You Saw a Sudden Price Spike. Here's What Actually Happened.
Four things cause sudden moves in prediction markets. Only one of them is suspicious.
The 4 Causes of Sudden Price Spikes
Speed / Attention Advantage
Someone read the same headline you did, 30 seconds earlier.
Algorithmic / Latency Advantage
Machines reacting faster than humans can on public data.
Thin Liquidity / Whale Order
One large order in a low-volume market looks dramatic. Small pool = big price moves for the same dollar amount. Not suspicious — structural.
Material Non-Public Information (MNPI)
Trading on private information obtained in breach of duty.
How to Tell the Difference — 5 Questions to Ask
When Spikes Were Insider Trading (And When They Weren't)
What You Can't Know From a Chart Alone
Most spikes will never be formally investigated. That doesn't mean they were insider trading — it means the evidence bar is high, and regulators focus on confirmed MNPI with a clear subject. The Iran market spike is widely discussed. It has resulted in an ongoing on-chain investigation but no formal CFTC enforcement action as of April 2026. Absence of a case does not equal absence of wrongdoing. It also does not equal proof of wrongdoing. The chart alone cannot tell you which it is.
