That's a fair statement. So this article talks about the Challenger disaster and how the market did reveal the exact corporation that supplied the part and hid it's lack of safety features. In terms of time, the prediction market being available is usually faster before the information flows through the general market in stock prices. There's signals there, but it's much slower and harder to delineate event information from general business performance.
Again, after 20 years of the US government lying to the public about the Iraq and Afghanistan wars, I kind of think you probably *want* insiders revealing information to the public about this administrations military actions in a place like Nigeria. I'm not sure how anyone could think this is bad besides poo pooing someone made money. Prediction markets are an engine to incentivize people to reveal information privately, so I'm not sure how one would whistleblow more efficiently than this.
