How this service works
Get profit and loss breakdown for all traders in a specific prediction market. Includes buy cost, sell proceeds, redemption values, and unrealized positions. **What it helps to answer:** 1. **Who are the biggest winners and losers in this market?** 2. **What is the PnL distribution across traders?** 3. **How much unrealized value exists in open positions?**
Output
A paginated list of trader-level PnL records for the specified market, each containing the trader wallet address, SAFE proxy owner address, total PnL in USD, net buy cost, net sell proceeds, redemption value, unrealized value, the side held (Yes/No/Both), the market question, event title, and whether the market is resolved.
Example use cases
Example prompt
“Show me the top 20 traders by total PnL in Polymarket market ID 654412, sorted from highest to lowest profit, so I can see who the biggest winners and losers are.”
Technical details
Endpoint
POSThttps://api.nansen.ai/api/v1/prediction-market/pnl-by-market?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a full per-trader PnL breakdown for a specific Polymarket market — particularly when identifying top winners/losers, analyzing unrealized exposure, or building a trader leaderboard. Prefer this over general wallet PnL endpoints when the scope is a single prediction market and you need cross-trader comparison rather than a single wallet's history.
