AI-computing startup Lambda is raising $4 billion in a final funding round ahead of a planned initial public offering. The Wall Street Journal and TechCrunch both report that the company is backed by Nvidia and is preparing for an IPO in 2027.

Both outlets say the round is designed to bolster Lambda’s growth ahead of going public. TechCrunch adds specific terms, reporting the company seeks up to $4 billion at a $14.5 billion pre-money valuation. It also names the investors leading the round as Coatue and Blackstone, alongside other participants that are not detailed in the Wall Street Journal report. The Wall Street Journal emphasizes the timing—“final round” and a planned 2027 IPO—without providing the same valuation and lead-investor specifics.

Overall, the sources agree on the core facts: Lambda, an Nvidia-backed AI computing startup, is pursuing a $4 billion round and targets a 2027 IPO, while differing mainly in the level of deal detail provided.
