A well-written market question is clear, specific, and objectively verifiable. Ambiguous questions lead to disputes and erode trust in the market. Follow these guidelines to write questions that resolve fairly.
Be specific and unambiguous
Avoid vague language. Anyone reading your question should be able to agree on what a "Yes" or "No" answer means — without interpretation.
❌ Will the company do well this year?
✅ Will Company X report annual revenue above $1 billion for FY2025?
Include a clear timeframe
Always specify when the outcome will be determined. This aligns with your market's end date and prevents ambiguity about which time period applies.
❌ Will Bitcoin reach $100,000?
✅ Will Bitcoin reach $100,000 by 31 December 2025?
Make the outcome objectively verifiable
The outcome should be verifiable using a publicly available source — a news report, official announcement, on-chain data, or a sports result. Avoid outcomes that depend on opinion or interpretation.
Design clear, exhaustive outcomes
For Yes/No markets, make sure the outcomes are truly binary. For multi-outcome markets, ensure the options are mutually exclusive and collectively cover all possible results. If one option can be interpreted as overlapping with another, the market will be harder to resolve.
Write resolution criteria
Use the Resolution criteria field to add context. Specify the source that will be used to verify the outcome and any edge cases (for example, what happens if the event is cancelled or postponed). Good resolution criteria reduce the chance of disputes.
