Two of the world’s largest Bitcoin miners, MARA Holdings and Hut 8, reported significant profit growth and expansion of Bitcoin reserves for the third quarter of 2025. At the same time, both companies are diversifying their businesses toward computing and energy infrastructure for artificial intelligence.
Bitcoin miners confirm the strength of the market
MARA Holdings increased its revenue by 92% year-on-year to $252 million and moved from a loss of $125 million to a profit of $123 million. Hut 8 reported similarly strong performance, with revenue nearly doubling to $83.5 million and profit of $50.6 million. Both companies have thus demonstrated that Bitcoin mining can be highly profitable even in the dynamic environment of cryptocurrencies.
Expansion of Bitcoin reserves: MARA Holdings ended the quarter with 52,850 Bitcoins, nearly double the 26,747 BTC it had a year ago. Hut 8 increased its reserves to 13,696 BTC from 9,106 BTC last year. The strengthening of reserves confirms both companies’ strategic emphasis on holding digital assets as long-term value.
Bitcoin mining is changing
Mining companies are increasingly positioning themselves as providers of computing and energy infrastructure. MARA is investing in low-carbon data centers for artificial intelligence through the $168 million acquisition of French company Exaion. Hut 8 currently manages 1.02 gigawatts of capacity and plans to expand to more than 2.5 gigawatts to support not only Bitcoin mining but also AI projects.
Market reaction and conclusions: Despite strong results, both companies’ shares fell; Hut 8 lost approximately 9% and MARA Holdings 5%. Despite short-term fluctuations in the stock markets, the strategies of both companies suggest that the future of Bitcoin mining will be increasingly linked to sustainable infrastructure and the development of artificial intelligence.
