U.S. share of Bitcoin mining falls…Global landscape upended as miners pivot to AI

The influence of North America—led by the United States—over Bitcoin mining is waning as investment pours into artificial intelligence (AI) infrastructure and profitability deteriorates, reshaping the global mining map.

According to Decrypt on the 15th (local time), BlocksBridge Consulting analyzed that the block share generated by North America-based Bitcoin mining pools declined steadily throughout 2025. As of last December, the combined share of Foundry USA, MARA Pool, and Luxor Technologies was tallied at about 35%, down from levels above 40% in January 2025.

The trend contrasts with U.S. President Donald Trump’s campaign message emphasizing securing leadership in Bitcoin mining. While American Bitcoin—a mining company co-founded by the Trump family—has also been expanding its business, analysts say that across the North American mining industry, capital and electricity are shifting toward AI data-center investment.

Hut 8, in particular, is accelerating a pivot away from a Bitcoin mining-focused strategy toward becoming an energy and AI infrastructure company. Hut 8 said last December that it would work with AI company Anthropic to build large-scale data-center infrastructure in the United States.

Deteriorating mining profitability is also cited as a driver of structural change. According to JPMorgan, the average daily revenue of Bitcoin miners in December last year was $38,700 per EH/s, down 32% year over year. With rising power costs and intensifying competition squeezing mining margins, many operators are said to be turning their focus to high-performance computing (HPC) and AI demand.

Meanwhile, there are also signs that regions such as China, the Middle East, and Russia are again expanding their share of Bitcoin hashrate. BlocksBridge Consulting said that upgrades to China’s power infrastructure are another factor behind North America’s declining share. China banned Bitcoin mining in 2021, but unofficial mining activity is reportedly continuing, centered on the Xinjiang region.

The mining hardware market is also entering a period of change. Bitmain, which holds roughly 80% of the global mining equipment market, is said to be increasing the share of its own in-house mining as equipment demand cools. Some also speculate that if oversupply of equipment persists, it could weigh on semiconductor foundry capacity allocations as well.
