Market resolution rules
By YesNo.fans editorial team · Updated
Good resolution rules make a market tradable. They define what counts, which source is binding, and how edge cases are handled after the market closes.
Every market needs a clear question
A strong market uses plain language, a measurable outcome, a deadline, and a reliable evidence source. Ambiguous markets are harder to moderate and harder to settle fairly.
Canonical English rules are binding
Localized titles and UI text can help discovery, but the canonical English description and resolution rules decide the final outcome on YesNo.fans.
What creators should include
Creators should include the deadline, timezone, final source, any exceptions, and what happens if the event is cancelled, delayed, or impossible to verify.
- Use public, stable sources when possible.
- Avoid subjective wording that cannot be checked.
- Do not change the rules after trading starts.
What resolved markets show
A resolved market keeps its question, rules, final outcome, and close date on its page, so anyone can compare the result with the rules that applied at the time.
