Portfolio Tracker

This free portfolio tracker lets you manually manage and monitor your Polymarket prediction market positions. All data is stored locally in your browser using localStorage, so nothing is sent to any server and your positions remain completely private.

To get started, click "Add Position" and enter the market question, your side (Yes or No), the price you paid per share, and the number of shares you hold. You can optionally enter the current market price. Once added, the tracker calculates your unrealized profit and loss, the current value of each position, and your total portfolio performance.

Click on the current price cell in any row to update it with the latest market price from Polymarket. You can sort your positions by market name, P&L, or value by clicking the column headers. Each position includes a direct link to trade on Polymarket.
