Europe’s Regulator Puts Prediction Markets Under Scrutiny

The European Securities and Markets Authority has sharpened its warning over prediction market access in the European Union, saying major platforms including Polymarket and Kalshi generally do not hold the authorization required to market and sell event contracts to EU users. The message places one of the fastest-growing corners of online trading under closer regulatory examination at a time when event-based contracts have become more visible across politics, sports, crypto prices and macroeconomic outcomes.

Prediction markets allow users to trade contracts tied to future events. In many cases, a contract pays a fixed amount if a specified event happens and pays nothing if it does not. That simple structure can make the products appear straightforward to retail users, but ESMA’s concern is that their legal status can shift depending on how the contracts are designed, marketed and settled. A contract tied to an election outcome, a sporting result, a cryptocurrency price or an economic indicator may not fit neatly into a single regulatory box across the bloc.

ESMA said the marketing and sale of event contracts in the EU generally requires EU authorization, which the largest prediction market platforms currently do not hold. That warning is significant because the EU’s financial regulatory architecture is built around authorization, investor protection, market integrity and cross-border supervision. If a platform is serving users without the necessary approval, regulators may view the activity as an unauthorized service, even when the platform restricts some countries or argues that its products fall outside conventional securities law.

Why Event Contracts Are Legally Complicated

The legal treatment of event contracts depends on the contract itself. ESMA said these products can qualify as financial instruments under EU securities rules. If they are based on distributed ledger technology and are not financial instruments, they may fall under the Markets in Crypto-Assets framework, commonly known as MiCA. In other circumstances, they may be treated as gambling under national law. This means the same broad category of prediction-market activity can trigger different obligations depending on the underlying mechanics and jurisdiction.

Where contracts qualify as financial instruments, ESMA said they generally fall under existing national binary-options measures. Those measures prohibit the marketing, distribution and sale of such products to retail investors. The point is especially relevant because many prediction market contracts resemble all-or-nothing payoff structures, which regulators have historically associated with binary options. For retail users, the simplicity of the payout can mask risks linked to probability pricing, liquidity, event interpretation and platform controls.

Market participants have long debated whether prediction markets should be viewed as information tools, speculative trading venues, gambling products or financial marketplaces. ESMA’s warning signals that, in the EU, the answer may depend less on a platform’s branding and more on the legal characteristics of each contract. That approach could force platforms to assess products contract by contract, rather than treating prediction markets as a single uniform category.

Restricted Jurisdictions Raise Enforcement Questions

ESMA also questioned how major prediction market platforms restrict EU access. Both Polymarket and Kalshi prohibit trading from some EU countries, but ESMA noted that other EU Member States are not included on their restricted lists. The regulator said it is unclear why all EU Member States are not covered, citing risks of unauthorized services and possible breaches of existing retail trading restrictions.

The issue is more than a matter of website wording. In cross-border digital markets, a restricted jurisdiction list is only one layer of compliance. Regulators may also look at onboarding checks, location screening, payment flows, marketing practices and the handling of users who attempt to bypass restrictions. ESMA specifically raised questions about whether platforms can effectively enforce bans on virtual private networks, which can be used to conceal a user’s location.

That concern reflects a broader challenge for online markets. If a platform says users in certain jurisdictions are not allowed to trade, regulators may still ask whether the platform has practical controls to make that restriction meaningful. A compliance notice alone may not satisfy authorities if users can easily access products from prohibited locations. For prediction markets, this creates pressure to demonstrate that location controls, account monitoring and access restrictions operate in practice, not only in policy documents.

National Blocks Add Pressure on Platforms

Several jurisdictions have already moved against prediction market access. In July, France ordered the country’s internet service providers to block access to Polymarket. ESMA pointed to that action alongside blocks or restrictions in Switzerland, Poland, Singapore, Belgium, Portugal, Spain, Brazil and other jurisdictions. The spread of national actions highlights how prediction markets face fragmented but intensifying scrutiny across regions.

The EU’s challenge is that financial regulation, crypto regulation and gambling law can intersect in uneven ways. MiCA provides a bloc-wide framework for crypto-assets, but not every event contract based on distributed ledger technology will automatically be treated the same way. Securities rules may apply where a contract qualifies as a financial instrument. National gambling regimes may apply where the product is classified as wagering. This layered structure leaves platforms exposed to multiple forms of oversight.

ESMA also noted that Europe’s market abuse rules can address misconduct only where contracts fall within the financial regulatory perimeter. That distinction matters because prediction markets can be sensitive to information manipulation, coordinated trading, event wording disputes and attempts to influence outcomes. If a product sits outside the financial perimeter, conventional market abuse rules may not apply in the same way, leaving regulators to rely on other legal tools.

AI Spending Adds a Separate Risk for Crypto

Beyond prediction markets, ESMA also warned about the relationship between technology stocks, artificial-intelligence spending and crypto assets. The regulator said large technology companies are borrowing heavily to fund artificial-intelligence investment, pushing valuations higher and increasing the risk that disappointment or debt pressures could trigger a sell-off in technology shares. In that scenario, large investors may sell riskier and more liquid holdings, including crypto, to raise cash.

The warning does not depend on crypto markets moving in isolation. Instead, it reflects the increasing integration between digital assets and traditional finance. ESMA said crypto is more exposed to this type of shock than in past cycles because spot bitcoin ETFs, bank-issued tokens and institutional custody have tied digital assets more closely to conventional market infrastructure. As a result, stress in one part of the risk-asset complex may transmit more quickly into digital assets than it once did.

Pablo Hernandez, the head of the Bank for International Settlements, stopped short of predicting an artificial-intelligence bubble on Thursday. He did, however, compare the current artificial-intelligence boom to the dot-com boom of the late 1990s, saying that all drew in more capital than eventual returns could justify. His remarks reinforce a broader concern among policymakers that a rush of investment into transformative technology can create financial excess before commercial returns become clear.

Crypto’s Liquidity Can Become a Vulnerability

Crypto assets are often praised for trading around the clock and offering deep liquidity in major tokens. In a market shock, however, liquidity can become a source of vulnerability. If institutions need to raise cash quickly, they may sell assets that are easier to exit, including bitcoin, ether or other widely traded digital assets. That dynamic can create selling pressure even when the initial shock originates outside crypto.

ESMA said stocks bounced back following the escalation of the U.S.-Iran war, but crypto had not yet recovered. The regulator also said bitcoin fell 35% in the first half of 2026, while smaller tokens lost as much as 61%. U.S. spot bitcoin ETFs saw more than $5.5 billion in outflows, while spot ether funds lost nearly $2 billion. Those figures point to a market environment where institutional flows and broader risk sentiment remain crucial for digital-asset pricing.

For crypto investors, the warning is that market structure has changed. Spot bitcoin ETFs can expand access and deepen institutional participation, but they can also transmit risk appetite more directly between traditional portfolios and crypto markets. Bank-issued tokens and institutional custody can improve legitimacy and settlement options, but they also bring digital assets closer to the balance sheets and risk-management decisions of mainstream finance.

What It Means for Traders and Platforms

For prediction market operators, ESMA’s warning increases the importance of authorization analysis, jurisdictional controls and product classification. Platforms may need to examine whether specific event contracts qualify as financial instruments, crypto-assets under MiCA, or gambling products under national law. They may also face pressure to explain why some EU countries are restricted and others are not.

For traders, the practical implication is that access to prediction markets in Europe may become more uneven or more heavily restricted. Even where platforms remain accessible, users could face stricter onboarding, enhanced location verification or product limitations. Market participants should also recognize that regulatory status can affect contract availability, platform operations and dispute handling.

For crypto markets, ESMA’s broader risk warning places technology-sector valuations and artificial-intelligence spending firmly on the watchlist. Digital assets remain influenced by internal factors such as network activity, token supply, ETF flows and exchange liquidity. But the regulator’s framing emphasizes that crypto now sits more visibly within the global risk-asset ecosystem, where shocks from technology shares, credit conditions or institutional deleveraging can matter quickly.

FXCOINZ will continue monitoring how European regulators approach prediction markets and how potential technology-sector stress could affect digital assets. The key takeaway is that regulatory perimeter questions and macro-financial risks are converging. Prediction markets face scrutiny over authorization and retail protection, while crypto faces the possibility that a sell-off in artificial-intelligence-linked technology stocks could prompt investors to reduce exposure to liquid digital assets.

Frequently Asked Questions (FAQs)

What did ESMA say about Polymarket and Kalshi?

ESMA warned that major prediction market platforms including Polymarket and Kalshi generally lack the authorization required to market and sell event contracts to EU users. The regulator said this creates concerns around unauthorized services and retail trading restrictions.

What are prediction market event contracts?

Prediction market event contracts let users trade on whether a future outcome will occur. These outcomes can involve elections, sports, cryptocurrency prices or economic events, and contracts typically pay a fixed amount if the outcome happens and nothing if it does not.

Why could event contracts fall under EU financial rules?

Event contracts may qualify as financial instruments depending on their structure. Where they do, ESMA said they generally fall under existing national binary-options measures that prohibit marketing, distribution and sale to retail investors.

Could MiCA apply to prediction markets?

MiCA may apply where event contracts are based on distributed ledger technology and are not financial instruments. ESMA’s position is that the legal treatment depends on the specific contract and how it is structured.

Why is ESMA concerned about restricted jurisdiction lists?

ESMA noted that some platforms restrict trading from certain EU countries while leaving others off their restricted lists. The regulator questioned why all EU Member States are not included and raised concerns about whether platforms can effectively block users who use virtual private networks.
