Bitcoin miners spent years competing to secure cheap electricity, which then became more valuable than the Bitcoin mining businesses built on top of it.
This reversal is driving Fidelity’s May 2026 assessment that AI hosting could flatten Bitcoin’s hashrate while giving miners a second source of income, as major operators redirect energy infrastructure away from pure mining and two hyperscaler contracts set a concrete price for what miners build.
In a business update filed with the SEC, Cipher Mining announced an approximately $5.5 billion, 15-year lease agreement with AWS to provide 300 MW of turnkey space and power for AI workloads, with deliveries to begin in July 2026.
IREN has signed an approximately $9.7 billion, five-year GPU cloud agreement with Microsoft to deploy NVIDIA GB300 GPUs through 2026 at its 750 MW campus in Childress, Texas, supporting 200 MW of critical IT workloads.

Miners had already secured rights to the land, grid interconnections, substations, and power needed for AI data centers, but they can’t build them fast enough.
The 2024 halving compressed hash prices, pushing CoinShares’ tracked weighted average cash cost to around $79,995 per BTC by the first quarter of 2026, prompting operators to turn to AI hosting as a revenue stabilizer, leasing unused capacity, keeping mining rigs running and offsetting the worst of Bitcoin’s downturn.
CoinShares estimates that public miners’ AI and HPC contracts will total more than $70 billion by early 2026, with public miners on track to earn about 30% to as much as 70% of their revenue from AI by the end of the year.
This was a revenue hedge, and the Cipher and IREN contracts were then replaced by power campus price discovery.
Price discovery changes internal calculations
Fidelity’s January 2026 analysis found that for a fleet of 20 joules per terahash, the crossover from mining to AI is approximately $60-70 per petahash per day. This means that most 20-25 J/TH miners will need to increase their hash prices by 40-60% to match the economics of their contracted GPU hosting.
Hashrate Index data from May 25 has since extended this distance, with the USD hash price at $35.88 per PH/day, making the AI ​​crossover approximately 67% to 95% higher than the current spot.
Miners leveraging infrastructure that is licensed to provide 300 MW of power are now faced with a choice between deploying an ASIC and earning $35.88 per PH per day, or signing a hyperscaler lease at a contracted rate that would require nearly doubling the hash price to match.
AWS and Microsoft have effectively published the floor on how much their infrastructure is worth to anyone other than Bitcoin, and every major operator with comparable assets is now putting that number into their models.
AI infrastructure costs $8 million to $15 million per megawatt to build, while Bitcoin mining infrastructure costs $700,000 to $1 million per megawatt, and miners who migrate are entering a more capital-intensive business with fundamentally different debt profiles, valuation metrics, and execution risks.
Hashrate may no longer follow only BTC price
Bitcoin mining expansion has historically tracked price, with miners ordering more machines when BTC rises and cutting capacity when BTC falls.
VanEck’s April ChainCheck recorded 30-day hashrate momentum at the 16th percentile and 90-day hashrate momentum at the 9th percentile, making it the densest cluster of sustained hashrate declines since China’s mining ban in 2021.
According to CoinWarz data as of May 28, Bitcoin difficulty is 136.61T, with a 90-day difficulty change of -5.40%, which is consistent with Fidelity’s mining churn situation.
Bitcoin’s 2,016 block difficulty adjustment is still offset by reducing the computational cost of producing a valid block each time the hash rate ends, increasing the revenue per unit of remaining hashes when the difficulty is reset.
If the hashrate exits at 20%, the surviving miner’s hash price will rise to around $44.85 per PH per day, but if it exits at 30% it will rise to around $51.26, which is still well below Fidelity’s AI crossover unless BTC prices and transaction fees rise significantly.
Power locked into a 15-year AWS lease or a 5-year Microsoft GPU contract cannot be returned to mining even if ASIC economics return. In the old cycle, the machine could be switched back on, thus returning an idle hash, but in this cycle, the campus itself could be committed elsewhere.
Bitcoin gets the tougher market it needs
If BTC approaches $100,000 to $140,000 or transaction fees increase significantly, the economics will readjust.
A 20% drop in network hash rate would reduce the BTC price needed to reach the $60-$70 AI crossover from approximately $98,000 to $114,000, and a 30% drop would lower that threshold from approximately $86,000 to $100,000.
Miners still committed to Bitcoin benefit from a market where hash price increases faster than hash rate, compressing the competitive field and increasing profits for operators with efficient fleets and low power costs.
With fewer large public miners in the hashrate mix, there will also be fewer forced BTC sales that have historically weighed down spot prices during expansion cycles.
Charles Schwab’s May 26 analysis argues that a hybrid infrastructure model strengthens Bitcoin’s overall network health. This means fewer forced sales, tougher difficulty conditions, and better miner margins, alleviating the systemic stress that large capital-intensive miners have historically introduced during cycle peaks.
The industry is split into two distinct businesses: those that own power campuses and monetize them through hyperscaler contracts, and those that actually mine Bitcoin. Bitcoin is often mined at lower cost, more flexible or stuck energy sites where AI data centers cannot easily operate.

AI wins allocation decisions
If BTC stays below $70,000-$80,000, fees remain low, and power prices remain high, the economics of contracted GPU hosting will govern internal capital allocation for operators with AI-enabled sites.
CoinShares estimates that an electricity cost of $0.06 per kilowatt hour or more for a machine with S19 XP efficiency or lower would make 15% to 20% of the world’s fleet uneconomical at approximately $30 per PH/day.
Old fleets will be shut down, difficulty will decrease in successive epochs, and surviving miners will earn more per petahash, but for operators who still have that option, it won’t be enough to close the gap between Cipher and IREN’s contracts.
Difficulty adjustments will keep the network up and running at any exit, and the center of gravity of mining will shift as large public miners with AI-enabled infrastructure become landlords of data centers, while Bitcoin’s hash rate will concentrate on operators with cheaper, intermittent, or internationally distributed energy.
IREN’s deal with Microsoft includes explicit delivery clauses that Reuters reported could trigger termination if milestones are not met, and the miners, which are saddled with large debts along with delayed AI revenue, will face re-pricing of their shares from Bitcoin proxies to assets with execution risk.
division is the result
The battle between ASICs and GPUs for miner capital will play out on a site-by-site, operator-by-operator basis, subject to power contracts already in place and the BTC price at the next halving.
Bitcoin’s network absorbs hashrate exits with lower difficulty, and rising BTC prices and fees could push the economics back into mining for operators who haven’t yet focused their efforts elsewhere.
The more permanent result of the AWS and Microsoft deal is that it is now possible to run a large and reliably profitable infrastructure business on the same sites that Bitcoin mining built, without ever mining a single block.
Whether that possibility becomes the default for building the next generation of power campuses will depend on where BTC price settles relative to $35.88, and how many more hyperscalers come in with 15-year checkbooks before the next halving raises the question again.
