AI Capital Concentration: $84B in Foundation Model Mega-Rounds

AI Capital Concentration: $84B in Foundation Model Mega-Rounds

The 2025 funding data reveals structural confirmation of winner-take-most dynamics. Foundation model companies captured 40% of all global AI funding ($80 billion), up from 27% in 2024.

The Numbers That Matter

  • $84B in foundation model mega-rounds in 2025
  • $40B SoftBank commitment to OpenAI—largest single AI investment in history
  • $13B Anthropic raise at $183B valuation; revenue from $1B to $5B in 8 months

The Capital Stack Inversion

Source Amount Rounds
Private Equity $63B 300
Venture Capital $38B 1,600

PE now funds the largest AI bets while VC handles volume. This mirrors the M&A pattern where 68 megadeals (≥$10B) drove market transformation while total deal count fell to 2016 lows.

Structural Implication

The capital stack has inverted. Like megadeal M&A, transformation is now driven by a small number of oversized bets, not startup volume. The top 2 foundation models (OpenAI, Anthropic) captured 14% of all global venture investment in 2025.
