QumulusAI signed a three-year, $99.6 million subscription for 128 bare-metal clustered NVIDIA B300 GPU nodes, requiring $16.9 million upfront.

QumulusAI entered the customer contract on May 11, 2026. The customer subscribed to 128 bare-metal clustered NVIDIA B300 GPU nodes for a three-year term, with aggregate contracted fees of approximately $99.6 million.

The customer is required to make an upfront payment of approximately $16.9 million. The remaining fees are payable over the term of the agreement, so the full $99.6 million was not described as an immediate cash receipt or already recognized revenue.

The contracted unit is a GPU node, not an individual GPU. The filing does not specify how many NVIDIA B300 accelerators are installed in each node, and the 128-node count therefore should not be presented as 128 GPUs.

The agreement was disclosed in QumulusAI’s Form 10-Q as an executed customer contract. The filing also identifies broader risks involving equipment supply, power availability, facility interruptions, customer concentration and dependence on a single GPU-as-a-Service channel partner.
