Returns every wallet with a position in a single market, broken out by outcome (e.g. Up/Down or Yes/No) and ranked by P&L. The natural feed for “top traders on this market” leaderboards, top-X-by-PnL widgets, and per-market trader audits.

Path accepts either the market slug (e.g. btc-updown-5m-1777179000) or the condition_id (e.g. 0xa7ae8a41...). It does not accept an outcome token id — pass the market identifier, not the side.

Field shape is camelCase (avgPrice, realizedPnl, etc.) — distinct from polynode’s V2 onchain endpoints which use snake_case. Different schemas, different use cases. Default cap is 50 rows per outcome; configurable up to 500.

Request

GET /v1/markets/{slug-or-condition-id}/positions

Parameter	Type	Location	Description
id	string	path	Market slug or condition_id (0x…). Not an outcome token id.
limit	integer	query	Max rows per outcome. Default 50, max 500.
offset	integer	query	Skip first N rows.
sortBy	string	query	TOTAL_PNL (default), REALIZED_PNL, CURRENT_VALUE, SIZE, INITIAL_VALUE.
sortDirection	string	query	DESC (default) or ASC.
status	string	query	OPEN, CLOSED, or ALL (default).
min_size	number	query	Drop positions with size < min_size from each outcome. Use min_size=0.0001 to filter to current holders only (excludes historical participants who closed out to zero).
includeTrades	boolean	query	When true, adds firstTradeAt / lastTradeAt (unix seconds) per row. Heavy — separate 20 req/min rate limit per key.
user	string	query	Filter to a single wallet, or up to 20 wallets comma-separated, scoped to this market.

TOTAL_PNL and REALIZED_PNL are sorted by Polymarket’s data-api directly. CURRENT_VALUE, SIZE, and INITIAL_VALUE are sorted in-process after the fetch (and after min_size if set), so they pair cleanly with the holder-filtering use case.

Notes

• Default cap of 50 rows per outcome unless limit is set higher (max 500). On very large markets with deep tail traders, paginate with offset.
• Sort ties on equal P&L are non-deterministic — two wallets at the same totalPnl may swap positions between calls. Use proxyWallet as a stable secondary key on the client side if you need consistent ordering.
• size = 0 is normal on closed positions, redeemed positions, or fully-exited positions. Use realizedPnl and totalBought to detect history.
• firstTradeAt / lastTradeAt require ?includeTrades=true and trip a separate heavy-endpoint rate limit (20 req/min per key). Don’t request it on every refresh — fetch once and cache.
