Oxide Computer Company has raised $445 million in a Series D round led by Eclipse, the company announced on October 9, in one of the largest financings this year for a company that sells physical computers. The money is not for a new product launch. It is working capital — cash to buy components and expand manufacturing for a backlog of orders the company says it cannot build fast enough.
Returning investors US Innovative Technology Fund, Riot Ventures, and Jane Street took part, joined by new investors Atreides Management and AMD Ventures, the venture arm of chipmaker AMD, which joined as a strategic investor, according to the company’s release. An SEC Form D filing for the offering records $444,999,052 sold, with a first sale date of July 20, 2026. The round follows a $100 million Series B in July 2025 and a $200 million Series C in February 2026, bringing Oxide’s total funding to roughly $835 million.
A cloud you own, sold by the rack
Founded in 2019 in Emeryville, California, by Steve Tuck, Bryan Cantrill, and Jessie Frazelle, Oxide sells what it calls a Cloud Computer: a rack-scale system that combines purpose-built hardware with open-source software — compute, storage, networking, and a control plane designed together — that customers install in their own data centers and run with cloud-style automation. Its compute sleds are built on AMD EPYC processors, which makes AMD’s arrival on the shareholder register more than a financial bet. Oxide’s customers include organizations in financial services, government, national laboratories, and aerospace.
Profitable, and raising anyway
The detail Oxide led with is unusual for a growth-stage hardware company: it is already profitable. The founders said ordinary operations generated taxable income this spring — income from selling computers, after components, manufacturing, and salaries — a milestone they present as evidence of product-market fit.
So why raise $445 million? Because in hardware, growth consumes cash before it produces it. Components and manufacturing must be paid for well before a finished rack is delivered and an invoice is settled. Oxide says its existing cash, earlier financing, and debt facilities are enough to cover the current backlog. Without new capital, though, accepting much more demand would have meant being cautious to the point of turning customers away, in case a supply disruption or an economic shock hit mid-build. The Series D removes that constraint: the company can prepay for parts, expand production capacity, and keep taking orders.
The demand is real enough on the company’s telling. Chief executive Steve Tuck said in the release that manufacturing capacity has grown twentyfold over the past 12 months and demand still exceeds supply. Both the company and its investors tie that demand to agentic AI: as AI systems move from answering questions to executing work, enterprises need more CPU compute, memory, networking, and data infrastructure — and some want it on hardware they own. That is the same demand wave behind the federal AI compute commitments we covered in the Genesis Mission pledges, arriving here as purchase orders instead of press releases.
What Oxide did not say
The announcement discloses no valuation, no revenue figure, and no dollar value for the backlog it describes as large. Those gaps matter: the case for the round rests on demand the company has not quantified. What is verifiable is the sequence — three rounds in about fourteen months, each larger than the last, from a company that says it is profitable and still cannot manufacture fast enough. Whether owned, on-premises cloud becomes a durable third option between public cloud and traditional servers will be decided by deliveries, not announcements. Oxide now has the cash to make a lot of them.
