Polymarket investigates suspicious bets placed hours before NYT/Siena polls

Polymarket has opened an investigation into suspicious trading activity that occurred hours before the release of NYT/Siena poll results, examining whether certain bettors may have traded on advance knowledge of the survey's findings. The outcome matters because Polymarket's credibility rests on the assumption that contract prices reflect genuine collective judgment rather than information asymmetries. What to watch next is whether the platform identifies the wallets involved, discloses its findings, and moves to tighten rules around when and how poll data can be accessed.
