Parlays are markets with **multiple conditions**. While most markets resolve based on a single condition, parlays depend on several linked conditions. Each parlay is made up of **linked markets**. The parlay resolves based on the outcomes of those linked markets. *Example*: In *Nothing Ever Happens: Conspiracy Edition*, the parlay stays open until either: * Any listed condition is met, causing the market to resolve to **No**. * None of the listed conditions is met by December 31, 2025, causing the market to resolve to **Yes**.

### Nothing Ever Happens Nothing Ever Happens parlay markets resolve to **Yes** only if all linked events resolve to **No**. If any event occurs, the market resolves to **No**. The idea behind Nothing Ever Happens markets is that people often **overestimate how many events will actually happen**.

### Everything Happens Everything Happens parlay markets resolve to **Yes** only if all conditions are met. If even one condition fails, the market resolves to **No**. The idea behind these markets is that **all of the linked events will occur**.

### Mixed Parlays Some parlay markets combine conditions across **related or unrelated events**, such as elections, political events, or cultural markets. How they resolve depends on the rules of each linked market.

### Parlay Rules Each linked market follows its own rules to determine whether its condition is met. The parlay then resolves based on the combination of those outcomes.
