KALSHI Mechanics

No Contract

The NO contract is the opposite side of a binary Kalshi market, paying $1 if the event does not occur.

Detailed explanation

A NO contract is the counterparty to the YES contract in a Kalshi binary market. If the event does not happen, the NO contract settles at $1.00; if the event occurs, it settles at $0.00. Prices are quoted in cents (0.01–0.99), and the sum of the YES and NO prices should equal $1.00 at fair value. Traders can buy NO to hedge YES exposure or to exploit spreads with the YES side when edges exist. As with YES, Kalshi enforces a resolution rule and uses it to determine settlement, not an external oracle.

Worked example

If YES is priced at 42¢ and NO at 56¢, the combined price is 98¢, leaving a 2¢ edge opportunity if the two legs can be hedged together.

FAQ

What happens if I hold both YES and NO on the same event?
Holding both sides is a form of spread strategy. When YES_ask + NO_ask < $1.00, you can buy both legs to lock in a near-risk-free edge, minus the per-contract fee.
How does the NO contract settle compared to YES?
The NO contract settles for $1.00 if the event does not occur and $0.00 if it does occur, the opposite of the YES contract.
Are NO contracts subject to the same fees as YES contracts?
Yes. Kalshi charges a per-contract fee on trades for both YES and NO sides; the fee structure is the same for either side.
