Nvidia-backed Lambda to Raise Up to $4B in Pre-IPO Round at $14.5B Valuation

The scale of Lambda's backlog growth, driven overwhelmingly by a single customer, is the real signal here: AI infrastructure demand is concentrating into a handful of hyperscale buyers, and Lambda's valuation now rests on that concentration. Coatue and Blackstone leading the pre-IPO round, ahead of a planned 2027 listing, suggests private capital is still willing to underwrite compute buildouts at late-stage prices. Whether that backlog converts to revenue on schedule — and whether Lambda can diversify beyond one anchor client before going public — is the open question.
