Castle Labs has placed the AI revenue share of Bitcoin (BTC) miners at 22%, according to a report published by COINOTAG on October 13, 2026.

In an update at 08:06 UTC, COINOTAG noted that PRL's market capitalization stood at $475 million at the time of observation, with 339 million tokens mined.

Background

Bitcoin miners have increasingly pursued revenue diversification into artificial intelligence and high-performance computing (HPC) services. Mining economics have tightened as successive halving events reduce block subsidies and growth in global hashrate intensifies competition for block rewards. In response, mining operators have explored ways to monetize existing power resources and data center infrastructure by hosting AI-related workloads.

The 22% figure represents the share of Bitcoin miners' revenue attributed to AI-related activities, as stated in the report. For readers tracking the sector, it provides a quantified reference point for how far this diversification push has progressed, sitting alongside the operational data points included in the same update, such as the market capitalization and mined-token figures noted above.

The measurement arrives as the intersection of mining and AI hosting remains a focal point for observers of the industry's shifting revenue mix. Going forward, updated figures from Castle Labs and COINOTAG, together with mining operators' own disclosures that separate AI and HPC hosting income from traditional mining revenue, offer the most direct way to track how this mix evolves over time.
