AI does not participate in final settlement
01 / Context
Problem
ArcPredict follows a prediction market from opening and participation through outcome proposal, challenge or confirmation, and claim, clarifying the boundary between probability, disputes, and final settlement.
Boundaries
- AI does not participate in final settlement; it only helps explain markets, risks, and states.
- Market and probability data are shown in a demo or testnet context and are not investment advice.
- Claim eligibility depends on the external project contracts and deployment state.
