Bitcoin Miner Sell-Offs Accelerate as MARA Cuts Debt and Riot Moves BTC

Bitcoin mining firms are converting digital asset holdings into cash as balance sheet priorities shift, with recent disclosures showing large-scale Bitcoin sales by both MARA Holdings and Riot Platforms. The transactions, disclosed through company filings and on-chain data, show a shift among major miners toward using Bitcoin reserves for debt reduction and operational funding, marking a change in capital allocation strategies.

MARA that it sold 15,133 Bitcoin between March 4 and March 25, 2026, generating approximately $1.1 billion at an average price of about $72,689 per coin. The company stated that proceeds would primarily fund the repurchase of its outstanding 0.00% convertible senior notes due 2030 and 2031.

The repurchase agreements cover approximately $367.5 million in 2030 notes for $322.9 million in cash and $633.4 million in 2031 notes for $589.9 million. The transactions closed on March 30 and March 31.

MARA estimates the transactions will capture roughly $88.1 million in value through discounted repurchases, representing about a 9% discount to par. The company added that the move will reduce outstanding convertible debt by approximately 30% and limit potential shareholder dilution associated with conversion features. Following completion, $632.5 million of 2030 notes and $291.6 million of 2031 notes will remain outstanding.

Separately, Riot Platforms has also reduced its holdings. According to data shared by Lookonchain, the company sold 500 BTC, valued at approximately $34.87 million, and transferred a total of 1,500 BTC worth about $102.3 million to NYDIG over a five-day period.

In its first-quarter 2026 operational update, Riot disclosed total Bitcoin sales of 3,778 BTC, generating $289.5 million at an average price of $76,626 per coin. As of the end of the quarter, the company held 15,680 BTC, including 5,802 BTC pledged as collateral.

The recent transactions align with a pattern among major publicly traded miners adjusting treasury strategies. MARA, which held 53,822 BTC valued at approximately $3.74 billion as of February 26, remains one of the largest corporate holders of Bitcoin.
