Bitcoin’s network hashrate has been sliding for nearly 287 days. In any other era of crypto, that would be a five-alarm fire. Instead, the stocks of publicly traded mining companies are posting gains that would make a tech investor jealous.
The great power pivot
Bitcoin’s hashrate peaked around 1,157 to 1,160 EH/s in October 2025. Since then, it has dropped roughly 15%, marking a sustained decline that the network hasn’t experienced in years.
Q1 2026 was particularly notable. It registered the first quarterly hashrate decline in six years, with an approximate 4% decrease.
Mining difficulty responded accordingly. June 2026 saw a 10.09% difficulty drop. July followed with another decrease of around 5%.
The reason miners walked away from the table is where the story gets interesting. The 2024 halving cut block rewards in half, compressing already-thin margins to the point where some operators were reportedly losing up to $19,000 per Bitcoin mined. When your core business becomes a money pit, you start looking at what else your massive power infrastructure can do.
From proof of work to proof of profit
Mining companies own something that every AI company on the planet desperately needs: access to large-scale power capacity. Miners already have the substations, the grid connections, and the cooling infrastructure. Redirecting that capacity from SHA-256 hash computations to GPU-based AI workloads is not trivial, but it’s a lot faster than building from the ground up.
Companies like TeraWulf, Cipher Mining, and Hut 8 have leaned into this pivot aggressively. Their stock prices have surged between 45% and 135% year-to-date through mid-May 2026. That’s happening while Bitcoin has traded in a range of $60,000 to $65,000.
Miners have reportedly signed contracts totaling over $70 billion in potential AI deals. That number reflects the sheer intensity of competition for energy resources among hyperscalers, AI startups, and legacy tech companies all scrambling to secure compute capacity.
A long-term AI hosting contract with a creditworthy counterparty is a fundamentally different revenue stream than mining Bitcoin. It’s more predictable, often higher-margin, and doesn’t depend on a volatile token price or the whims of the next halving cycle.
The investment calculus
For investors, the takeaway is a bifurcation that’s already visible in the data. Bitcoin the asset and Bitcoin miners the equities are diverging in ways that haven’t been seen before.
The risks are real, though. AI infrastructure demand could cool if the broader AI trade reverses. Those $70 billion in potential deals are just that: potential. Contract terms, execution risk, and the capital expenditure required to retrofit mining facilities for AI workloads all introduce uncertainty.
There’s also a concentration risk worth watching. If the most efficient miners stay on the Bitcoin network while less competitive operators exit for AI, the remaining hashrate could become more centralized among fewer, larger players.
