How it works on Kalshi

Kalshi's API glossary defines an event as a collection of markets and the basic unit that members interact with on Kalshi. A race, a monthly data release or one day's weather is an event; each candidate, strike or temperature range inside it is a separate market with its own price.

Events sit inside a series, the template for recurring events that follow the same format and rules. In Kalshi's example, the series KXHIGHNY has the event KXHIGHNY-24JAN01, which contains the market KXHIGHNY-24JAN01-T60. The series carries settings such as the fee type and fee multiplier, the event groups the markets for one occurrence, and each market is what you actually buy or sell.

What to check: whether the markets in an event are mutually exclusive (only one can resolve Yes, like candidates for one office) or directional ("above 3.00" and "above 3.10" can both resolve Yes). Kalshi's collateral return rules cover both kinds with different math, and the difference changes how prices across the event add up.

Related terms

• Market: One yes-or-no contract inside a Kalshi event, such as "Above 3.10" in a gas price event, with its own ticker, order book, prices and rules.
• Ticker: The short code Kalshi uses to identify a series, event or market, like KXHIGHNY, KXHIGHNY-24JAN01 and KXHIGHNY-24JAN01-T60.
• Range (bracket) market: A Kalshi event split into brackets, like daily high temperature ranges with "or above" and "or below" ends, where one reading lands in one bracket.
• Strike: The threshold or range a Kalshi market is built on, such as "above 3.10" for gas prices; each strike in an event is its own market.
• Combo (multivariate market): A Kalshi market that bundles several outcomes into one position, priced by request for quote, paying $1 per contract only if every leg wins.
