Bitcoin Miners Face $50 Billion AI Infrastructure Funding Challenge: VanEck

Bitcoin mining companies that spent the last two years repositioning themselves as AI infrastructure providers are entering a critical stage where execution matters more than announcements, according to a new report from asset manager VanEck.

The report highlights growing concerns over whether bitcoin miners can successfully finance and build the large-scale data centers required to support artificial intelligence (AI) and high-performance computing (HPC) workloads. VanEck estimates the sector faces a near-term funding shortfall of approximately $50 billion, while long-term capital requirements could reach $221 billion if current expansion plans move forward.

VanEck analysts Griffin MacMaster and Matthew Sigel noted that investors are shifting their focus away from headline-grabbing AI partnership announcements and toward actual project delivery. According to the report, the industry has so far deployed only about 25% of the AI and HPC capacity it has contracted. Companies that fail to meet construction deadlines could face significant valuation pressure as investors demand proof of execution.

The transformation of the bitcoin mining industry accelerated after the 2024 Bitcoin halving reduced mining profitability. In response, many miners began leveraging their existing power infrastructure to serve AI companies, which generally offer higher returns for power and data center capacity than traditional cryptocurrency mining operations.

Several major players have embraced the trend. Core Scientific secured a multibillion-dollar hosting agreement with AI firm CoreWeave, while TeraWulf, Hut 8, Iren, and Cipher Mining have announced plans to provide AI and HPC infrastructure services. Meanwhile, Marathon Digital, Riot Platforms, and CleanSpark continue to pursue hybrid strategies that combine bitcoin mining with AI-related opportunities.

The AI narrative has fueled strong stock performance across the mining sector. Riot Platforms has gained roughly 94% year-to-date, while Cipher Mining has risen about 62%. Investors increasingly value these companies based on their AI growth potential rather than their traditional mining businesses.

VanEck believes “energized power,” or operational power capacity, remains the most reliable valuation metric. Companies with signed AI contracts often trade at valuation multiples exceeding 10 times energized power, while firms still marketing future projects receive lower valuations. The report also suggests that miners serving investment-grade hyperscale customers may benefit from lower financing costs and stronger market premiums.

Looking ahead, VanEck identifies HIVE, Bitdeer, Keel, and IREN as potential beneficiaries if they secure additional AI contracts. In contrast, Marathon Digital, CleanSpark, and Riot Platforms remain more closely tied to bitcoin price movements.

Ultimately, VanEck argues that the next phase of the AI infrastructure boom will be defined not by ambitious announcements but by the ability to finance, build, and operate large-scale data centers efficiently. Companies that successfully convert leased power capacity into functioning AI facilities on schedule and within budget are expected to emerge as the sector’s long-term winners.
