Create a Market

Required fields

• Question: 10-200 characters.
• Background context: 20-1000 characters.
• Outcomes (classic only): 2-50 characters each and must be different.
• Classic criteria (required): Outcome A wins if..., Outcome B wins if...
• Classic criteria (required): one resolution source + one evaluation time (UTC).
• Category selection is required.

Timing

Classic markets require a resolution schedule. The hard minimum is 72 hours between launch and resolution, and trading closes before resolution.

Use Flexible Duration by default. Choose Fixed Date only when the market must resolve at an exact calendar time.

For exact dates, leave enough time for community voting before the market opens.

If community voting takes longer, Flexible Duration can move to a later valid launch window. Fixed Date keeps the calendar time you chose, so pick a later date if the market would otherwise end up too close to resolution.

See Timing rules and Binary resolution rule / Choosing an exact date.

Creator bet

A creator bet is required in WBASED. The minimum creator bet is 420 WBASED. It becomes the first trade at activation. If a market is rejected, the creator bet is forfeited. If it is canceled before activation, the bet is refunded.

Today, the same 2.0% trading fee applies to the creator bet unless a market-specific fee setting is added later. Example: a 420 WBASED creator bet pays 8.4 WBASED in fees and mints shares from the remaining 411.6 WBASED.

On standard markets, the creator also earns the creator share of trading fees after activation. Today that is 25% of each market fee, which equals 0.5% of gross trade size.

Today, the minimum trade size is 0.001 share (`minSharesPerBet = 1e15`), though some market setups may use a different minimum.

For the full fee routing, creator payout examples, and claim flow, see Creator fees and Creator bet and first trade.

Market type

Choose Classic for time-bound events and Perpetual for ongoing questions. Both market types are CPMM-only and use profile templates.

• Classic: slider-based class selection across 24 CPMM classes (10M to 9.0B one-sided cap).
• Perpetual: slider-based isolated class selection across 24 CPMM classes (10M to 9.0B one-sided cap).
• All customer-selectable classes are direct CPMM class templates.
• Creators do not pick curve modules manually; template defaults enforce CPMM.

Quick class rule: set your expected one-sided spend and the slider auto-picks the smallest safe class.

For token translation of class limits, see Class Capacity in WBASED and expand the full class table when you need exact tier values.
