A no contract is the side of a binary event contract that pays out if the defined event does not happen, settling at one dollar if it does not occur and zero if it does.

Most prediction market contracts are binary, meaning they resolve one of two ways. A yes contract pays out if the defined event happens, and a no contract pays out if it does not. The no contract is simply the other side of the same question. If you hold a no contract and the event fails to occur, it settles at one dollar. If the event happens, it settles at zero and you lose what you paid. Buying no is how you take a position on an event not happening, rather than on it happening.
Because exactly one of the two sides will pay out, the yes price and the no price on a single market are designed to add up to about one dollar before fees. If the yes contract trades at sixty cents, the no contract trades near forty cents, which reflects the roughly forty percent chance the market is pricing for the event not happening. The no price is therefore a direct reading of the implied probability of the negative outcome, in the same way the yes price reads the positive one.
Buying a no contract is closely related to selling a yes contract, since both profit if the event does not happen, and on many venues the two are economically similar. The exact mechanics differ by platform, including how each handles collateral, settlement, and fees, so it is worth checking how a given venue structures yes and no positions rather than assuming they behave identically everywhere. The headline idea is consistent, though. A no contract is a clean way to express the view that something will not occur.
A no contract is not a safe bet, despite how the word no might sound. It is a position on a specific outcome, and if the event happens it loses everything you put into it. Like any contract on these markets, the price reflects a probability and not a certainty, and the money at stake is genuinely at risk. Holding no is no more cautious than holding yes. It is simply the other half of the same uncertain question.
A market asks whether a published figure will land above a threshold by a set date. The yes contract trades at seventy cents and the no contract at thirty cents. You think the figure will fall short, so you buy no at thirty cents. If the figure does not clear the threshold, your no contract settles at one dollar. If it does clear, your no contract settles at zero and you lose the thirty cents you paid.

A no contract is a position on an outcome, not a safe bet, and it loses everything you paid if the event happens. Prediction markets can lose you money. Stake only what you can afford to lose, never to chase a loss, and never on borrowed money. If it stops feeling like a free choice, step back.

It is the side of a binary event contract that pays out if the defined event does not happen. If the event fails to occur it settles at one dollar, and if the event happens it settles at zero. It is the mirror image of the yes contract on the same market.
On a single binary market the yes and no prices are designed to add up to about one dollar before fees, because exactly one of them will pay out. If yes trades at sixty cents, no trades near forty cents, reflecting the roughly forty percent chance the market is pricing for the event not happening.
They are closely related and often economically similar, since both profit if the event does not happen. The exact mechanics depend on the platform, including how it handles collateral and fees. Always check how a given venue structures yes and no positions before assuming they are identical.
Yes. If the event happens, the no contract settles at zero and you lose what you paid. Buying no is not a safe bet, it is simply a position on the other outcome, and the money at stake is genuinely at risk like any other contract.
