$1.5 Billion Unplugged: Bitcoin Miners Abandon Hardware Amid AI Pivot

Bitcoin's network has seen a significant shift in recent months, with many public miners shedding their mining capacity and redirecting power towards AI infrastructure. According to data, this 'great unplug' carries an estimated $1.5 billion price tag in equivalent hardware investment, assuming an acquisition price of just $20 per terahash (TH/s). This figure only accounts for the actual machines, excluding buildings, electrical equipment, cooling, and installation costs.

As miners transition to AI, they are not only writing off their existing mining capacity but also continuing to pay interest on debts tied to these sites. TeraWulf generated $53 million in HPC leasing revenue during the first half of 2026 while paying $131 million in cash interest across the company. This highlights the gap between revenue ramp and financing costs.

The shift towards AI is not without challenges, as communities are demanding more control over data centers' electricity demand, water use, and effects on household bills. Existing mining sites may become more valuable where they offer usable power access, but conversions still need to satisfy technical requirements and obtain applicable approvals.
