A stake is the amount of money you commit to a position, the sum you put at risk on a contract and the most you can lose if it resolves against you, before fees.

Your stake is simply the money you commit when you take a position. If you buy a yes contract at forty cents and buy ten of them, your stake is four dollars. That four dollars is what you have placed at risk. On a standard yes or no event contract a long position settles at one dollar each if the outcome happens and at zero if it does not, so the stake you paid is normally the most you can lose on that position. The word carries over from everyday language about putting something on the line, and it means the same thing here: the capital you have committed and could forfeit.
It helps to separate the stake from two related ideas. The stake is what you pay to enter. The potential payout is what the position returns if it resolves in your favour, which on these contracts is the number of contracts times one dollar. The profit or loss is the difference between the two once the position closes. A common mistake is to think of the headline payout as the figure that matters, when the stake is the figure that defines your exposure. You can always lose your full stake.
Stake size is also where risk management lives. The probability of an outcome does not change with how much you commit, and neither does the price, so a larger stake does not improve your odds. It only scales the result. Doubling your stake doubles both the amount you can win and the amount you can lose. Because of that, many careful participants think first about how much they could comfortably lose on a position and let that set the stake, rather than starting from how much they hope to win. How much to stake is a personal decision that depends on your own circumstances, and it is not something this page advises on.
One caution on language. Most simple event contracts make the maximum loss equal to the stake, but not every structure behaves that way. Some positions, such as selling or shorting certain contracts, can expose you to a loss defined differently from the cash you put up, and platforms vary in how they describe and collateralise risk. Always read how a specific contract and venue define your maximum loss before you commit, rather than assuming the stake is the whole story.
You buy twenty yes contracts at thirty cents each, so your stake is six dollars. If the event resolves yes, each contract pays one dollar and you receive twenty dollars, a profit of fourteen dollars before fees. If it resolves no, the contracts settle at zero and you lose your full six dollar stake. The size of the stake set both outcomes in advance.
Illustrative only. Numbers are examples, not a quote or a prediction, and exclude fees.
Your stake is money you can lose in full. Stake only what you can afford to lose, never to chase a loss, and never on borrowed money. A larger stake does not improve your odds, it only raises what is at risk. If it stops feeling like a free choice, step back.

A stake is the amount of money you commit to a position. It is the sum you put at risk on a contract and the most you can lose if the contract resolves against you, before any fees.
On most yes or no event contracts your maximum loss on a long position is the stake you paid, because a contract that resolves the wrong way settles at zero. Other structures can behave differently, so always check how a given contract and platform define risk.
That is a personal decision and not something we advise on. Many careful participants size each stake as a small fraction of money they can afford to lose, and never stake money they need. The right number depends on your own situation.
No. The size of your stake does not change the probability of the outcome or the price. A bigger stake only scales the amount you can win or lose, so it raises both your potential gain and your potential loss.
