The United States, Russia and China collectively controlled 67.5% of global Bitcoin hashrate in Q4 2025, according to Hashrate Index’s quarterly heatmap, underscoring a persistent concentration of mining power among just three nations even as the network’s total hashrate approaches 924 EH/s.
Hashrate Index’s Q4 2025 Data Put the US, Russia and China at 67.5% Combined
The Q4 2025 Global Hashrate Heatmap, published on October 6, 2025, ranked the United States first with 37.8% of global Bitcoin hashrate. Russia came second at 15.5%, and China third at 14.1%.
Those three countries combined for 67.5% of the network’s total computing power, closely matching the “~68%” figure that circulated across social media in recent weeks. The distinction matters: the precise dataset behind the claim is a specific quarterly snapshot, not a live measure of mining distribution.
CoinShares’ Q1 2026 Bitcoin Mining Report repeated the concentration claim, citing Hashrate Index as its source for the geographic breakdown. The secondary confirmation from a major research firm lends additional weight to the underlying dataset.
What China’s Continued Presence Says About Mining Geography
The United States’ dominance at 37.8% is expected. Large-scale public miners such as Marathon Digital and Riot Platforms operate significant facilities in Texas and other energy-rich states, and favorable regulatory clarity has attracted institutional capital to U.S.-based operations.
China’s 14.1% share is the more surprising figure. Beijing formally banned domestic cryptocurrency mining in September 2021, yet Hashrate Index data shows Chinese miners still accounted for a significant portion of the network more than four years later. Research context attributes this persistence to underground operations and cross-border mining arrangements.
The situation has since shifted. Hashrate Index’s Q1 2026 update, published January 12, 2026, reported that China’s share fell to 11.7% following renewed crackdowns in Xinjiang province during December 2025. That 14% quarter-over-quarter decline suggests enforcement pressure is having a measurable, if delayed, effect on China’s mining footprint.
Russia’s second-place ranking at 15.5% reflects a different dynamic. Russian miners benefit from low energy costs and cold climates that reduce cooling expenses, and the country has moved toward a more structured regulatory framework for mining operations. As geopolitical tensions around regulatory jurisdiction over digital assets intensify globally, mining geography has become a proxy for broader national strategy.
Why the ‘~68%’ Claim Needs a Date Stamp
The concentration story is real, but the numbers are time-sensitive. Hashrate Index’s newer Q1 2026 heatmap still ranks the United States, Russia and China as the top three mining countries. Their combined share, however, slipped to 65.6%, a nearly two-percentage-point decline from Q4 2025.
Presenting “~68%” as a current figure without the Q4 2025 timestamp is misleading. The verified data supports that claim only for the specific quarter in which Hashrate Index measured it. By Q1 2026, the concentration had already loosened, likely driven in part by China’s Xinjiang enforcement and gradual hashrate growth in emerging mining jurisdictions.
The top-three ranking itself remained unchanged across both quarters, which confirms the structural pattern: a small number of countries continue to host the vast majority of Bitcoin’s mining infrastructure. Whether that concentration is a regulatory concern or simply a reflection of energy economics depends on the policy lens applied.
Bitcoin traded at $66,932 with a market capitalization of roughly $1.34 trillion at the time of the data collection, amid an environment where the Fear and Greed Index sat at 12, firmly in “Extreme Fear” territory. That risk-off sentiment has not slowed hashrate growth, with the network operating at approximately 924 EH/s.
For readers tracking broader security risks in the crypto ecosystem, the mining concentration data adds another dimension. A network where three countries control roughly two-thirds of hashrate faces different resilience questions than one with a more distributed geographic base. The Q1 2026 decline to 65.6% suggests a slow, uneven trend toward decentralization, but any single quarter’s enforcement action in China or policy shift in the U.S. could reverse it.
