Prediction markets, which have been praised as innovative mechanisms for predicting geopolitical events, are now at risk due to insider trading.
For instance, the dramatic upswing in contracts relating to war on platforms such as Polymarket, contrary to the public revelation of the news, has highlighted the fact that these markets may be operated by individuals with insider knowledge.
The Insider Advantage
After all, plans for military and diplomatic moves are made in very limited circles with almost no leakage of information. In fact, this not only gives an unfair advantage to the insiders but it also enables them to reap benefits from non-public information.
The Pentagon Pizza Index, a somewhat humorous reference to a hint of a forthcoming event, serves as an example of how people instinctively recognize this phenomenon.

Geopolitical Markets
Supporters of sports betting claim that it is evidence that prediction markets can operate smoothly. However, this argument loses its strength when applied to geopolitics.
Wars and political decisions are usually made in secret and only experienced by a limited group of people. Also, the resolution of even contracts can depend on interpretations to such a degree that one doesn’t really know whether proper forecasting or insider trading is taking place.

Developing Equitable Markets
Prediction market platforms need to double down on the design of the markets and incorporate market controls to fight the problem of insider trading.
It means, among other things, that the participants need to be really clear about what counts as inside information, that people who have inside information should not be allowed to trade, that real identity checks should be performed, and that trade patterns which may indicate the presence of an insider trader should always be made subject to further investigation.
Decentralized platforms have to find the right mix between being open and being enforceable and make sure that insider trading is seen as a structural risk rather than an issue of mere bad optics.
