Lambda, the rapidly growing U.S. AI data center provider, has raised $1.5 billion in new funding led by TWG Global, the $40 billion investment firm founded by Thomas Tull and Mark Walter. The raise follows Lambda’s recently announced multibillion-dollar agreement to supply Microsoft with large-scale AI infrastructure powered by tens of thousands of Nvidia GPUs, deepening its position as a key competitor to CoreWeave in the high-performance compute market. Nvidia is also an existing investor in the company.
TWG Global’s participation builds on its broader AI investment strategy, which includes a $15 billion AI-focused fund anchored by Mubadala Capital and previous partnerships involving xAI and Palantir. Lambda’s new capital dwarfs expectations that it would seek only several hundred million at a valuation above $4 billion, following its earlier $480 million Series D in February. The company did not comment on its current valuation.
Lambda plans to scale its national footprint of AI data centers and expand its “AI factory” infrastructure offerings for hyperscalers and enterprise customers.
