Oxide Computer has raised $445M in Series D funding, led by returning backer Eclipse Capital. AMD Ventures, Riot Ventures, Jane Street, Atreides Management and USIT joined the round.
The pitch is unglamorous and, judging by the numbers, effective. Oxide sells a single pre-integrated rack that bundles compute, storage and networking, rather than asking enterprises to assemble a data center from parts. Every rack holds 24 modules the company calls sleds, each carrying an AMD processor with up to 144 cores, about 1.64 terabytes of memory and as much as 300 terabytes of flash.
The engineering is in the plumbing
A custom chip called the Oxide Server Processor watches over each sled, managing temperatures, power flow and firmware updates. Redundant switches run a bespoke routing protocol that keeps a live map of the rack’s internal network, steering traffic around a failing link before users notice.
Storage is protected by writing three copies of each record across separate flash modules, with a checksum sweep hunting for errors in the background. Power arrives through two shelves of rectifiers, and customers can carve the hardware into isolated virtual networks separated by a built-in firewall.
Supply is the constraint
Chief executive Steve Tuck says the company has already scaled manufacturing capacity twentyfold in a year and still cannot keep up. “Demand still exceeds supply,” he said, framing the raise as a bet on materials and factory lines rather than new features.
That framing matters. Oxide is not selling a story about AI software – it is selling physical infrastructure to companies that have decided public cloud is too expensive or too opaque. As long as that sentiment holds, the bottleneck is the building, not the buyer.
