Information manipulation in prediction markets is far from fiction—it's happening now. Here's a real case: someone placed a bet on whether a specific territory controlled a certain location. An authoritative source published a map correction. The bet got settled based on that update. Then? The correction simply vanished minutes later. This isn't accidental. It's a clear illustration of how prediction market participants can exploit information asymmetries and rapid corrections to trigger unfavorable resolutions. The speed matters. By the time most traders notice and react, the damage is done. This raises hard questions about data integrity, timestamp verification, and whether current mechanisms can actually protect market participants from sophisticated manipulation tactics. If critical information can be published, acted upon, then erased that quickly, what does settlement reliability really mean?
