About Callquake

Callquake watches the largest prediction markets, Kalshi and Polymarket, every two minutes. When the odds on something swing, we tell you how much, and we look for the news that moved them.

Why we built it

Prediction market odds now appear in news coverage and search results, but a number alone does not tell you what changed. Callquake adds the context: the history, the size of each move, and the headline behind it.

What we do and do not do

• We show odds, charts and explanations, free to read.
• We send optional alerts on Telegram, with a paid Pro plan for heavier users.
• We do not offer trading, hold anyone’s money or give financial advice.
• We are independent and not affiliated with Kalshi or Polymarket. If we ever show a link to a platform, we say when it is an affiliate link, and we only show it where trading is legal.
