Russian authorities have escalated legal proceedings against Igor Runets, founder and CEO of BitRiver, one of Russia's largest industrial Bitcoin mining data centre operators. The case transforms a commercial contract dispute into a criminal matter, though the published evidence has not yet established deliberate deception.

The Equipment Contract Dispute

According to court details reported by Kommersant, Infrastructure of Siberia, a subsidiary of energy and metals conglomerate En+ — one of Russia's largest aluminum and hydropower producers — prepaid Fox Group for mining equipment that the company says was never delivered. Infrastructure of Siberia subsequently terminated the agreement and demanded reimbursement of the advance payment plus penalties.

In April 2025, an arbitration court awarded the En+ affiliate 954.4 million rubles (approximately $11.9 million), covering both the advance and delay penalties. Runets told Kommersant at the time that the equipment had in fact been supplied and that Fox Group intended to appeal the ruling.

Criminal Proceedings and Pre-Trial Detention

Runets was already under legal restrictions before the fraud case emerged. On January 31, the Zamoskvoretsky District Court placed him under house arrest for two months over allegations that he concealed money or property from tax collection, according to an official Moscow courts announcement.

The fraud case is legally distinct from the tax concealment allegations. Under Russian law, tax concealment involves assets that should have been available to tax collectors, while fraud requires demonstrating deception or abuse of trust in obtaining property or rights. Investigators reportedly sought stricter pre-trial measures partly on grounds that Runets could influence witnesses at companies under his control.

The fraud charges fall under Article 159, Part 4 of the Russian Criminal Code, which covers aggravated circumstances including offenses committed by an organized group or on an especially large scale. This classification carries penalties of up to 10 years' imprisonment along with possible fines and restrictions on liberty. Investigators have not publicly disclosed which specific representations they consider deceptive, which entity they identify as the victim, whether the alleged damages correspond to the 954.4 million-ruble arbitration judgment, or how they connect Runets personally to the disputed transactions.

Fox Group Bankruptcy Proceedings

A separate civil track has been running concurrently. On January 27, the Arbitration Court of the Sverdlovsk Region opened observation proceedings against Fox Group, which controls 98% of BitRiver's management company. The proceedings were initiated after Infrastructure of Siberia filed for Fox Group's bankruptcy. Kommersant reported that the recognized creditor claim exceeded 700 million rubles including penalties, with the creditor stating that enforcement efforts had failed to locate sufficient Fox Group assets.

Observation is the initial stage of Russian insolvency proceedings, during which a court-appointed administrator reviews the company's finances and creditor claims before the court determines further action. The process remains considerably distant from liquidation.

The civil and criminal proceedings address fundamentally different questions. Bankruptcy asks whether Fox Group can pay its debts, while fraud asks whether anyone lied to obtain the money in the first place. A company can fail comprehensively without any crime having been committed, which is why the arbitration judgment cannot substitute for a criminal finding.

Implications for BitRiver

BitRiver grew into one of Russia's largest operators of industrial Bitcoin mining data centres, with Runets central to the company's relationships with power suppliers, equipment vendors, customers, and regional authorities. The company benefited from Siberia's abundant hydropower and comparatively low electricity costs, factors that had made Russia one of the world's significant Bitcoin mining jurisdictions by hash rate, particularly after China's 2021 mining crackdown displaced operations that had previously dominated global production. Removing a founder from day-to-day control while creditors pursue claims creates both a governance challenge and a financial one.

The company was already operating under external constraints. In April 2022, the U.S. Treasury sanctioned BitRiver AG and 10 Russia-based subsidiaries, marking the first designation of a virtual currency mining company. The sanctions cut BitRiver's access to international partners and financial infrastructure years before the current domestic legal issues emerged.

Within Russia, the regulatory environment has tightened in a different direction. In August 2024, Russia enacted legislation formally legalizing and regulating cryptocurrency mining, establishing a licensing framework and a miner registry administered by the Federal Tax Service. More than 5,500 crypto miners have entered the official registry, and large operators now operate under substantially greater scrutiny regarding revenue, power consumption, and corporate structure. Several Siberian regions have additionally moved to restrict mining activity during winter peak demand periods, placing further pressure on industrial-scale operators whose business models depend on continuous low-cost power access.

What Remains Unresolved

The documented public record covers an equipment dispute, an arbitration judgment approaching 1 billion rubles, and an insolvency procedure against BitRiver's controlling shareholder. The criminal narrative connecting these facts to deliberate deception has not been published. Several developments could resolve the ambiguity: a formal statement from BitRiver or an acting executive, new court orders naming its operating subsidiaries, confirmed operational interruptions at individual mining sites, asset sales ordered through the insolvency process, or a detailed criminal filing identifying specific BitRiver entities.

Until then, the case exists between two interpretations. One reading suggests a mining business that overextended, failed to deliver on a contract, and collapsed under pressure from creditors. The other suggests fraud. The evidence published so far supports the first interpretation and does not yet establish the second.

Disclaimer: Igor Runets has not been convicted of any offense, and the allegations described here remain unproven. Detention under Russian criminal procedure is a pre-trial measure rather than a finding of guilt. Nothing in this article establishes wrongdoing by BitRiver or its subsidiaries.
