BitRiver CEO Arrested; Russia’s Mining Empire Collapses Into Bankruptcy
BitRiver founder Igor Runets is detained on tax charges as an En+ lawsuit pushes Russia’s largest miner into bankruptcy proceedings.
Igor Runets, the founder of Russia’s largest crypto mining operator BitRiver, has been placed under house arrest in Moscow on tax evasion charges, marking the probable end for the once-dominant firm. The arrest coincides with insolvency proceedings against BitRiver’s parent company, Fox Group, following a lawsuit by En+ Group over unpaid energy debts.
The collapse of Russia’s mining hegemon sent ripples through the sector as Bitcoin struggled to hold $78,300 (-6.6%) amid broader market volatility.
The Insolvency Cascade
While Runets was detained by law enforcement on January 30, the real blow to BitRiver’s operations came days earlier. The Sverdlovsk Arbitration Court initiated bankruptcy supervision against Fox Group of Companies LLC, which owns 98% of BitRiver, after the firm failed to settle a $9.2 million (700 million ruble) claim from En+ Group subsidiary, Infrastructure of Siberia.
The debt stems from an equipment supply contract where BitRiver accepted advance payments but failed to deliver the hardware. With accounts now frozen, the company’s ability to service its 533-megawatt capacity across 15 data centers has effectively vanished.
Sanctions and Exodus
The fall of BitRiver was slow, then sudden. Sanctioned by the U.S. Treasury in 2022 following the invasion of Ukraine, the firm was cut off from Western capital and hardware markets. The liquidity crunch became undeniable in late 2025, when 80% of senior management resigned and regional offices began closing.
“Runets is accused of concealing assets to evade taxes… His legal team has a small window to appeal before the order becomes fully enforceable on Wednesday.”
Runets, whose net worth was estimated at $230 million just months ago, now faces up to six years in prison if convicted on the tax charges. The Zamoskvoretsky District Court ordered house arrest until at least April, pending the investigation.
Market Impact
BitRiver once controlled over half of Russia’s industrial mining capacity. Its insolvency leaves a massive power vacuum in the region, likely forcing smaller miners to scramble for new hosting agreements with state-backed energy providers like Rosatom. For now, the hardware is offline, and the hash rate is gone.
