The group of Bitcoin miners which have stopped hashing fully to concentrate on one thing else, usually, AI, continues to obtain extra entrants.
To them, energy is now value extra AI tenants than no matter is coming from the Bitcoin Community.
Keel hits zero, Core Scientific pays to stop
The clearest signal of a full exit got here from Keel (NASDAQ: KEEL), the operator previously often called Bitfarms. It switched off its final mining websites, Panther Creek, Scrubgrass and Sharon, on June 29, after shutting Moses Lake in April, and can guide no mining income in any respect within the third quarter, in keeping with CoinShares’ Q2 2026 mining report.
This makes it the primary listed miner to succeed in zero. The price of winding down hit the miner’s gross margin, taking it to a destructive 285% for the quarter as retired rigs have been depreciated at pace. Keel additionally bought 1,085 $BTC for round $75 million at a mean of $69,100, and mentioned it plans to liquidate its remaining 1,861 cash earlier than year-end.
Others are paying to exit the market. Core Scientific (NASDAQ: CORZ) reportedly handed Block’s Proto division $41.9 million to cancel about 15 exahashes per second of next-generation 3nm mining chips. The {hardware} is reported as probably the most environment friendly ever constructed.
The gross margin from self-mining was down by 56%. The administration mentioned it runs its remaining machines solely to cowl energy contracts whereas it converts websites.
Cipher Digital (NASDAQ: CIFR), which was as soon as often called Cipher Mining, advised traders it won’t be spending on mining capex and that it expects to be out of the enterprise by the tip of 2027.
Hyperscale flips a working Michigan mine
Hyperscale Knowledge (NYSE American: GPUS) lower energy to the Bitcoin miners at its Dowagiac, Michigan facility on September 1 to prepared it for an AI colocation tenant.
The 20-megawatt take care of an unnamed California neocloud supplier is value greater than $1.2 billion over ten years, and it may go as excessive as $3 billion if the client takes an choice on one other 32 megawatts.
CEO William Horne mentioned that the transfer to close down Bitcoin mining permits the corporate to focus the location’s energy and infrastructure on the incoming buyer.
Common month-to-month hashrate fell from about 1,066 EH/s within the first quarter to 1,004 EH/s within the second and 940 EH/s within the third, a 6.3% quarterly decline and roughly 12% beneath the December 2025 peak, per Hashrate Index.
Talking on the development, Ethan Vera, COO, Luxor, mentioned, “It is a structural shift, not only a cyclical low,” whereas including that “Miners in all places are being revalued as vitality and AI infrastructure.”
The economics stopped working
In keeping with CoinShares, the weighted-average ex-tax money value to mine one Bitcoin was about $75,500 within the second quarter, whereas Bitcoin ended the interval at $58,400, lower than half its October 2025 report.
Within the fourth quarter of 2025, the mining value was round $79,995. Bitcoin was priced between $68,000 and $70,000, leaving operators down round $19,000 a coin. Greater than 15,000 $BTC have been bought by public miners since their treasuries peaked.
Whereas miners are bleeding cash on account of mining, AI cash has been flowing in to the rescue.
Greater than $70 billion has been introduced in AI and HPC contracts throughout the sector. This contains IREN’s $9.7 billion Microsoft deal, TeraWulf’s roughly $19 billion Anthropic settlement, and Core Scientific’s $14 billion-plus in anticipated contract income.
Gold advocate and long-term crypto skeptic, Peter Schiff wrote on X that AI isn’t a tailwind for Bitcoin however a rival, competing for a similar capital, electrical energy and knowledge heart house.
Why there isn’t any turning again
As soon as a website flips, it tends to remain flipped. Wolfie Zhao of The Vitality Magazine mentioned, “As soon as that multi-gigawatt energy infrastructure has been retrofitted to AI or HPC colocation, there isn’t any turning again.” Zhao added that he expects public miners to maintain winding down hashing in coming quarters.
Regulation is deepening the moat, with CoinShares reporting that there at the moment are at the very least 225 moratoriums or restrictions on data-center improvement throughout 30 states, 151 nonetheless in pressure, with New York enacting the primary statewide pause on July 14, 2026.
That shortage is priced into equities. Miners with contracted AI or HPC capability commerce at a mean of 12.9 occasions ahead gross sales, in opposition to 3.7 occasions for these with out, although greater than $100 billion of disclosed backlog is at the moment producing solely about $1.1 billion of annualized income.
Nonetheless, not each miner has given up on mining, with Bitdeer’s chief technique officer Haris Basit saying that the corporate will preserve mining alongside a 16-year Anthropic compute deal, betting on a dual-purpose mannequin through which versatile mining fills the gaps round contracted AI load.
