Bitcoin Mining Sees Major Shift as Chinese Giants Move Operations to US

Highlights:

• Chinese Bitcoin mining firms are moving production to the US to avoid high tariffs and maintain market access.
• US-listed Bitcoin miners now contribute over 31% of the global hashrate.
• US firms have raised concerns about Chinese mining rigs posing risks to national power grids and hardware supply chains.

Bitmain, Canaan, and MicroBT are shifting their Bitcoin mining hardware production to the United States. According to a report by Reuters, this move follows the reimposition of tariffs by President Donald Trump. These tariffs target imports from China, including advanced technology products. As a result, major crypto hardware producers are now moving operations to avoid higher costs and maintain access to the U.S. market.

Bitmain, which holds the largest market share, started production in the United States last December. This decision came soon after Trump secured a second term in office. Canaan was next to embark on early-stage trials to determine the long-term viability of doing so in the U.S. market. MicroBT has also declared a localization policy that will lower exposure to cross-border trade tension.

The combined production of these three companies exceeds 90% of all Bitcoin mining rigs in the world. Their move into the U.S. indicates tremendous changes in the crypto mining hardware supply chain. Although the decision can limit tariff expenses, it also increases security issues given the historical feuds in the technology sector.

US Firms Expand Role in Bitcoin Mining

Meanwhile, the U.S. hashrate share in global Bitcoin mining continues to rise. On June 17, Mathew Sigel from VanEck shared data showing that U.S.-listed miners now contribute 31.6% of the global total. This figure represents a sharp increase from April 2024, when the share was just 21%.

The growth is also at a time when different manufacturers from China are penetrating the U.S. market in order to stay competitive. The three companies are responding to economic and political pressure by engaging in domestic construction. Their presence supports the growing U.S. mining infrastructure, which benefits from favorable policy directions and increased investor interest.

Data from the University of Cambridge reveals the market dominance of these three firms. Bitmain accounts for 82% of global ASIC production, MicroBT for 15%, and Canaan for 2%. Collectively, they dominate most of the output of Bitcoin mining rigs. This dominance is also behind their preference to remain near the emerging U.S. mining hub.

In the past, Bitmain experienced delays at the United States border. In November 2024, customs seized several thousand Bitmain ASICs because of a probe on its chip supplier. These units were not released until March, after several months of inspection. The experience likely contributed to the company’s current strategy of producing hardware within the United States.

Security Risks Surface Over Hardware Origin

Despite the economic shift, some U.S. stakeholders have raised concerns about national security. Auradine, an American mining company financed by MARA Holdings, has urged less use of Chinese hardware. According to Sanjay Gupta, the chief strategy officer at Auradine, most Bitcoin is mined in the U.S. However, more than 90% of the equipment originates in China. He noted that the existence of the Chinese-produced mining rigs that are linked to the U.S. power grid posed a threat. These objections echo wider discussions on the use of foreign technology in sensitive industries.
