Mostly True
Nvidia held an 'AI Day' event in Seoul, with some 20 Korean companies — including Samsung Electronics, SK and LG affiliates — taking part, according to the claim as assessed against available reporting.
The gathering brought together major Korean technology groups to engage with Nvidia on AI-related topics. Participation from Samsung, SK and LG group companies underscored the breadth of Korean industry interest in the US chipmaker's AI ecosystem.
Details such as the exact date, venue, agenda and the specific list of participating companies were not fully established in the material reviewed, and some figures around attendance may vary across reports. The claim's core assertion — that Nvidia hosted an AI Day in Seoul with around 20 companies including Samsung, SK and LG — is consistent with the reporting, though secondary particulars remain unconfirmed.
Given that the central facts hold while finer details remain less certain, the claim is judged Mostly True.
