Glossary

Prediction-market terms without the noise.

A compact glossary for users comparing event platforms, market wording, resolution sources and custody models.

The document, oracle, official dataset, or event source used to decide whether a market resolves Yes or No.

How much size can be traded without moving price too much. Low liquidity can make entry and exit difficult.

Know-your-customer identity checks. Requirements vary by platform, region, product, and payment rail.

A regulated contract that pays based on a specified event outcome, common in some US-facing venues.

A prediction market where positions, settlement, or collateral interact with blockchain contracts.

A data or resolution mechanism that brings external information into a market or smart contract.

The exact text defining an outcome. Tiny wording differences can change the practical risk of a position.

A trading interface where users place bids and asks rather than only buying from an automated curve.

Automated market maker. Prices adjust through a formula or pool rather than a classic order book.

A shorthand for lower identity friction, not a guarantee. Always check eligibility and platform terms.

The difference between expected and executed price, often worse in low-liquidity markets.

The risk that a market resolves later, differently, or more ambiguously than a user expected.
