Bitcoin Mining Stocks Rise After TeraWulf Signs $19 Billion Anthropic Lease

TeraWulf has signed a 20-year lease agreement with Anthropic that is expected to generate $19 billion in revenue, according to Decrypt. Following the announcement, major Bitcoin mining stocks jumped.

The development matters because it highlights how Bitcoin mining companies are being watched not only for their crypto exposure, but also for the value of their infrastructure. Large, long-term leasing agreements can reshape how markets assess miners with power access, data center capacity, and related facilities.

For TeraWulf, the Anthropic lease adds a major revenue expectation over a two-decade period. The size and duration of the agreement appear to have drawn investor attention to the broader mining sector.

The move also comes as mining companies look for ways to diversify beyond Bitcoin production alone. While the source does not provide additional operational details, the market reaction suggests investors are weighing the role miners may play in serving high-demand computing customers.

The rally in mining stocks does not change the risks tied to the sector, including sensitivity to crypto market cycles and company-specific execution. But the TeraWulf-Anthropic deal gives the market a fresh example of how mining-linked infrastructure can attract major commercial interest.
