AI cloud startup Lambda has raised over $1.5 billion in a Series E round led by TWG Global. The funding will accelerate deployment of tens of thousands of high‑performance GPUs and construction of vertically integrated data centres, moving beyond leasing to ownership. Lambda, founded in 2012 and now backed by Nvidia and Microsoft contracts, aims to capitalize on the deepening AI model training demand and become a significant player in the neo‑cloud infrastructure race. Investors see infrastructure as the next frontier in AI stack expansion.
