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

AI infrastructure startup Lambda is raising $4 billion at a $14.5 billion valuation as it prepares for a potential 2027 IPO. The company's growth is heavily supported by a massive $35 billion contract with AI lab Anthropic.
Why it matters
This funding round underscores the massive capital requirements and high-stakes partnerships driving the current AI infrastructure boom.
Cloud provider Lambda is raising up to $4 billion at a $14.5 billion pre-money valuation, marking what could be its last private round before a planned 2027 IPO, according to The Wall Street Journal. Coatue Management and Blackstone are leading the round.
A letter to investors reviewed by the Journal shows Lambda’s backlog grew from $15 billion in June to $50 billion in September. While that might look like a hearty increase in demand, much of that increase appears to be driven by a $35 billion commitment from one company: Anthropic, which signed a deal with Lambda in late August.
