PredictPedia Search finds events in the site's published Polymarket and Kalshi catalog. Search for a topic, person or event, then open a result to inspect the available markets and source links.
Compare the underlying questions
A shared topic does not guarantee identical contracts. Compare the outcome wording, deadline and resolution source before treating two prices as comparable. Displayed differences do not establish a tradable arbitrage: spreads, fees, available size and settlement differences can change the result.
Check the observation time
The catalog is a saved snapshot, with a refresh currently scheduled every three hours. It is not a streaming order book. Check the displayed observation time and open the source venue for current executable quotes. Some historical records remain accessible with older observations.
Use the supporting tools
Use the implied probability converter to compare odds formats and the Kelly calculator to explore position sizing from your own probability estimate. Neither tool supplies a forecast or places an order. The guide to reading order books explains why a displayed price can differ from the cost of an actual trade.
