How to Find and Export Your Polymarket Trading History

What your history can show

Polymarket’s documented activity model can include trades, deposits, withdrawals, redemptions, rewards and other account events. A trade row can include the market, outcome, Buy or Sell side, share amount, dollar amount, price, time and a transaction hash. That makes an activity timeline useful for reconstructing what happened, but only if you preserve the event type beside the numbers.

A current portfolio is a different view. It describes what is held now and may include current value or unrealized performance. A closed position is different again: it summarizes a position that was exited or resolved. Use the activity timeline for an event-by-event record, and use positions to understand current or closed exposure.

Trades, positions and transfers compared

For example, imagine a $12 sale appears in activity, while the portfolio still shows an 8-share position in the same outcome. That can be consistent with a partial exit rather than a missing record. Check the sell row’s shares and time, then compare them with the remaining position and any current open order before adding the sale to a spreadsheet.

Export without assuming a button

First, look in the current official account view for a clearly labelled Download or Export action. If it exists, select the narrowest useful date range and review whether the resulting file identifies the event type and time as well as the market and amount. Save the original file unchanged, then make a working copy if you need to classify or calculate anything.

If no official export action appears, do not invent one from an old tutorial. The current primary sources reviewed here document two different data routes: public wallet activity data and authenticated account-trade records for developers. They do not establish a consumer CSV button or a standard personal-tax report. A manual spreadsheet can be more reliable for a limited period if each row is copied from the original account record and labelled with its type.

For a larger technical export, treat a wallet address and its activity as sensitive financial information even when the data route is read-only. Use only official documentation, avoid sharing keys or secrets, and validate a small date range before relying on a file. This is record-keeping guidance, not tax, legal or financial advice.

Reconcile a record before using it

Use the same fields each time: date and time, event type, market, outcome, Buy or Sell side where applicable, shares, price, dollar amount and transaction reference. A simple reconciliation asks whether the shares in a matched trade explain the position change that follows. It does not assume that the activity’s dollar amount equals a current position value.

Then check the boundary between trading and settlement. A redemption after a market resolves is not a sale before resolution; a withdrawal is not a redemption; and an open order is not a completed trade. Those distinctions prevent the common error of counting the same economic event twice in a personal record.

Common history mistakes

• Calling a portfolio snapshot a trade ledger: use dated activity rows to establish what happened.
• Mixing trades and transfers: group purchases and sales separately from deposits, withdrawals and redemptions.
• Counting an open order as a completed sale: reconcile matched shares and the remaining live order separately.
• Using a current price to rewrite an old trade: preserve the record’s execution fields and time, then compare valuation separately.
• Trusting a third-party “exporter” with secrets: never enter account credentials, recovery phrases, private keys or API credentials outside the official flow.
