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. Coatue Management and Blackstone are leading the round.
A letter to investors reviewed by The Wall Street Journal shows Lambda’s backlog grew from $15 billion in June to $50 billion in September. This increase is largely driven by a $35 billion commitment from Anthropic, which signed a deal with Lambda in late August. Consequently, Lambda’s valuation could be heavily reliant on Anthropic’s ability to maintain its payments.
Investors are still willing to bet on companies that provide reliable GPU capacity, especially those with large contracts with major AI labs. For neoclouds like Lambda, demand isn’t so much the problem as is the cost of meeting it. Lambda recently raised an additional $1 billion to support its expansion efforts, which are largely funded by debt. However, lenders are becoming choosier about whom they offer cash to and under what circumstances.
Lambda’s decision to raise more capital now not only sets the tone for its IPO pricing but also gives it access to more capital before the scrutiny of public markets arrives. As Lambda prepares for its IPO, it will join other Nvidia-backed neoclouds, like CoreWeave and Nebius, which also depend on their stock performance to fund data center buildouts.
Although Lambda’s IPO was reportedly meant to debut this year, it has been postponed amid market uncertainty. This changing landscape of AI infrastructure funding makes this upcoming round particularly significant, reflecting institutional validation of the neocloud sector.
