NVIDIA-backed AI computing startup Lambda is seeking to raise up to $4 billion at a pre-money valuation of $14.5 billion ahead of a planned initial public offering (IPO) in 2027. This funding round is led by Coatue Management and Blackstone. According to The Wall Street Journal, Lambda's backlog grew from $15 billion in June to $50 billion in September, with most of the increase coming from a $35 billion commitment signed with Anthropic in late August.
