KALSHI: a Practical Guide to the KALSHI Platform
Kalshi is a US-regulated platform for trading binary event contracts. It operates under a CFTC license as a Designated Contract Market and settles in USD. Each contract pays out $1.00 on a correct YES or NO resolution and $0.00 otherwise. Traders place YES or NO bids and asks, with price ranges expressed in cents, and KalshiKlear handles clearing and settlement. This article explains how the Kalshi platform works and how KalshiArb fits into that ecosystem for intra-market arbitrage.
How Kalshi works as a US-regulated platform
Kalshi provides a centralized order book for event contracts that are governed by written resolution rules and official data sources. The platform is designed for U.S. residents who meet KYC requirements and want to trade binary outcomes such as political, economic, or weather events. Prices are quoted in cents, and every contract settles to $1.00 if the outcome is true and $0.00 if false.
Trading is done in two sides per market: YES and NO. The best-ask prices for YES and NO must sum to $1.00 in fair value, and traders can use limit or market orders. Kalshi uses a clearinghouse process via Kalshi Klear to finalize settlements after outcomes are determined by the predefined rule.
Understanding YES/NO contracts and settlement
Each Kalshi market has a YES side and a NO side. If you buy YES at, for example, 42 cents and the event resolves true, you receive $1.00 per contract; if false, you lose the 42 cents. The NO side mirrors this logic, with payouts tied to the opposite outcome. The total price range for any contract is constrained between $0.01 and $0.99, ensuring no trade is settled at $0 or $1 directly.
Settlement depends on the official rule source (like a BLS release, court ruling, or tally) and is carried out by Kalshi market operations, not an external oracle. Withdrawals and fiat settlements are handled via traditional rails (ACH or debit), and there is no on-chain settlement.
Arbitrage ideas within Kalshi markets
A key edge is intra-market arbitrage: when the best ask for YES plus the best ask for NO is less than $1.00, you can buy both legs and lock in a risk-defined spread. This is the core idea behind KalshiArb’s intra-market approach. In addition, some events bundle several mutually exclusive markets under one event ticker; if the sum of child YES prices is under $1.00, a complete set of child YES contracts can offer a clean spread.
As markets near resolution, some traders explore endgame yields by purchasing YES positions priced near $1.00, though this carries race-to-settlement risk and other caveats. It’s important to understand that these opportunities are not risk-free and depend on timing, liquidity, and the official resolution.

FAQ
- What makes Kalshi a CFTC-regulated platform?
- Kalshi operates as a Designated Contract Market (DCM) under CFTC oversight. This means prices are quoted in USD, contracts settle to $1 or $0 based on predefined resolution rules, and users must meet KYC requirements to trade.
- How do YES/NO contracts pay out on Kalshi?
- Each contract has two sides: YES and NO. If the event resolves true, the YES side pays $1.00 per contract and the NO pays $0. If the event resolves false, the opposite occurs. Payouts are realized in USD.
- What is the edge for intramarket arbitrage on Kalshi?
- If the best ASK for YES plus the best ASK for NO is less than $1.00, you can buy both sides and lock in a risk-defined spread, minus standard per-contract fees. This is the core intra-market edge KalshiArb targets.
- What should I know about settlement timing and fees?
- Settlements follow Kalshi’s rule sources and are priced in cents. There is a per-contract trading fee that varies with price, and there are no maker rebates. Withdrawals use fiat rails like ACH or debit cards.
