Price Alerts — Browser Notifications for Market Moves

Monitor any Polymarket probability level and get a browser notification the moment a market crosses your threshold, even when Kuroko is in a background tab.

Price alerts let you track market probability levels without watching the screen. Set a threshold on any market — above or below a given percentage — and Kuroko sends you a browser notification the moment that level is crossed. Alerts fire once and then mark themselves as triggered, so you won’t receive duplicate notifications for the same event.

Kuroko needs browser notification permission to deliver alerts. The first time you enable notifications or create your first alert, your browser will prompt you to allow notifications from Kuroko. Grant permission to receive alerts when the terminal is in a background tab.

How alerts work

Kuroko evaluates all active alerts on a 60-second polling cycle. On each tick, it compares every alert’s threshold to the current market probability:

• Above — fires when the probability is greater than or equal to your threshold
• Below — fires when the probability is less than or equal to your threshold

When an alert fires, Kuroko sends a browser notification showing the market question and the current probability. The alert is then marked as triggered and deactivated — it won’t fire again for the same threshold crossing.

Triggered alerts remain visible in the Recently Triggered section at the bottom of the Alerts panel so you have a record of what fired and when.

Creating an alert from /markets

1. Browse to the Markets page

   Go to /markets. Use the search bar, category filter, or probability range filter to find the market you want to monitor.

2. Open the alert form

   On the market card, click Set Alert. This opens the alert creation form without navigating away from the page.

3. Choose a direction

   Select Above if you want to be notified when the probability rises past your level, or Below if you want to be notified when it falls.

4. Enter your threshold

   Type a probability percentage between 1 and 99. For example, enter 70 to be notified when the market crosses 70%.

5. Save the alert

   Click Save Alert. The alert is active immediately and will be evaluated on the next 60-second poll.

Creating an alert from /portfolio

You can also manage all your alerts from the Portfolio page. On desktop, the Alerts panel is in the right column. On mobile, tap the Alerts tab.

Click + Add Alert, then follow the same steps: search for a market, select a direction, enter a threshold, and save.

Alert conditions

Above

Fires when the market probability reaches or exceeds your threshold. Use this to catch upward momentum — for example, alert when “Fed cuts rates in June” hits 70%.

Below

Fires when the market probability drops to or below your threshold. Use this to catch declining conviction — for example, alert when a position you hold falls under 40%.

Notification toggle

The Alerts panel has an On / Off toggle that controls whether browser notifications are fired when alerts trigger. This is separate from browser permission — if you’ve granted permission but toggle notifications off, alerts will still be evaluated and marked as triggered, but no notification will appear.

To re-enable notifications, click the toggle back to On. If browser permission has been revoked, Kuroko will prompt you to grant it again.

Setting alerts via AI chat

You can create alerts directly from the AI chat at / using the /alert command or plain language. For example:

/alert when Fed rate cut goes above 70%

Or conversationally:

Alert me if Trump wins 2026 midterms drops below 35%

This is the fastest way to set an alert while you’re already researching a market in the chat.

Storage

Alerts are stored in your browser’s localStorage under the key kuroko_alerts. They persist across page reloads and sessions but are specific to the device and browser you’re using. Clearing your browser storage will remove all alerts.
