AI is placing unprecedented pressure on Bitcoin mining profitability, particularly at large-scale sites where energy and real estate costs are high. The significant downward adjustments in Bitcoin mining difficulty during February 2026—recorded at 11.16% and 10.09%—indicate a massive exodus of miners who can no longer justify operational costs. As data center operators realize higher margins by hosting AI hardware rather than Bitcoin ASICs, the mining sector is facing a structural displacement that favors high-performance computing over cryptographic hashing.
The network hashrate, which peaked above 1.1 ZH/s in October 2025, has since retreated toward the 900 EH/s level multiple times. This decline is not merely a result of Bitcoin price volatility but a strategic pivot by infrastructure providers. Many US-based mining firms are retrofitting their facilities to accommodate the power-hungry GPUs required for Large Language Model training, which currently commands a significant premium over the revenue generated per terahash in Bitcoin mining.
From a regulatory and geopolitical perspective, the US energy grid is becoming a central point of contention. As AI is prioritized as a strategic national asset, Bitcoin miners are facing increased scrutiny regarding their electricity consumption and carbon footprints. In some jurisdictions, miners are being outbid for power contracts by tech giants seeking to secure the massive energy loads needed for next-generation AI clusters, effectively pricing mining out of the domestic market.
Investors and industry observers should closely monitor the 'hashprice'—the expected value of 1 TH/s of hashing power—and the frequency of facility conversions from BTC mining to AI hosting. If the hashrate continues to stabilize at lower levels while difficulty drops, it may signal a new era of consolidation. Only the most vertically integrated mining companies with proprietary energy sources will likely survive, while the rest of the industry may be forced to transition into the burgeoning AI service sector to remain solvent.
