Bitcoin miners face $50B funding gap as AI pivot demands $221B buildout

Bitcoin miners face a $50 billion near-term funding shortfall converting power assets into AI data centers, per a VanEck framework cited by Blocksbridge Consulting.

Only about 25% of leased AI and high-performance computing capacity has been delivered, and companies that miss construction milestones risk structural de-ratings, Griffin MacMaster, investment analyst at VanEck, and Head of Digital Assets Research Matthew Sigel said in a research note.

IREN leads the cohort with a $21.1 billion funding gap, followed by Riot Platforms at $7.2 billion and HIVE Digital at $4.6 billion, per Miner Weekly. The sector's long-term capital needs approach $221 billion. Companies with signed AI leases — including Cipher Mining, Hut 8 and TeraWulf — command valuations above 10 times gross energized power, while Marathon Digital and CleanSpark, tied to Bitcoin mining, trade at just two to six times that metric.

The capital demands come as mining economics deteriorate. Hashprice fell to roughly $28 per petahash per second in the first quarter, down from about $35 in Q4 2025 — what TheEnergyMag called the harshest margin environment of all time for public miners. At those levels, as many as 20% of miners operated at a loss, CoinShares estimated.

Execution Gap Widens Between Miners With Deals and Those With Ambition

VanEck's analysis draws a sharp line between miners that have secured physical leases and those still selling a story. Companies with contracted and energized capacity are being rewarded, while pipeline projects are discounted, the analysts said. The gap is expected to widen before improving, as large-scale construction kicks off in 2027 and 2028.

Funding capacity varies widely. HIVE faces the most acute strain relative to its market cap, driven by AI Gigafactory ambitions targeting more than 100,000 GPUs. IREN and KEEL carry the next heaviest loads. Companies with Bitcoin treasuries — MARA with 35,303 BTC, CLSK with 13,561 BTC and HUT with 13,696 BTC — can monetize holdings to fund construction. IREN, with no BTC treasury, faces dilutive equity or debt.

Bitcoin Exposure Diverges Across the Sector

VanEck challenges the notion that miners move in lockstep with Bitcoin. While the group's average daily-return correlation to BTC runs about 0.55 year-to-date and its average one-year beta sits at roughly 1.05, only MARA (BTC-sensitive value equal to roughly 98% of market cap), CLSK (about 53%) and RIOT (roughly 23%) carry meaningful balance-sheet exposure. CORZ, WULF, APLD and IREN have effectively decoupled. A drop in Bitcoin to $50,000 would erase roughly 45% of MARA's equity value and nearly 50% of HIVE's, while shaving just 4% off HUT's.

VanEck expects valuations to eventually migrate toward delivery ratios and discounted cash flow models, at which point these companies will resemble data center REITs more than miners. The firm sees the greatest re-rating potential in names with the widest gap between ambition and pricing — HIVE, KEEL, IREN and Bitdeer — while acknowledging those carry the highest execution risk.
