Prediction markets risk credibility through manipulation

Prediction markets, like Polymarket, face a critical challenge where a single trader can manipulate outcomes, undermining their credibility as accurate predictors of events. This vulnerability arises when contracts create financial incentives for actors to influence the very events they are meant to forecast, turning prediction into execution. The issue is not market volatility but flawed design, particularly in thinly traded or ambiguously resolved contracts. If the cost of interfering with an outcome is lower than the potential payout, the platform incentivizes manipulation rather than genuine prediction.
