On September 26, according to U.S. SEC filings, Bitcoin mining company Riot Platforms (NASDAQ: RIOT) voluntarily repaid all outstanding loans to Coinbase Credit on September 21 and terminated its $200 million credit line, while also releasing the lender's claim on the collateralized Bitcoin. Riot paid the full principal and accrued interest, incurring no early termination fees or penalties, and Coinbase's subsequent lending commitments were also terminated. The credit line, revised in April 2026, carried a fixed annual interest rate of 6.15% with a maturity date extended to April 20, 2027, and Riot had previously fully drawn the amount. At this rate, the annual interest on the $200 million balance is approximately $12.3 million. As of June 30, Riot had pledged 5,821 Bitcoins as collateral, valued at about $340.7 million, which accounted for approximately 51% of its total holdings of 11,380 Bitcoins at that time; the collateral also included USDC and cash held in Coinbase Custody Trust. This credit line was initially established in April 2025 for $100 million with a variable interest rate; it was doubled to $200 million the following month with a one-time fee of $1 million. Since the window for early termination fees specified in the agreement closed on August 21, no fees were required for the repayment in September. Riot is simultaneously expanding its data center operations, having announced in August a 20-year lease agreement with an unnamed AI developer for 191 megawatts of computing power at its Rockdale facility, which is expected to generate approximately $9.1 billion in initial revenue.
