Terawulf Inc. said it has expanded its partnership with cloud-services provider Fluidstack, signing a 160-megawatt CB-5 lease at its Lake Mariner site in upstate New York. The additional capacity lifts the bitcoin miner’s contracted power at the location to 360 MW, underpinning $6.7 billion of committed revenue, or as much as $16 billion if all extension options are exercised. Commercial operations at the newly leased facility are targeted for the second half of 2026. As part of the expansion, Google increased a credit backstop for Terawulf to $3.2 billion and obtained warrants for 32.5 million shares that could raise its equity stake in the company to about 14% from 8%. The technology giant’s deeper involvement follows an earlier commitment last week and comes as miners seek reliable power and financing amid volatile cryptocurrency prices. Separately, Terawulf launched a private offering of $400 million in convertible notes maturing in 2031. Proceeds are expected to fund construction at Lake Mariner as well as general corporate purposes.
