The global landscape of bitcoin mining machines is undergoing significant changes as the world’s top three manufacturers, all of Chinese origin, are establishing manufacturing bases in the United States. This shift comes in response to President Donald Trump’s trade war tariffs, which are reshaping the cryptocurrency supply chain.
Bitmain, Canaan, and MicroBT, which collectively produce over 90% of the world’s mining rigs, are looking to set up production facilities in the U.S. to avoid tariffs and mitigate risks associated with security concerns related to Chinese manufacturers. This strategic move reflects a structural change in bitcoin’s supply chain, according to Guang Yang, chief technology officer at Conflux Network.
The U.S.-China trade tensions have prompted these companies to pivot towards politically acceptable hardware sources, beyond just tariff considerations. Bitmain, the largest of the three manufacturers, initiated U.S. production of mining rigs in December as a strategic response to Trump’s electoral victory.
Canaan has also begun trial production in the U.S. in an effort to circumvent tariffs imposed by the U.S. government. MicroBT is actively pursuing a localization strategy in the U.S. to minimize the impact of tariffs on their operations.
The dominance of these three manufacturers in the global hardware market, estimated to reach $12 billion by 2028, has raised concerns about the geographic imbalance in supply and demand. U.S. rival Auradine, backed by MARA Holdings, is advocating for restrictions on Chinese supplies to promote competition in the hardware sector.
While Chinese mining rigs have been a major player in the industry, concerns about security risks associated with hundreds of thousands of these rigs connected to the U.S. electrical grid have been raised. Canaan’s Leo Wang asserts that mining rigs do not pose a security threat as they are specifically designed for bitcoin mining.
However, manufacturers like Bitmain could face collateral damage from U.S. restrictions on high-tech sales to Chinese firms. Bitmain’s AI affiliate, Sophgo, has already been blacklisted by the U.S. government on security grounds, underscoring the potential risks associated with Chinese manufacturers.
The U.S. government’s emphasis on promoting cryptocurrency adoption and mainstream use may further highlight China’s significant role in bitcoin infrastructure. This could potentially put Chinese rig makers in a vulnerable position, given the U.S.’s increasing focus on crypto-friendly policies.
As the industry continues to evolve, the establishment of manufacturing bases in the U.S. by Chinese manufacturers signifies a pivotal moment in the bitcoin supply chain. This shift not only addresses tariff concerns but also reflects a broader strategic realignment in response to geopolitical and security considerations.
