China’s big three BTC miner makers begin U.S. production to dodge tariffs

Bitmain, Canaan and MicroBT — the three largest Bitcoin (BTC) mining rig manufacturers, all based in China — are ramping up production in the U.S. to mitigate the impact of tariffs imposed under President Donald Trump’s trade policy, Reuters reported. Together, the companies control over 90% of the global mining hardware market. Bitmain began production in the U.S. in December 2023, shortly after Trump’s re-election. Canaan launched trial manufacturing in April following the announcement of “Liberation Day” tariffs, while MicroBT is implementing a localization strategy to reduce exposure to trade restrictions. Industry analysts say the U.S.-China trade war is driving structural changes in BTC’s supply chain. While over 30% of BTC mining now occurs in North America, most of the mining equipment is still sourced from China. This heavy reliance has raised national security and supply chain concerns, fueling efforts to shift toward domestic or geopolitically neutral suppliers.
