This is naive. The people deciding about the bombing will profit most by taking a very large and unlikely position against the market’s predictions and then carrying it out immediately.

Anonymous trading on prediction markets leads to unpredictable chaos in the end. And as destruction is easier than creation that’s what we will see more of.

Example: a fake German market for train punctuality was announced to make a point recently. If it had been real, train staff and passengers could trivially have profited by betting against any expected punctual train and blocking a door for a few minutes. Or betting against many trains and throwing a hopefully fake body onto a busy line.

Having nice things in society is fragile and not a given. They mostly exist through mutual consent and mild disincentives to destroy the common good. Allow people to profit by destroying them and enough of them will.
