This market resolves YES if, before April 2, 2026, PT timezone, Anthropic makes an official public statement confirming that the leak occurred.

The format of the statement does not matter. It may be a tweet, blog post, YouTube video, press statement, or any other public communication, as long as it is clearly an official confirmation from Anthropic and leaves no reasonable doubt that the company is acknowledging the leak.

This market will resolve YES shortly after such confirmation is made.
