AI might gain consciousness. AI might aquire human-like intelligence. AI intelligence might grow exponentially. And finally, AI might think that cows are an existential threat to themselves or that it would be better off without cows and wipe them all out.

If cows are still around on Jan 1, 2030 this market resolves to NO, even if the AI(s) did wipe out all bulls (this market is only about cows).

If cows are not around but AI(s) are then this market resolves to YES if there's certainty that it was AI(s) that wiped them all out. I'll leave the market unresolved until a consensus is reached and if there's no certainty I'll resolve it N/A.

If cows wipe out AI(s) I'll create a follow up market titled "Will cows wipe out humanity before the year 2031?"

If humanity is not around on market close this market does not resolve.
