How to Bet on Polymarket and Kalshi: Read the Access Rules First

The model behind how to bet on Polymarket and Kalshi

A prediction market prices an election or a rate decision the way a sportsbook prices a football match: as a number between zero and one, moving as new information lands. That resemblance is also where most guides stop, and where this page starts, because the real question for a reader outside the United States is not how to place the trade. It is who actually lets you in. This sits alongside the wider guide to reaching Pinnacle and its brokers, and it borrows the same habit from that guide: read the rule before you read the pitch.

Three separate sets of rules stack on top of each other, and each one can block you on its own. The first is the operator's own list, and Polymarket actually publishes two of them that do not agree. Its API documentation marks a run of countries as closed to new positions only, while its help center marks some of those same countries, Ireland, Japan and the Netherlands among them, as blocked outright. Kalshi does not publish a country list at all on the pages we could read; it points to a section of its own Member Agreement that returned a server error on every attempt (the page that matters most is often the one that will not load). The second layer sits with the reader's own country, independent of anything either operator says about itself. According to a summary of Wikipedia's article on Polymarket, authorities in several countries, including France, Belgium and Poland, have taken action against it as an unlicensed gambling operator, a fact neither of Polymarket's own restriction pages mentions. The third layer is the broker's own terms, and it applies even where the first two would let you through: BetInAsia, MadMarket and Sportmarket each separately exclude the United States, the United Kingdom and France from opening a broker account at all, in the copies of their terms we could read (not the operator's exclusion, a second one, stacked on top of it).

Three layers apply at once, and each one is its own way to be told no.

We would treat the gap between Polymarket's two official pages as reason enough to check the live page yourself rather than trust either summary, because a document that contradicts its own sibling page is not a reliable source on its own. A broker account does not change what Polymarket or Kalshi decide about your own country. Nothing below should be read as though it did.

A prediction market is not the same thing as a betting exchange, even though both let two sides trade a price instead of accepting a bookmaker's number. An exchange settles a sports result; Polymarket and Kalshi settle almost anything with a public outcome, and the rulebook that decides when a market resolves lives with the operator, not the broker. For the fuller read on why Polymarket's own two lists disagree, and what that means market by market, the longer breakdown of Polymarket's access rules goes further than the summary above.

What no broker will tell you

Every broker page we read describes what its own tool offers. How a BLACK, Edge or Pro account actually relates to Polymarket's or Kalshi's own rules about where you are trading from is something no broker describes. That gap is the actual answer to "does a broker get me past the country list", and the honest answer is that nobody involved has published one.

That last point is not a small print line: none of the four brokers this site tracks was built for a reader who only wants Pinnacle's own price on a football match. For that comparison across all four, on the ground where they actually compete, the wider broker comparison covers ground this page does not (fees, KYC and complaint records that have nothing to do with prediction markets).

If you are betting from the United States

Kalshi is regulated by the CFTC and runs its own app for US customers; Polymarket blocks trading on polymarket.com for anyone in the United States and points them to a separate site, polymarket.us. Neither gap is a broker's problem to solve. MadMarket's own terms exclude the United States outright, so does BetInAsia's, and so does Sportmarket's, in the copies we could read, which makes a US reader's route back to either market the operator's own app, not a workaround through any of the four brokers above.

Fees are the other question this page will not answer in full. Polymarket publishes a fee formula and a stated rate for sports markets; Kalshi's own fee schedule was not readable at the time this was checked. The full comparison, including the arithmetic against a sportsbook's margin, lives on the page that compares prediction markets with a sportsbook price, not here.
