Payout
The USDC amount received per outcome token at settlement — $1.00 for a winning token, $0.00 for a losing token.
Definition
Payout is the cash value received when an outcome token is redeemed after market resolution. Winning tokens pay $1.00 USDC per token; losing tokens pay $0.00. A position of 100 YES tokens that resolves as a win pays out 100 USDC regardless of the price at which the tokens were purchased. The profit is the payout minus the purchase price (and fees).
In practice
A bot that buys 50 YES tokens at $0.52 each spends $26. If YES resolves as the winner, the payout is $50 (50 tokens × $1.00), for a gross profit of $24. Subtracting the entry taker fee (roughly $0.40 at $0.52 on a crypto binary), the net profit is about $23.60. Predtools bots calculate expected payout at entry time to verify that the signal edge exceeds total fees. The bot does not need to place a sell order to collect payout — Polymarket credits the USDC automatically after resolution.
