A long position is a holding you have bought and still own, where you stand to gain if its value rises and to lose if it falls.

To be long something is to own it after buying it, in the hope or expectation that it becomes more valuable. In an event contract, going long a yes contract means you bought yes and now hold it. You gain if the price of yes rises, or if the event resolves in the way your contract pays. You can be long the no side just as easily, since if you buy and hold no contracts you are long no, and you gain if no becomes more likely or settles in your favour.
The opposite of a long position is a short position, where you have sold something you expect to fall. On many prediction markets the structure means that being long no is the everyday way to express a bearish view on yes, rather than formally shorting. The key idea of long is simply this: you own it, you paid for it, and your outcome moves with its price. If it rises you are ahead, if it falls you are behind, and at settlement the contract pays its fixed value or nothing.
Your risk on a long event contract is usually limited to what you paid for it. If you buy a contract at forty cents and it settles worthless, you lose those forty cents per contract and no more, because the price cannot fall below zero. Your gain is capped too, since most event contracts settle at a fixed ceiling such as one dollar. That bounded shape is one way event contracts differ from instruments where a long position can lose more than the stake or gain without limit.
Holding a long position is not free of decisions after you buy. The price will move while you hold, sometimes sharply, and you can choose to sell before settlement to lock in a gain or cut a loss, or to hold until the event resolves. How large a position to take, and how much of your funds to commit to any single one, is a question of position sizing and risk rather than of the term itself. Being long only describes the direction of the bet, not whether it is a wise size.
You buy ten yes contracts at forty cents each, paying four dollars in total. You are now long ten yes contracts. If the price rises to sixty cents you could sell for six dollars, a two dollar gain before fees. If the event resolves no, your contracts settle at zero and you lose the four dollars you paid, which is the most you could lose on that position.
Illustrative only. Numbers are examples, not a quote or a prediction, and exclude fees.
A long contract can fall to zero and leave you with nothing, so the amount you commit to any single position is the amount you can lose on it. 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 means you bought something and still hold it, expecting to gain if its value rises. In event markets you can be long yes or long no depending on which side you hold.
Usually only what you paid, since the price cannot fall below zero. If you bought at forty cents and it settles worthless, you lose forty cents per contract and no more.
Not exactly. Being long describes holding a contract you bought, which can be the yes side or the no side. Long no is a common way to take a bearish view on yes.
No. While the market is open you can usually sell a long position before the event resolves, to take a gain or limit a loss, subject to there being a buyer at a price you accept.
