How KALSHI Works: a Trader’S Quick Guide
how kalshi works in practice is straightforward: you buy YES or NO contracts that settle to $1 if the outcome occurs. Kalshi is a U.S.-based, CFTC-regulated DCM where event contracts trade on a central order book. Each contract is binary, priced in cents, and settles to a fixed dollar amount, with the YES and NO sides together always totaling $1.00 at fair value. This guide explains the core mechanics and how traders look for edge, including our YES + NO < $1.00 alerts to spot guaranteed spreads.
Understanding YES and NO contracts on Kalshi
Every market on Kalshi is a binary YES/NO contract. You can buy either side, and the contract pays $1.00 if the chosen outcome occurs and $0.00 otherwise. The two sides are designed so their prices sum to $1.00 in fair value. Prices are quoted in cents, typically ranging from $0.01 to $0.99, with the 1-cent granularity allowing precise risk budgeting. The underlying event is governed by Kalshi’s resolution rule and official sources rather than external oracles, and settlements occur in USD after the event resolves.
How settlements and pricing work
Pricing on Kalshi reflects the market’s probability assessment. A YES contract priced at 42 cents implies a $0.42 cost to win $1.00 if the event resolves true; the NO side would be priced to complement so that YES_ask + NO_ask equals $1.00. The platform uses a central clearinghouse, Kalshi Klear, to settle trades and enforce self-trade prevention. Fees apply to each fill, and there are no maker rebates; the cost structure is transparent and public in the rulebook. At settlement, winners receive $1.00 per winning contract, losers receive $0.00.
Arbitrage strategies you can use on Kalshi
One common edge is the intra-market binary spread: if bestAsk(YES) plus bestAsk(NO) is less than $1.00, buying both YES and NO can lock in a risk-defined profit minus fees. In cases with mutually exclusive child markets under the same event ticker, a complete set of child YES contracts can also create a guaranteed spread when their combined asks total less than $1.00. The strategy hinges on small, repeatable differences, fast execution, and monitoring for near-term settlement dynamics.
