Marathon Digital Holdings (NASDAQ: MARA), one of the world’s leading Bitcoin mining firms, has bolstered its cryptocurrency holdings by acquiring an additional 400 BTC, valued at approximately $46.31 million.
The purchase was executed via institutional trading platform FalconX, according to blockchain analytics firm Lookonchain.
With this acquisition, Marathon now holds 52,850 BTC, worth an estimated $6.12 billion at current market prices, solidifying its position as the second-largest public corporate holder of Bitcoin.
The top spot remains with MicroStrategy, which holds 640,031 BTC valued at roughly $77 billion.
Despite recent volatility in its share price, Marathon appears undeterred in its aggressive Bitcoin accumulation strategy.
On October 10, MARA stock closed at $18.64, down 7.75% for the day. However, it bounced back in after-hours trading, rising 2.66% to $19.13.
Marathon’s proactive approach to Bitcoin investment comes on the heels of strong financial performance.
The company reported $238 million in revenue for Q2 2025, a 64% increase year-over-year, beating Wall Street expectations. Its Bitcoin holdings reached 49,951 BTC by the end of June, up 170% from the previous year.
Beyond mining and Bitcoin treasury strategies, Marathon is expanding into broader technology sectors. The company recently partnered with Google-backed TAE Power Solutions and LG-backed PADO AI to co-develop energy-efficient platforms designed for AI and next-generation data centers.
CEO Fred Thiel emphasized Marathon’s commitment to becoming a vertically integrated tech and energy firm, stating, “Our vertically integrated mining operations, large BTC treasury, budding international energy partnerships, and early AI infrastructure investments each contribute distinct and measurable value.”
Marathon aims to scale its mining capacity to 75 exahashes per second (EH/s) by the end of 2025, reinforcing its commitment to long-term growth and innovation in the digital asset space.
