- Lambda | Series E | $1.5 Billion | AI Infrastructure and Data Centers.
- Led by TWG Global, with participation from existing investor US Innovative Technology Fund.
- Funding will drive AI-specific data center construction, including a new Kansas City facility and large-scale cloud infrastructure partnerships.
Lambda, a pioneering AI infrastructure company, has announced the completion of a $1.5 billion Series E funding round, marking a significant step in its mission to scale AI-dedicated data centers. The financing was led by TWG Global, founded by billionaires Thomas Tull and Mark Walter, whose portfolio includes investments in Elon Musk's xAI and Palantir’s enterprise AI initiatives. Existing backer US Innovative Technology Fund also participated in the round. This capital injection positions Lambda as a formidable competitor to CoreWeave, further solidifying its role in the AI infrastructure ecosystem.
Founded in 2012, Lambda specializes in providing high-performance cloud platforms optimized for AI workloads. Its flagship offering, "Superclusters," provides unparalleled scalability with configurations supporting up to 165,000 GPUs in a single cluster. Lambda's flexibility extends to smaller-scale solutions, including single-instance rentals with up to eight GPUs and "one-click clusters" for short-term rentals that can mobilize up to 2,000 GPUs. This flexibility makes Lambda a key partner for enterprises requiring tailored AI infrastructure solutions.
The new funding will enable Lambda to accelerate its data center expansion, including the launch of a state-of-the-art facility in Kansas City slated for early next year. The initial capacity of this facility will be 24 megawatts, powered by 10,000 NVIDIA Blackwell Ultra GPUs. Notably, Lambda has also inked a multi-billion-dollar deal with Microsoft, under which Lambda will provide compute infrastructure featuring tens of thousands of NVIDIA GPUs. This partnership underscores Lambda's growing role as an essential AI compute provider for hyperscale cloud vendors. NVIDIA, a strategic investor in Lambda, further strengthens the company’s position in the AI ecosystem.
Prior to this round, Lambda raised $480 million in Series D funding in February 2025, which valued the company at approximately $2.5 billion. While specific valuation details from the Series E round have not been disclosed, market speculation suggests Lambda's valuation could now exceed $4 billion, with potential IPO ambitions on the horizon.
“ Lambda’s $1.5 billion funding round significantly elevates its competitive edge in the rapidly evolving AI infrastructure space. Its focus on AI-specific data centers, coupled with partnerships like the one with Microsoft, positions Lambda as a critical enabler of AI at scale. As the demand for high-performance compute surges, Lambda's tailored solutions offer a compelling alternative to mainstream cloud providers.” Saasverse Analyst comments
Saasverse Insights
Lambda’s trajectory highlights the intensifying race to dominate AI infrastructure, a sector poised to underpin the next decade of technological innovation. The company’s focus on AI-optimized environments like Superclusters reflects a broader shift toward specialized infrastructure as AI workloads become increasingly complex. Partnerships with hyperscale players such as Microsoft signify growing interdependence between specialized providers and general-purpose cloud giants. However, the sector remains competitive, with CoreWeave and others vying for dominance. Lambda’s success will depend not only on its ability to scale its infrastructure but also on maintaining its technological edge amidst rapid GPU advancements and increasing demand for flexible, high-performance compute solutions.
