Shares of TeraWulf ( WULF ) jumped 22% on Tuesday after the bitcoin mining firm unveiled a new $9.5 billion artificial intelligence (AI) infrastructure joint venture with cloud platform Fluidstack, deepening its push into high-performance computing (HPC).

The 25-year lease agreement, representing about $9.5 billion in contracted revenue, will see the two firms build out 168 megawatts (MW) of data center capacity at TeraWulf’s Abernathy, Texas campus. The facility will serve AI workloads, and is expected to go live in the second half of next year.

Google ( GOOG ) is supporting the deal by backing $1.3 billion of Fluidstack’s long-term lease obligations, giving lenders more confidence to finance the project. TeraWulf ( WULF ) will hold a 51% stake in the joint venture.

TeraWulf ( WULF ) also secured the exclusive right to co-develop Fluidstack’s next 168 MW AI data center project under similar terms. With this deal, TeraWulf ( WULF ) now has 510 MW of computing capacity under contract, and is aiming to add 250 to 500 MW annually going forward.

In a separate update, the company said it expects third quarter 2025 revenue between $48 million and $52 million, up around 84% from the same period last year. Adjusted EBITDA is projected between $15 million and $19 million, nearly triple last year’s results.
