Kalshi Spot Caller

Follow one permanently chosen chat user free, or unlock unlimited filters for $5 once. Account required.

Follow the callers you choose in Kalshi live chat. Kalshi Spot Caller filters the chat view by exact username, helping you keep up with selected people as messages arrive. Toggle filtering off to see everyone again. • Sign in with Google to keep your filter list and purchases linked to your account. • Free plan: follow one permanently chosen username. You explicitly confirm it before saving; it cannot be changed on the free plan. • Unlimited plan: pay $5 USD once to add and change an unlimited list of usernames. No subscription. • Optional donations support development and do not unlock filters. • Saved filters sync through your account. Chat text is processed locally in your tab. Open a Kalshi market with live chat, open the extension, sign in, and select a username. Refresh an existing Kalshi tab after installing. Google sign-in is required. The $5 upgrade uses Stripe-hosted checkout. This extension works with messages available in the page; it is not a complete chat archive and does not retrieve all historical messages. Kalshi website changes may affect compatibility. Independent product, not affiliated with or endorsed by Kalshi. Does not place trades or provide investment advice.
