Grayscale has converted its Bitcoin Miners ETF into an AI Compute Fund with new GCPU ticker, reflecting miners' pivot toward GPU hosting and compute services.
Grayscale has repositioned its Bitcoin Miners ETF as an artificial-intelligence infrastructure fund, renaming the former MNRS fund the Grayscale AI Compute ETF under the new ticker GCPU, effective September 22. Rather than simply adding AI companies to an existing mining strategy, the restructuring fundamentally shifts the fund's investment objective toward high-performance computing, data centers, and the power infrastructure supporting artificial intelligence.
The shift reflects a recognized constraint on AI expansion. AI's growth is limited by physical compute availability. Data centers currently operate with just six months of capacity, and new facilities require two to five years to build—a timeline that makes infrastructure investment critical to the industry's continued expansion.
GCPU tracks the Indxx High Performance Computing Index and carries an expense ratio of 0.59%. The fund holds 27 companies on NYSE Arca, with IREN, Hut 8, and Applied Digital among its largest positions, followed by other mining-related names and Nvidia. This composition exposes investors to the growing overlap between digital-asset infrastructure companies and the specialized computing capacity demanded by artificial intelligence. The repositioning does not treat Bitcoin mining and AI data-center operations as interchangeable, however. The two sectors require different hardware, serve distinct customer bases, and operate under different revenue models.
Yet several large mining operators have successfully developed parallel AI-compute businesses, demonstrating the potential for transition. IREN exemplifies this shift. The company reported $4 billion in contracted annualized revenue for 2026 capacity, with AI Cloud Services generating $128.8 million in fiscal 2026 against $578.2 million from Bitcoin mining. Hut 8 is pursuing a similar diversified approach, operating Bitcoin mining infrastructure alongside traditional cloud services and its Highrise AI platform, designed for production-scale model training and deployment. These examples illustrate why companies that originated in crypto mining can remain relevant within a fund focused on high-performance computing infrastructure.
