Mara Holdings, owner of the second-largest BTC treasury, has reached the milestone of 50,000 BTC. The mining company relies on its growing hash rate to boost its reserves.
Mara Holdings announced the expansion of its treasury to 50,000 BTC. Unlike other treasury companies, Mara combines mining operations with strategic purchases. The company plans to expand its mining capacity to 75 EH/s by the end of the year.
"50,000 BTC now sits in Mara’s treasury.
Powered by 57+ EH/s of computational strength, reinforcing our nation’s digital economy and energy infrastructure.
This is Mara in action for America.
Next goal: 75 EH/s by year-end."— Mara (@mara) July 3, 2025
How Mara Holdings Built Its BTC Treasury
Mara Holdings began deliberate BTC acquisitions in late 2024, starting with 27,000 BTC. Since then, the company has steadily grown its holdings through mining operations. While the exact acquisition cost remains undisclosed, Mara likely benefits from lower mining costs compared to market purchases.
The company also unveiled a $2B plan for additional BTC purchases, though stock sales will be executed at Mara’s discretion. So far, the miner has prioritized organic growth over aggressive acquisitions.
Mara Holdings Tripled Its Treasury in 12 Months
Over the past year, Mara Holdings nearly tripled its BTC holdings, though it lacks a formal strategy like MicroStrategy (MSTR). The Mara.com pool currently produces 7% of all blocks, backed by 45 EH/s of active mining power.
Following a record mining month in May, Mara expanded its treasury further, adding 761 BTC in June without selling newly mined coins. The company’s latest semi-annual report highlights strong retention of mined BTC despite temporary slowdowns due to heatwaves.
