How to get alerts when Kalshi changes market rules

Put the market on a RulesWatch watchlist and add an alert channel: a Discord webhook, a JSON webhook, or the private RSS feed every watchlist has. Watched markets are checked every 5 minutes, and the alert carries the changed words, the edit window and the Yes price. The free plan covers 1 market and one Discord channel; Pro is $12, paid once. Since I started recording on Oct 31, 2026, I recorded 0 edits to Kalshi markets.

Steps

  1. Open the watchlist and paste a Kalshi market link (kalshi.com/markets/…) or a ticker such as KXHOUSE-26. Polymarket links work too. Or press Watch on any market page.
  2. On alerts, add a channel. Each one gets a test message right away.
  3. That's all. There's no account: the watchlist lives under a random code in your browser. Copy its private link or add a passkey to open it elsewhere.

Alert channels

  • Discord: a channel webhook URL. Free includes one.
  • Telegram (Pro): off on this site.
  • Webhook (Pro): any HTTPS address that takes a JSON POST, such as n8n, Zapier, Make or your own server. The payload has the before and after text of each field. Format: alerts docs.
  • RSS: every watchlist has a private feed. The public feed of all edits is /feed.xml.

How fast

An alert goes out on the run that finds the edit or the next one; runs are every 5 minutes. The edit itself happened somewhere in the edit window before detection, since Kalshi doesn't publish edit times.

What I compare on Kalshi

The title, the outcome name, the primary and secondary rules, the close time, the expiration time and the early-close condition. A close time moved to the moment a market closes early is not counted, since the rules allow it.

Every edit: changes feed. Setup details: alerts docs.
