Resolution source
The document, oracle, official dataset, or event source used to decide whether a market resolves Yes or No.
Glossary
Prediction-market terms without the noise.
A compact glossary for users comparing event platforms, market wording, resolution sources and custody models.
Access, licences, and settlement
Terms that decide whether you can open an account and how a contract pays out. Confirm operators on CFTC DCM filings and the UK Gambling Commission public register — these definitions are not legal advice.
Event contract
A regulated contract that pays based on a specified event outcome, common in some US-facing venues.
Oracle
A data or resolution mechanism that brings external information into a market or smart contract.
KYC
Know-your-customer identity checks. Requirements vary by platform, region, product, and payment rail.
No-KYC
A shorthand for lower identity friction, not a guarantee. Always check eligibility and platform terms.
Settlement risk
The risk that a market resolves later, differently, or more ambiguously than a user expected.
Trading mechanics
How orders match, how prices move, and how wording changes risk. Fee numbers live on each platform review, not in this glossary.
Liquidity
How much size can be traded without moving price too much. Low liquidity can make entry and exit difficult.
On-chain market
A prediction market where positions, settlement, or collateral interact with blockchain contracts.
Market wording
The exact text defining an outcome. Tiny wording differences can change the practical risk of a position.
Order book
A trading interface where users place bids and asks rather than only buying from an automated curve.
AMM
Automated market maker. Prices adjust through a formula or pool rather than a classic order book.
Slippage
The difference between expected and executed price, often worse in low-liquidity markets.
