A lot of prediction market participants do not run the preparation, research and learning loops that are standard in mature markets. The point of paper trading is to give you the tools to test strategies and get familiar in a safe environment.

  1. Step one

    Find markets you want to follow.

    The scanner lists every market on Polymarket and Kalshi carrying at least $5,000 in volume, plus anything you follow and anything a Chironus article is tracking.

    Following an event puts every market inside it on your Dashboard.

    Free users can follow up to 10 events at a time. Pro users are unlimited.

  2. Step two

    Set and manage alerts.

    • Daily morning brief: a 24 hour snapshot of movements on your followed events.
    • Alerts as prices move: Pro accounts get an email within a minute or two.

    Sensitivity starts at a 10 percent move and can be adjusted globally or per event.

  3. Step three

    Execute a mock trade.

    Paper trading uses simulated funds, not real money.

    Every account starts with $1,000 in simulated funds, and the balance can be set to anything up to $1,000,000.

    Free users can hold 5 open positions at a time and place up to 5 trades a day. Pro users are unlimited.
