Bitcoin’s network power dipped this week, falling back under the one-zettahash mark after several months above it. Reports show the seven-day average hashrate near 993 EH/s, a clear pullback from last year’s highs.
Hunger For Power
Reports say big AI data centers are buying long-term power contracts and willing to pay more for steady, round-the-clock electricity, pushing some miners to cut or shift operations. This competition has changed who gets the cheapest power on the grid.
Some publicly traded miners are closing deals to lease space to chipmakers and AI firms, turning parts of their sites into AI data centers. One large miner signed a multi-year lease with a major chip company, showing how companies are hedging against volatile mining profits.
On Monday, StandardHash CEO and founder Leon Lyu said on X that the drop came as Bitcoin miners shifted electricity toward AI computing to chase better profit margins.
Why The Shift Matters Now
Electricity is the single biggest cost for mining. When data centers bid for the same megawatts, miners face a straight choice: pay more, accept narrower margins, or repurpose capacity.
Bitcoin Hashrate Alert: A Shift in the Mining Landscape 📉
For the first time since Sept 2025, BTC’s 7-day average hashrate has fallen below 1 ZH/s. A -4.34% difficulty adjustment is expected in ~3 days.

The network’s difficulty has been eased a bit by the drop in hashpower, which keeps block times roughly steady, but that mechanical fix does not change who holds the power contracts.
PJM, the grid operator serving the mid-Atlantic, has moved quickly to propose rules aimed at handling surging AI demand.
The plan asks large new power users to take responsibility for their own supply or accept curtailment rules so essential services and homes do not face outages. These moves are meant to limit the strain that rapid AI growth could place on the system.

Bitcoin Vs. AI: Policy Moves And Political Pressure
US President Donald Trump and several state leaders have urged steps that would make tech firms pay more to secure power, including proposals for emergency auctions to fund new plants.
The pressure reflects worry about higher bills and the risk that expanding data centers could crowd out other users.
What Miners Are Doing To Stay Alive
Many operators are not only shutting rigs when power gets costly; they are retrofitting sites to host GPUs and other AI hardware.
That change can mean steadier revenue and longer contracts than mining alone would offer. It also signals a structural shift: bitcoin mining is becoming one part of a broader compute business for some companies.
Block rewards and protocol rules still secure the network. But if hashrate stays lower for a long stretch, planners and investors will watch whether centralization rises in places where power stays cheap.
For everyday users, the system keeps producing blocks; for miners, the contest for electricity is now a defining business problem.
