Lambda Inc., an Nvidia-backed AI cloud-computing provider, is in talks to raise as much as $3 billion in a funding round that would position the company for a public offering in the second half of 2026, according to people familiar with the matter.
The round size would value Lambda at a level that shows investor appetite for infrastructure built around generative AI workloads. Nvidia has been among Lambda's backers, giving the chipmaker exposure to demand from companies building AI applications without developing their own data centers.
Lambda operates cloud compute resources leased primarily to researchers, startups and enterprises training large language models and other AI systems. The company competes with established cloud providers including Amazon Web Services, Google Cloud and Microsoft Azure, as well as newer entrants focused on GPU availability. Lambda's infrastructure runs on Nvidia chips, which remain the bottleneck for most AI development work.
The timing of a H2 2026 IPO would place Lambda among a wave of infrastructure companies seeking public capital as generative AI adoption accelerates. The company has not disclosed financials, but the $3 billion fundraise indicates it has achieved substantial revenue or demonstrated a path to scale that justifies the valuation among growth investors.
Nvidia's backing carries weight with institutional allocators evaluating AI infrastructure plays. The chipmaker has become central to venture and growth portfolios seeking exposure to the AI supply chain beyond semiconductor manufacturing itself. Nvidia has also invested in other cloud and software companies building on its GPU ecosystem.
A public listing would give Lambda access to capital markets funding for expansion at a moment when GPU procurement and data center buildout remain expensive. The company would compete for institutional investor capital against both traditional cloud giants and smaller infrastructure specialists. The fundraising talks do not guarantee a successful round or an IPO at the stated timeline.
The gap between a $3 billion pre-IPO round and Lambda's eventual public market valuation will determine whether the round priced fairly or at a discount. Similar infrastructure companies have seen their public valuations reset sharply in the months following IPO as revenue growth diverges from pre-market expectations. If Lambda completes the $3 billion round and files an S-1 prospectus by Q3 2026, that filing will show the company's actual revenue run rate and customer composition for the first time.
