Bitdeer hits 70 EH/s in self-mining bitcoin operations, claims top spot by compute

Bitdeer (NASDAQ: BTDR) produced 661 self-mined bitcoins in March 2026, up 480% from the same month last year, according to its latest operations update. The firm has been ramping up its bitcoin mining business to become a dominant player in the ecosystem.

According to its filing on Wednesday, Bitdeer now commands about 225,000 self-owned rigs, out of the 262,000 it has under management. It is also scaling up to 3.0 gigawatts in global energy capacity, including the operations in the pipeline.

In total, Bitdeer said its self-mining bitcoin operations scaled to about 70 exahashes per second (EH/s), an 504% increase year over year, once again making it the largest miner by computer power. This is a title Bitdeer claimed at the end of last year, when it reported “total hash rate under management” of 71 EH/s, including, at the time, a self-mining hashrate of 55.2 EH/s.

MARA, the next-largest miner, reports a hashrate of 66.4 EH/s on its website. Cleanspark, another major player which also reported data on Wednesday, claims an average operating hashrate of 47.3 EH/s.

Bitdeer’s total hashrate under management also grew to 78.1 EH/s, including its self-mined fleet and hosted machines, as of the end of March.

The total global hashrate stands at about 855 EH/s, according to The Block’s data. This is down slightly from the start of the year, though it remains elevated compared to the historical measurement.

The Bitcoin global hashrate in Q1 2026 saw the largest intra-quarter decline in about five years amid relatively depressed prices and increased competition, even as firms continue to redirect resources toward the AI computing sector.

Bitdeer also noted its AI activity continues to scale. The firm said its AI Cloud utilization rose to 94%, up from 64% last month, while its AI Cloud annual run rate reached about $43 million, up 105% month-over-month. 

“This momentum underscores both the scale of the market opportunity and our ability to execute effectively in delivering high-performance AI infrastructure,” said Matt Kong, Chief Business Officer of Bitdeer.

The firm also continues to roll out new mining machines, including its state-of-the-art SEALMINER A4 series that reports efficiencies of ~9.45 J/T. The firm is “in final assembly” of introducing A4s to its self-mining fleet. Last month, Bitdeer also launched its SEALMINER DL1 Air series, purpose-built for the Scrypt algorithm used by proof-of-work chains like Litecoin and Dogecoin.

CleanSpark and Canaan growth 

Meanwhile, CleanSpark (Nasdaq: CLSK) reported on Wednesday that it had mined 658 bitcoins in March, bumping its year-to-date figure to 1,799 BTC produced. 

Its operational hashrate at the end of March came in at about 50 EH/s, with its 224,473 mining machines recording a peak fleet efficiency of 16.07 J/Th. This represents an 11% increase in average monthly hashrate, the quarterly filing noted.

The company also reported controlling a portfolio of more than 1.8 GW of power, land, and data centers in the U.S., of which 808 MW is utilized.

CleanSpark CEO Matt Schultz noted the firm is also working to expand beyond bitcoin mining, and is making “significant headway toward securing our first hyperscale customer in AI and high-performance computing.”

Canaan (NASDAQ: CAN), meanwhile, produced 89 BTC in March as its crypto holdings hit a record high of 1,808 BTC and 3,952 ETH at month-end. 

The firm posted a deployed hashrate of 10.97 EH/s, not including an additional 4.4 EH/s via a joint venture acquired from Cipher Mining. In February, Canaan purchased Cipher’s 49% equity interest in three West Texas facilities.

“Against the backdrop that Bitcoin’s average network hashrate experienced the largest quarterly decline since 2021, we continued to grow our deployed hashrate and installed power capacity, adding over 10 MW to our network during the month,” Canaan CEO Nangeng Zhang said. 

Canaan’s global installed power capacity hit 266.3 MW, plus an additional 120 MW from its West Texas joint ventures.
