KALSHI Trading Basics: How to Win on Binary Markets
Kalshi trading refers to buying and selling YES or NO contracts on Kalshi, a CFTC-regulated Designated Contract Market. Each binary market resolves to $1.00 if your side is correct and $0.00 otherwise. Kalshi operates with a central order book and a clearinghouse, and all settlements are in USD. For US-based traders, Kalshi offers a legally regulated venue with clear resolution rules and transparent pricing in cents. This guide explains how Kalshi trading works, what edge looks like in intra-market arbitrage, and how KalshiArb can help you monitor opportunities.
How Kalshi trading works in practice
Kalshi trading centers on binary YES/NO contracts where the sum of the best YES and NO prices typically equals $1.00 at fair value. A YES contract priced at 42 cents and a NO contract priced at 58 cents yields a total of $1.00 if either side resolves true. If YES resolves true you receive $1.00 for the YES side and nothing for NO, with losses limited to the amount paid to buy YES. Kalshi’s design ensures predictable, dollar-denominated settlement, making it straightforward to model potential outcomes. Traders interact through a centralized order book and place either market or limit orders, subject to standard constraints like minimum price increments and anti-self-trade checks.
Intra-market arbitrage opportunities
The core edge on Kalshi trades occurs when the best-ask prices for YES and NO on a single market sum to less than $1.00. In that case you can buy both legs and lock in a risk-defined profit from day one. This is the classic intra-market arb: you pay a total less than $1.00 and stand to gain up to $1.00 on settlement, minus the per-contract fee. Spreads tend to tighten near major events, and muIti-market (combinatorial) opportunities exist when several child markets sit under one event ticker and their combined YES prices leave an exploitable gap. Always factor in the Kalshi fee, which scales with price and contract count.

FAQ
- What is Kalshi trading in simple terms?
- Kalshi trading involves buying YES or NO binary contracts on real-world events. Each contract settles to $1.00 if the prediction is correct and $0.00 if it is not. Prices move in cents, and the overall edge often comes from spreads between YES and NO pricing.
- Are Kalshi contracts binary YES/NO and how do they settle?
- Yes. Each market has a YES and a NO side and settles to $1.00 for the winning side or $0.00 for the losing side, according to a written resolution rule. The settlement is in USD and determined by Kalshi’s market operations, not an external oracle.
- What kind of edge can I expect from Kalshi trading?
- Edge primarily comes from intra-market arbitrage when YES and NO best-ask prices sum to less than $1.00. You can buy both legs to lock in a risk-defined profit, before accounting for fees. Combinatorial edges exist across related child markets under the same event ticker.
