Chrome Extension

Trade Polymarket without leaving the page

Download the extension, load it in developer mode, and start trading. Takes about a minute.

Chrome, Brave, Edge, Arc - any Chromium browser

Ballista is not on the Chrome Web Store yet, so it installs as an unpacked extension. The steps below cover it.

Install in 5 steps

1
Unzip the download
Extract the archive to a folder you will keep around - Chrome loads the extension from that folder, so deleting it uninstalls the extension.
2
Open the extensions page
Paste this into your address bar (Chrome blocks links to it):
3
Turn on Developer mode
Flip the Developer mode toggle in the top-right corner of that page.
4
Click Load unpacked
Select the folder you extracted in step 1. Ballista appears in your extension list right away.
5
Pin it and open Polymarket
Pin Ballista to your toolbar, sign in with your Ballista account, and the trading panel shows up on every market page.

Buy and sell straight from any Polymarket market page - no tab switching, no copy-pasting.

Orders fire the moment you click. No confirmation mazes between you and the fill.

Save named order configurations and fire them in one click on any market.

Same wallet and balance as the Telegram bot, Discord bot, and web platform.
