SEC Form D)

59 operating-company raises totalling $999.6M surfaced in SEC Form D filings (September 3-4, 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 (September 3-4, 2026): 59 qualifying raises, $999.6M in disclosed capital.
