Each month, Gallup publishes a poll asking Americans "what do you think is the most important problem facing the country today?" If Gallup no longer conducts this poll (or an extremely similar one) in 2028, this market will resolve to N/A.
Otherwise, I will find the average (over the 12 months of 2028) of the displayed percentages for the category most specifically referencing abortion and the category most specifically referencing AI. For the current poll, I would consider the category "advancements of computers/technology" to be referencing AI. However, if there was an explicit "AI" option I would use that one instead.

@pietrokc It's a free response. Not sure how they decide what categories to use but there has traditionally been an "advancement of computers/technology" category that was <0.5% until recently.
