Cosmos Health, a Nasdaq-listed healthcare group with a market capitalization of about $29 million, said it has arranged up to $300 million in financing through senior secured convertible promissory notes. The company plans to use the facility to build an Ethereum-based treasury, marking one of the largest crypto-linked balance-sheet moves by a small-cap U.S. corporation. Investors welcomed the announcement, sending Cosmos Health shares up roughly 39% intraday. The transaction signals a growing appetite among non-technology companies to hold digital assets as core treasury reserves. The shift comes as traditional finance houses warm to the idea of corporate Ethereum holdings. Standard Chartered said this week that firms running Ethereum treasuries are now "very investable," arguing the strategy can be more attractive than exposure gained through U.S. spot ETH exchange-traded funds.
