Bitcoin Miners Pivot to AI as Power Assets Outvalue Mining

Bitcoin mining is no longer just about securing blocks. It is a real estate and power play. The race to secure cheap electricity has inverted, turning the underlying power infrastructure into a far more lucrative asset than the mining rigs themselves. Major hyperscalers are now bidding up these sites, forcing a structural shift in how public miners allocate their capacity.

Two massive deals signed by Cipher Mining and IREN show the scale of this transition. Cipher locked in a $5.5 billion, 15-year lease with AWS to provide 300 megawatts of turnkey space for AI workloads starting July 2026. Meanwhile, IREN secured a $9.7 billion, five-year GPU cloud contract with Microsoft to deploy Nvidia GB300 GPUs at its 750 MW Texas campus.

The economics of pure-play mining have deteriorated rapidly since the 2024 halving. CoinShares data shows the weighted-average cash cost for tracked public miners climbed to roughly $79,995 per BTC in the first quarter of 2026. With the US dollar hash price sitting at a depressed $35.88 per petahash per day as of May 25, miners are facing a stark choice.

Fidelity's analysis puts the mining-to-AI crossover price at $60 to $70 per PH/day for a standard 20-joule-per-terahash fleet. This means the current hash price would need to surge up to 95% just to match the guaranteed economics of hosting GPUs for tech giants. AWS and Microsoft have effectively established a valuation floor for mining infrastructure that the Bitcoin network cannot currently compete with.

CoinShares estimates that public miners' AI and high-performance computing contracts surpassed $70 billion in early 2026. Listed operators are on track to draw up to 70% of their revenue from AI by the end of the year, up from 30%. Traders should watch the upcoming July launch of Cipher's AWS contract and the pace of hash rate stagnation as more gigawatts are permanently diverted from the blockchain to the cloud.
