The United States’ share of Bitcoin’s hashrate has declined nearly one percentage point from the start of the year through the first 57 days of the third quarter, alongside an estimated reduction of about 55 exahash per second (EH/s) in computing power. Over the same period, major mining hubs such as China and Russia increased their shares of network hashrate.
U.S. Hashrate Share Slips in Early Q3
Industry data indicates that U.S.-based miners collectively saw both their percentage share and absolute computing power dip as Q3 progressed. A decrease of roughly 55 EH/s—where 1 EH/s equals one quintillion hashes per second—suggests a meaningful pullback in active machines or curtailment of mining activity within the country.
China and Russia Capture Larger Slices
While the U.S. eased, mining activity in China and Russia expanded their respective portions of global hashrate. The shift underscores ongoing competition among top jurisdictions to secure low-cost, reliable energy and favorable operating conditions for large-scale Bitcoin mining.
Factors Influencing the Shift
- Power costs and availability: Fluctuating electricity prices and seasonal grid curtailments can temporarily reduce mining uptime in certain regions.
- Post-halving economics: The April 2024 Bitcoin block reward halving tightened miner margins, prompting fleet optimizations, relocations, or shutdowns of less efficient rigs.
- Infrastructure and upgrades: Deployment timelines for new-generation hardware and power capacity additions can shift regional shares quarter to quarter.
- Regulatory and market dynamics: Policy clarity, permitting processes, and access to capital influence where miners expand or consolidate operations.
Why It Matters
Geographic distribution of hashrate affects Bitcoin’s decentralization profile and the resilience of the mining sector to local shocks such as policy changes or energy disruptions. As competitive pressures persist, jurisdictional shares are likely to remain fluid, reflecting where miners can secure the most efficient and stable operating environments.
