TeraWulf announces a major long-term data center lease agreement with Anthropic valued at about $19 billion, prompting a sharp rise in TeraWulf’s stock. According to reports from Yahoo Finance and Channel NewsAsia, the deal centers on providing data center capacity for Anthropic’s computing needs over an extended period. The announcement drives market reaction, with investors buying shares amid expectations that the contract will generate substantial and more predictable revenue for TeraWulf.

The articles frame the lease as a significant development for the company’s data center business and for the broader market for large-scale artificial intelligence infrastructure. While the reports emphasize the headline value of the contract and the immediate share-price jump, they do not provide detailed breakdowns in the excerpts provided regarding lease terms beyond the stated total value, specific site locations, or start dates. Overall, the coverage is consistent that the agreement is large in scale, is tied to Anthropic, and is followed by a noticeable increase in TeraWulf’s trading performance.
