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:

​
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.

​
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.

​
Slugs

Each event has a slug that appears in its URL:

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.
