Outcomer vs Kalshi: does Kalshi's 'global' expansion really reach Europe?

Kalshi spent its first few years as a US-only story: a CFTC-regulated exchange built for American traders. That changed in late 2025, when the company raised over $300 million at a $5 billion valuation and announced it would open access to more than 140 countries, calling itself the "world's only unified global prediction market." For a European reader, the natural question is simple: does that actually mean you can use it now? Here is a clear comparison with Outcomer, and what Kalshi's expansion does and doesn't cover. (New to the concept? Start with what a prediction market is.)

Two different starting points

Kalshi is a US financial exchange that widened its doors. Its core identity — dollar funding, a CFTC compliance framework, an interface built to feel like a brokerage account — hasn't changed just because the country list got longer. The global rollout is an extension of a US-built product, not a product designed around European rules, payment habits or examples.

Outcomer starts from the opposite direction. It is built Europe-first: European users, European examples, and a virtual-money mode so beginners can learn how these markets work before any real money is involved. Where Kalshi added Europe on top of a US foundation, Outcomer was built for it from the start.

What "140 countries" actually includes

This is where it gets more interesting than the headline number suggests. Kalshi's own country list still restricts a long run of European jurisdictions, including Poland, France, Belgium, Bulgaria, Hungary, Ireland, Italy, Portugal, Switzerland, the United Kingdom, and several others. So "global" in practice means something closer to "most of the world except large parts of Europe" — the opposite of what the announcement implies at first glance.

There's a regulatory reason for that gap. On 17 June 2026, nine European regulators — including Germany, Poland, France, Italy, the Netherlands, Spain and Switzerland — signed a joint declaration to act together against prediction-market platforms operating without a local licence, timed to the opening of the World Cup. We covered this in more depth in Europe's regulators warn on prediction markets. Kalshi's expansion is happening into that headwind, not around it — which is a big part of why so many European countries remain restricted even as the platform grows almost everywhere else.

It's also worth remembering that Kalshi's regulatory footing at home is still being tested: in August 2026, the CFTC issued an emergency order letting Kalshi keep operating under existing rules after New York's Attorney General sued over sports-related contracts. None of that makes Kalshi illegitimate — it's a genuine, regulated exchange — but it does mean the ground is still moving, in the US and in Europe alike. For the general legal picture where you live, see are prediction markets legal in Europe.

Funding, fees and how prices work

On both platforms, the price is the crowd's probability: a contract at 63¢ means the market puts the event at roughly 63%. Kalshi is dollar-first — you fund by ACH, wire or card (card deposits carry a processing fee) — and its trading fee scales with how close a price sits to 50¢, topping out around 1.75¢ per contract at that midpoint, with maker orders charged roughly a quarter of the taker rate. That structure rewards patient limit orders over rushed market orders.

Outcomer keeps the same core mechanic — Yes/No shares, a live price that reads as a probability — without asking a European user to first navigate a US-oriented funding flow. If you want the fuller two-way comparison against the other major US platform, we also wrote Polymarket vs Kalshi.

Learning curve and risk

Kalshi's interface is deliberately built to resemble a brokerage account, which lowers the learning curve if you already trade options or futures. But that familiarity doesn't remove the two things that matter for a beginner anywhere: market risk (you can be right about the world and still lose money on timing or price) and platform risk (does this service even work reliably from where you live).

That second question is exactly why we think beginners — wherever they are — benefit from starting in a virtual-money environment. Reading a price as a probability, sizing a position, deciding when not to trade: these are skills, and they transfer regardless of which platform you eventually use for real. We go deeper on this in trading with virtual money.

So which should you choose?

If you're a US-based trader, or you live in one of the roughly 140 countries where Kalshi has genuinely opened access, it's a serious, regulated exchange with an interface that will feel familiar. If you're in Poland, France, Germany or several other European countries, the honest answer today is that Kalshi's "global" claim doesn't yet reach you — and even where it does, European regulators are actively pushing back on unlicensed access.

That's the specific gap Outcomer is built to fill: a platform designed around European users from day one, with no dependency on whether a US exchange's expansion map happens to include your country this quarter. None of this is financial advice — prediction markets can lose money, and the point here is understanding, not a tip.
