About

DemoMarket is a Chrome extension that lets you practice trading on Polymarket without risking real money. It adds a "Demo" button directly to Polymarket's trading interface, allowing you to simulate buy and sell orders using virtual funds. Every trade you make is tracked with real-time market prices, giving you an authentic trading experience while learning how prediction markets work.

Whether you're new to prediction markets or want to test trading strategies before committing real capital, DemoMarket provides a risk-free environment to experiment. The built-in dashboard displays your portfolio holdings, profit/loss calculations, and complete transaction history. Your virtual portfolio persists across browser sessions, so you can track your performance over time and see how your predictions would have played out in the real market.
