This doesn't make any sense…

If you want to bet on a binary outcome without knowing how much other participants are betting on the 2 possible outcomes, that's a bookie, not a prediction market.

The entire rationale for claiming that prediction markets "aren't just gambling" and have a legitimate social value is that they surface sentiment and valuation in a transparent and credible way.

(And that's even before we get to the fact that any kind of betting dependent on journalistic work could incentivize outcomes like the death threats reported here.)
