Their combined share slipped by about 0.8%, even as the global hashrate estimate stayed almost flat.<\/p>\n<p>That is a modest change in geographic concentration, with a clearer shift in the balance between the two largest mining locations.<\/p>\n<p>Luxor Technology's mining data platform Hashrate Index labels the report its fourth-quarter update, but the figures describe observations from the preceding third quarter. Its <a href=\"https:\/\/hashrateindex.com\/blog\/global-hashrate-heatmap-update-q3-2026\/\">July 16 comparison edition<\/a> described June estimates.<\/p>\n<p>The October publication is neither a completed fourth-quarter result nor a live census of where machines are operating on Oct. 6.<\/p>\n<h2>A smaller US share leaves the same three leaders<\/h2>\n<p>The comparison separates absolute mining activity from network share. Estimated US hashrate declined as its share fell from 36.7% to 35.6%, while Russia gained both estimated hashrate and share, rising from 17.2% to 18.1%. China's estimate declined from about 115 to 110 EH\/s.<\/p>\n<table>\n<thead>\n<tr>\n<th>Location or metric<\/th>\n<th>July edition<\/th>\n<th>October edition<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>United States<\/td>\n<td>About 345 EH\/s; 36.7%<\/td>\n<td>About 335 EH\/s; 35.6%<\/td>\n<\/tr>\n<tr>\n<td>Russia<\/td>\n<td>About 162 EH\/s; 17.2%<\/td>\n<td>About 170 EH\/s; 18.1%<\/td>\n<\/tr>\n<tr>\n<td>China<\/td>\n<td>About 115 EH\/s; 12.2%<\/td>\n<td>About 110 EH\/s; 11.7%<\/td>\n<\/tr>\n<tr>\n<td>Global network<\/td>\n<td>About 940 EH\/s<\/td>\n<td>About 941 EH\/s<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The network total is a 30-day simple moving average of hashrate, the computing work devoted to mining.<\/p>\n<p>The <a href=\"https:\/\/hashrateindex.com\/blog\/top-10-bitcoin-mining-countries-of-2026\/\">provider's methodology summary<\/a> describes a weighted combination of pool data, ASIC trading flows, and firmware adoption trends.<\/p>\n<p>Cambridge's <a href=\"https:\/\/ccaf.io\/cbnsi\/cbeci\/mining_map\/methodology\">separate mining-map methodology<\/a> warns that a pool sample may be unrepresentative and that VPNs or proxies can distort inferred location.<\/p>\n<p>Hashrate Index's October comparison puts the top three countries' combined share at 65.4%, down from 66.2%. Calculating from the rounded EH\/s inputs reproduces approximately that 0.8% decline. The resulting balance leaves the US with a smaller share and Russia with a larger one, while the same three countries remain dominant.<\/p>\n<p>July's printed country shares add to 66.1%, while the rounded EH\/s figures reproduce the provider's 66.2% aggregate after rounding. These differences are distinct from sampling or estimation error, and the comparison provides no confidence range to demonstrate statistical significance.<\/p>\n<figure id=\"attachment_569508\" aria-describedby=\"caption-attachment-569508\" style=\"width: 720px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/10\/exec-8c5daf30-cddb-45cf-b2b0-e0fc83b7948a.png\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"shoggoth-infographic shoggoth-infographic-portrait wp-image-569508\" src=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/10\/exec-8c5daf30-cddb-45cf-b2b0-e0fc83b7948a.png\" alt=\"Hashrate Index's July and October 2026 editions estimate US mining at about 345 then 335 EH\/s, Russia 162 then 170, and China 115 then 110.

Those movements change exposure to particular locations without showing that the network has acquired many more independent sources of mining capacity.<\/p>\n<p>Machines switching off in one country and other machines switching on elsewhere can change the distribution without the same equipment moving between them. The country totals do not establish a transfer from the US to Russia.<\/p>\n<h2>Location leaves ownership and operating status unresolved<\/h2>\n<p>A country's mining share describes where computing activity is estimated to occur, and beneficial ownership asks who ultimately owns that equipment.<\/p>\n<p>Pool control asks who coordinates mining work and selects the transactions proposed for blocks. Treating these as interchangeable would turn a location estimate into a claim about decision-making power.<\/p>\n<p>The <a href=\"https:\/\/cryptoslate.com\/coins\/bitcoin\/\">Bitcoin developer guide's<\/a> pooled-mining explanation separates the miners supplying hashing work from the <a href=\"https:\/\/developer.bitcoin.org\/devguide\/mining.html\">pool that coordinates it<\/a> and distributes rewards. In its legacy Stratum example, miners receive the information needed to construct block headers without being able to inspect or add transactions to the block.<\/p>\n<p>That arrangement makes transaction selection independent of the machines' physical location. Spreading hardware across more countries does not show that more independent parties choose block contents.<\/p>\n<p>Equally, a pool coordinating work is not automatically the beneficial owner of all the equipment contributing to it.<\/p>\n<p><a href=\"https:\/\/stratumprotocol.org\/specification\/02-Design-Goals\/\">Stratum V2's transaction-selection design<\/a> allows miners to choose a transaction set optionally, a capability that does not establish how widely it is used today.<\/p>\n<p>A fuller assessment would need ownership information and contemporaneous evidence about pool participation and block-template selection. The quarterly country figures establish neither improved ownership diversity nor unchanged pool concentration.<\/p>\n\n<div class=\"cs-article-embed\">\n    <a href=\"https:\/\/cryptoslate.com\/solana-beats-bitcoin-on-one-key-metric-but-a-single-software-bug-could-still-take-down-the-network\/\" class=\"cs-article-embed__link\">\n        <div class=\"cs-article-embed__body\">\n            <span class=\"cs-article-embed__related-reading\">Related Reading<\/span>\n            <h3 class=\"cs-article-embed__title\">Solana beats Bitcoin on one key metric, but a single software bug could still take down the network<\/h3>\n        <\/div>\n        <span class=\"cs-article-embed__arrow\" aria-hidden=\"true\">\n            <i class=\"fa-light fa-arrow-up-right\"><\/i>\n        <\/span>\n    <\/a>\n<\/div>\n\n<p>Geography also leaves open what is happening at individual sites. Luxor attributes some regional mining declines to the switch toward artificial intelligence and high-performance computing. Individual company disclosures show that conversion activity is real.<\/p>\n<p>In its <a href=\"https:\/\/investor.bitfarms.com\/news-releases\/news-release-details\/keel-infrastructure-reports-second-quarter-2026-results\">Aug. 10 operational disclosure<\/a>, <a href=\"https:\/\/cryptoslate.com\/companies\/keel-infrastructure\/\">Keel Infrastructure<\/a> said it had completed decommissioning all its US <a href=\"https:\/\/cryptoslate.com\/mining\/\">Bitcoin mining operations<\/a> in preparation for HPC construction.<\/p>\n<p><a href=\"https:\/\/cryptoslate.com\/companies\/core-scientific\/\">Core Scientific's<\/a> July 28 results described an <a href=\"https:\/\/investors.corescientific.com\/news-events\/press-releases\/detail\/139\/core-scientific-announces-second-quarter-2026-results\">ongoing process of repurposing<\/a> its remaining mining facilities for high-density colocation services as circumstances allow. That is a different operating status from a completed mining exit.<\/p>\n<p>These examples substantiate particular companies' actions. Reports on\u00a0<a href=\"https:\/\/cryptoslate.com\/bitcoin-miners-have-amassed-100-billion-of-ai-deals-but-almost-none-of-the-revenue-exists-yet\/\">miners' AI commitments<\/a> examined the execution question before this country comparison appeared.<\/p>\n<p>Temporarily idled equipment may resume work if the conditions that caused curtailment improve. A site being reconstructed or committed to another workload faces a different path back. A hashrate decline alone does not tell readers what happened or how durable it will be.<\/p>\n<p>Luxor also describes an Ethiopian power restriction in explaining that country's decline. Such explanations need their own evidence: a country delta cannot establish the contribution of power rationing, seasonal conditions, or policy. The geographic estimates and the proposed causes remain separate claims.<\/p>\n<p>The network estimate barely changed, from about 940 to 941 EH\/s. That aggregate can coexist with lower US activity because gains elsewhere offset losses, saying little about whether US miners have recovered operating capacity or improved their own economics.<\/p>\n<p>The next useful evidence is specific to the mining risk being assessed: repeated country observations for persistence, company disclosures distinguishing actual conversion from curtailment, and ownership and pool data for control. A single nearly flat network total cannot answer all three.<\/p>\n<p>For now, geographic exposure has shifted within a still concentrated mining network. Establishing broader decentralization gains requires evidence about who owns and coordinates the capacity, as well as where it sits.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hashrate
