Bitcoin miners aren't just chasing coins now. The companies with cheap power and finished data halls are being repriced as AI infrastructure landlords.
The clearest signal in Bitcoin mining is no longer how many machines a company plugs in. It's who gets the electricity. Public miners spent the last cycle telling investors they could turn power into Bitcoin at scale. Now Core Scientific, TeraWulf, Bitdeer, Hut 8, IREN, you name it, are showing a more profitable use for the same sites: lease them to AI and high-performance computing customers that need power yesterday.
This is a hard pivot, not a side project. Core Scientific's second-quarter results, released on July 28, put colocation revenue at $136.7 million against $21.5 million from digital asset self-mining. That's the business in one line. The company also said its AMD partnership could support up to 2.5 gigawatts of leasable capacity, with 15-year agreements covering about 530 megawatts across five sites and more than $14 billion of potential base contracted revenue.
Money explains the move. It usually does.
CoinDesk reported in March that CoinShares' Q1 2026 mining report put the weighted average cash cost to produce one Bitcoin for listed miners at about $79,995 in the fourth quarter of 2025, while Bitcoin was trading near $68,000 to $70,000. CoinDesk put the loss at roughly $19,000 per coin mined. Mine a coin, lose money on the coin. Lease the same power to an AI customer with a long contract, and the boardroom conversation changes fast.
The Power Is The Product #
The old miner pitch was hashrate. The new pitch is megawatts. If you own a powered campus, a grid connection, cooling plans, and buildings that can be converted, you own something rare. AI companies cannot build that quickly. That is why the mining sector has become interesting to a different class of buyer and investor.
CoinDesk reported that more than $70 billion in AI and HPC contracts had been announced across the public mining sector by late March. The same report cited CoreWeave's expanded Core Scientific deal, TeraWulf's contracted HPC revenue, Hut 8's AI lease at River Bend, and Cipher Digital's agreement with Google-backed Fluidstack. Those details are not noise. They show the market is paying for power access, not for ideological purity about Bitcoin.
TeraWulf's own filings make the change plain. In its first-quarter 2026 report, the company recorded $21.0 million in HPC lease revenue and $13.0 million from mining. It also said two miner buildings were repurposed or placed out of service to support HPC development at Lake Mariner. Then, on July 6, TeraWulf disclosed a 20-year lease with Anthropic for about 401 megawatts of critical IT load at its Justified Data Campus in Hawesville, Kentucky. That's not dabbling. That's a company choosing the tenant over the token.
You should be clear about what this means. Bitcoin mining is still there, but for some public miners it is no longer the center of gravity. The scarce asset is the power contract. The customer just changed.
Bitdeer Is Taking The Other Route #
Bitdeer is the useful exception because it shows this shift is not one simple industry retreat. The company is still leaning into mining. In its first-quarter 2026 results, Bitdeer reported $146.9 million of self-mining revenue and said adjusted EBITDA improved year over year, driven partly by higher self-mining hashrate from SEALMINER deployment. That is a different bet from winding down rigs to free up every available megawatt for AI.
But even Bitdeer is not ignoring the AI money. On March 30, the company said its Tydal Data Center in Norway was being converted into an AI data center designed around Nvidia's Vera Rubin technology, with 180 megawatts of gross installed capacity targeted for completion as early as December 2026. On June 29, Bitdeer said its Tydal subsidiary had executed a colocation lease agreement, while warning that the lease had not yet become effective and still depended on conditions outside its control.
That caveat matters. Keep it in. A signed lease that has not become effective is not the same thing as cash in the bank, and anyone writing about these miners has to resist treating every announced AI deal as finished revenue. The sector has moved from Bitcoin price risk into execution risk: construction, financing, customer timing, grid approvals, and whether AI demand keeps absorbing capacity at today's pace.
Still, the direction is obvious. Public miners once sold investors a clean story about securing the Bitcoin network and stacking coins. Now the strongest companies are selling something more ordinary and more valuable: buildings, power, cooling, and long leases. Frankly, that may be the better business.
Bitcoin can recover and make mining margins look better again. It probably has to, if pure-play miners want the old model to work. But the AI deals have already changed how these companies think about their sites. Once a miner learns that a megawatt can be rented to an AI tenant instead of pointed at SHA-256, hashrate stops being destiny.
