Catenaa, Wednesday, June 25, 2025- The world’s three leading bitcoin mining machine manufacturers, all Chinese, Bitmain, Canaan, and MicroBT, are establishing production facilities in the United States to sidestep tariffs imposed amid ongoing US-China trade tensions, Reuters reported.
These firms control over 90% of the global mining rig market, vital hardware that powers bitcoin mining worldwide. By localizing manufacturing in the US, they aim to reduce tariff costs introduced by the Trump administration and maintain market dominance despite increasing geopolitical risks.
Bitmain began US production in December 2024, shortly after tariffs were announced. Canaan is conducting trial production, while MicroBT is actively pursuing localization.
espite the shift, concerns remain over the security risks posed by reliance on Chinese-made rigs, which make up the vast majority of mining hardware connected to the US power grid.
Experts warn that dependency on Chinese hardware creates a strategic vulnerability for US miners and the broader bitcoin network. Restrictions or supply disruptions from China could threaten network stability and impact American users and investors.
Meanwhile, US companies like Auradine are lobbying for measures to curb Chinese dominance and boost domestic competition.
China once dominated the entire bitcoin ecosystem until its 2021 crypto crackdown. The hardware makers have since expanded globally, with Canaan relocating headquarters to Singapore and tapping into the US market, which accounts for 40% of its revenue.
The ongoing tariff war and political tensions are accelerating a structural shift in bitcoin’s supply chains as the industry adapts to a new geopolitical reality.
