South Korea's Samsung Group said it will invest a combined $1 billion in Helix Digital Infrastructure, a U.S. AI infrastructure company backed by private equity firm KKR, with Samsung Electronics contributing $500 million and five other affiliates sharing the rest. Helix, launched in June with over $10 billion in committed capital from KKR, Nvidia, Vistra and the Kuwait Investment Authority, aims to tackle power availability, a major bottleneck for data centers and AI computing. Samsung joins as a founding investor and says it will seek synergies between its affiliates' technologies and Helix's business.
