Which public Bitcoin miner produces the most BTC?

The top public Bitcoin miners by monthly BTC production are: 1) Bitdeer Technologies Group (BTDR), 2) MARA Holdings, Inc. (MARA), 3) CleanSpark, Inc. (CLSK), 4) Riot Platforms, Inc. (RIOT), 5) IREN Limited (IREN). Rankings are updated as companies report new data on BitcoinMiningStock.io's production tracker.

How is Bitcoin production per exahash calculated?

BTC/EH/s (Bitcoin per exahash per second) is calculated by dividing a miner's monthly Bitcoin production by their operating hash rate. If a company does not report operating hash rate, installed hash rate is used instead. This metric measures mining efficiency — how much Bitcoin a company produces relative to the computational power it deploys.

BTC/EH/s stands for Bitcoin per exahash per second. It is a mining efficiency metric that shows how much Bitcoin a company produces for each exahash of computational power it operates. A higher BTC/EH/s indicates more efficient mining operations.

Bitcoin Mining Companies Ranked by Monthly BTC Production

Q: How does the Bitcoin halving affect miner production?

The Bitcoin halving reduces the block reward miners receive by 50%, directly cutting BTC production for the same amount of hash rate. After the April 2024 halving, the block reward dropped from 6.25 BTC to 3.125 BTC. Miners must either increase their hash rate or improve efficiency to maintain pre-halving production levels.

The total reported Bitcoin production is 4,724.25 as of Apr 30, 2026. By default, this page shows the latest data from each company. This page ranks the top Bitcoin miners by their monthly BTC production output, giving investors a clear view of which bitcoin mining companies are generating the most coins. Data is sourced directly from company press releases, SEC filings, and monthly production updates. Use the BTC/EH/s efficiency metric to compare how effectively each miner converts hash rate into Bitcoin, and explore historical trends to track production changes over time.

Which Bitcoin Miner Produces the Most BTC?

The current top public Bitcoin miners by monthly BTC production are Bitdeer Technologies Group (783 BTC) , MARA Holdings, Inc. (749 BTC) , CleanSpark, Inc. (640 BTC) , Riot Platforms, Inc. (491 BTC) , and IREN Limited (483 BTC) . Rankings update as companies publish new production figures through press releases and SEC filings. Use the table above to compare output across all publicly traded Bitcoin miners, and see our Bitcoin treasury holdings tracker for how much BTC each miner holds on their balance sheet.

How Does the Bitcoin Halving Affect Miner Production?

The Bitcoin halving cuts the block reward miners receive by 50%, directly reducing BTC production for the same amount of hash rate. After the April 2024 halving, the reward dropped from 6.25 BTC to 3.125 BTC per block. To maintain pre-halving production levels, miners must increase their deployed hash rate or improve operational efficiency. The YoY % column on this page shows how each miner's output has changed since the halving.

What Is a Good BTC/EH/s Efficiency Ratio?

BTC/EH/s measures how much Bitcoin a miner produces per exahash of computational power. A higher ratio indicates more efficient mining. The theoretical maximum depends on network difficulty and the block reward, so "good" is relative — compare a company's BTC/EH/s to peers in the table above. Miners with newer-generation hardware and lower-cost energy tend to achieve higher efficiency ratios.

How Public Bitcoin Miners Report Production

Bitcoin production refers to the number of Bitcoin minted by miners during a month. We only consider the numbers from direct production and exclude Bitcoin equivalent credits/revenue from power curtailment programs.

Historical BTC Production Data by Mining Company

Historical Bitcoin production data is available for each month, and users can select individual miners to access their complete production records. All key figures are plotted on charts to help you visualize output trends over time and compare performance between miners.

Percentage (%) Change Calculation Method

Most publicly traded Bitcoin mining companies disclose their Bitcoin production as a total figure, which includes coins minted for hosting services for their clients. We use this total number for percentage change calculations.

However, some miners, including Core Scientific, TeraWulf, Bitdeer, Hut 8, and Soluna, only report their mining production from self-mining operations. For these miners, the self-mining production number is used for the percentage change calculation. Notes are added where applicable.

Bitcoin per Exahash per Second Calculation Method

We calculate Bitcoin per Exahash per Second (BTC/EH/s) by taking a company's value for Bitcoin Production and dividing it by their Operating Hash Rate. For companies who do not provide their Operating Hash Rate, we substitute this with their Installed Hash Rate.
