KALSHI Markets: Understanding Binary Event Contracts
Kalshi markets are US-regulated binary event contracts where each market is settled to $1.00 if a specific outcome occurs, and $0.00 otherwise. Traders buy YES or NO shares in response to real-world events ranging from elections to weather. Kalshi operates as a Designated Contract Market with a centralized clearinghouse, and settlements are in USD when the resolution rule is applied. This guide outlines how those markets function and where arbitrage opportunities commonly arise. It also notes the non-custodial nature of KalshiArb’s tooling and how you can leverage YES/NO pricing within Kalshi markets.
How Kalshi markets work: YES/NO pairs and settlement
Every Kalshi market is binary with YES and NO sides. The YES price plus the NO price should sum to one dollar in fair value. If you buy YES at 42 cents, you stand to gain up to a $0.58 profit if the event resolves true, or lose 42 cents if it resolves false. NO behaves symmetrically. Settlement is in USD: winning contracts pay out $1.00, losing ones pay out $0.00, and the final calculation is based on Kalshi’s written resolution rule, not an external oracle. This framework is what makes intra-market arbitrage and edge detection possible for disciplined traders. Kalshi’s CFTC-regulated status and USD settlement are core distinctions from other platforms.
Pricing dynamics and edges you can exploit
Prices on Kalshi move with event-driven information, liquidity, and trading activity. The tick size is one cent, and min/max prices run from 0.01 to 0.99. A typical edge arises when the best-ask for YES plus the best-ask for NO falls below $1.00, creating a guaranteed spread when you buy both sides. In that scenario, you lock in a risk-defined profit equal to the difference between $1.00 and the total cost of both legs, minus the per-contract fee. Understanding this intra-market dynamic is essential for identifying consistent, repeatable opportunities within Kalshi markets.
Combinatorial and endgame arbitrage tactics
Some events group multiple child markets under a single event ticker. If the sum of the child YES prices is less than $1.00, you can purchase a complete set of child YES contracts and lock in the spread across the bracket. In the final hours before settlement, some traders pursue endgame yields by targeting YES contracts priced high but below $1.00, seeking small but relatively predictable returns. These strategies rely on precise pricing, liquidity, and timely execution, as well as awareness of settlement rules and potential slippage or partial fills.
