Bitcoin mining companies typically refer to companies primarily engaged in Bitcoin mining or those that once held mining as a core asset. This also includes upstream enterprises providing mining machines, mining pools, and hosting services. By 2026, the evaluation criteria for these companies had expanded from simply "how many coins mined" to include hashrate scale, electricity costs, Bitcoin reserves, data center deliveries, and AI/HPC contracts.
Publicly Traded Miners: From Mining to Energy and Compute Platforms
Marathon Digital Holdings (MARA) is often listed as one of the large publicly traded mining companies. Public disclosures in 2024 indicated that it mined approximately 12,850 Bitcoins in 2023, with revenues exceeding $380 million. As of June 2024, the company had disclosed holding over 17,000 Bitcoins, with a market capitalization of approximately $5.5 billion. At that time, it also positioned itself as a broader digital infrastructure company, acquiring Bitcoin mining data centers from Applied Digital, launching the Bitcoin sidechain and development platform Anduro, and aiming to increase hashrate to 50 EH/s by the end of 2024. These figures and plans represent the disclosed information at that time; the latest situation should be based on company disclosures.
Riot Platforms (RIOT) reported both Bitcoin mining and data center revenues in its Q1 2026 report, indicating a further shift in its business focus towards contract-based AI infrastructure. In November 2023, its market capitalization was approximately $1.64 billion, a figure based on historical market conditions.
Core Scientific (CORZ) has long been considered one of North America's largest publicly traded miners. Public reports in September 2024 stated that it was one of the largest publicly traded Bitcoin miners in the U.S. by hashrate, with plans to reach 40 to 42 EH/s by the end of 2024. By May 2026, parts of its Pecos, Texas, mining facility were reported to be repurposed for AI infrastructure. Bitmain acquired a $54 million equity stake in Core Scientific in 2023.
CleanSpark (CLSK) was still described in August 2026 as a company continuing to mine while developing AI and digital infrastructure. Market data in October 2026 showed its market capitalization at approximately $1.9 billion. The market focused on its positioning between "pure mining" and "AI optionality," but such narratives change with contracts and capacity.
Hut 8 (HUT) is a representative of companies with a faster transformation pace. In August 2026, it disclosed that its AI data center business had contracted 949 MW of IT capacity. In October 2026, its first gigawatt-scale AI data center campus was commercialized and supported by large-scale project financing. The company's narrative has shifted from a mining company to an "energy and compute platform."
TeraWulf (WULF) disclosed in August 2026 that its Lake Mariner site had 102 MW of revenue-generating critical IT capacity, with HPC leasing revenue accounting for approximately 71% of Q2 2026 revenue. In October 2026, it signed a 20-year long-term leasing agreement with Anthropic for approximately 401 MW. Public shareholding data from August 2023 listed BlackRock as one of its second-largest shareholders; the shareholder structure may have changed.
IREN (formerly Iris Energy) is branded for its renewable energy mining infrastructure, continuing mining while developing AI cloud in May 2026. Cipher Mining rebranded to Cipher Digital in February 2026, shifting towards HPC data center development. Its market capitalization in June 2024 was approximately $1.53 billion, and its Q1 2024 net income was approximately $40 million, both historical data.
Bitdeer Technologies Group (BTDR) covers self-mining, mining machine hardware, hosting, cabinet leasing, and AI cloud. In March 2026, it disclosed managing over 3.0 GW of power infrastructure. Its Q2 2026 financial report emphasized AI Cloud revenue growth and expansion in Norway and Malaysia. It also partnered with the Royal Government of Bhutan to develop hydropower facilities. In June 2024, Tether Holdings Limited held a 25% stake in the company.
Bitfarms rebranded to Keel Infrastructure and relocated to the United States in April 2026. It was initially known for its renewable energy mining farms in Quebec, Canada. Market data disclosed in October 2025 showed a significant increase in its stock price in September 2025, but stock prices change rapidly with the market.
HIVE Digital Technologies (formerly Hive Blockchain), founded in 2017, was described in September 2022 as the first publicly traded cryptocurrency mining company, operating facilities in Sweden, Iceland, and Canada.
Mining Machines and Mining Pools: Upstream Manufacturers
Bitmain, founded by Jihan Wu and Zhan Ketuan in 2013, is one of the world's leading mining machine producers and mining pool service providers. It is not just an equipment supplier but has also entered into partnerships with mining companies through equity investments, such as acquiring an equity stake in Core Scientific in 2023.
Canaan Creative, also a Chinese mining machine manufacturer founded in 2013, is well-known in the industry for its Avalon brand. In December 2020, its market capitalization was approximately $590 million, and it had collaborated with chip manufacturing and foundry systems. These are earlier public records, and its business structure may have been adjusted subsequently.
What to Note When Reviewing
The list of mining companies is not a static ranking. Hashrate, power contracts, Bitcoin holdings, AI/HPC orders, mergers, rebrandings, and stock prices all change the meaning of "well-known." Readers checking relevant company stock prices, market capitalization, and announcements can view the latest information on market data platforms like Svmuu, and then combine it with financial reports and regulatory filings for judgment.
In terms of industry trends, by 2026, mining company valuations are increasingly tied to energized hashrate, electricity costs, Bitcoin reserve strategies, and data center delivery capabilities. Halving events typically affect the supply growth rate, but whether market share is concentrated depends on capital, energy, and operational capabilities, and cannot be simply predicted by a single metric.
Risks are also concentrated: rising electricity costs, equipment depreciation, financing pressure, technological iteration, regulatory changes, and AI transformation execution falling short of expectations can all alter a mining company's operating results.
