Samsung, affiliates invest $1 billion in KKR's Helix Digital Infrastructure

Helix Digital Infrastructure launched in June as a company built by investment firm KKR, with KKR, the Kuwait Investment Authority, Nvidia and U.S. power company Vistra as founding investors. It is now adding Samsung Electronics and five Samsung affiliates — Samsung C&T, Samsung SDS, Samsung SDI, Samsung Life Insurance and Samsung Fire & Marine Insurance — as backers of a combined $1 billion investment, with Samsung Electronics alone putting in $500 million.

The Samsung group brings capabilities that map onto the different layers Helix says it wants to cover. Samsung Electronics supplies semiconductor solutions and, through its Device eXperience division, data-center cooling equipment from FläktGroup, which it acquired in 2025. Samsung C&T works on data-center and power projects as an engineering, procurement and construction contractor, while Samsung SDS designs and operates data centers and has entered the GPU-as-a-service market. Samsung SDI provides uninterruptible power supplies and battery backup systems and plans to explore further opportunities in the sector.

The outcome is likely to hinge on how quickly Helix can line up power, which the company itself described as a major bottleneck for AI infrastructure. Its plan to secure capacity through direct investment and partnerships with energy developers, including Vistra, is the piece that would determine whether the group's hardware, engineering and cooling capabilities can be deployed at the scale the investment implies.
