Why Polymarket Moves Before the News: The Physics of Information Arbitrage
Why prediction markets often react before headlines appear—and what that reveals about incentives, latency, and the future of information discovery.
May 3, 2026
Prediction markets like Polymarket often appear to move before the news.
Not because they predict outcomes.
Because they compress fragmented information faster than editorial systems can serialize it into headlines.
This is not intuition.
It is latency arbitrage in information space.
Core Thesis
Why Markets Move First
Markets do not wait for certainty. They price conditional belief immediately.
Information Flow Model
Market as Sensor Network
Latency Collapse
Latency is no longer human-scale. It is machine-scale inference.
System Comparison
Machine-Readable Reality
Key Insight
Markets are not forecasting tools.
They are continuous inference engines over partial information.
The price is not prediction.
The price is aggregation.
Structural Implication
Price becomes the first draft of reality.
Observe information before it becomes narrative
Track probability movement as the earliest measurable expression of collective belief.
