What is a position on Polymarket?
The shares a trader holds in one outcome of a market.
Definition
A position is the shares someone holds in one outcome of a market, such as 5,000 Yes shares bought at an average of 42¢.
In more detail
A position stays open until it is sold or the market resolves. Traders often add to or trim a position over time, so the average price changes.
On Polymarket, positions are public. Anyone can see what a wallet holds and what it paid.
