Bitcoin miners face $50 billion gap in AI data center pivot

Publicly traded Bitcoin miners pivoting to artificial intelligence infrastructure face an estimated $50 billion near-term funding gap, according to VanEck.

"Investors should increasingly value miners based on gross energized power rather than Bitcoin production," the asset manager said in a report published Tuesday.

Companies with signed AI leases — including Cipher Mining, Hut 8 and TeraWulf — trade at more than 10 times gross energized power, VanEck found. By contrast, Marathon Digital and CleanSpark, which are still marketing future capacity, trade at roughly 2 to 6 times that metric. Cipher anchored its premium with a nearly $5.5 billion, 15-year lease with Amazon Web Services for 300 megawatts of AI capacity beginning July. Hut 8 stacked a $9.8 billion, 352 MW Texas deal on top of a $7 billion Louisiana lease with Google-backed Fluidstack. TeraWulf locked in $3.7 billion in Fluidstack contracts at its Lake Mariner campus, with Google providing a $1.8 billion backstop in exchange for an 8% equity stake.

The funding gap highlights the scale of capital required to convert Bitcoin mining infrastructure into AI-ready data centers. VanEck estimates long-term capital requirements reach roughly $221 billion, and companies that miss delivery targets face sharp valuation re-ratings.

Signed deals, delivered capacity

VanEck estimates the group has delivered only about 25% of leased capacity to date, meaning construction milestones — not deal announcements — will drive the next phase of valuations. Hut 8 alone is seeking up to $3.25 billion in senior secured notes for its Louisiana buildout, while Cipher is raising $810 million through a subsidiary to finance its AWS-anchored Stingray facility.

The financing challenge is compounded by the revenue gap between the two industries. Crypto trader Ran Neuner argued that AI data centers generate $200 to $500 per megawatt in revenue, compared with $57 to $129 for Bitcoin mining, making the financial case for switching straightforward. Bitcoin's hash rate has fallen 14.5% since its October peak, he said, as miners redirect power to AI workloads.

HIVE and IREN lead the pivot

HIVE Digital Technologies this week announced a $220 million GPU cloud contract with Bell Canada and AI firm Cohere, deploying 2,304 NVIDIA Grace Blackwell GPUs at Bell's facility in Merritt, British Columbia. The three-year deal pushes HIVE's contracted high-performance computing revenue past $100 million and is expected to add roughly $70 million in new annual recurring revenue once the deployment goes live between late 2026 and early 2027.

IREN, meanwhile, received a Buy rating and $79 price target from Jefferies, which highlighted the company's 6-gigawatt powered land bank and contracts with Microsoft and Nvidia that could support roughly $3.1 billion in annual recurring revenue. The Microsoft deal, signed in November 2025, includes a 200-megawatt lease at IREN's Childress facility and a five-year contract worth an estimated $9.7 billion tied to Nvidia's GB300 GPU capacity.

Not all analysts share the bearish view on Bitcoin mining's future. Bitcoin pioneer Adam Back said the network's difficulty adjustment mechanism handles miner exits as designed, with profitability for remaining miners converging toward AI-equivalent returns. Bitcoin ESG specialist Daniel Batten argued that AI expansion is dependent on Bitcoin mining's ability to use stranded energy and act as a flexible load balancer for power grids.
