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 has the potential to flatten Bitcoin’s hashrate while giving miners a second source of income, as major operators reorient energy infrastructure away from pure mining and two hyperscaler contracts set a specific 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’ trailing weighted average cash cost to approximately $79,995 per coin. $BTC By the first quarter of 2026, we will encourage operators to use AI hosting as a revenue stabilizer to lease unused capacity, keep mining rigs running, and offset Bitcoin’s worst 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 not be able to keep up $BTC Single price
Bitcoin mining expansion has historically followed the price, with miners ordering more machines. $BTC Cutting capacity when raised and lowered.
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 hash price for surviving miners will rise to around $44.85 per PH/day, while an exit at 30% will bring it to around $51.26, otherwise still well short of Fidelity’s AI crossover. $BTC Prices and transaction fees will increase 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 A move from $100,000 to $140,000 or a significant increase in transaction fees will cause the economics to readjust.
When the network hash rate is reduced by 20%, $BTC The price needed to reach the $60-$70 AI crossover is about $98,000 to $114,000, and a 30% reduction lowers that threshold to about $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.
Fewer large public miners in the hashrate mix also reduces forced miners. $BTC A selloff that has historically weighed on spot prices during economic 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 is under $70,000 to $80,000, fees remain low, power prices remain high, and the economics of contracted GPU hosting dominate 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 keep the network running at any exit, mining’s center of gravity shifts as large-scale public miners with AI-enabled infrastructure grow > Microsoft’s contract includes explicit delivery clauses that Reuters reported could trigger termination if milestones are not met, and miners saddled with large debts along with delayed AI revenue face re-pricing of their stock from Bitcoin proxies to execution-risk assets.
division is the result
The competition between ASICs and GPUs for miner capital will play out on a site-by-site, operator-by-operator basis, subject to the power contracts already signed. $BTC Price at next halving.
Bitcoin network absorbs hashrate exit through lower and higher difficulty levels $BTC Prices and fees could push the economics back into mining for operators that don’t already provide power 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 the next generation of power campus construction depends on where it depends. $BTC The price has settled around $35.88, and the question once again arises as to how many more hyperscalers will emerge with 15-year checkbooks before the next halving.
