Polymarket, Kalshi and the Line Between Crypto Trading and Gambling: How Europe Regulates Prediction Markets in 2026

Prediction markets have moved from a niche internet idea into a regulatory question that European authorities now treat seriously. Services such as Polymarket and Kalshi let users take positions on whether a future event will happen, with subjects ranging from elections and sport to inflation, interest rates, weather and cryptocurrency prices. The experience can look like trading because contracts can have market prices and, in some cases, can be bought and sold before an event is resolved. Yet the economic result can also look very similar to betting: money is placed on an uncertain event and the final payout depends on whether a stated outcome occurs. As of September 2026, Europe has no single legal category or licence that covers every prediction market. EU financial rules may apply to some event contracts, while national gambling laws may apply to others, and the same service can face different treatment from one country to the next. The central regulatory question is therefore not whether a site uses crypto, trading language or an exchange-style interface, but what the contract actually does, what event determines the payout and which law applies in the user’s country.

Why Prediction Markets Blur the Line Between Trading and Gambling

A typical prediction market is built around a question with a defined future outcome. A contract might ask whether an election candidate will win, whether a central bank will change interest rates, whether a team will win a match or whether Bitcoin will finish above a particular price at a stated time. Users take one side of the question, and the contract is settled according to pre-set rules and a stated source of information. This is different from buying a company share, because the user is not acquiring ownership in a business or a claim on its future profits. It is also different from an ordinary sportsbook bet in presentation, because the position may be quoted as a tradable contract whose price can move as other users buy and sell. That combination explains why regulators increasingly use the term “event contract” when discussing prediction markets. The product may resemble a financial instrument in form while producing a betting-like result in substance.

Polymarket and Kalshi show two different ways of building this model. Polymarket’s own 2026 help material explains that users trade positions on future event outcomes and that opposing YES and NO positions are fully collateralised by one US dollar in USDC; the position linked to the correct final outcome is paid one US dollar in USDC when the market is resolved. Kalshi also uses event contracts, but its home-market structure is different: it is a US Commodity Futures Trading Commission-designated contract market, and its standard prediction contracts are framed as regulated event contracts rather than crypto bets. Kalshi states that a correct contract is worth one US dollar at settlement. These structural differences matter for how each business operates, but they do not by themselves decide European legality. A US regulatory status does not automatically grant permission to serve European consumers, and the use of USDC does not automatically turn a gambling product into a regulated investment product.

The legal boundary becomes clearer when attention shifts from branding to economic substance. If a consumer pays money for a chance of receiving a fixed amount depending on an uncertain sporting, political or other non-financial event, a national gambling authority may view the arrangement as betting. If the event contract is linked to a financial variable and meets the legal definition of a financial instrument, securities and derivatives rules may apply instead. Some contracts can sit close to both categories, which is why 2026 guidance from European regulators focuses on the individual product rather than on a broad label such as “prediction market”. This approach also prevents a simple change in terminology from changing the law. Calling a stake a “trade”, showing a moving price chart or settling through a cryptoasset does not remove the underlying question: what is the customer paying for, and what event decides whether that customer receives money back?

What Makes an Event Contract Look Like a Trade — and Like a Bet

The trading characteristics are easy to see. A contract can have a quoted price, users can take opposing positions, and that price can change when new information arrives. On some services, a user can close a position before the event is finally resolved rather than waiting for settlement. This creates familiar market behaviour: traders may enter at one price, exit at another and attempt to profit from changing expectations. The price can also serve as a compact measure of collective sentiment. A YES contract trading at 0.65, for example, is often interpreted informally as the market assigning about a 65% chance to the event. That interpretation can be useful, but it should not be confused with an official forecast or a statistically guaranteed probability. The price is produced by participants, liquidity, market rules and available information, not by an independent forecasting authority.

The betting characteristics are just as important. Many event contracts end with a binary result: the event either happens or it does not, and the correct side receives a fixed payout while the losing side does not. The consumer therefore risks money on an uncertain future outcome, often on topics that have long been associated with betting, such as sport or elections. This resemblance becomes stronger when the contract has no clear investment or hedging purpose and is used mainly for short-term speculation. European authorities have also focused on the behavioural features surrounding these products, including continuous access, rapid repricing and the ability to move from one topical event to another. Those features can make the activity feel more like active trading, but they can also encourage repeated staking in a way familiar to gambling regulators.

For users, the practical distinction matters because the protections can be very different. A regulated investment firm is normally subject to financial conduct, disclosure and authorisation rules, while a licensed gambling operator is subject to rules on matters such as age verification, safer gambling, betting integrity and customer protection. An unlicensed service may sit outside both sets of protections in the country where the user lives. That is one reason a market-style interface should not be treated as evidence that a product is a conventional investment. A prediction price can be informative, but it can also move sharply when trading is thin, when a major participant enters or exits, or when the wording and resolution rules are misunderstood. Before placing money at risk, the more important questions are who regulates the operator locally, what legal category applies to the contract and what recourse exists if settlement or withdrawals are disputed.

How the EU and European Regulators Treat Prediction Markets in 2026

The European Union does not have a single prediction-market licence that overrides national rules. Instead, authorities examine the characteristics of the event contract. On 3 July 2026, the European Securities and Markets Authority addressed the growth of prediction markets directly. ESMA described event contracts as products whose financial outcome is binary and depends on a yes-or-no answer about a future event. Crucially, it stated that the nature of the underlying question determines whether a contract qualifies as a financial instrument, and it also noted that an event contract may qualify as a bet under national gambling law. This means that two contracts offered through the same site can potentially fall into different regulatory categories. A contract tied to a financial benchmark may be assessed under financial-market law, while a contract on a sporting or political result may be assessed primarily under a country’s gambling legislation.

ESMA also clarified what happens when an event contract does qualify as a financial instrument. In that case, it is treated as a derivative, and its binary payout can bring it within existing national product-intervention measures on binary options. Those measures prohibit the marketing, distribution or sale of covered binary options to retail clients. ESMA further reminded firms that distributing event contracts that qualify as financial instruments in the EU requires investment-firm authorisation even when the contracts are offered only to non-retail clients. In plain terms, presenting an event contract as a financial product does not create a regulatory shortcut. If it is genuinely a financial instrument, financial-services rules follow it; if it is a bet, national gambling rules can apply. The 2026 position therefore narrows the space for businesses that try to rely on ambiguous terminology while avoiding both licensing regimes.

National gambling regulators are acting in parallel with ESMA. On 17 June 2026, authorities from Belgium, France, Germany, Italy, the Netherlands, Poland, Portugal, Spain and Switzerland issued a joint statement on prediction markets. They agreed to increase co-operation against services that do not comply with local rules and highlighted concerns including round-the-clock access, insufficient age or identity controls, lack of built-in staking or time limits, betting integrity and the risk of funds being blocked. Their statement is important because it shows that enforcement is becoming more coordinated even though gambling law remains national. It also confirms that “Europe” should not be treated as one uniform market for these products. An operator must assess the law country by country, and a consumer should not assume that availability in one European state means the same service is lawful in another.

France Shows Why Crypto Settlement Does Not Change Gambling Law

France provides one of the clearest examples of how European authorities separate payment technology from the legal nature of the product. In November 2024, the Autorité nationale des jeux, or ANJ, examined Polymarket and considered that its offering could amount to unauthorised gambling under French law. After contact with the operator, geoblocking was introduced to prevent bets from France. The ANJ made an unusually direct point about cryptocurrency: it said its intervention was not based on the fact that transactions were carried out using crypto, but on the broader finding that the offering could constitute unauthorised gambling. That distinction remains highly relevant in 2026. A token, stablecoin or blockchain-based settlement process may change how a transaction is recorded or funded, but it does not replace the legal analysis of the event contract itself.

By February 2026, the French regulator had hardened its public position. The ANJ stated that prediction-market sites were not authorised in France and were considered illegal gambling services. It said that major operators had introduced geoblocking at its request and specifically noted that Kalshi had also implemented such a restriction for France. The same ANJ notice reported that Germany, Belgium, Romania, Switzerland, the Netherlands, Poland, Greece, Cyprus, Ukraine and Portugal had blocked access to Polymarket on the basis that the service offered gambling without the required local licence. The exact legal route differs across countries, but the pattern is consistent: national authorities are willing to treat event contracts as gambling when their local legislation supports that classification, even when the operator describes the activity as trading or forecasting.

France escalated enforcement again in July 2026. On 16 July, the ANJ president ordered French internet service providers to block access to Polymarket after the regulator found that the earlier geoblocking could be circumvented. The ANJ said Polymarket had attracted 578,751 visits and 205,057 unique visitors from France in June 2026, which illustrates why the issue had moved beyond a small specialist audience. The regulator also warned that promoting an unauthorised betting or gambling site, including public dissemination of its odds or payout ratios for promotional purposes, can lead to a fine of €100,000 under French law. For publishers, affiliates and commercial partners, that point is as important as the user-access question. In France, regulatory exposure can arise not only from operating an unauthorised service, but also from helping to promote it.

What the Polymarket and Kalshi Cases Mean for European Users and Operators

The first practical lesson is that home-country regulation does not travel automatically across borders. Kalshi is regulated in the United States by the CFTC as a designated contract market, which gives it a defined legal status there, but that status does not function as a European licence. Polymarket’s crypto-based settlement model creates a different operational structure, yet crypto infrastructure is equally incapable of overriding local gambling or financial law. European regulators look at the activity offered to people in their jurisdiction. For an operator, this means that market access depends on local authorisation, product design and the category into which each contract falls. For a user, it means that statements about being “regulated” should always be followed by a second question: regulated by whom, for which product, and in which country?

Great Britain illustrates another version of the same boundary. In February 2026, the Gambling Commission said that commercial prediction-market products meeting the legal definition of gambling must be licensed and that current prediction-market business models offered in Great Britain would appear likely to fall within the “Betting Intermediary” category, broadly comparable to a betting exchange. The Financial Conduct Authority takes responsibility where the product is a financial-services instrument instead. In its 2026 perimeter material, the FCA said that products linked to non-financial events such as sport or politics fall under the Gambling Commission’s remit, while financial and certain climatic event products can fall within the FCA perimeter. The FCA’s current view is that the financial prediction products it has seen are binary options, whose sale to retail consumers remains prohibited in the UK. Britain therefore reaches a result similar to the EU in principle: the underlying subject and legal form determine the regulator.

For consumers, a sensible compliance check starts with the local regulator rather than with the site itself. The relevant questions include whether the operator appears on an official licence register, whether the specific type of event contract is permitted, whether the service blocks users from countries where it lacks permission, and what complaint or dispute route exists. Identity and age checks, transparent settlement rules, withdrawal procedures and risk controls are also meaningful indicators of whether a service is operating within a recognised framework, although none of them alone proves legality. For businesses, the same logic applies before advertising, sponsorship or affiliate activity begins. A contract that is lawful in the United States or accessible technically from Europe can still be restricted locally. Availability should never be confused with authorisation.

Where Regulation Is Heading After the 2026 Crackdown

The direction of travel in 2026 is towards more co-ordination rather than towards a single European rulebook. The June joint statement from nine European gambling regulators shows a willingness to exchange information, enforcement experience and good practice, especially when major sporting events drive interest in prediction contracts. France’s July blocking action shows that authorities are also prepared to move from warnings and geoblocking requests to direct access restrictions when they consider earlier measures ineffective. This does not mean every European country will classify every prediction contract in the same way. It does mean that an operator cannot safely assume that a cross-border internet business will remain outside national enforcement simply because its contracts are presented in a market format or settled using cryptoassets.

The financial-law side is also becoming clearer. ESMA’s July 2026 intervention tells firms that the existing binary-option framework already covers event contracts that qualify as financial instruments; a new label does not create a new exemption. At the same time, national gambling authorities are asserting jurisdiction over contracts that function as bets. This two-track approach is likely to remain important because prediction markets cover very different subjects. A contract tied to an interest-rate decision, a share-price threshold or another financial measure can raise financial-regulation questions that are not identical to those raised by a contract on a football match or election result. The legal analysis therefore follows the individual contract and its target event rather than treating all prediction markets as one product class.

As of September 2026, the most useful way to understand the boundary is to ignore the cosmetic distinction between a “trade” and a “bet” and focus on substance. Polymarket demonstrates that crypto settlement does not prevent a national gambling authority from classifying an offering as gambling. Kalshi demonstrates that even a federally regulated US event-contract exchange does not receive automatic permission to serve European consumers. ESMA, the ANJ, Britain’s Gambling Commission and the FCA all point in the same broad direction: regulation depends on what the contract represents, how the payout is determined, which customers are targeted and which national rules apply. For users and businesses, that makes local authorisation and product-specific classification more important than marketing language, market charts or payment technology. The legal position can change as regulators issue new decisions, so current official registers and regulator notices remain the strongest reference point for any real-world compliance decision.
