Key Concepts Explained
Gap Risk
Gap Risk
The risk that prices will “gap” — jump instantaneously without passing through intermediate prices. In prediction markets, this happens at resolution when prices snap from any probability to either 0% or 100%. Traditional liquidation mechanisms can’t protect against gaps because there’s no time to execute.
Time-Boxed Positions
Time-Boxed Positions
Positions that have a predetermined close date before the underlying event resolves. This architectural choice eliminates gap risk by ensuring all positions are closed while markets are still trading continuously.
Health
