Bitcoin miners chase AI demand as Nvidia says Rubin is already in production

Nvidia CEO Jensen Huang said the company’s next-generation Vera Rubin platform is already in “full production,” unveiling fresh details at CES in Las Vegas about hardware that he says can deliver five times the artificial-intelligence computing of Nvidia’s previous systems.

Rubin is expected to arrive later this year and is aimed squarely at the fastest-growing part of the AI business, helping to deliver outputs from trained models.

Huang said Rubin’s flagship server will include 72 of Nvidia’s graphics processing units and 36 central processors, and can be linked into larger “pods” containing more than 1,000 Rubin chips.

Much of the talk was about efficiency. Huang said Rubin systems could improve the efficiency of generating AI “tokens” — the basic units produced by language models — by roughly 10 times, helped by a proprietary type of data the company wants the broader industry to adopt. He added that the performance jump comes despite only a 1.6-times increase in transistor count.

Huang described AI development as a race where faster processing means reaching the next milestone sooner, forcing competitors to spend aggressively on chips, networking and storage.

How bitcoin miners are impacted

That same infrastructure race has been reshaping parts of the crypto market too.

Bitcoin miners have increasingly marketed themselves as power-and-rackspace operators rather than pure crypto plays, pitching their energy contracts, cooling capacity and data-center footprints to AI customers.

Hosting AI workloads can generate steadier cash flows than bitcoin mining during down cycles, especially for firms with cheap power, existing sites and cooling capacity.

But the AI boom also raises the bar. Data-center space is becoming a premium asset, and the best sites get bid up by hyperscalers, cloud firms and AI startups.

That can lift rents, equipment costs and financing hurdles for smaller miners. In other words, miners that look like infrastructure companies may win, while those that rely on pure mining margins face a tougher 2026.

Meanwhile, Nvidia also highlighted new networking switches using a connection method called co-packaged optics, a key technology for linking thousands of machines into a single system.

The company said CoreWeave will be among the first to receive Rubin systems, and expects Microsoft, Oracle, Amazon and Alphabet to adopt them as well.
