Korean AI industry profitability is concentrated in the semiconductor supply chain... Medical AI and autonomous driving are still in the investment stage

An analysis of 80 listed Korean AI companies found revenue and net profit rose sharply from 2023 to 2025, but profitability was concentrated in the semiconductor and materials/supplies supply chain.

LLM and agent businesses kept growing, yet many depended on public-sector and build-to-order projects rather than scalable recurring revenue.

Data center and cloud businesses faced margin pressure from upfront investment costs, while physical AI and robotics remained early-stage.

Medical AI and autonomous driving were still loss-making or back in deficit due to regulatory and certification hurdles.

The results highlight that Korea’s AI profits are coming more from infrastructure and supply chains than from headline-grabbing application themes.
