Bitcoin Miners Face $50B Funding Gap As AI Pivot Separates Winners From Losers
A new draft from asset manager VanEck draws clear lines between Bitcoin miners who are truly transforming into artificial intelligence infrastructure providers and those who are still selling the story. It all comes with a sobering price tag: a nearly $50 billion financial gap that stands between the industry’s pipeline ambitions and actual delivery.
In a research note, VanEck investment analyst Griffin MacMaster and Head of Digital Asset Research Matthew Sigel laid out what they described as the first systematic valuation of an increasingly diminutive category of companies dealing with Bitcoin mining and AI data center hosting.
Since financial disclosures vary widely across the industry and cash flows are still small, VanEck says the cleanest metric available to investors right now is the maximum capacity — actually, how many megawatts a company has turned off, not just what’s announced.
The gap between those two things is becoming apparent. Companies with physical leases in hand – including Cipher Mining (CIFR), Hut 8 (HUT), and TeraWulf (WULF) – command values of more than 10x the leveraged capital.
Meanwhile, names like Marathon Digital (MARA) and CleanSpark (CLSK), which remain closely related to Bitcoin mining with limited capacity for contracted AI, trade at just 2–6x on that same metric.
“At the moment, we find that the market is paying for the contract volume and capacity, while the discount is still ongoing,” the analysts wrote.
Signing contracts, VanEck cautions, is just the beginning. Across the peer group, miners have delivered only about 25% of their lease capacity – a figure the company expects to decline further before improving, as major construction projects begin in 2027 and 2028.
That execution gap is expected to be a key driver looking forward, with companies that miss construction milestones risking what VanEck calls “structure reduction rates.”
Analysts also point out that very few of these companies have previous experience building the kind of infrastructure that AI customers need – making project management credentials as important as megawatt figures.
The VanEck tracker shows a busy second half of 2026, with several companies — including Bitdeer ( BTDR ), HIVE Digital ( HIVE ), Riot Platforms ( RIOT ), and Core Scientific ( CORZ ) — in various stages of active or advanced lease negotiations. WULF is described as “advanced negotiations” for a 480MW facility in Kentucky, which is expected to find a customer in the second quarter.
221 billion building – and who can pay for it
The massive demands of this pivot are staggering. VanEck estimates that the sector’s long-term capital spending needs are close to $221 billion, with near-term needs alone creating a combined deficit of about $50 billion over current cash positions.
The dispersal within the group is wide. HIVE is facing the biggest challenges related to its market, driven by its AI Gigafactory ambitions targeting more than 100,000 GPUs. IREN and KEEL carry the next closest heavy loads. In contrast, WULF and CIFR appear to be in a better position, as they have already secured strong contracts that help de-risk their capital increases.
The ways to get money are very diverse. Companies with Bitcoin Treasury Holdings – including MARA (35,303 BTC), CLSK (13,561 BTC), and HUT (13,696 BTC) – can rely on Bitcoin monetization strategies to fund the construction phase.
REN, with a huge need for near-term funding that no BTC treasury can take on, is faced with a narrow set of options: issuing dilutive shares or rising debt.
VanEck: Bitcoin’s exposure is overstated
This report also challenges how the market correlates the entire group with Bitcoin prices. While the group’s average daily return on BTC is running at around 0.55 year to date and the one-year beta remains at around 1.05, VanEck argues that the volatility exceeds Bitcoin’s true sensitivity to the sector in companies that have advanced significantly.
Only MARA (with sensitive BTC value equal to ~98% of market cap), CLSK (~53%), and RIOT (~23%) carry meaningful balance sheet exposure to Bitcoin price fluctuations. On the other hand, CORZ, WULF, APLD, and IREN have successfully split.
The analysis shows that Bitcoin’s drop to $50,000 would wipe out about 45% of MARA’s equity value and nearly 50% of HIVE’s, while shaving just 4% of HUT’s – underscoring how the “one BTC trade” framework misrepresents the group’s situation.
VanEck expects the scale to eventually move from megawatt calculations to delivery metrics, unit economics, and eventually discounted cash flow models — where these companies will begin to resemble data center REITs more than miners.
The company expects many to eventually be sold or converted to REITs as AI revenues mature.
Currently, VanEck sees the greatest rebalancing potential in the names with the largest gap between ambition and current market values - HIVE, KEEL, IREN, and Bitdeer – while acknowledging those same names have the highest risk of execution. Companies with anchor pooling agreements already in hand, such as WULF, CIFR, and HUT, offer a solid way to pool that leverage into a long-term marketplace.
