Bitcoin Miners Spend Big on AI Infrastructure, But Revenue Still Lags

Bitcoin miners are shifting their focus to artificial intelligence infrastructure, but the revenue generated from this shift is still lagging behind. According to a new analysis by BlocksBridge Consulting, nine public Bitcoin miners spent $5.11 billion on capital assets during the first half of 2026, but only generated $341.2 million in AI and high-performance computing revenue over the same period.

This works out to roughly 15 dollars spent for every dollar of AI revenue collected. The figure covers hardware, property, and equipment purchases, not just AI-related spending alone.

The shift towards AI infrastructure is costly, with miners needing to invest in substations, cooling systems, networking gear, and sometimes GPUs to convert their mining sites into AI-ready facilities. This requires financing well before any tenant starts paying.

Core Scientific is one example of a company that has made significant investments in this area, spending $797.5 million on capital assets in the second quarter while reporting $136.7 million in colocation revenue, up from $77.5 million in the prior quarter.
