Bitcoin mining companies are increasingly shifting their focus towards AI infrastructure, creating new investment opportunities, according to Matthew Sigel, Head of Digital Assets Research at VanEck. Sigel highlighted that mining stocks are currently undervalued compared to other data center peers, despite their strategic pivot to serve the AI market. This transition comes amid grid supply challenges and rising demand shocks. Core Scientific plans to sell most of its bitcoin holdings this year to expand its AI and high-performance computing operations. Riot Platforms is also making a strategic shift, aiming to allocate nearly 2 gigawatts of power capacity to high-demand data center infrastructure by 2025. Over the past year, Core Scientific's stock surged 90%, and Riot's rose 91%, while MARA Holdings saw a 35% decline due to increased mining costs. VanEck's NODE ETF, launched in May last year, has gained over 30%, now holding $56 million in net assets.
