Grayscale Rebrands Bitcoin Miners ETF Amid AI Computing Shift

Grayscale is making a major change to one of its crypto-focused investment products, repositioning its Bitcoin Miners ETF into a fund targeting the rapidly growing artificial intelligence (AI) and high-performance computing sector.

The Grayscale Bitcoin Miners ETF (MNRS) is expected to be renamed the Grayscale AI Compute ETF on or around September 15, 2026. The fund’s underlying benchmark, the Indxx Bitcoin Miners Index, is also expected to change its name to the Indxx High Performance Computing Index.

The move represents a significant change in strategy. Instead of primarily tracking companies tied to Bitcoin mining, the fund will focus on businesses involved in the infrastructure needed to support AI development, including data centers, computing hardware and other high-performance technologies.

MNRS launched in January 2025 as a way for investors to gain exposure to Bitcoin mining companies and the broader mining ecosystem. Its holdings included major industry names such as Marathon Digital, Riot Platforms and Core Scientific.

Why Miners Are Betting on AI

The shift comes as several Bitcoin mining companies look beyond cryptocurrency. Some miners have been expanding into AI and high-performance computing, using existing advantages such as large-scale data centers, energy infrastructure and access to specialized equipment. 

Companies including Riot Platforms and Marathon Digital have explored opportunities to provide computing capacity for AI workloads as demand for data center resources grows.

Grayscale’s decision reflects a broader convergence between the crypto and artificial intelligence industries. Bitcoin mining companies are increasingly positioning themselves as digital infrastructure providers, while AI companies face growing demand for computing power.
