What the report shows
- Realized P&L after fees, across every closed or resolved position, including winners not yet redeemed.
- Fees paid. Most Polymarket markets are fee-free, but some charge the taker, and on active accounts it adds up.
- P&L by category and holding time, to see whether the edge is in sports, politics or crypto, and whether quick flips or held positions pay.
- Best and worst markets, the trades that made or broke the record.
FAQ
- How do I see my total profit on Polymarket?
- Paste your wallet address above. The tool reads every trade the wallet made from Polymarket's public data, settles positions in markets that have resolved, and adds up realized profit after fees, along with win rate and where you win and lose.
- Where do I find my Polymarket wallet address?
- Open your profile on polymarket.com and copy the address that starts with 0x. A profile link that contains the address works too.
- How is Polymarket P&L calculated here?
- Each position is one market and one outcome. Buys set a weighted-average cost that includes any fee; sells and resolution realize the difference against it. A resolved market pays $1 per winning share whether or not it has been redeemed yet. Fees come from the cash each trade actually moved, so markets that charge a taker fee are counted correctly.
- Why is my number different from my Polymarket profile?
- Polymarket's profile also counts open positions at today's price and adds maker and taker rebates. This tool reports realized P&L: closed and resolved positions only, so a position still open counts once it is sold or resolves. Splits, merges and conversions are not included.
- Can I look up someone else's wallet?
- Yes. Every Polymarket wallet's trades are public on-chain, so any address works, including the traders you follow.
- Can it update automatically?
- This free tool reads up to 5,000 recent trades per lookup. FillBook syncs your wallet every day with the full history, adds a journal note to every trade, and shows Kalshi and Polymarket side by side.
