Russia’s Largest Bitcoin Miner BitRiver Faces Bankruptcy Crisis – What Went Wrong?

BitRiver, Russia’s largest Bitcoin miner, controlling over 50% of the nation’s mining market, is spiraling toward bankruptcy after a court instituted observation proceedings against its parent company.

The Sverdlovsk Regional Arbitration Court ruled on January 27 to begin monitoring Fox Group of Companies LLC, which owns 98% of Bitriver Management Company, following a $9.2 million debt claim from En+ subsidiary Infrastructure of Siberia.

The crisis marks a dramatic reversal for a company that generated over $129 million in revenue last year and operated 533 MW of electrical power across 15 data centers with more than 175,000 mining rigs.

Equipment Deal Went Wrong For BitRiver

Infrastructure Siberia filed the bankruptcy petition after BitRiver failed to deliver mining equipment despite receiving an advance payment exceeding 700 million rubles ($9.15 million).

The company signed an equipment supply contract with Fox Group, but the hardware never arrived, leading to the contract’s termination.

Infrastructure Siberia filed a lawsuit demanding a refund of the advance payment plus penalties for late payment. In April 2025, the Arbitration Court of the Irkutsk Region upheld the claim in full.

However, BitRiver’s owner and CEO, Igor Runets, disputes the allegations.

According to Forklog, Runets asserts that the equipment was delivered, and GC “Fox” is appealing the court’s decision.

“Today they are operating normally, but the shutdowns in December caused significant losses to several group companies, including ‘BitRiver Rus’ and ‘Stroyservice Plus,’ which we also plan to recover from En+ through legal proceedings,” Runets stated.

Despite Runets’ claims, enforcement proceedings against Fox Group uncovered no assets sufficient to cover the court-ordered claims, prompting the bankruptcy filing.

As part of legal disputes between En+ structures and BitRiver companies, the defendants’ accounts were frozen, a move lawyers warned could paralyze the entire business operation.

Mining Bans and Energy Disputes Compound Problems

BitRiver’s troubles extend far beyond the En+ debt. Sites located in the Irkutsk region are no longer operational following the introduction of a mining ban in the region’s south.

A 100 MW data center in Buryatia was never commissioned, and a year-round mining ban will take effect in the region starting in 2026.

In February 2025, law enforcement shut down a 40 MW site in Ingushetia that had been operating despite the ban in effect since early 2025.

The company also faces mounting conflicts with energy suppliers over unpaid electricity bills.

Since August 1, 2025, the Faraday Group’s energy sales company lost its right to participate in electricity and capacity trading and its wholesale market participant status.

Courts are considering claims seeking 133 million rubles ($1.74 million) in penalties from En+ Sbyt and 640 million rubles ($8.37 million) from the Irkutsk Electric Grid Company for late payment under energy supply contracts.

BitRiver CEO Detained as Empire Crumbles

Amid the unfolding crisis, BitRiver founder and CEO Igor Runets was recently detained by Russian authorities and charged with multiple counts of tax evasion.

Runets was charged with three counts related to the alleged concealment of assets to evade taxes.

The court ordered Runets placed under house arrest, with his legal team given until Wednesday to appeal the ruling.

Runets and BitRiver have faced pressure in recent years.

The company was sanctioned by the US Treasury Department in mid-2022 over its ties to Russia following the invasion of Ukraine, restricting access to Western markets and partners.

In 2023, Japanese financial group SBI exited its relationship with BitRiver as it withdrew from Russia.

Despite BitRiver’s collapse, demand for mining infrastructure in Russia continues to surge.

According to the System Operator, the capacity of miners and data centers connected to the grid increased 33% in 2025, reaching 4 GW.

By 2031, the annual growth rate of the data center market in Russia could reach 14.41%, according to projections.
