Market will resolve based on the prevailing interpretation of any existing Trump's comments on catastrophic risks from advanced AI.

"More pessimistic" = Based on his statements, Trump will seem to take AI x-risk more seriously than Biden

"Mixed or unclear position" = it won't be possible to reasonably judge in which direction he positions himself in relation to Biden, e. g. because his statements will be contradictory

"No position" = he doesn't say anything that could be interpreted as a position on the danger of AI x-risk
