Bitcoin Miners Shift to AI Amid Declining Difficulty

Bitcoin's mining difficulty has seen significant fluctuations over the past year, influenced by falling bitcoin prices and hash rate migration. In July, it dropped approximately 5%, marking a 20% decline since November 2025.

Major mining companies are increasingly adopting artificial intelligence infrastructure to boost profitability, with several firms announcing significant deals in recent weeks. TeraWulf signed a 20-year lease with Anthropic for a dedicated AI facility in Kentucky, expected to yield around $19 billion in revenue.

Hut 8 also announced the full commercialization of its Texas AI data center, with a contract value of $19.6 billion and an expanded capacity of 704 megawatts.
