About
Probiful is a play-money prediction market for healthcare-related questions. It’s a place to stay informed, discuss insights and developments, and express preferences (including willingness-to-pay) in a structured way.
Play money only
Probiful uses credits. There are no deposits, withdrawals, or real-money transactions.
How markets work
Each market is a binary YES/NO question with clear resolution criteria.
- The price (e.g. 63¢) is the implied probability (63%).
- You can buy YES or NO with credits.
- Markets lock at their lock time, then settle after resolution.
Resolution & sources
Markets are resolved by admins using the published resolution rules and cited sources. If a market can’t be fairly resolved, it may be voided and stakes refunded.
