Lambda has raised over $2.36 billion across multiple rounds, culminating in a $1.5 billion Series E in November 2025 led by TWG Global and the US Innovative Technology Fund. Prior rounds include a $480M Series D, $320M Series C, $44M Series B, $15M Series A, and approximately $4M in pre-seed funding from Gradient Ventures, the 1517 Fund, and Bloomberg Beta. This capital accelerates Lambda’s expansion of GPU cloud clusters, on-prem AI compute appliances, and large-scale AI training infrastructure.
