DDC Enterprise Limited, a New York Stock Exchange-listed software provider, said it has closed a $528 million financing round aimed at expanding its Bitcoin holdings. The company described the raise as one of the largest single capital injections by a U.S. public company expressly for building a cryptocurrency treasury. Investors in the round include Anson Funds and other institutional backers, according to the company. DDC said the funds provide "immediate capital" to advance a previously announced strategy of converting a portion of its balance-sheet cash into Bitcoin, though it did not specify a purchase timetable. The move underscores renewed corporate interest in Bitcoin after a prolonged downturn in digital-asset prices. DDC joins a small but growing roster of publicly traded firms that view Bitcoin as a long-term store of value alongside traditional reserves.
