What are bitcoin mining stocks?

Bitcoin mining stocks are shares in publicly traded companies whose main business is mining bitcoin. Owning one is owning part of a company, with its own costs, debt and strategy, not owning bitcoin itself. This guide explains how these companies earn money and how they differ from the coin; it is not investment advice.

How do bitcoin mining stocks work?

A mining company runs large fleets of specialised machines that compete to add blocks to the bitcoin network (see how bitcoin mining works). In its annual report for 2025, MARA Holdings explains that it earns the block reward, currently 3.125 BTC, plus transaction fees for blocks it wins, and that it takes part in mining pools.

The same filing lists the main pressures. The cost to mine does not move with bitcoin's price, so a falling price squeezes cash flow. The April 2024 halving cut the reward in half, and MARA expects the next one around April 2028. Difficulty adjusts roughly every two weeks, so a miner's share shrinks unless it adds computing power as fast as rivals. Power prices and curtailment also matter.

Which companies are on a bitcoin mining stocks list?

Commonly cited US-listed miners include MARA Holdings, Riot Platforms, Core Scientific, IREN, Cipher, TeraWulf, Hut 8 and Bitdeer, all named in coverage by The Block. Any list like this is only a set of examples. It is not a ranking or a suggestion to buy anything, and companies change their business mix often.

What are AI bitcoin mining stocks?

Miners already control power connections and large sites, which AI companies need. In June 2024 Core Scientific signed 12-year contracts to host GPUs for CoreWeave, and The Block reported that a JPMorgan note saw this as accelerating the move into HPC. In January 2025 Riot paused a planned 600 MW mining expansion at its Corsicana, Texas, site to keep that power for possible AI and HPC uses.

S&P Global reported in February 2026 that weak crypto prices and high energy costs were pushing more miners in this direction. CoinShares' first-quarter 2026 report, covered by The Block, counted more than 70 billion dollars in announced AI and HPC contracts across the sector and said AI could reach up to 70% of listed miners' revenue by the end of 2026. It also flagged heavy debt taken on to fund these buildouts.

How do bitcoin mining stocks compare with bitcoin?

Bitcoin is a single asset with a fixed supply schedule. A mining stock adds company factors on top: operating costs, borrowing, share issuance, management decisions and, increasingly, a separate data center business. Some miners also hold bitcoin on their balance sheet, which links them to the coin in another way, similar to a crypto treasury company.

CoinShares noted that several listed miners sold part of their bitcoin holdings in early 2026 during a period of tight margins. For a different way to get exposure without holding coins directly, see bitcoin ETF vs owning bitcoin.
