Shadeform, a GPU cloud marketplace, has launched Spot, a tool that lets GPU providers resell idle capacity at a discount. The San Francisco company announced it on October 20, 2026, during its Launch Week. Providers enrol a node with a single script. Shadeform can then resell the node whenever it would sit unused and hand it back when the provider needs it. Shadeform estimates the extra revenue cuts the total contract value of owned infrastructure by 29% on average. Buyers get dedicated GPU instances at a discount to on-demand rates, but instances can be pre-empted. Spot suits interruption-tolerant work such as checkpointed training, batch inference, and rendering. Users get advance notice before an instance is reclaimed. "Every hour a GPU sits idle is revenue left on the table," said Jeff Jewett, chief operating officer of Shadeform.

Shadeform has launched Flex VMs, a virtualisation layer that turns any bare-metal GPU cluster into single-tenant virtual machines and connects it to the San Francisco company's marketplace. Once approved, a node can be enrolled in about 30 minutes. Each node runs virtual machines with full GPU passthrough and no overcommit. Providers can pull nodes back at any time, or run their own workloads on them through Provider Priority. Owners register a machine with a short script, using only its IP address and an SSH key. Shadeform reviews each submission, replacing what used to require a full sales conversation. Providers can resell idle nodes on Spot with one click. Shadeform estimates this can cut total contract value by up to 29%. Its current Flex VMs have achieved more than 95% utilisation across Blackwell and Hopper series GPUs.
