Hut 8 deepens Bitmain partnership with launch of new ASIC miner in 2025

Bitcoin miner Hut 8 is expanding its partnership with Bitmain to introduce a new ASIC miner with direct liquid-to-chip cooling, set to deploy in Q2 2025.

Miami-headquartered crypto mining firm Hut 8 has expanded its partnership with Bitmain, announcing the upcoming launch of the U3S21EXPH, a next-generation ASIC miner capable of reaching up to 860 TH/s.

In a Sept. 19 press release, the company the miner, which is scheduled for deployment in Q2 2025, is the first mass-commercialized ASIC model to feature direct liquid-to-chip cooling in a U-form factor.

“We believe this model represents a more thoughtful approach to capturing the lucrative economics offered by next-generation machines, reducing upfront capital requirements while we continue to pursue growth initiatives in AI infrastructure.”

Under the hosting agreement, Hut 8 has the option to purchase all or a portion of the hosted miners in up to three tranches at a fixed price within six months of deployment. If Hut 8 exercises the option in full, the company’s self-mining hashrate is expected to increase from 5.6 EH/s to 20.6 EH/s, the press release reads.

The agreement is designed to minimize upfront capital expenditures and provide flexibility for future purchases, allowing Hut 8 to assess market conditions “before committing additional capital,” per the document.

The news comes after Hut 8 secured a $150 million investment in June from Coatue Management to accelerate its artificial intelligence infrastructure development. At the time, Hut 8 said the investment was made as “many traditional data center operators are failing to meet the surging demand for AI compute capacity due to power shortages.”
