Methodology

How Foreseez reads public markets from Polymarket and Kalshi, and what the numbers on a page mean.

Where the data comes from

Foreseez reads public events and prices from Polymarket and Kalshi.

We only show prices; you can't place trades here. Foreseez is independent. We aren't affiliated with, endorsed by, or sponsored by Polymarket or Kalshi. Their names and logos belong to their owners and are used only to identify where the data comes from.

How fresh it is

List prices refresh about once a minute. An event page also asks the venue for the current price when you open it, and the chart is read live. The stored quote is what you see first, until that request returns.

What's included

The live list shows open events. We leave out:

  • Sports and esports
  • Kalshi combo markets

Weather and short-lived markets stay. A market that has never traded stays in the catalog and sorts below markets that have traded. Traded only hides the never-traded rows.

What the percentage means

The percentage is the market's price for Yes. It is the midpoint of the best bid and ask when both exist and the spread is at most 10¢. Otherwise it is the last trade. With neither a usable book nor a last trade, the page shows no price.

What's not here yet

Markets are not matched across venues yet.

Not advice

Nothing on Foreseez is financial advice. Read the Terms.
