Key Points
- Bitmain, Canaan, and MicroBT established production facilities in the US to avoid Trump tariffs.
- The companies account for over 90% of the global market share.
According to the latest reports from Reuters, the world’s dominant Bitcoin mining machine makers, Bitmain, Canaan, and MicroBTC, have set up production facilities in the US in order to avoid the US President Donald Trump’s tariffs.
Bitmain, Canaan, MicroBT Built Over 90% of the Global Mining Rigs
The publication noted that the three companies account for more than 90% of the global market share in Bitcoin mining rigs. They dominate a sector which is estimated to be worth $12 billion by 2028.
The establishment of US facilities could shield them from Trump’s tariffs, but it could also risk security concerns the US has with China in various areas, including chip-making and energy security.
Guang Yang, the CTO at crypto tech provider Conflux Network, believes that the US-China trade war is triggering structural changes in Bitcoin supply chains. He said that this goes beyond tariffs and it’s a strategic pivot towards “politcally acceptable” hardware sources.
Bitmain, which is the biggest of the three companies by sales, has reportedly debuted its US mining rigs products in December 2024 in a strategic move.
Canaan started the production in the US to avoid Trump’s tariffs imposed on April 2, 2025 on the so-called “Liberation Day”, the senior executive of the company, Leo Wang told the publication. He also said that the mining rigs don’t threaten security, as they’re useless if not applied to BTC mining.
MicroBT said that it’s actively implementing a localisation strategy in the US to avoid tariff impact.
Reuters also noted that the US rival Auradine, which is backed by the top BTC miner by market value, MARA, has been lobbying to restrict Chinese supplies to stimulate competition in hardware.
Potential Issues With Chinese Mining Hardware Domination
Auradine’s chief strategy officer, Sanjay Gupta, said that while over 30% of the global BTC mining takes place in North America, more than 90% of mining hardware originates from China, which represents an imbalance of geographic demand and supply.
He also said that hundreds of thousands of Chinese mining rigs are connected to the US electrical grid.
Meanwhile, a US crypto law attorney said that China’s hardware dominance creates a choke point for the US miners, and if China restricts exports or manipulates supply, this could disrupt Bitcoin’s network stability, affecting US users and investors.
China used to dominate the entire Bitcoin value chain, from rig-making to mining and trading, until the government banned crypto activity on the Chinese mainland in 2021, due to “risks to financial stability.”
