I just noticed something that most people overlook: Bitcoin miners are currently turning into something completely different. Not gradually, but quite radically.

The numbers are simply brutal. Publicly traded BTC miners are currently losing about $19,000 per mined Bitcoin, while production costs have risen to nearly $80,000 per coin. Bitcoin is fluctuating around $72,000 – that’s economically unsustainable. Any sensible manager would look for other opportunities.

And that’s exactly what’s happening right now. The industry’s response to this crisis is a massive shift toward AI and high-performance computing. We’re talking about over $70 billion in signed contracts in the AI and HPC sectors. Core Scientific has a $2.03M deal with CoreWeave over 12 years. TeraWulf has $12.8 billion in contractually secured HPC revenue. This is no longer fringe business – it’s the new core strategy.

The logic behind this is actually simple. A BTC miner needs about $700,000 to $1 million in infrastructure per megawatt. AI data centers cost $8 to $15 million per megawatt. But AI contracts offer margins over 85% with multi-year visibility. Bitcoin mining just doesn’t generate enough profit right now. That’s why these companies are now effectively becoming data center providers that also mine Bitcoin on the side.

By the end of 2026, the share of AI revenue could reach 70% for some miners, compared to about 30% today. Core Scientific already makes 39% of its revenue from AI. That’s the real business now.

How are they financing this? In two ways. First, massive borrowing. IREN now holds $3.7 billion in convertible bonds. TeraWulf has a total of $5.7 billion in debt. Cipher Digital issued $1.7 billion in secured bonds in November. These are no longer classic mining debts – they’re infrastructure-scale bets.

Second, Bitcoin sales. Publicly traded BTC miners have reduced their holdings by over 15,000 Bitcoin. Core Scientific sold about 1,900 BTC in January for $175 million and plans to liquidate nearly all remaining holdings in the first quarter. Bitdeer reduced its holdings to zero. Even Marathon, the largest public Bitcoin holder with over 53,000 BTC, has quietly expanded its selling policy.

But a real tension is emerging here. Miners selling Bitcoin to build AI infrastructure are the same companies that secure the Bitcoin network. If enough miners reduce their hash power, network security declines. And that’s what we’re seeing now: the hash rate dropped from about 1,160 exahashes per second in October to just under 920 EH/s. Three consecutive negative difficulty adjustments – the last time that happened was in July 2022.

The market has already priced this in. Miners with secured HPC contracts are valued at 12.3 times their next twelve months’ revenue. Pure BTC miners only at 5.9 times. The market is paying more than double for AI exposure. This only increases the incentive to pivot further.

Where does this lead? CoinShares forecasts that the network hash rate will rise to 1.8 zettahashes by the end of 2026 and reach 2 zettahashes by March 2027. But that assumes Bitcoin returns to $100,000 by year’s end. If the price stays below $80,000, the hash price will continue to fall, and even more miners will exit. Below $70,000, a larger capitulation could follow.

The next-generation hardware – Bitmain’s S23 series and Bitdeer’s proprietary SEALMINER A3, both under 10 joules per terahash – could provide a lifeline. These would cut energy costs per Bitcoin roughly in half. But acquiring them requires capital that many miners prefer to invest in AI.

This is the most fundamental transformation the mining industry has ever undergone. The sector begins this cycle as a group of companies securing the network and accumulating Bitcoin. It ends as a group building AI data centers and selling Bitcoin. Whether this is temporary or a permanent shift depends entirely on the Bitcoin price. Return to $100,000 and margins recover. Stay below $70,000, and the shift accelerates, with the mining sector as we knew it disappearing into something entirely different.
