Definitions

Event contract

A contract whose value follows a defined event, such as an election. It settles on the outcome. It does not trade a continuous price forever.

Prediction market

A venue where event contracts trade, so their prices express a market-implied probability of the event happening.

Prediction market index

A rules-based benchmark built from selected event contracts. An index provider calculates it, not a venue.
