The economics of MARA’s Bitcoin accumulation strategy

Scale of the massive treasury

MARA holds over 50,000 bitcoin. This treasury exceeds the combined holdings of the five next largest public miners. In 2024, the company purchased 22,065 bitcoin and mined 9,500 coins. This "twin turbo" strategy combines mining with aggressive open market buys. The value of 50,000 bitcoin reaches approximately $5.45 billion. If converted to cash, these bills would occupy 217,000 cubic feet and cover 22 square miles. This amount could finance the construction of the Burj Khalifa more than three times over. This sum could also build four Jeddah Towers, each costing $1.2 billion.

The scale is massive.

In 2024, MARA’s holdings grew from 15,000 bitcoin to 44,893 bitcoin by December 31. The company accounts for around 5% of the Bitcoin network hashashrate. Bitcoin costs vary. Such a stockpile would take most miners over a decade to accumulate through mining alone. This amount could buy a $15 pizza for every person in the United States.

Financing the growth engine

The company uses convertible notes to scale its holdings. In 2024, MARA raised $2 billion through such offerings. In July 2025, the company closed an upsized $950 million offering of 0.00% convertible senior notes due 2032. These notes provide $940.5 million in net proceeds. MARA used $36.9 million of those proceeds to pay for capped call transactions. The 2030 notes bear interest payable semi-annually on March 1 and September 1.

MARA faces high costs.

The firm reports the largest operational losses among its peers because fixed mining costs and volatile production revenues create constant pressure. The company manages 1.7 gigawatts of capacity across 15 data centers. It owns 139 megawatts of wind and gas-to-power assets. This vertical integration helped decrease the cost per petahash by 17% in 2024. In March 2025, MARA sold 15,133 bitcoin for $1.1 billion to reduce debt. This sale lowered outstanding convertible debt from $3.3 billion to $2.3 billion.

Valuation and Bitcoin leverage

Investors buy MARA for Bitcoin exposure. The company’s market cap stays close to its Bitcoin holdings. In late 2024, the company’s market cap of $5.7 billion sat just above the $4.2 billion market value of its 44,893 bitcoin holdings, which makes the stock a leveraged play on Bitcoin price movements. If Bitcoin prices drop, the debt becomes a larger portion of the firm’s total value. This leverage cuts both ways.

The company manages its Bitcoin actively. It lent 7,377 bitcoin to earn yield at the end of 2024. It also invested treasury assets with a digital asset manager. This strategy differs from MicroStrategy, which holds over 582,000 bitcoin and trades at 1.65 times its crypto holdings value. You know how mining costs scale with hashrate.

Does the mining business justify such heavy debt?
