Design a Good Market

Write a clear question

• Use specific wording and a single, objective outcome.
• Avoid compound conditions or multiple events in one question.
• State the exact resolution source in the description.

Define resolution criteria

Your description should explain exactly how the market will be resolved. If the resolution is subjective or unverified, the market may be rejected.

Binary resolution rule (classic)

Classic markets are binary. At resolution, the resolver must choose exactly one of two outcomes from objective evidence.

• Outcomes must be mutually exclusive (both cannot be true at the same time).
• Outcomes should cover all cases so one can always be selected.
• Avoid vague wording like “do well”, “big move”, or “soon”.

Description template (copy/paste)

Use this structure in classic markets so users and resolvers read the same decision logic.

Keep outcome terms exactly aligned with your market labels to avoid mismatches.

In the current create flow, these fields are mandatory for classic markets and are appended to the final on-chain description automatically.

Choose the right type

• Classic markets are best for events with fixed deadlines.
• Perpetual markets are best for ongoing states and trends.
