SK Telecom AI Cloud: Gigawatt-Scale NVIDIA DSX AI Factory
Status: Active / Early Site Civil Engineering & Technology Blueprint Integration (Tracking June 2026) | Location: Greater Seoul Regional Node, South Korea
Project Overview
The SK Telecom "AI Cloud" Factory is a groundbreaking, gigawatt-scale digital infrastructure initiative officially announced on June 7, 2026. Developed through a high-profile technology alliance between SK Group and NVIDIA, this mega-scale development represents South Korea's most aggressive push to establish absolute autonomy over its national sovereign artificial intelligence processing pipeline. Advancing into localized site engineering, foundation designs, and structural substation integration in mid-2026, the campus transitions away from traditional general-purpose hyperscale designs. Instead, the facility is purpose-built as an "AI Factory" optimized explicitly for accelerated GPU computing, multi-trillion parameter neural network training, and high-throughput agentic AI deployment. Built on the unified NVIDIA DSX full-stack reference architecture, the complex integrates advanced compute nodes directly with SK Group's next-generation high-bandwidth memory (HBM) and telco transport networks. This specialized blueprint maximizes token output while achieving the industry's lowest operational cost per megawatt
