Oxide bets on the cloud you own; $200M Series C, then a $445M Form D

Designs and manufactures the Oxide Cloud Computer, a rack-scale system combining compute, storage, networking and open-source software that delivers a public-cloud-style, API-driven experience inside an on-premises data center.

That enterprises with sovereignty, latency or cost constraints want hyperscale-style cloud APIs on hardware they own — one integrated rack, sold rather than rented.

$200M Series C in February 2026 led by Thomas Tull's US Innovative Technology Fund, with Eclipse, Riot Ventures and Jane Street participating; a subsequent $445M Form D offering — $444,999,052 sold to 15 investors, first sale 2026-07-20 — filed with the SEC on 2026-08-04.

Founded by Steve Tuck and Bryan Cantrill, veterans of Sun Microsystems and the Joyent cloud startup, who argued the on-prem market had been abandoned to an eight-vendor DIY stack or renting from hyperscalers. They set out to build the entire cloud computer, hardware and software, as one product.

After years of engineering the Hubris OS and open firmware, Oxide brought the Oxide Cloud Computer to market and in June 2026 announced it would leverage colocation at CoreSite's SV2 Silicon Valley data center. In February 2026 it closed a $200M Series C led by Thomas Tull's USIT; in July 2026 it sold $445M in a new round disclosed in an SEC Form D — more than double the Series C — signed by president Steve Tuck on 2026-08-04.

Still scaling: the $445M raise gives years of runway to expand manufacturing and customer support for enterprises planning projects measured in decades; publicly discussed customers include Jane Street and a national lab, and Oxide itself had not confirmed the shape of the round beyond the Form D as of September 2026.

Public-cloud API convenience plus on-prem ownership resolves the sovereignty, cost and lock-in objections that disqualify hyperscalers for sensitive buyers.

A single integrated rack kills the eight-vendor finger-pointing and licensing overhead of traditional on-prem stacks.

Customers like Jane Street and national labs buy on decade horizons, so demonstrated long-term funding is a core purchasing criterion.

A $445M round more than doubling the Series C signals the category is real — and raises the bar for any would-be clone.

Capital intensity is a moat when customers plan decade-long infrastructure bets: a bigger balance sheet is itself the sales pitch, because buyers must believe the vendor will outlive the contract.

As of 2026-09-02, the SEC Form D shows Oxide Computer Co raised $444,999,052 from 15 investors in an offering that began 2026-07-20, filed by president Steven Tuck on 2026-08-04. The company has not disclosed the round's lead, valuation or whether it is a Series D. Oxide continues to deploy racks at CoreSite's SV2 facility, expand manufacturing and court customers with decade-long commitments, and the Hacker News community treats the raise as validation of the on-prem 'cloud ownership' thesis.
