In One Year, Publicly Listed U.S. Crypto Miners Have Increased Bitcoin Holdings to Close to 100K.

Publicly traded U.S. crypto mining companies have seen significant growth in their bitcoin holdings over the past year. According to data from TheMiningMag, these companies now hold a combined total of 92,473 BTC, valued at approximately $8.6 billion as of December 2024, marking an impressive 120% increase in the price of bitcoin.

MARA Holdings (MARA) holds the largest share, with 44,893 BTC, making it the second-largest holder among publicly listed companies, following MicroStrategy (MSTR), which holds 450,000 BTC. This strategy of long-term bitcoin accumulation, known as “HODLing,” has gained popularity, and several other miners are also following suit.

Riot Platforms (RIOT) holds 17,722 BTC, while Hut 8 (HUT) and CleanSpark (CLSK) hold 10,171 BTC and 10,097 BTC, respectively. Together, these companies contribute significantly to the growing trend of HODLing.

Not all miners, however, subscribe to this approach. Companies like IREN (IREN), TeraWulf (WULF), and Core Scientific (CORZ) have maintained minimal or no bitcoin holdings, pivoting instead to sectors like artificial intelligence (AI) and high-performance computing (HPC) to stay competitive.

While bitcoin’s performance has outpaced that of many mining stocks, standout companies like Core Scientific and TeraWulf, which have embraced AI, saw returns of over 300% in 2024.

In 2025, miners who have chosen to hold onto their bitcoin have benefitted strongly. Riot, Hut 8, and CleanSpark have outperformed bitcoin itself, while Bitdeer (BTDR) experienced a slight decline after a strong 2024.
