Questions
What do the odds on this site mean?
Each figure is the price traders pay for a Yes share on that venue, read from the venue's public market data. A Yes share pays out one dollar if the event happens, so a price of 34 cents is read as a 34% chance. It is the market's price at that moment, not a forecast by this site.
Why do Polymarket and Kalshi show different prices for the same question?
They are separate markets with different traders, fees, deposit methods and resolution rules, and the wording of two similar questions often differs in a detail that matters. A gap can also close or widen within minutes. Compare the rules of both markets before treating them as the same bet.
How is a Polymarket outcome resolved, and what is a dispute?
Polymarket uses the UMA optimistic oracle: someone proposes the outcome, and if nobody challenges it during the challenge period it stands. A challenged proposal is a dispute; UMA token holders then vote on the outcome. The disputes page lists the outcomes we saw challenged.
Can I use Polymarket or Kalshi in my country?
It depends on the venue and on your country, and both change. The country page shows each venue as open, close-only or blocked where we have checked it, with the source page and the date. Always read the venue's current terms and your local rules before you trade.
Why is the volume in dollars for one venue and in contracts for the other?
Each venue reports volume in its own unit: Polymarket in US dollars, Kalshi in contracts. The site shows each in its own unit and never adds them together.
Is this betting or investment advice?
No. The site shows prices and records; it does not take bets, hold money or tell you what to trade.
