BitRiver Bankruptcy Crisis

On January 27, the Sverdlovsk Regional Arbitration Court decided to monitor the Fox Group of Companies LLC, which owns 98% of Bitriver Management Company, in response to a debt claim of $9.2 million from En+'s subsidiary, Infrastructure of Siberia.

This situation reflects a significant downturn for a company that reported over $129 million in revenues last year, utilizing 533 MW of electrical power across 15 data centers housing more than 175,000 mining rigs.

What Led to BitRiver’s Crisis?

Equipment Deal Issues

The bankruptcy petition from Infrastructure Siberia came after BitRiver failed to ship mining equipment for which it had received an advance payment exceeding 700 million rubles ($9.15 million). The company had entered into a supply agreement with Fox Group, but the equipment never materialized, resulting in the cancellation of the contract.

Subsequently, Infrastructure Siberia took legal action to reclaim the advance payment along with penalties for delays. The Arbitration Court of the Irkutsk Region affirmed the claim in April 2025.

However, BitRiver’s owner and CEO, Igor Runets, contests these allegations, insisting that the equipment was indeed delivered and that Fox Group is challenging the court’s decision.

“Although they are functioning normally today, the shutdowns in December incurred significant losses for several companies in the group, including ‘BitRiver Rus’ and ‘Stroyservice Plus,’ which we aim to recover from En+ through legal means,” Runets expressed.

Despite Runets’ assertions, investigations into Fox Group's assets revealed insufficient funds to meet the court-mandated payments, which led to the bankruptcy filing. Meanwhile, due to ongoing legal disputes with En+, the accounts of BitRiver companies were frozen, a legal tactic that could hinder overall business operations.

Compounding Issues: Mining Bans and Energy Disputes

BitRiver’s challenges are compounded by issues beyond debt to En+. Operations in the Irkutsk region were recently halted due to a mining ban enforced in southern areas. A data center with a capacity of 100 MW in Buryatia was never activated, and a comprehensive mining ban is set to commence in the region in 2026.

In February 2025, authorities closed a 40 MW site in Ingushetia that had been operating despite ongoing regulations since early 2025. Additionally, conflicts over unpaid electric bills with energy suppliers are escalating.

Since August 1, 2025, the Faraday Group’s energy sales division was stripped of its rights to partake in electricity trading and its wholesale market status has been suspended. Courts are reviewing claims for unpaid penalties totaling 133 million rubles ($1.74 million) from En+ Sbyt and 640 million rubles ($8.37 million) from the Irkutsk Electric Grid Company for overdue payments under energy contracts.

Trouble for CEO Amid Downfall

In the midst of these unfolding challenges, BitRiver's founder and CEO, Igor Runets, was detained by Russian authorities and faces charges of tax evasion involving three counts related to allegedly concealing assets to evade tax obligations.

Runets has been placed under house arrest, with his legal team permitted until Wednesday to contest the ruling.

BitRiver has been under increasing scrutiny during recent years after facing sanctions from the US Treasury Department in mid-2022 due to its association with Russia amidst the Ukraine conflict. This action has limited access to Western markets and business partners. In 2023, the Japanese financial group SBI severed its relationship with BitRiver as it exited the Russian market.

Despite the company's collapse, there is still rising demand for mining infrastructure across Russia. The System Operator reported that the capacity of miners and data centers connected to the grid grew by 33% in 2025, reaching 4 GW.

Russian Data Center Market Growth

Projections indicate that by 2031, the annual growth rate of the data center market in Russia may reach 14.41%.
