Six Samsung affiliates are putting a combined USD 1 billion into Helix Digital Infrastructure, an AI infrastructure company founded by KKR and launched in June 2026. The investment was announced by Samsung Electronics today. Helix is led by Adam Selipsky, the former AWS chief executive, and its founding backers include KKR, NVIDIA, Vistra and the Kuwait Investment Authority.
The Samsung entities taking part are Electronics, C&T, SDS, SDI, Life Insurance, and Fire & Marine Insurance. Samsung did not disclose how much each affiliate is contributing, nor when the deal is expected to close. The announcement also leaves out Helix's valuation and any revenue figures, and names no specific data center sites or capacity targets.
Helix is building toward hyperscale data center development and operations, spanning power generation, transmission and distribution, plus fiber networks. It plans to add energy capacity through direct investments and partnerships with developers, with Vistra named as its energy partner. The company is assembling a management team drawn from the data center and power industries. KKR's infrastructure business, which backs the venture, has roughly 170 dedicated professionals.
Samsung's pitch is that it can supply more than components. Its DX Division offers cooling through FläktGroup, a subsidiary Samsung acquired in 2025. Samsung C&T's E&C Group works as an engineering, procurement and construction contractor for data centers and power projects. Samsung SDS designs, builds and runs data centers and has moved into GPU-as-a-service. Samsung SDI supplies uninterruptible power supplies and battery backup units for data centers. The company says it wants to shift from component supplier to AI infrastructure architect.
The move follows Samsung's recent pattern of large-scale bets on computing and chip capacity. In September, Mistral raised a €3 billion Series D led by Samsung Electronics, a round that pushed Mistral's post-money valuation past €21 billion. Earlier in the summer, Samsung and SK Hynix committed $520 billion to build four new fabs outside Seoul, in Gwangju and the wider southwest.
Samsung's own position in the Korean market has shifted at the same time. SK Hynix overtook Samsung as the country's most valuable listed company, ending a run at the top of the KOSPI that Samsung had held since November 2000. SK Hynix's market capitalization stood at 2,080.38 trillion won, or about $1.35 trillion.
