Samsung Puts $1B Into Nvidia and KKR-Backed Helix
3 min readSamsung is buying its way into the AI infrastructure buildout. Samsung Electronics and five of its affiliates will jointly invest $1 billion in Helix Digital Infrastructure, the AI infrastructure company that KKR created and Nvidia backs, according to a CNBC report on September 29. The Samsung Helix investment is Korea’s biggest single move yet into the plumbing behind AI, rather than the chips inside it.
What Helix is
Helix got off the ground in June 2026 as a full-stack AI infrastructure developer. Its remit runs from hyperscale data center development and operations to power generation, transmission and distribution, and the fiber-optic networks that tie sites together. The company is led by Adam Selipsky, the former chief executive of Amazon Web Services.
Its founding investors are KKR, the Kuwait Investment Authority, Nvidia and the US power producer Vistra. Together they had already committed more than $10 billion before Samsung arrived.
How the Samsung Helix investment is split
Samsung Electronics is putting in $500 million. The remaining $500 million is spread across Samsung C&T, Samsung SDS, Samsung SDI, Samsung Life Insurance, and Samsung Fire & Marine Insurance, per The Korea Herald. That roster is telling: it includes a construction arm, an IT services arm, a battery maker and two insurers, which is roughly the set of businesses a data center developer needs as partners.
Samsung is already one of the two dominant suppliers of the high-bandwidth memory that goes into Nvidia’s accelerators. Taking an equity position in a developer that will buy Nvidia systems at gigawatt scale moves the company one step down the chain, from selling components into the buildout to owning a slice of it.
Why it matters
Power and land, not GPUs, have become the binding constraint on AI capacity, and the money is following. Helix is designed to solve that constraint by owning generation and transmission alongside the buildings. Samsung’s cash gives it more room to do so, and gives Samsung a customer relationship with the projects that will consume its memory for years.
For Korea, the deal comes as AI chip demand lifts exports for a sixteenth straight month and as the government pushes a $592 billion domestic memory cluster. The Samsung group is now hedged on both sides of the trade: it makes the chips, and it owns part of where they go. Watch for which sites Helix breaks ground on first, and whether Samsung C&T ends up building them.
