The Bitcoin mining industry is undergoing the most fundamental transformation in its history, and the clearest sign is not the hash rate or the difficulty adjustments. It’s the balance sheets.
CoinShares’ Q1 2026 mining report, published this week, reveals that the weighted average cash cost to produce a bitcoin among listed miners rose to approximately $79,995 in the fourth quarter of 2025.
Bitcoin has been trading in the $68,000 to $70,000 band, with a CoinDesk report last week estimating losses of $19,000 per BTC mined.
These numbers are not sustainable and the industry knows it. The answer has been a wholesale pivot towards artificial intelligence infrastructure that is reshaping what these companies actually are.
Over $70 billion in cumulative AI and high-performance computing contracts have now been announced across the public mining sector, according to the CoinShares report. CoreWeaves’ expanded deal with Core Scientific alone is worth $10.2 billion over 12 years. TeraWulf has $12.8 billion in contracted HPC revenue. Hut 8 signed a 15-year, $7 billion lease for artificial intelligence infrastructure at the River Bend campus. Cipher Digital has a multi-billion dollar deal with Google-backed Fluidstack.
Publicly traded miners could derive as much as 70% of their revenue from artificial intelligence by the end of 2026, up from around 30% today. Core Scientific’s AI colocation revenue already accounts for 39% of its total revenue. TeraWulf is at 27%. IREN is at 9% and scales rapidly with up to 200 megawatts of liquid cooled GPU capacity under construction.
This means that these mining companies are increasingly becoming data center operators who happen to still be mining bitcoin on the side.
Economics explains why. According to CoinShares, the cost difference between bitcoin mining infrastructure of around $700,000 to $1 million per megawatt and AI infrastructure of $8 million to $15 million per megawatt is large, but AI offers structurally higher and more stable returns.
Hash price, the metric that determines miners’ earnings per unit of computing power, hit a post-halving record low of around $28 to $30 per petahash per day in early March.
At these levels, miners running mid-generation hardware need access to electricity below $0.05 per kilowatt-hour to remain cash-profitable. Meanwhile, AI infrastructure contracts promise margins in excess of 85% with multi-year revenue visibility.
How the economy works
The transition is being financed in two ways, and both are visible in the data, the report explained.
Debt first. The sector’s overall leverage has changed fundamentally. IREN now carries $3.7 billion in convertible bonds across five series. TeraWulf has $5.7 billion in total debt, split between convertible notes and senior secured notes of its compute subsidiary.
Cipher Digital issued $1.7 billion in senior secured notes in November, causing its quarterly interest expense to rise from $3.2 million for the first nine months to $33.4 million in the 4th quarter alone. These are not debt loads in mining. These are infrastructure-scale bets that AI revenues will materialize quickly enough to service the liabilities.
Second, bitcoin sales. Publicly listed miners have collectively reduced their BTC coffers by over 15,000 BTC from peak levels. Core Scientific sold about 1,900 BTC worth $175 million in January and plans to liquidate virtually all remaining holdings in Q1 2026. Bitdeer reduced its treasury to zero in February. Riot Platforms sold 1,818 BTC worth $162 million in December.
Even Marathon, the largest public holder of 53,822 BTC, quietly expanded its policy in its 10-K filing to approve sales from its entire balance sheet, driven in part by pressure on its $350 million bitcoin-backed credit facility, where the leverage rose to 87% as prices fell toward $68,000.
The miners who sell bitcoin to fund AI builds are the same companies whose mining secures the bitcoin network. It creates a tension at the heart of the transition. When mining is unprofitable and AI is lucrative, the rational economic decision is to reallocate capital away from mining. But if enough miners do that, the network’s security budget shrinks.
The hashrate data already reflects this. The network peaked at approximately 1,160 exahashes per second at the beginning of October 2025 and has since fallen to approx. 920 EH/s, with three consecutive negative difficulty adjustments, the first such streak since July 2022.
The valuation market has already priced the bifurcation. Miners with secured HPC contracts are now trading at 12.3 times trailing twelve month revenue. Pure-play miners trade at 5.9 times. The market is paying more than double for the AI exposure, reinforcing the incentive to pivot further.
Meanwhile, the geographical picture is changing alongside the economy. The US, China and Russia now control about 68% of the global hash rate. In the 4th quarter alone, the US gained about 2 percentage points of market share.
But emerging markets enter the picture. Paraguay and Ethiopia have joined the global top 10 mining countries, powered by HIVE’s 300 megawatt operation in Paraguay and Bitdeer’s 40 megawatt facility in Ethiopia.
Hashrate forecasts and estimates
CoinShares predicts that the network’s hash rate will reach 1.8 zetahashes by the end of 2026 and 2 zetahashes by the end of March 2027, one month later than previously predicted.
But that forecast depends on bitcoin recovering to $100,000 by the end of the year. If prices remain below $80,000, CoinShares expects the hash price to continue to fall and the hash rate to drop further as more miners leave.
A sustained move below $70,000 could trigger greater capitulation, which paradoxically benefits survivors through lower difficulty.
Next-generation hardware offers a potential lifeline. Bitmain’s S23 series and Bitdeer’s proprietary SEALMINER A3, both of which operate below 10 joules per second. terahash, is expected to scale through the first half of 2026. These machines would roughly halve the energy costs per bitcoin compared to current mid-generation fleets. But implementing them requires capital, which many miners are directing towards AI instead.
The Bitcoin mining industry entered this cycle as a group of companies securing the network and accumulating bitcoin. It’s exciting as a group of companies building AI data centers and selling bitcoin to fund them.
Whether it is a temporary response to unfavorable economics or a permanent structural shift depends on one variable: the price of bitcoin. If it returns to $100,000, mining margins will be restored and the AI pivot will slow down. If it stays at $70,000 or below, the transition accelerates and the mining sector as it has existed for the past decade continues to fade into something else entirely.
