The formalization
SK hynix has disclosed to the U.S. Securities and Exchange Commission the name and leadership composition of its investment arm dedicated to artificial intelligence in the United States: the vehicle will be called Hyaico Corp. The Korea Herald reports. The SEC filing formalizes a project announced last January under the provisional name AI Co.
The chairmanship of the board of directors goes to Chey Tae-won, chairman of SK Group, with the task of overseeing investments of up to $10 billion in the US AI sector. The executive chairmanship goes to Song Hyun-jong, president of SK hynix, who will serve as CEO of Hyaico. Also sitting on the board will be Park Sung-wook, former vice president of SK hynix, Kwak Noh-jung, CEO of SK hynix, and Jung Jae-hun, CEO of SK Telecom.
How the vehicle will operate
Hyaico will operate through Solidigm, SK hynix's US subsidiary active in NAND flash memory, investing in American artificial intelligence companies and infrastructure projects, including so-called AI factories. According to the South Korean newspaper, the investment arm should help SK Group extend its presence beyond memory chips into the broader AI ecosystem, sharing technologies and business opportunities with affiliates.
Financing will take place through capital calls: SK hynix and the other investors will contribute funds as investment opportunities arise. The $10 billion ceiling therefore indicates a maximum potential commitment, not a sum already allocated or invested. SK hynix also intends to keep returns from Solidigm's existing memory business separate from new AI investments: dividends and profits from the NAND business should return to shareholders. The company did not specify how returns will be distributed. An SK hynix official told the publication that Hyaico will be managed with investments and profits clearly separated.
Why it matters and what is missing
The change from the January announcement is twofold: the vehicle now has a definitive name and explicit governance, with representation at the top from both the group and its semiconductor and telecommunications subsidiaries. This composition, according to the source's interpretation, signals SK Group's intention to coordinate AI investments across the conglomerate's various businesses, rather than leaving them to individual units.
Several elements remain to be clarified, however. The material does not indicate a timeline for the first investments, nor which companies or infrastructure projects have already been identified. It does not specify how many resources have already been drawn down through capital calls, nor how the separation between NAND profits and AI returns will work in practice for shareholders. On the regulatory front, the source reports only the filing with the SEC and does not mention any additional authorizations that may be required. This is therefore a transaction whose structure and leadership have been formalized, but whose timing and actual recipients of the capital have yet to be defined.
