Three of China’s biggest Bitcoin hardware makers have quietly set up shop in the US, trying to dodge hefty import fees. Bitmain, Canaan and MicroBT together control over 90% of the world’s mining rigs.
Their move comes after US President Donald Trump slapped new tariffs on Chinese goods, a shift that could reroute the very backbone of Bitcoin mining.
Based on a report by Reuters, Bitmain kicked off US production in December, one month after Trump’s election victory. Canaan followed on April 2 with trial runs. MicroBT says it’s “actively implementing a localization strategy in the US.”
Frost & Sullivan’s 2024 white paper finds these three companies hold a combined 95% of the global ASIC market by computing power sold. That level of consolidation is rare in tech.
Analysts see the market growing at 15% CAGR, to hit nearly $12 billion by 2028. With that kind of money on the table, it’s no surprise Chinese outfits dominate.
US miners handle almost 40% of global Bitcoin mining, but almost all their rigs still trace back to Chinese engineers. Critics call this a “digital dependency trap.”
Conflux Network’s CTO Guang Yang warns the trade fight isn’t just about money. He says it’s also about “politically acceptable” hardware.
Some fear Chinese‑built machines — even if assembled in the US — could hide backdoors or tricky firmware.
Some people might wonder if the US can break free. A few start‑ups have sprouted in Silicon Valley and Texas. They aim to design ASIC chips on American soil.
But beating firms with years of experience and state‑of‑the‑art fabrication ties won’t be easy. And right now, US miners need rigs in hand, not promises of future prototypes.
Miners say they’ll enjoy faster deliveries and dodge sudden cost hikes. Yet deeper questions linger. Will this shift spark real innovation in US chip design, or simply turn Chinese blueprints into “Made in USA” labels?
Some industry watchers think the latter. They point to past moves in solar panels and telecom gear, where assembly moved overseas without true tech transfer.
