Google backs TeraWulf’s Lake Mariner AI data center with $3.2 B guarantee and warrants

TeraWulf announced that Google will provide a backstop guarantee of roughly $3.2 billion for Fluidstack’s lease obligations at the Lake Mariner campus in New York. Google also acquired warrants for about 14% of TeraWulf’s equity, equivalent to roughly 73.5 million shares. The company reached 102 MW of revenue‑generating capacity, triggering $600 million of the credit support, and reported $31.9 million of HPC lease revenue in Q2 2026.

The credit guarantee reduces lease‑payment risk for TeraWulf’s AI infrastructure expansion, potentially improving its balance sheet and financing costs. Google’s warrant position aligns a major tech partner’s interests with TeraWulf’s growth, which could influence investor perception of the company’s AI‑focused strategy.
