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.
