KraftonUnknown Worlds Trial Closes With CEO’s ChatGPT Use Acknowledged and Founder’s Memo Entered Into Evidence

The case now moves to post-trial briefing with arguments scheduled for January 9.

Overview

  • Krafton CEO Kim Chang-han testified he searched ChatGPT for faster answers on the company’s rights regarding Subnautica 2, likening it to using a search engine.
  • Kim acknowledged deleting some chatbot conversations, saying he was concerned OpenAI could use sensitive company information for learning, as plaintiffs press for the missing logs.
  • A June message from Kim to a Krafton executive referenced ChatGPT indicating it would be difficult to cancel the earnout tied to Unknown Worlds’ deal.
  • A founder-authored 'Litigation Help' document with disparaging remarks about Korea was introduced; Charlie Cleveland confirmed authorship but said the statements reflected others’ views he transcribed.
  • Krafton argues former leaders neglected Subnautica 2 and justified their removal, while the plaintiffs allege deliberate interference to avoid a $250 million earnout and cite a 'secret task force.'
