Nvidia, Rebellions and SK Telecom Join Forces on Sovereign AI Push in Korea

Nvidia, SK Telecom and Korean chip startup Rebellions will jointly build sovereign AI infrastructure, with Nvidia's NVLink Fusion as the glue holding it together. The interconnect lets third-party accelerators run inside Nvidia's ecosystem rather than beside it. For South Korea, the stated aim is simple: less dependence on technology from outside the country, built on the two industries it already dominates — semiconductors and telecom.

SK Telecom plans a gigawatt-scale AI factory in Korea on Nvidia's DSX AI Factory architecture, targeting operations in 2027. The buildout starts on Nvidia's Blackwell platform and then shifts to the upcoming Vera Rubin platforms. That handoff ties SK Telecom's schedule directly to Nvidia's product cadence.

Rebellions isn't waiting on the factory. Its ATOM-Max NPUs — chips built specifically for AI tasks — already run inside several SK Telecom services. As of September 2026, they were handling roughly 14 million requests and more than 4 billion tokens a day, powering call summarization, text-to-speech and AI-driven contact centers. For Rebellions, that daily load inside a major carrier is a serious credential.

The groundwork has been stacking up all year. In April 2026, SK Telecom, Rebellions and Arm signed an MOU for a joint AI inference server pairing Arm's CPU infrastructure with Rebellions' proprietary tech. July 2026 brought a wider Nvidia and SK Group relationship that could carry an investment commitment of more than $500 billion, spanning AI factories and next-generation memory through SK hynix. Then in August 2026, Nvidia and Rebellions held early-stage talks about possible technical and investment collaboration.

The division of labor suits SK Group neatly: SK Telecom runs the services and plans the factory, SK hynix handles memory, Rebellions supplies domestic inference chips, and Nvidia and Arm fill in the rest. Nvidia keeps its architecture, platforms and interconnect at the center even when the accelerator isn't its own. Worth noting — the $500 billion-plus figure is a potential commitment, not a signed check; the April deal is an MOU stating intent, the Nvidia-Rebellions talks were explicitly early-stage, and the gigawatt factory is a 2027 target, not a finished building.
