The U.S.-based Bitcoin mining firm TeraWulf is planning to raise $400 million to expand its data center business.

BlockBeats News, August 19th, U.S.-listed Bitcoin mining firm TeraWulf (stock code: WULF) announced plans to raise $400 million through a private placement of convertible senior notes. This financing comes as its AI cloud service customer Fluidstack decided to expand its leasing of 160 megawatts of power capacity at the Lake Mariner campus in New York State.

According to a statement released on Monday, these convertible notes include a $60 million over-allotment option granted to initial buyers, and the proceeds will be used for covered call options trading and the expansion of non-mining data center business. The notes are unsecured senior notes, will bear interest semi-annually starting from March 1, 2026, and will mature on September 1, 2031. Upon shareholder approval, TeraWulf may elect to settle conversions in cash, stock, or a combination thereof. This financing marks TeraWulf's acceleration into the high-performance computing field beyond Bitcoin mining.

Earlier this month, the company entered into two 10-year hosting agreements with AI high-performance computing provider Fluidstack, with Google providing an $1.8 billion leasing guarantee for this and acquiring an 8% stake in TeraWulf.
