Overview
- Luxor’s Q4 2025 Global Hashrate Map pegs China’s share at roughly 14.05%, translating to about 145 exahashes per second and edging up from 13.8% in Q3.
- The estimate places China behind the United States and Russia, underscoring a continued role despite formal prohibitions that remain in place.
- Luxor derives country shares from mining pool data, ASIC trading flows and firmware adoption, producing snapshots that can shift with methodology and timing.
- Multiple ASIC supply‑chain sources point to Xinjiang as a likely locus for concealed operations, though the map does not specify provincial breakdowns.
- Chinese manufacturers Bitmain, MicroBT and Canaan dominate mining hardware, and industry reports say 55%–65% of global capacity links back to Chinese roots when origin and ownership are counted.
