# Complete Sets

A complete set is one of every outcome token: in a binary market, 1 YES + 1 NO. A set can always be minted (deposit $1.00, receive one of each) or burned (return one of each, receive $1.00). This creates a hard price anchor.

**Why prices stay honest.** Say YES is trading at $0.70 and NO at $0.35, so the pieces sum to $1.05. Anyone can mint a set for $1.00, sell the two tokens for $1.05, and pocket the spread; the selling pressure drags the prices back toward summing to $1.00. The same logic runs the other direction. You don't have to trust that the numbers add up. The mechanism enforces it.

**Resolution delay.** A market can't resolve the instant it closes, since not every transaction in the window has settled yet. To capture the full picture, there is a 48-hour delay from market close to resolution and payout.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.spend.market/markets/graduation-and-complete-sets/complete-sets.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
