What you get
The numbers Polymarket
leaves out.
Realized PnL on every trade
Polymarket hides realized profit and loss. Datadash surfaces it per trade - plus current value, open PnL and ROI on every position, with a price chart a click away.
Copytrade signals
Each trader's highest-conviction positions, scored 0–100 with entry slippage, relative size and days to resolution - so you can spot the smart money and copy their edge.
Top holders, ranked by profit
Turns an event's per-market holder lists into one aggregated table sorted by total PnL - names and avatars resolved - so you see who's actually up.
Trader cohorts
Group wallets by your own criteria, tag any profile into a cohort inline, then filter every table by cohort to track just the traders you follow.
Filter anything
Filter every table by market, price, amount, PnL, ROI, rank, date, action or cohort. Stack multiple filters at once to surface exactly the rows you care about.
Follow & market activity
Follow any wallet from its profile and read a market-wide trade feed for every event - realized PnL and the trader behind each fill - all without leaving the page.

Questions
Is it free?
Yes. The extension is free and only runs on polymarket.com. Signing in (via Privy) is optional - it unlocks Follow and cohorts.
Does it need my wallet or private keys?
No. It reads public Polymarket market data and Datadash analytics. It never asks for a private key or signs transactions.
Where does the data come from?
Public market data comes from Polymarket's own APIs; the analytics (realized PnL, signals, holders) come from the Datadash backend.
Is this affiliated with Polymarket?
No. Datadash is an independent analytics layer and is not affiliated with or endorsed by Polymarket.
