Every trade you've made, in one ledger

Bring in your Kalshi history and your Polymarket wallet and get one profit & loss picture across both: what you made, what it cost you in fees, and every matched round trip — computed to the exact cent.

Import your trading history

Select as many years at once as you like. All Kalshi exports are supported: the transaction CSV, the realized P&L CSV from Account → Tax Info, and the older legacy format.

Only count tickers starting with these prefixes — for example KXMLB for MLB only, or KXMLB, KXNFL for both. Leave empty for everything.

Paste your 0x… address or profile URL. No login or signature needed — Polymarket positions are public on chain by design.

Use either one, or both together. No file handy? Load the demo data to see exactly what you get.

Getting your Kalshi CSV

  1. Log in to Kalshi on the web (not the app).
  2. Open Account → Documents.
  3. Download your transaction history CSV — one file per year if offered.
  4. Upload the file(s) here.

What you get back

  1. A P&L calendar across both venues — click any day to see the trades behind it.
  2. A shareable month card you can post, drawn in your own browser.
  3. An exact-to-the-cent FIFO ledger of every matched round trip.
  4. Your real fee drag, which no venue totals up for you.

Nothing you upload is stored. Your files are parsed in memory, the dashboard is rendered, and the data is discarded when the page is served. There is no account, no database, and nothing written to disk — close the tab and it is gone.
