August's Megarounds Went to Missiles and Inference

In a single mid-August week, six US startups raised $2.63 billion between them, and the two largest -- a hypersonic missile maker and an inference chip company -- accounted for $1.5 billion of it.

The VC Read · Trace's Take

Trace Cohen

Six rounds, $2.63 billion, and 57% of it went to two companies building physical things -- missiles and silicon. Software rounds are still happening; they are just no longer where the dollars concentrate. For seed GPs the practical consequence is that your best companies now need a defensible hardware or data story to attract a $500 million-plus Series C in this market. Rillet raising three times in twelve months at $1 billion is the exception that proves it: AI-native accounting works because the incumbent is NetSuite, not because software is back in favor.

Analysis

Six US companies raised $2.63 billion in equity across one week in mid-August, and the distribution tells you where the dollar-weighted center of venture now sits. The Crunchbase weekly tally put defense and AI infrastructure at the top of the list.

  • Castelion -- $800 million equity plus $250 million debt at $13 billion (JPMorgan Chase, Andreessen Horowitz, Carlyle): hypersonic strike missiles, Torrance, California. Pulse covered the $13 billion mark. Competitors: Anduril, Lockheed Martin's hypersonics program.
  • Etched -- $700 million at $21 billion (Jane Street): transformer-specific inference silicon, San Jose, founded 2022. Pulse covered the Jane Street round. Competitors: Groq, Cerebras, Nvidia.
  • Higgsfield -- $400 million at $5.4 billion (DST Global): AI video tools, San Francisco, with more than 18 investors in the Series B.
  • Groq -- $350 million at $3.5 billion (Disruptive, Nvidia): 13 global data centers, San Francisco. Pulse covered the neocloud pivot.
  • Wispr Flow -- $280 million at $2 billion (Menlo Ventures): voice-to-text.
  • Rillet -- $100 million at $1 billion (Iconiq Capital): AI accounting software, San Francisco, its third financing inside twelve months.

Pulse covered the $13 billion mark.

Two numbers stand out against each other. Etched raised $700 million at $21 billion -- a 30x forward multiple on a company with no meaningful shipped revenue -- while Groq raised half as much at one-sixth the valuation despite operating 13 data centers. The market is paying for architectural bets, not for deployed capacity. And Castelion's $250 million debt tranche alongside $800 million of equity is the detail growth investors should sit with: defense hardware has become creditworthy enough that a bank will lend against it pre-revenue at scale.

Update (September 3, 2026): Pulse has follow-up coverage — Global VC Funding Jumped 122% in August From a Year Ago.
