MARA Holdings (NASDAQ: MARA) has taken a significant step in leveraging its substantial Bitcoin reserves by committing 18,750 BTC as collateral for newly arranged credit facilities. This move, detailed in the company’s recent quarterly SEC filing, secures substantial incremental capital aimed at advancing its strategic shift toward energy generation and artificial intelligence infrastructure.
On August 4, 2026, the firm finalized two Bitcoin-backed term loan arrangements providing $600 million in additional borrowings.
One facility, arranged with Coinbase Credit, consolidates and refinances a prior $150 million credit line while delivering $300 million of fresh capital.
The second, from Two Prime Lending, contributes another $300 million.
Together these create a combined principal of $750 million that has been fully drawn.
Both facilities carry maturities in early August 2028, with the Coinbase arrangement including a potential one-year automatic extension unless either party opts out.Interest terms differ between the lenders.
The Coinbase facility uses a floating rate based on the midpoint of the Federal Reserve’s target range for federal funds plus 3.875 percent.
The Two Prime facility carries a fixed rate of 7.65 percent. Weighted average costs for the new borrowings were reported around 7.56 percent.
At prevailing rates, annual interest expense on the combined facilities would approximate $56.7 million if principal levels remain steady.
The 18,750 BTC pledged as initial collateral carried a fair value of roughly $1.2 billion at closing.
This amount represents a substantial portion of the company’s treasury.
As of June 30, 2026, MARA reported total holdings of 35,577 BTC, of which approximately 9,270 were already loaned or pledged under earlier arrangements.
The new collateral commitment therefore activates a large share of remaining reserves for financing purposes.
Lenders require maintenance of specified collateral ratios; a decline in Bitcoin’s market price could trigger margin calls requiring additional pledges. Failure to meet such requirements would permit liquidation of the collateralized coins.
Proceeds are earmarked for general corporate purposes, with particular emphasis on funding a portion of the cash consideration for the pending acquisition of Long Ridge Energy & Power LLC.
That transaction, announced earlier in 2026, carries an enterprise value of approximately $1.5 billion.
Long Ridge owns a highly efficient combined-cycle natural gas power plant in Hannibal, Ohio, with nameplate capacity expected to reach 505 megawatts, along with more than 1,600 acres of industrially permitted land.
MARA intends to develop the site for expanded power generation, continued Bitcoin mining, and potential campuses dedicated to AI and high-performance computing.
The location already hosts some of the company’s existing data center capacity and offers access to water, fiber, and grid infrastructure.
This financing approach allows MARA to access non-dilutive capital while retaining upside exposure on its remaining Bitcoin holdings rather than selling additional coins or issuing equity.
It aligns with the company’s evolving strategy of treating its digital asset treasury as both a long-term reserve and a flexible funding tool for growth initiatives beyond pure mining operations.
The Long Ridge deal remains subject to customary closing conditions, including regulatory approvals, and is targeted for completion later in 2026.
By committing a sizable portion of its Bitcoin holdings in this manner, MARA demonstrates confidence in both the collateral asset and its broader infrastructure ambitions. The arrangement underscores how leading Bitcoin miners are increasingly integrating traditional energy assets with compute-intensive opportunities in AI and high-performance computing.
