A First Shared Stage

The two figures were present at AIFesta 26, an AI industry event, in what constitutes their first documented joint appearance at a formal gathering. Event-related materials and imagery from the occasion show the two in the same official setting.

What Remains Uncertain

While the joint appearance itself is established, the full context of their participation — including the exact nature of their roles at the event — was not fully documented in the materials reviewed. Eleven primary sources were consulted in total, including official event assets and event-day photography.

Bottom Line

The core of the claim — that Lee Haemin and Ha Jungwoo shared an official stage for the first time at AIFesta 26 — holds up against the available evidence, but gaps in documentation leave some aspects open. On balance, the claim is Partly True
