Bitmain

Bitmain is a semiconductor company founded in 2013 and headquartered in Beijing, China, specialising in the design and manufacture of application-specific integrated circuit (ASIC) chips and mining hardware for cryptocurrency networks. The company is best known for its Antminer product line, a series of ASIC mining servers supporting Bitcoin, Litecoin, Kaspa, and other proof-of-work cryptocurrencies.

Bitmain operates research and development centres in Beijing, Shanghai, Shenzhen, and Singapore, and serves customers in more than 100 countries. In addition to mining hardware, the company produces hydro-cooling solutions such as ANTSPACE containers and ANTRACK cabinets, and offers an after-sales advance replacement service (ASAR) for hardware maintenance. Antpool, a Bitcoin mining pool historically associated with Bitmain, was spun off as a separate entity in 2021.

Bitmain is privately held and has expanded its global footprint with manufacturing and support operations outside China, including a production facility in the United States opened in 2026 to serve North American customers.
