It just occurred to me that Bitcoin miners are currently going through a fundamental realignment, and this shows up most clearly in their balance sheets, not in the hash rate figures.

The situation is actually pretty brutal: publicly traded miners are producing Bitcoin with costs of about $80,000 per coin, while BTC is trading around $72,000. That means massive losses per block—we’re talking about roughly $19,000 in the red per mined Bitcoin. These figures simply can’t be sustained, and the miners know it.

The answer? A complete pivot to AI infrastructure. This is no longer a side business—that is now the main strategy. According to current reports, publicly traded miners have announced more than $70 billion in AI and high-performance computing contracts. Core Scientific has a $10.2 billion deal with CoreWeave, TeraWulf sits on $12.8 billion in HPC revenue, Hut 8 has a $7 billion deal for 15 years. These are not small amounts.

What’s interesting is that these miners could generate 70 percent of their revenue from AI as early as the end of 2026, compared with about 30 percent today. Core Scientific already accounts for 39 percent of its revenue from AI colocation. That means these companies are effectively turning into data center providers that also mine Bitcoin—rather than the other way around.

The economics are actually straightforward: Bitcoin mining hardware costs about $700,000 to $1 million per megawatt, while AI infrastructure costs $8 million to $15 million per megawatt. But here’s the catch—AI structurally offers much higher and more stable margins, at over 85 percent, with multi-year revenue visibility. In contrast, the hash price for miners has fallen to historic lows.

How are miners financing this transition? In two ways: massive borrowing and Bitcoin sales. IREN now has $3.7 billion in convertible bonds, and TeraWulf has $5.7 billion overall. Cipher Digital has increased interest expenses from $3.2 to $33.4 million in Q4. These are no longer mining debts—that’s infrastructure-scale bets.

On the other hand, miners are selling their Bitcoin holdings. Core Scientific liquidated 1,900 BTC in January for $175 million and plans to sell the rest in the first quarter. Bitdeer reduced to zero, Riot Platforms sold 1,818 BTC, and even Marathon—the largest publicly listed Bitcoin holder with over 53,000 BTC—has quietly expanded its sell policy.

But there’s an interesting tension here: the miners selling Bitcoin to build AI infrastructure are the same companies that secure the Bitcoin network. If enough miners pull out of mining, the network’s security budget shrinks. You can already see it: the hash rate has fallen from 1,160 exahashes per second in October to about 920 EH/s, with three consecutive negative difficulty adjustments—the first time since July 2022.

The market has long since priced this in. Miners with secured HPC contracts are valued at 12.3 times their next twelve months’ revenue, while pure miners are valued at only 5.9 times. This further strengthens the incentive for additional reallocation.

Ultimately, it comes down to one variable: the Bitcoin price. If BTC rebounds to $100,000, mining margins recover and the rush to AI slows down. If the price stays at $70,000 or below, the transformation accelerates, and the mining sector as we knew it disappears into something completely different. The next few months will be decisive.
