KALSHI Event Contracts: a Trader’S Guide
Kalshi event contracts are binary, USD-settled bets on real-world outcomes, regulated by the CFTC as a Designated Contract Market. Traders buy YES or NO shares, each contract paying $1.00 if the event resolves true and $0.00 otherwise. The pricing of YES and NO legs must sum to $1.00 in fair value, which creates potential edge opportunities for two-sided arbitrage when margins allow. This guide explains how these contracts work in practice and how KalshiArb helps you monitor and act on intramarket edges involving Kalshi event contracts.
What are Kalshi event contracts
Kalshi event contracts are standardized binary instruments on real-world outcomes. Each market has a designated resolution rule and a source for settlement, and outcomes are determined by Kalshi market operations rather than external oracles. Every contract has a YES side and a NO side, with prices that lie between 0.01 and 0.99 dollars. The sum of the YES and NO prices across a given market reflects the market’s view of the probability of the event occurring, with the potential payoff capped at $1.00. For US residents, these contracts are traded on a CFTC-regulated platform and settled in USD.
How Kalshi event contracts work for traders
Traders place limit or market orders on the Kalshi order book, balancing risk and reward. A key rule is that the best-ask prices for YES and NO should sum to $1.00 in fair value; if they don’t, there can be an intra-market edge. The contract dollar size is one unit of risk, priced between $0.01 and $0.99, and the maximum payoff remains $1.00. When a contract resolves, winners are paid $1.00 per winning contract and losers receive $0.00, with settlement handled by Kalshi Klear. Transactions occur in USD, not crypto, and withdrawals move via ACH or supported rails.
Why Kalshi event contracts attract arbitrage traders
Arb opportunities arise when there are pricing inefficiencies within an event or across mutually exclusive child markets under the same event ticker. For example, if a set of related markets collectively offer a net edge where the sum of child YES prices is less than $1.00, buying a complete set can lock in a risk-defined profit. The platform’s binary structure and fixed $1.00 payoff make these edge trades sensitive to timing, liquidity, and fee structure.

FAQ
- What makes Kalshi event contracts different from other prediction markets?
- Kalshi is CFTC-regulated and operates as a US-legal DCM. Settlements are USD-based and rely on explicit resolution rules rather than external oracles. This structure supports regulated trading for US residents.
- How do YES and NO prices create an edge in Kalshi event contracts?
- Since YES and NO prices must sum to $1.00 in fair value, any mispricing where best asks don’t total $1.00 offers a potential arbitrage edge. Traders can sometimes buy both sides to lock in a small, risk-defined profit, subject to fees.
