# Markets & Events

> The building blocks of every prediction on CHOK.

Predictions on CHOK are organized into **events** and **markets**. An event is what you see as a card on the home page. A market is a single resolvable question with two outcomes.

## Markets

A **market** is the unit you trade. Each market is one binary condition, such as Yes or No, Up or Down, or two named sides.

Every market has these identifiers:

| Identifier | What it is |
| - | - |
| **Condition ID** | The market's condition in the Conditional Tokens contract |
| **Question ID** | The ID the resolution adapter uses for the question |
| **Token IDs** | Two ERC-1155 token IDs, one for each outcome |

## Events

An **event** groups one or more markets.

### Single-market events

Most events on CHOK contain one market, so the event and the market are the same question.

```
Event: Will it rain in Seoul tomorrow?
└── Market: Will it rain in Seoul tomorrow? (Yes/No)
```

### Multi-outcome events

An event with several mutually exclusive answers is a group of binary markets, one per answer. Exactly one of them resolves Yes. See [Negative Risk Markets](https://docs.chok.market/concepts/negative-risk.md).

```
Event: Who will win the election?
├── Market: Candidate A? (Yes/No)
├── Market: Candidate B? (Yes/No)
└── Market: Candidate C? (Yes/No)
```

## Slugs

Each event has a **slug** that appears in its URL:

```
https://chok.market/event/seoul-rain-tomorrow
                          └── slug
```

## Who creates markets

Markets on CHOK are created by the CHOK team. Users cannot create markets. Each market has:

* A title and outcomes in **English and Korean**. The language follows the site language (`chok.market` for English, `chok.market/ko` for Korean).
* **Rules** that say exactly how the question resolves and which source is used.
* A **category**, such as Economy, Sports or Weather. The CHOK team decides which categories are open.

Market times are shown in **UTC**.
