If it is revealed that an artificial intelligence was elected to public office, this market solves to YES. I will rely on evidence from the major news outlets. If an AI elected but the public doesn't know, the market nonetheless solves to YES (e.g: the face is just someone that speakes whatever the AI tells him to say)

I won't bet on this market and I will hold a low bar for what it would mean, but nonetheless relying in the mainstream media.
