AI fever hits the mining industry

Most major mining companies have come to the same conclusion: diversification is essential. After years of dependence on Bitcoin’s price cycles and energy costs, the industry has finally found a way to use its infrastructure more flexibly.

One of the most notable cases is IREN, which signed a multi-year $9.7 billion contract with Microsoft. Under the agreement, the company will provide Microsoft access to its computing capacity, which will be used for the corporation’s cloud-based AI services. At the same time, IREN is building a 750 MW campus in Texas featuring liquid-cooling systems and a 200 MW IT load.

A similar direction was taken by Cipher Mining, which signed a 10-year, $3 billion deal with Fluidstack, backed by Google as a guarantor. Cipher will allocate 168 MW of capacity for high-performance computing (HPC) projects, while Google — receiving warrants for shares — effectively becomes a strategic investor.

Riot Platforms is also following this path. Despite posting a record $104.5 million profit in Q3, the company announced a shift of part of its capacity toward AI. Riot paused Bitcoin mining expansion at its 1 GW site in Corsicana and has already repurposed 126 MW for data centers serving neural-network workloads. “We no longer see mining as an end in itself, but as a way to maximize the value of our megawatts,” the company said.

The global AI race and the miners’ role

Viewed more broadly, the world is now in the midst of a genuine race for AI leadership — and the role of mining companies in it can hardly be overstated. China currently holds the lead, but the balance of power could shift at any moment.

Nvidia CEO Jensen Huang told the Financial Times that China is ahead of the U.S. in AI development, thanks to cheap electricity and flexible regulation. He noted that the Chinese government subsidizes power for data centers, making domestic chips from Huawei and Cambricon highly cost-effective. “In China, energy is practically free,” Huang said, adding that this allows the country to scale AI clusters at unprecedented speed.

At the same time, technological progress in the West is slowed by bureaucracy and excessive caution, which, according to Huang, “stifle innovation.” The situation is further complicated by the Trump administration’s ongoing ban on selling Nvidia’s latest Blackwell processors to China. Despite negotiations between Washington and Beijing, the White House has refused to lift restrictions, citing national security concerns.

A new meaning of energy

Against this backdrop, mining companies now sit at the crossroads of energy, politics, and technology. They possess what even AI giants lack — cheap electricity, large-scale infrastructure, and deep expertise in managing distributed computing.

Once dependent on Bitcoin’s price swings and halving cycles, miners have become a core pillar of the digital economy. Their infrastructure now forms a bridge between energy and intelligence — the two defining assets of the 21st century. Once they mined digital gold; now, they generate the computational fuel powering the next technological era.
