Bitcoin miners have contracted 6 gigawatts of power capacity to AI firms across 17 deals valued at more than $110 billion, Bernstein said. The brokerage had estimated the market at $90 billion tied to 3.7 gigawatts in May, indicating a sharp increase in both the scale and value of miner-to-AI agreements. Bernstein said the transactions represent about 10% of U.S. AI data centers under construction, underscoring how miners are increasingly repurposing power access and infrastructure for AI computing demand.
