Samsung Electronics and five of its affiliates will invest a combined $1 billion in Helix Digital Infrastructure, the AI infrastructure company set up by investment firm KKR, in a move the South Korean group says will secure access to large-scale data centre and power capacity for its sprawling businesses.

Samsung Electronics itself will contribute $500 million, with the remaining half coming from Samsung C&T, Samsung SDS, Samsung SDI, Samsung Life Insurance, and Samsung Fire and Marine Insurance. The commitment adds to the $10 billion in capital Helix secured from founding investors when it launched in June.

Those founding investors include KKR, the Kuwait Investment Authority, Nvidia and US power company Vistra. Helix is led by former AWS chief executive Adam Selipsky.

Full-stack pitch

Helix positions itself as an integrated infrastructure provider spanning the entire AI value chain. Its scope covers hyperscale data centre development and operations, power generation, transmission and distribution infrastructure, and fibre networks.

The company claims it can help hyperscalers rapidly secure the large-scale, comprehensive infrastructure they need to keep pace with growing AI compute demands. That claim, like much of the emerging AI infrastructure market, remains to be tested against delivery timelines for data centres and the power capacity they require — the two constraints most frequently cited by cloud operators and chipmakers.

Strategic logic

Samsung framed the investment as a way to ensure its affiliates can access a company with interests in areas where they already operate: semiconductors, construction, data centres, cloud computing and finance. The portfolio match is straightforward. Samsung Electronics builds AI chips and memory, Samsung C&T handles construction and engineering, Samsung SDS runs IT services and cloud operations, while the insurance and battery affiliates bring financing and energy-adjacent exposure.

The group also signalled a broader ambition. Samsung said it is poised to expand its role from a traditional hardware component supplier to an "active architect of the global AI infrastructure ecosystem" — language that reflects the vendor's effort to move up the value chain as AI spending shifts from chips and servers toward the data centres and power systems that house them.

Context

The deal lands amid a wave of capital flowing into AI infrastructure ventures, as hyperscalers and investors race to lock in data centre capacity, electricity supply and fibre connectivity. Helix's integrated model — combining power generation, grid infrastructure, fibre and data centres under one roof — is a response to the bottleneck that power availability now represents for AI buildouts in major markets.

For Samsung, the $1 billion commitment deepens its exposure to AI demand beyond its memory and foundry businesses, tying its fortunes to the infrastructure layer that Nvidia, its fellow Helix investor, depends on for continued GPU deployment.

With Selipsky at the helm and an initial $10 billion capital base now swollen by Samsung's contribution, Helix is expected to move from launch-phase pledges to concrete project announcements as it scales its hyperscale data centre pipeline.
