MARA sold 13,597 bitcoins and repaid $750 million in debt

MARA Holdings sold 13,597 bitcoin for about $1.1 billion after September 30 and used $750 million of the proceeds to fully repay its bitcoin-backed term loan, recovering 17,477 bitcoin previously pledged as collateral. The miner also authorized up to $500 million in additional share buybacks and said it will keep selling bitcoin to fund AI infrastructure, convertible note obligations and potential repurchases. The move matters because it cuts MARA's secured debt and frees a large slice of its treasury, giving the company more balance-sheet flexibility as it pivots toward data-center and AI capacity. Watch whether MARA draws down the new buyback authorization and whether two data-center leases originally expected by year-end slip into next year, as the company flagged.
