MARA sold 15,133 BTC to cut debt and fund AI buildout

MARA Holdings sold 15,133 BTC between March 4 and March 25, 2026, raising roughly $1.1 billion at an average price of about $72,700 per coin, according to the miner’s reported transaction figures. Most proceeds retired convertible debt; the company is also redirecting infrastructure capital toward AI data centers.

The sale broke with MARA’s long-standing treasury posture, summarized as “buy, mine, never let go.” The new approach allows periodic Bitcoin sales as a capital-management tool, turning part of a non-interest-bearing treasury into cash for debt reduction and expansion.

What changed in MARA’s Bitcoin holdings?

MARA held 53,822 BTC at the end of February 2026. Immediately after the March sale, holdings fell to approximately 38,689 BTC. By June 30, the company reported holdings of about 35,577 BTC.

It disclosed first-half sales totaling 23,093 BTC, generating approximately $1.6 billion at an average price of roughly $70,631 per coin. Bitcoin dipped below $69,000 around the sale announcement, a few thousand dollars beneath MARA’s average price during the March window.

MARA remains a significant corporate Bitcoin holder. However, it has slipped behind competitors such as Twenty One Capital as competition among corporate treasury companies intensified.

How did the note buyback reduce leverage?

The bulk of the March proceeds funded the repurchase of about $1 billion of convertible senior notes due in 2030 and 2031. MARA completed the transactions privately at an approximate 9% discount to par.

That discount generated an estimated $88 million in value. The repurchase also reduced MARA’s convertible debt load by around 30%, giving the company more balance-sheet capacity ahead of its computing buildout.

Why is MARA targeting AI computing?

MARA’s destination is digital energy and AI high-performance computing data centers. HPC refers to dense, power-hungry server installations used to train and operate AI models. Mining farms already have the land, cooling systems and grid connections those servers require.

The company partnered with Starwood Capital Group on a project targeting nearly 1 GW of near-term computing capacity. The partnership could expand beyond 2.5 GW, although MARA has not provided a commissioning schedule for that larger figure.

MARA also acquired the Long Ridge Energy natural gas plant in Ohio to support the transition. Owning generation gives the company greater control over its electricity supply and reduces its need to compete for power from the grid.

The strategy responds to compressed mining economics following Bitcoin’s most recent halving. Each halving cuts the reward per block in half, leaving miners with fewer coins for the same electricity bill. Unless Bitcoin’s price rises enough to offset that reduction, profits narrow.

Miners already hold power contracts, buildings and cooling systems, alongside Bitcoin that pays no interest. Selling coins to retire debt and finance AI construction turns those assets into infrastructure that could generate recurring revenue.

What changes for shareholders and Bitcoin supply?

The immediate market-structure change is supply. MARA’s willingness to become a periodic seller adds corporate-held Bitcoin that buyers must absorb, extending the pool of large treasury companies willing to distribute coins.

For MARA shareholders, the debt retirement provides measurable benefits. The 9% discount captured an estimated $88 million, while leverage fell by roughly 30%. The offset is execution risk: MARA is trading a known Bitcoin holding for an infrastructure program dependent on delivering planned capacity.

Three operating and financial measures will determine whether that shift creates durable value:

• How much of the nearly 1 GW Starwood-backed capacity comes online, including progress toward possible expansion beyond 2.5 GW.
• Whether MARA continues selling Bitcoin after disclosing first-half disposals of 23,093 BTC.
• How reported holdings move from the approximately 35,577 BTC recorded on June 30, 2026.

The next checkpoints are Starwood-backed capacity coming online and whether further Bitcoin sales reduce holdings below MARA’s June 30 level.
