Iran had 427,000 active Bitcoin mining rigs. Now most of them are dark.
Q2 2026 data from Hashrate Index puts the damage at 77%. Iran’s Bitcoin hashrate went from 9 EH/s to roughly 2 EH/s in a single quarter. Seven exahashes per second, erased. Ian Philpot, marketing director at Luxor Technology, confirmed the numbers in a report published Monday. The cause is not complicated. Conflict with the U.S. and Israel shredded the energy infrastructure that Iranian Bitcoin mining ran on.
How Iran Became a Bitcoin Mining Hub
Iran legalised crypto mining back in 2019. Licensed operators got access to subsidised electricity in exchange for selling mined BTC to the central bank. That deal made economic sense for miners. Cheap power, legitimate legal cover, and massive scale.
At its peak, Iran was pulling close to 9 EH/s in Bitcoin hashrate contribution. Chainalysis pegged Iran’s total crypto ecosystem at $7.78 billion in 2025. The IRGC reportedly controlled over 50% of those inflows. Bitcoin mining was not a hobby operation there. It was state-adjacent infrastructure.

War Killed the Power. Power Killed the Mining.
U.S. and Israeli strikes on Iran began in February 2026. The country’s power grid took pressure fast. When conflict damages infrastructure, mining output drops in the short term, and that is exactly what happened here. Bitcoin mining does not tolerate unstable electricity. Rigs need continuous, cheap power to stay profitable. Take that away, and the economy collapses overnight.
Iran’s two closest neighbors, the UAE and Oman, showed no measurable Bitcoin hashrate disruption even as the regional conflict escalated sharply. The damage stayed inside Iran’s borders. Philpot noted this specifically: the global Bitcoin hashrate at roughly 1,000 EH/s held because no single region carries enough weight to threaten the broader network.
Bitcoin Hashrate Globally: Barely Moved
The 30-day simple moving average of global Bitcoin hashrate declined from 1,066 EH/s in Q1 to around 1,004 EH/s in Q2, a 5.8% quarter-over-quarter decline. That number is not alarming on its own. But the reason matters.
Philpot was direct about it. The bigger driver of the global Bitcoin hashrate dip is not geopolitics. Bitcoin is down more than 45% from its October all-time high of $126,000, pushing hash prices to record lows and knocking an estimated 252 EH/s of marginal capacity offline. Old equipment running slim margins got switched off. That happens in every down cycle.
Iran was a special case on top of that.

Who Controls Bitcoin Hashrate Right Now
Three countries still dominate, and the numbers have not shifted much. The U.S. leads with 37.5% of global hashrate, followed by Russia at 16.4% and China at 11.7%. Together that is about 65% of all Bitcoin mining power sitting in three countries with complicated geopolitical histories.
Iran’s exit barely registered at the network level. At 9 EH/s peak, it held under 1% of the total global Bitcoin hashrate. Small enough that the network absorbed the loss without blinking. The U.S. at 37% is a very different conversation.
Smaller markets are quietly growing. Paraguay runs almost entirely on hydro. Ethiopia is over 90% hydro too. Kazakhstan, Norway, Iceland, none of these grids move meaningfully in step with crude oil prices. That kind of energy stability is exactly what long-term Bitcoin mining operations need.
What Iran’s Collapse Actually Tells You
Bitcoin’s hashrate typically marches upward. Repeated downward adjustments just do not happen, according to Blockspace co-host Colin Harper. Yet that is what 2026 has delivered so far.
Iran’s situation is part of a wider story. Miners running old equipment cannot survive low Bitcoin prices. Conflict accelerated what a low hash price was already doing in Iran. The global hashrate decline is driven primarily by falling Bitcoin prices, not geopolitical shocks. Iran just had both at once.
Mining follows profitability. When a country stops being cheap enough, miners leave or shut down. War made Iran’s cheap power disappear overnight. The rigs went quiet. And 77% of a nation’s Bitcoin mining sector went with it.

Why did Iran’s Bitcoin hashrate fall 77% in Q2 2026?
Military conflict with the U.S. and Israel damaged Iran’s power infrastructure. Bitcoin mining depends on stable, cheap electricity. Once that broke down, large-scale operations shut off fast.
Did this affect the global Bitcoin network seriously?
Not really. Global Bitcoin hashrate fell 5.8% from 1,066 EH/s to 1,004 EH/s. Analysts at Luxor Technology say the bigger factor was falling Bitcoin prices, not the conflict itself.
Which countries lead Bitcoin mining globally today?
The U.S. at 37.5%, Russia at 16.4%, and China at 11.7%. Those three account for roughly 65% of all Bitcoin mining activity worldwide.
Could the Iranian mining sector recover?
A ceasefire was reportedly agreed on April 8, 2026. But rebuilding mining infrastructure takes time. Short-term recovery looks slow even if stability returns.
