Three Countries Control 66% of Bitcoin Mining as New Rival Gains Ground

A recent geographical assessment of the global Bitcoin mining ecosystem reveals modest shifts among the world’s mining superpowers, even as overall network concentration remains tightly held. According to Luxor Technology’s mining data platform, Hashrate Index, in its fourth-quarter update—which reflects third-quarter operational metrics rather than a real-time census—the United States experienced a drop in its share of mining computational power, while Russia expanded its footprint and China’s output saw a moderate contraction.

The total computational capacity devoted to the network remained virtually flat, inching from roughly 940 to 941 exahashes per second (EH/s) based on a 30-day simple moving average. However, the internal distribution of that computing power saw notable adjustments. The U.S. share of global hashrate fell from 36.7% to 35.6%. In contrast, Russia captured an increased portion of network capacity, rising from 17.2% to 18.1%. Meanwhile, estimated mining activity in China receded from approximately 115 EH/s to 110 EH/s. Together, the three leading nations saw their joint share edge down from 66.2% to 65.4%—a modest 0.8% decrease that leaves network hashrate heavily concentrated in the same jurisdictions.

Data Methodologies and the Nuance of Jurisdictional Movement

Hashrate Index computes its geographic allocations by applying a weighted model combining mining pool figures, Application-Specific Integrated Circuit (ASIC) hardware trading flows, and firmware adoption indicators. While these metrics provide useful visibility, pinning down the exact physical location of hashrate carries intrinsic challenges. As comparative frameworks like the Cambridge Bitcoin Electricity Consumption Index note, mining pool datasets may lack full representativeness, and proxy networks or virtual private networks (VPNs) can distort geographical tracking.

Crucially, regional shifts in market share do not demonstrate direct cross-border equipment migration. An expansion in Russian hashrate alongside a decline in U.S. metrics indicates relative operational changes—such as machines turning off in one area while new or reactivated units power up elsewhere—rather than a direct hardware relocation from American sites to Russian facilities. Furthermore, the dataset lacks published confidence intervals to establish statistical significance across these reporting intervals.

Physical Location vs. Network Control and Pool Influence

Physical distribution alone does not resolve the broader question of Bitcoin network decentralization. Industry mechanics dictate an important boundary between where computing equipment sits, who exercises beneficial ownership over the physical hardware, and which mining pools coordinate the work.

Under traditional mining protocols like legacy Stratum, mining hardware operators supply raw computing power to a central pool, which subsequently builds block templates and selects transactions. In this arrangement, spreading hardware across disparate geographies does not automatically decentralize transaction selection. While alternative architectures such as Stratum V2 introduce optional mechanisms for individual miners to select their own block-template transactions, widespread implementation remains an ongoing process. Consequently, geographic data alone fails to demonstrate improved ownership diversity or altered operational centralization.

Infrastructure Pivots: Curtailment, AI, and High-Performance Computing

Underlying site-level decisions explain a significant portion of regional hashrate changes. Luxor attributes portions of recent domestic declines to operators shifting infrastructure toward artificial intelligence (AI) and high-performance computing (HPC) hosting. Public filings from digital asset infrastructure firms demonstrate this structural transition in practice.

For instance, in an August 10 operational disclosure, Keel Infrastructure announced that it had completed decommissioning all its U.S. Bitcoin mining operations to make way for HPC construction. Similarly, Core Scientific stated in its July 28 financial reporting that it is undergoing a process of repurposing remaining mining infrastructure for high-density colocation services as market conditions permit. In contrast to temporary curtailments driven by energy pricing or regulatory developments—such as power restrictions identified by Luxor in Ethiopia—reconstructing digital infrastructure for AI represents a durable shift in facility allocation.

Why This Matters

The latest mining distribution figures show that while the geographical distribution of Bitcoin hashrate is shifting between legacy heavyweights, the overall network has not fundamentally broadened its geographic foundation. The persistent concentration across the U.S., Russia, and China highlights that geopolitical and regulatory risks remain clustered within a small set of nations.

Furthermore, the competition for power infrastructure between Bitcoin mining and energy-hungry AI data centers is beginning to leave a measurable imprint on network dynamics. As infrastructure providers convert power-ready capacity to accommodate lucrative HPC workloads, sustaining network growth will increasingly depend on miners tapping emerging energy markets, securing low-cost stranded power, and adopting upgraded protocols that decouple physical hardware sites from transaction-ordering influence.

Frequently Asked Questions

Did Bitcoin mining hardware physically move from the United States to Russia?
No. The data reflects changes in relative market share rather than direct machine transfers. Increases in one country alongside decreases in another typically point to operational shifts—such as machines turning offline in the U.S. while other facilities power up in Russia—rather than the cross-border relocation of equipment.

Does a wider geographic spread of mining rigs make Bitcoin more decentralized?
Not necessarily. The physical location of an ASIC miner is separate from beneficial ownership and mining pool operations. Because mining pools typically determine which transactions are included in new blocks, dispersing physical machines across multiple borders does not automatically decentralize transaction processing or governance power.

Why is the U.S. share of Bitcoin hashrate declining?
The U.S. share reduction is driven by a combination of international growth and domestic infrastructure reallocation. Notably, several prominent infrastructure operators have curtailed operations, faced local power dynamics, or actively decommissioned Bitcoin mining capacity to repurpose power and facilities for AI and high-performance computing workloads.
