Event-contract data and traditional market data
A factual comparison of prediction-market data and traditional market data. It covers how event-contract data can be organized.
Different underlying instruments
Traditional market-data vendors generally organize around instruments such as equities, fixed income, foreign exchange, and commodities. Event-contract data describes contracts whose outcomes are tied to a defined event. The contract, event wording, venue rules, and resolution process are therefore part of the data context.
Different analytical questions
Traditional feeds often center on prices, trades, quotes, and reference data for financial instruments. Event-contract analysis also requires market questions, outcomes, expiration, settlement state, and the relationship between contracts that describe a common event.
Where Adjacent fits
Adjacent provides public market and index surfaces for event-contract data, including indices, reference rates, market detail, and governance documents. Its indices aggregate selected event contracts according to per-index rules rather than presenting a generic traditional-asset benchmark.
Terms used on this page
- 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.
