MARA sells 13,597 BTC to fund AI data centers and repay debt

What happened

In the six weeks following the end of September, Marathon Digital Holdings (MARA) sold 13,597 Bitcoin, raising approximately $1.1 billion. The average price of the coins was about $81,039, which translates to roughly 40% of the 34,012 BTC the company reported at the close of September. The volume sold is also six times the amount the miner produced during the third quarter.

The bulk of the cash, $750 million, was applied to repay Bitcoin‑collateralized loans, unlocking 17,477 BTC that had been pledged as security. This repayment cut the share of Bitcoin that was pledged or lent from roughly 57% to under 5% of the remaining holdings. The balance of the proceeds is slated for building artificial‑intelligence data‑center capacity, covering additional debt obligations, and potentially funding share‑repurchase programs authorized for up to $500 million.

Why it matters

MARA's decision marks a clear departure from its earlier policy of holding virtually all mined coins. By converting a sizable portion of its reserve into cash, the company reduces its exposure to Bitcoin price volatility while simultaneously injecting liquidity into a fast‑growing AI infrastructure market. The move also adds a notable source of supply to a Bitcoin market that has been struggling for buyers, influencing price dynamics and setting a precedent for other publicly traded miners.

Background

Marathon Digital is one of the largest publicly listed Bitcoin miners in the United States. Historically, the firm financed operations by borrowing against its Bitcoin holdings, a strategy that helped fund the acquisition of the Long Ridge natural‑gas power business, a 485 MW asset intended to support future data‑center projects. In the third quarter, revenue fell 35% year‑over‑year to $164 million, while reported profit of $632 million was driven largely by accounting gains linked to digital assets rather than recurring mining cash flow.

What to watch

Investors should monitor several developments: the completion of the Long Ridge acquisition and the signing of data‑center lease agreements, which will determine how effectively the newly raised capital is deployed; the pace of any further Bitcoin sales, which could add pressure to an already fragile market; and Bitcoin's price trajectory, especially whether it can regain key moving‑average support levels. Additionally, any activation of the $500 million share‑repurchase authorization could further affect the company's capital structure.
