What if the subject of a prediction market is a matter that is subjective and/or politically charged? Suppose, for instance, the question asked is "Is the Trump presidency a net positive?", or something even more seemingly factual like "Did Hillary Clinton commit a criminal offense?" or "Is there a correlation between race/gender and $desirabletrait?". Not only will reporters' votes likely correlate with their political affiliation, but even the incentive structure is not aligned with producing the truth if we only grant that people assign nonzero monetary value to their tribe's status rising (as would happen if a prediction market agreed with it).
