Nvidia, Blackstone back Firmus $2B raise, valuation tops $10.5B

Firmus's latest funding round reflects a critical shift in how major institutional investors view AI's infrastructure layer. While headlines focus on large language models and AI software, the physical backbone—data centers, power, cooling, and GPUs—requires even larger capital commitments and longer payoff horizons. Nvidia and Blackstone's continued backing (Coatue and Nvidia made follow-on investments, while Blackstone-managed funds and Jane Street joined) signals that despite warnings about unsustainable capital requirements in the AI boom, the most sophisticated investors believe the infrastructure itself will be foundational. Blackstone Senior Managing Director John Watson's statement that AI infrastructure is "among our highest conviction investment themes" underscores this conviction.

The deal also tightens the relationship between Nvidia and Firmus, moving beyond simple GPU sales toward a partnership model where customer commitments are jointly valued. A 360-megawatt facility supporting 170,000 Nvidia accelerators through 2027–2028, with expected revenues of $25 billion to $30 billion over six years, illustrates the scale of capital and the long-term revenue visibility investors are betting on. For Nvidia, this is a distribution channel and a hedge against a saturated domestic market; for Blackstone, it deepens exposure beyond the debt side into equity ownership and shared upside.
