What Are Prediction Markets?
A plain-language primer on event contracts, implied probabilities, and why markets can become useful signals.
The Basic Idea
Prediction markets are markets tied to future events. A contract price can be read as a live estimate of how likely the crowd thinks an outcome is, though that estimate can be noisy, thinly traded, or wrong.
PMN treats those prices as reporting inputs. They are useful because they update quickly and force participants to attach numbers to beliefs.
What Prices Can Tell You
A price move can reveal changing attention, new information, shifting risk appetite, or a liquidity imbalance. The signal is strongest when volume, liquidity, and outside evidence point in the same direction.
The important question is not only what the odds say. It is why the odds moved, who might be better informed, and what evidence would change the market again.
What Prices Cannot Tell You
A market price is not proof that an event will happen. Thin markets can overreact, resolution rules can be awkward, and traders can focus on incentives that ordinary readers do not share.
That is why PMN separates the market signal from the real-world story behind it.
