Winter Storm Forces Major US Bitcoin Mining Pools to Cut Over 110 EH/s

An Arctic winter storm prompted major U.S. Bitcoin mining pools to sharply curtail operations, with Foundry USA and Luxor collectively cutting more than 110 exahashes per second of hashrate in late January 2026 ^[1].

The loss of mining capacity coincided with reports of delayed block production — block times were reported to have stretched past 12 minutes as U.S. mining activity fell ^[2].

Multiple news outlets and community posts characterized the weather event as a deadly winter storm that disrupted grids and affected mining facilities and pools across the U.S. ^[3][4].

Taken together, the reports attribute roughly a 110 EH/s reduction in U.S. Bitcoin mining capacity to the storm and link that reduction to temporary network slowdowns, according to the cited sources ^[1][2].
