The IPO-bound GPU-cloud start-up adds one of the largest US quantitative trading firms to a customer list that already includes Microsoft and NVIDIA itself.
Lambda has signed a cloud-infrastructure deal with Hudson River Trading, one of the largest US quantitative trading firms, to supply HRT with access to NVIDIA chips, Reuters reported on Wednesday.
The agreement extends Lambda’s customer list across the high-frequency-trading category at a moment the GPU-cloud start-up is preparing for an IPO in the first half of 2026.
The deal puts HRT on a Lambda customer roster that already includes Microsoft and NVIDIA itself. Lambda announced its multibillion-dollar Microsoft agreement in November 2025, covering tens of thousands of NVIDIA GPUs, including the GB300 NVL72 systems; NVIDIA separately signed a $1.5bn four-year deal to lease back roughly 18,000 of its own GPUs from Lambda, an arrangement that made NVIDIA the start-up’s largest single customer.
Layering an HRT contract on top of that base extends Lambda’s exposure into the latency-sensitive segment of the GPU market, where customer pricing typically clears at a premium to model-training workloads.
