MARA Clears $750M BTC-Backed Debt, Approves $500M Buyback After Q3 Profit

MARA's decision to retire its bitcoin-backed debt rather than keep the leverage in place signals a shift in how a large miner is managing its balance sheet, trading collateral risk for flexibility just as the buyback authorization adds a capital-return lever miners have rarely used. The move matters most for peers weighed down by similar BTC-collateralized facilities, since MARA's profitable quarter is what made the deleveraging affordable. Whether the buyback is actually executed, and whether other miners follow the same de-risking path, is the open question.
