Public miners shift BTC power to AI

TLDR

Several publicly listed Bitcoin miners are reallocating part of their mining infrastructure to AI and high-performance computing, cutting their share of BTC hashpower in favor of data-center revenue.

1. Public miners have reduced their collective Bitcoin hashrate by about one fifth while ramping AI and HPC contracts, including multi-billion dollar deals for GPU compute.
2. The pivot is driven by weak post-halving mining economics and much higher, longer-term revenue visibility from AI data-center leases than from pure BTC production.
3. For crypto users, this reshapes Bitcoins security budget and how miner stocks are valued, making compute capacity and AI contracts key metrics to watch alongside hashpower.

Deep Dive

1. Miners Reallocating Hashpower

Recent earnings and network data show that public Bitcoin miners have cut their realized hashrate, with their cohorts share down about 21% as AI/HPC revenue accelerates, while the overall network hashrate is down roughly 10% in the same window. This reflects miners shutting rigs and repurposing power rather than a broad collapse in Bitcoin security.

Operators like Core Scientific, TeraWulf, Cipher Digital, IREN and Keel Infrastructure are dismantling or redirecting mining fleets for AI and high-performance computing, as detailed in an analysis of public miners shedding 21% of Bitcoin hashrate. Others such as Bitdeer, Marathon, Riot Platforms and American Bitcoin are still growing or holding mining share, but they are increasingly adding AI cloud or data-center lines.

A headline example is Riot Platforms 9 billion dollar, 20-year compute deal with Anthropic, covering 191 megawatts of capacity at its Texas facility. That contract explicitly marks a strategic shift from pure Bitcoin mining toward being an AI infrastructure provider.

2. Economics Behind The Shift

Mining profitability, often tracked via hashprice (revenue per unit of hashpower), has fallen sharply since 2021 and is under extra pressure after the 2024 halving cut block subsidies in half. In this environment, miners with large power contracts and built-out sites can often earn more by hosting GPUs for AI workloads than by running ASICs for BTC.

Earnings show this clearly. Core Scientifics Q2 colocation revenue of 136.7 million dollars was about five times its Bitcoin mining revenue of 27.5 million dollars, while TeraWulf derived roughly 71% of revenue from HPC leases versus 29% from mining, according to the same miner revenue breakdown. Riot already reports tens of millions in data-center revenue alongside mining, and its Anthropic contract could add hundreds of millions per year once fully ramped.

Mining facilities have advantages as AI data centers: they already control land, interconnection to the power grid and cooling infrastructure, which are the main bottlenecks for new AI sites. Hardware, staffing and permitting must still change, but the revenue per megawatt and duration of AI leases can be far more attractive than volatile BTC rewards.

3. Impact On Bitcoin And Valuations

For Bitcoin, a lower share of public-miner hashrate and some regional bans aimed at preserving grid capacity for data centers, such as Russias mining shutdowns around Moscow, rewrite the security budget. A modest hashrate decline is not yet a crisis, but if more power permanently leaves BTC for AI, the cost to attack the network falls unless price, fees or private miners capacity rise to compensate.

For listed miner stocks, analysts now value them less on BTC holdings and more on total approved megawatts, signed AI/HPC contracts and data-center revenue trajectories. Coverage of Riots Anthropic deal stresses that AI is now the key to valuing Bitcoin mining stocks, emphasizing capacity and contract duration over pure hashpower metrics, as seen in recent miner valuation commentary.

Confidence: high. Multiple miner earnings reports and independent analyses corroborate both the hashrate decline and the rapid growth of AI/HPC revenue.

Conclusion

Public Bitcoin miners are increasingly redirecting electricity and infrastructure from hashing blocks to running GPUs for AI, because long-term data-center leases currently pay better than volatile BTC rewards. That shift lowers the portion of global hashpower controlled by listed miners and pushes investors to value these companies on their compute capacity and AI contracts instead of just their Bitcoin stacks. For crypto users, the key is to watch how far this reallocation goes and whether Bitcoins total hashrate, fees and price keep its security budget robust as mining and AI compete for the same power resources.
