Bitcoin miners are remodeling themselves as energy and data center companies, driven by weakening mining economics and surging demand for artificial intelligence capacity.
That switch is creating new opportunities for mining companies, but also new risks for Bitcoin’s network security.
Mining revenue is under pressure from lower Bitcoin prices and shrinking block rewards. Meanwhile, the power contracts, land, and data center sites that large miners spent years assembling are now coveted by AI customers.
Corporate Bitcoin miners are largely embracing the shift, including IREN, TeraWulf and Cipher. Publicly traded mining companies are collectively investing billions of dollars to acquire power-heavy sites and build out data center capacity.
“This is not a temporary curtailment but a full pivot away from Bitcoin mining,” VanEck analysts Patrick Bush and Matthew Sigel wrote in a May 22 report.
The pivot is unlikely to break Bitcoin’s security model, but it could shift more of the network away from U.S. public miners and toward lower-cost operators. The VanEck analysts said older mining machines could find a home with “sovereign […] buyers with cheap power and long time horizons.”
“We believe that the [Bitcoin mining] hardware will find the energy,” they wrote.

Bitcoin Mining Margins Under Pressure
Tighter margins are eroding Bitcoin miners’ business model.
Miners earn BTC when they successfully add new blocks of transaction data to the Bitcoin blockchain. Bitcoin is a volatile asset, but mining costs—including power, equipment, and debt payments—are relatively fixed. That means mining is heavily exposed to market cycles.
The 2024 halving added to the pressure by cutting the block subsidy to 3.125 BTC from 6.25 BTC. Since then, miners have competed for a smaller reward. The strain deepened in 2026, as Bitcoin’s (BTC) price dove by more than 30%, according to CoinMarketCap.
Hashrate Index said miner revenue per unit of computing power hit an all-time low in February. By June, network hashrate, or the total computing power securing Bitcoin, had fallen to 874 exahashes per second from 1,011 EH/s—a sign that miners are taking capacity offline.
Part of that capacity is being repurposed for AI.
“Right now [investing more in Bitcoin mining] doesn’t make sense. So we want to be redirecting every dollar possible toward AI capex,” CleanSpark President and CFO Gary Vecchiarelli said during the company’s first quarter earnings call.

The Bitcoin Miner Power Play
Bitcoin miners have built large power portfolios because mining depends on cheap electricity. Now, AI companies are bidding aggressively for the same resources, including power, land, cooling, fiber, and data center sites.
Miners are cashing in—and investing billions of dollars in expansion.
IREN said on June 1 that it closed a $3.65 billion financing facility tied to its AI cloud contract with Microsoft. TeraWulf said on May 26 that it acquired an eastern Kentucky site expected to eventually support more than 1 gigawatt of data center capacity. Cipher is currently raising $810 million to fund a West Texas data center servicing Amazon.
Miners are likely to keep doubling down. AI contracts offer steady, long-term revenue backed by large clients. That’s an attractive proposition for miners accustomed to Bitcoin’s wild price swings.
“We are fundamentally a power company that builds digital infrastructure, not the other way around,” TeraWulf CEO Paul Prager told investors in May.

Navigating the Shift to AI
In theory, the retreat of large corporate miners could create risks for Bitcoin’s network security.
If miners shift power to AI, Bitcoin’s network can slow and become cheaper to attack. But the system is designed to adjust, reducing the computing power needed to add new blocks until network activity normalizes.
The bigger shift may be in who is running the mining rigs. If U.S. public miners lock power into AI contracts, more hashrate could move to lower-cost private operators or overseas miners.
Still, experts say the network itself will endure.
“The built-in incentives have always adjusted and kept mining a well-incentivized activity,” Mark Zalan, CEO of GoMining, told Cointelegraph Magazine. “And we think it will continue to be that way going forward.”
