AI computing startup Lambda to raise $4B ahead of planned IPO

What happened: Cloud provider Lambda is raising up to $4 billion at a $14.5 billion pre-money valuation, possibly its last private round before a planned 2027 IPO. Coatue Management and Blackstone are leading the round. Key numbers: Up to $4B raise. $14.5B pre-money valuation. Backlog grew from $15B in June to $50B in September. $35B commitment from Anthropic. Why it matters: Much of the backlog growth appears tied to Anthropic's ability to keep paying, so the valuation may lean on that contract. The raise sets the tone for IPO pricing and adds capital before public market scrutiny.
