Bitcoin miners racing to repurpose their data centers for artificial intelligence are staring at a roughly $50 billion near-term funding shortfall, according to a new analysis from investment manager VanEck. The firm estimates the sector's long-term capital expenditure needs at $221 billion, with current cash positions covering only a fraction of that. VanEck uses 'gross energized power' — megawatts actually switched on — as the key valuation metric for miners pivoting to AI, and says the market is increasingly punishing companies that miss construction milestones.
Why execution matters more than megawatts
VanEck's deal tracker shows that miners have delivered only about 25% of their leased capacity so far, and that figure is expected to decline further before improving in 2027-2028. The firm argues that the execution gap is the dominant valuation driver today. Companies with physical leases already in place — Cipher Mining, Hut 8, and TeraWulf — trade above 10 times gross energized power. By contrast, Marathon Digital and CleanSpark trade at just 2-6 times, reflecting the market's skepticism about their ability to deliver on AI infrastructure projects.
Few companies have prior experience building AI data centers, so project management credentials are becoming as important as raw megawatt counts. Missing construction deadlines risks structural de-ratings, VanEck warns.
Who's most exposed to the funding crunch
HIVE Digital faces the most acute funding strain relative to its market cap, according to VanEck. IREN and KEEL carry the next heaviest near-term loads, while TeraWulf and Cipher are relatively better-positioned. Companies with large Bitcoin treasuries — Marathon Digital holds 35,303 BTC, CleanSpark 13,561 BTC, Hut 8 13,696 BTC — can monetize those holdings to fund construction. IREN, which has no Bitcoin treasury, will likely need to turn to dilutive equity or debt.
VanEck's deal tracker also identifies Bitdeer, HIVE Digital, Riot Platforms, and Core Scientific as being in active or advanced lease negotiations. TeraWulf is in advanced talks for a 480MW site in Kentucky.
Bitcoin price risk is unevenly distributed
VanEck argues that the market overstates the sector's overall sensitivity to Bitcoin's price. Only Marathon Digital (~98% of market cap), CleanSpark (~53%), and Riot Platforms (~23%) have meaningful balance-sheet exposure. Core Scientific, TeraWulf, Applied Digital, and IREN have effectively decoupled from Bitcoin's price. A drop in Bitcoin to $50,000 would erase roughly 45% of Marathon's equity value and nearly 50% of HIVE's, but only 4% of Hut 8's.
What comes next
VanEck expects valuations to eventually migrate away from simple megawatt counts toward delivery ratios, unit economics, and discounted cash flow models. Over time, these companies could come to resemble data center REITs rather than crypto miners. For now, the $50 billion gap means the next few quarters will test which firms can actually build what they've promised.
