Igor Runets, founder of Russian Bitcoin mining firm BitRiver, faces a bankruptcy petition filed by PSB Bank over overdue loan guarantees totaling approximately $9.27 million (773 million rubles). The petition was submitted to the Sverdlovsk Oblast Arbitration Court, with PSB Vice Chairman Mikhail Dorofeev stating that Runets bears joint liability as guarantor for a loan to subsidiary "Bitriver-B," which has defaulted on its obligations. Runets was placed under house arrest in early February 2026 on charges of concealing large sums owed in taxes, fees, and insurance premiums. In recent months, multiple BitRiver entities have appeared in courts as both plaintiffs and defendants, with some subsidiaries entering observation proceedings.
