Deno's Team Joins Cloudflare, and Profitable Oxide Raises $445 Million
The JavaScript runtime company is folding into Cloudflare, winding down its hosting service. Server maker Oxide raised a Series D because orders outrun supply. Cloudflare's post carries an Acquisitions tag, though neither company's text uses the word.
Two announcements on October 9 arrived together. One company's team joined a giant; the other raised a large round because it could not build machines fast enough.
Cloudflare and Deno published matching posts on October 9, 2026. Deno creator Ryan Dahl wrote that the entire Deno team is joining Cloudflare. Neither side disclosed financial terms, and neither post uses the word acquisition in its body text. The Cloudflare post is filed under an 'Acquisitions' tag, and The New Stack, BetaNews and others reported the deal as an acquisition.
The goal is to make Cloudflare's Workers programming model a mainstream way to build servers. Dahl and Bert Belder will lead an effort to make self-hosting workerd, Cloudflare's open-source runtime, a supported option. They will merge in ideas from celld, a self-hostable system Deno released in August.
There are real consequences for current users. According to Deno's post, Deno will continue monthly bug-fix and security releases of the runtime for one year, after which development ends. The runtime stays open source. Deno Deploy, the company's hosting service, will run for six months and then shut down, with migration help for paying customers. The JSR package registry continues on Cloudflare infrastructure.
celld matters to the logic of the deal. Deno creator Ryan Dahl describes it as a single Rust program whose only outside dependency is object storage. It lets developers run Workers-style distributed applications on their own machines. Folding it into workerd gives Cloudflare a credible answer for customers who want the same programming model off its cloud.
Oxide Computer, which builds rack-scale servers for companies that run their own data centers, announced a $445 million Series D on October 9. Eclipse led. USIT, Riot Ventures and Jane Street took large allocations. Atreides Management joined as a new investor, and AMD came in as a strategic investor.
The reason for raising is unusual. Oxide says it paid income tax in the spring, earned from ordinary sales after component, manufacturing and salary costs. It describes a very large order backlog, with demand far exceeding supply. Hardware requires paying for parts and manufacturing long before customers pay. Without new capital, Oxide says, it would have had to be cautious about taking new orders.
The pace is notable. Oxide announced a $200 million Series C in February 2026, so this round arrives about eight months later. In a company FAQ, CEO Steve Tuck said Oxide turned profitable and that demand continues to outstrip supply. The constraint, he suggested, is securing parts such as memory, storage and electrical components.
Medical AI, hospital software and research computing all sit on this layer. When a platform absorbs an independent runtime, users gain stability but lose a choice, and the Deno runtime's development ends after one year.
Oxide's claims about profit and backlog are company statements; it gave no figures. Treat them as signals, not audited facts. Not financial advice.
• Our summary said Cloudflare acquired Deno. The companies describe the team joining Cloudflare and disclose no deal terms. • The summary omitted that Deno Deploy will shut down in six months and runtime development will end after a year of maintenance releases. • The summary said Oxide would have had to ration orders; Oxide's wording is that it would need to be cautious about accepting new demand.
• How Deno Deploy customers migrate before the six-month shutdown. • Whether a community fork keeps the Deno runtime developing after next year. • Oxide's manufacturing ramp, and whether large health systems appear among its customers.
