Bernstein Says Bitcoin Miners Are Becoming Critical AI Infrastructure Suppliers

Bitcoin mining margins have tightened since the network’s April 2024 halving cut the block reward to 3.125 BTC, leaving operators more exposed to bitcoin prices, network difficulty and power costs. Public miners have responded by repurposing grid connections, land and data-center capacity for artificial intelligence and high-performance computing, where multiyear hosting contracts can provide steadier cash flow. The shift is recasting listed miners as digital-infrastructure companies rather than pure proxies for bitcoin production.

BlocksBridge Consulting said in an analysis published Aug. 13, 2026, that aggregate hashrate among publicly traded bitcoin miners fell 13.4% over six months as capacity moved toward AI and HPC. TeraWulf’s second-quarter HPC leasing revenue rose 52% from the prior quarter to $31.9 million, accounting for 71% of total revenue, while bitcoin-mining revenue dropped 73% year on year to $12.8 million. Core Scientific also generated most of its revenue from non-mining operations, underscoring the sector’s accelerating pivot.

Artificial-intelligence developers are running into a constraint that money and GPUs alone cannot quickly solve: access to grid-connected power and ready data-center sites. Bernstein says Bitcoin miners have become strategic infrastructure partners because they already control large energy portfolios, land and operating facilities built for power-intensive computing. Repurposing that capacity for AI can shorten deployment timelines while giving miners more predictable, contracted revenue than the volatile economics of producing Bitcoin.

In a July 23 research note, Bernstein maintained an overweight view on Bitcoin mining, saying its deal tracker recorded an AI-related agreement every week in July. Announced transactions now exceed 7.5 gigawatts and represent more than $150 billion of multi-year contract value. On July 20, Hut 8 unveiled a 15-year, $9.8 billion lease for its Texas AI campus, while IREN disclosed $2.8 billion of cloud-services contracts with AI developers, helping mining-linked shares post double-digit gains.

Bitcoin miners are increasingly repurposing power-rich sites and data-center expertise for artificial intelligence and high-performance computing as mining economics weaken. Operators such as Hut 8 and IREN can bring capacity online faster than many greenfield developers because they already control grid connections, land and infrastructure. Long-term AI leases and cloud contracts also promise steadier revenue than cryptocurrency mining, making the transition a central driver of investor valuations across the sector.

On July 20, Hut 8 announced a second 15-year, $9.8 billion lease at its Beacon Point campus in Texas, taking the site's combined base-term contract value to $19.6 billion. IREN disclosed $2.8 billion of new multi-year cloud contracts and raised its year-end 2026 AI Cloud annualized revenue target to more than $4 billion, with about 85% under contract. Hut 8 and IREN shares rose more than 16% and 17%, respectively, while several mining peers gained at least 11% in early trading.

AI training and inference are driving a surge in data-center electricity demand, but building new substations and securing grid connections often takes years. Bitcoin miners already control large-scale power contracts, land, substations and fiber connectivity, allowing them to take on AI and high-performance computing workloads faster than projects built from scratch. Success still depends on cooling systems, building retrofits and long-term customers.

A June 30 report said mining sites' grid connections had evolved from a cost of Bitcoin production into an AI asset. On February 26, 2025, Core Scientific expanded its CoreWeave contract to 590 MW, with estimated revenue of $10.2 billion over 12 years. On January 16, 2026, Riot Platforms signed a 10-year, $311 million lease with AMD, beginning with 25 MW and offering expansion to as much as 200 MW.

Bitcoin completed its fourth halving on April 20, 2024, cutting the block reward from 6.25 to 3.125 Bitcoin. Combined with high energy and equipment costs, the reduction has continued to squeeze mining margins. Large miners are therefore converting their existing power capacity, facilities and cooling systems into AI and high-performance computing data centers in pursuit of more stable, long-term revenue.

Shares of miners making major bets on AI have recently far outperformed Bitcoin, but valuations have begun to diverge based on power capacity, financing capabilities and progress in delivering data centers. Nvidia’s plan to issue $20 billion in bonds to fund its AI expansion underscores strong demand for computing infrastructure. It also highlights the substantial capital spending and execution risks miners still face in making the transition.

Bitcoin mining relies on miners deploying computing equipment to secure the network with hashrate and compete for block rewards. As energy, equipment and financing costs have risen and mining revenue has come under pressure, large U.S. miners have begun redirecting capital and power resources toward AI data centers. The shift could reduce hashrate concentration and make the Bitcoin network more decentralized.

Bitcoin's network hashrate fell about 4% from the previous period in the first quarter of 2026, ending five years of growth and marking its first first-quarter decline since 2020. With mining economics deteriorating, several miners are adjusting capital spending and converting existing sites to meet demand for AI infrastructure.
