Public Bitcoin miners are allocating billions of dollars to artificial intelligence and high-performance computing (HPC) operations, though returns have yet to match the scale of upfront investments, according to data from BlocksBridge Consulting.
In its Miner Weekly newsletter, BlocksBridge reported that a group of 15 Bitcoin miners and AI data-center companies spent a combined $30.7 billion on capital assets in their latest 2026 reporting periods. This figure is 42.6% higher than the $21.53 billion the group spent throughout the entirety of 2025.
For Bitcoin miners specifically, the discrepancy between capital expenditures and generated AI revenue remains wide. Nine comparable miners spent $5.11 billion on capital assets during the first half of 2026, while generating only $341.2 million in directly reported AI and HPC revenue, resulting in roughly a 15-to-1 capex-to-revenue ratio.
BlocksBridge determined capital spending metrics using cash purchases and allocations toward hardware, property, equipment, and other productive assets, adjusted for proceeds and refunds from asset sales.
Despite the wide gap, reported AI and HPC revenue is accelerating. The nine tracked miners generated $205.8 million from those specific business segments in the second quarter, marking a 52% increase quarter-on-quarter. Companies including Core Scientific, TeraWulf, and Bitdeer reported gains during this period.
Industry analysts note that while power contracts and available land provide miners with an initial advantage, converting those assets into functional AI capacity involves heavy investments in substations, buildings, cooling systems, networking equipment, and graphical processing units (GPUs).
The broader financial shift toward digital infrastructure is also reflected in traditional financial products. CoinShares announced a strategy change for its industry-tracking exchange-traded fund, rebranding it as the CoinShares Bitcoin Mining and Digital Power ETF (WGMI). With $222.4 million in assets under management, the fund now includes 29 holdings spanning Bitcoin miners, data center operators, AI semiconductors, power generation, and HPC businesses.
