Prediction Market Polymarket Runs into Regulatory Trouble in Romania

Cryptocurrency-powered betting platforms just hit another speed bump in Europe. Romania’s National Office for Gambling (ONJN) made headlines by placing Polymarket, the leading prediction market platform, on its official blacklist of unauthorized gambling websites. This move might seem like just another regulatory action in an increasingly crowded field, but it tells a much bigger story about how governments worldwide are drawing a line between innovation and compliance.

Understanding What Polymarket Does and Why It Matters

Polymarket has become a household name among crypto enthusiasts and traders worldwide. At its core, the platform allows users to place bets on real-world events, from political elections to sports outcomes and economic forecasts. What makes it different from traditional betting sites is its reliance on blockchain technology and cryptocurrency for transactions. The platform describes itself as an “event trading platform” rather than a betting operation, arguing that it’s more akin to a financial exchange where people trade contracts on future outcomes.

The distinction might seem like semantics, but it’s actually central to the entire regulatory conflict. Users on Polymarket purchase virtual shares representing “yes” or “no” outcomes on various events. If their prediction comes true, they profit. If it doesn’t, they lose their stake. The platform charges a small commission on each transaction, taking a slice of the action regardless of the outcome. During the 2024 U.S. presidential election alone, Polymarket facilitated over $3 billion in trading volume, demonstrating its significant reach and influence in the prediction markets space.

Romania Takes Action: What Led to the Ban

The ONJN’s decision to blacklist Polymarket didn’t happen in a vacuum. During Romania’s recent electoral period, the platform saw explosive growth in trading activity. Regulators estimated that users placed over $600 million in wagers during the presidential elections alone. More immediately, the Bucharest local elections saw another $15 million in trading volume on prediction contracts specifically related to the mayoral race. This concentrated activity during politically sensitive moments particularly concerned authorities.

Vlad-Cristian Soare, the President of the ONJN, made the regulator’s position crystal clear. “The decision to include Polymarket on the blacklist is not related to technology, but to the law,” he stated. This emphasis is crucial because it signals that the regulatory concern isn’t about blockchain technology itself, but rather about the actual activity taking place on the platform. According to the ONJN’s interpretation, when someone bets money on a future outcome, whether in traditional currency or cryptocurrency, it constitutes gambling that requires proper licensing.

The Romanian regulator drew a sharp distinction between what Polymarket claims to be and what it actually does. While the platform markets itself as “event trading,” the ONJN classified its operations as “counterparty betting.” This is the key difference: in counterparty betting, users essentially bet against each other, with the platform taking a commission. The ONJN argued that allowing platforms to rebrand counterparty betting as “trading” would set a dangerous precedent, enabling operators to evade both gambling regulations and financial market rules. The regulator warned that such a precedent could allow operators to classify themselves as legitimate traders while bypassing the licensing framework that governs financial institutions.

The Broader Context of Romania’s Gambling Laws

To understand why Romania took this action, it helps to know how the country approaches gambling regulation more broadly. Romania maintains a licensing system for gambling operations, administered through the ONJN under the Ministry of Finance. The framework is fairly comprehensive, covering online gambling, sports betting, and traditional games of chance.

Gambling activity in Romania can only proceed legally with a license and authorization from the ONJN. The country has established two main license classes: Class 1 for operators offering gaming services directly to consumers, and Class 2 for business-to-business operators, including payment processors and affiliates. Payment service providers handling gambling transactions must also hold a Class 2 license, and funds from players must be held exclusively in bank accounts within Romanian territory.

Romania’s regulatory approach reflects a balance between allowing regulated commercial gambling while protecting against unlicensed operators. Internet service providers in the country receive blacklists of unauthorized platforms and must block access within 15 days. When users attempt to access blacklisted sites, they’re redirected to an official ONJN page explaining the restriction. The ONJN maintains a publicly accessible register updated daily showing all licensed and authorized operators, providing transparency to consumers about which platforms are legitimate.

The consequences for violating these rules are serious. Conducting gambling activities without proper authorization constitutes a criminal offense, carrying potential imprisonment and substantial fines. The regulator also emphasizes that both operators and users face potential penalties for participating in unlicensed gambling activities, whether they’re advertising, promoting, or simply using the platforms. Participation in unlicensed gambling is classified as a misdemeanor under Government Emergency Ordinance 77/2009.

How Europe Approaches Prediction Markets

Romania didn’t pioneer the idea of treating prediction markets as gambling. In fact, it became the fourth European country to formally restrict Polymarket, joining Belgium, France, and Poland in taking enforcement action.

France was the first to move, beginning in late 2024 when the country’s gambling regulator, the Autorité Nationale des Jeux (ANJ), initiated an investigation. The trigger was a massive betting spree during the 2024 U.S. presidential election. A single French trader, known as Théo, reportedly placed over $30 million in wagers on Donald Trump’s victory across multiple accounts. The incident prompted the ANJ to conclude that Polymarket was operating as an unlicensed gambling platform under French law, regardless of its use of cryptocurrency. The platform voluntarily blocked French users in November 2024, preventing them from accessing trading functions, though some users reported success using VPNs to circumvent the restrictions.

Belgium took action in early 2025, with its gambling regulator, the Kansspelcommissie, formally blacklisting Polymarket after the platform failed to respond to three separate regulatory warnings. Following this decision, the authorities requested a public prosecutor to block IP access, effectively preventing Belgian users from reaching the platform. Poland’s Ministry of Finance added Polymarket’s domain to its Register of Illegal Gambling Domains around the same time, enforcing internet service provider and payment processor restrictions against the platform.

Singapore and Thailand also joined the enforcement trend in early 2025, with Singapore imposing penalties of up to $10,000 in fines or six months imprisonment for users accessing the platform, and Thailand’s authorities proposing formal restrictions. Taiwan had previously taken similar action in 2023, even prosecuting users for placing bets on Polymarket.

The Cryptocurrency and Gambling Convergence

The tension over platforms like Polymarket reflects a fundamental challenge in modern regulation. The European Union has no sector-specific legislation governing gambling services, leaving individual member states to establish their own frameworks. Most EU countries allow at least some forms of internet gambling, though approaches vary widely. Some nations maintain state monopolies on gambling, while others operate licensing systems allowing multiple operators.

This decentralized regulatory landscape creates complications for crypto-based platforms. When Polymarket argues that its structure is fundamentally different from traditional betting because it uses blockchain and cryptocurrency, European regulators largely dismiss this reasoning. They contend that the technology used for settlement is irrelevant to the core question: Are users risking money on uncertain outcomes? If yes, then it’s gambling and must be regulated accordingly.

The ONJN emphasized this point in its enforcement action, noting that blockchain infrastructure cannot exempt platforms from normal gambling licensing requirements. The regulator expressed particular concern about Polymarket’s lack of consumer protection mechanisms, anti-money laundering procedures, and tax reporting capabilities. These safeguards exist precisely because regulators consider prediction markets to be gambling products requiring the same protections as casinos or sportsbooks.

Polymarket’s Challenges Beyond Romania

The battles with European regulators represent just one front of Polymarket’s ongoing regulatory struggles. In the United States, the platform faces a more complex landscape due to the division of authority between federal and state regulators.

In 2022, the U.S. Commodity Futures Trading Commission (CFTC) fined Polymarket $1.4 million for operating derivatives markets without proper registration. The platform was forced to cease operations for U.S. residents and citizens. However, the company has since attempted a comeback strategy by acquiring QCEX, a Florida-based exchange holding a CFTC license. This acquisition gives Polymarket regulatory cover to resume U.S. operations under federal derivatives rules.

Kalshi’s Battle with State Regulators

Yet state regulators aren’t necessarily satisfied with federal approval. Kalshi, a competing prediction market platform that also operates under CFTC authority, has faced significant legal challenges from state gambling regulators. In 2025, New York’s State Gaming Commission issued a cease-and-desist letter against Kalshi, arguing that its event contracts constitute illegal sports wagering under state law. Kalshi responded by filing a federal lawsuit, arguing that state gambling regulations are preempted by the federal Commodity Exchange Act. The company contended that New York’s actions intrude upon the federal government’s exclusive authority to regulate derivatives trading on CFTC-supervised exchanges.

Kalshi’s legal filings emphasized that allowing states to regulate its activities would create a patchwork of conflicting state laws, precisely the chaos Congress sought to prevent when establishing the CFTC. The company stated that it was trapped between complying with New York’s order, which would violate CFTC rules and threaten its legitimacy, or defying the state, which would invite civil and criminal penalties.

Federal courts in Nevada and New Jersey have previously ruled in Kalshi’s favor on similar disputes, suggesting ongoing litigation over this jurisdictional question. These state battles mirror Polymarket’s experience internationally, where different regulatory regimes clash over authority and classification.

A Global Divide on Financial Derivatives and Betting

The regulatory response to prediction markets ultimately reflects broader disagreement over how to categorize these platforms. The United States leans toward viewing them as financial derivatives that fall under commodity trading rules rather than gambling statutes, at least at the federal level. Europe generally categorizes them as gambling, particularly when real money is at stake on uncertain outcomes.

This divide explains why Polymarket faces such different regulatory environments across jurisdictions. In Canada, for instance, binary options contracts shorter than 30 days are prohibited, with regulators labeling them investment fraud due to their high-risk nature and unsuitability for retail investors. The Canadian Securities Administrators determined that binary options represent the leading type of investment fraud facing Canadians, justifying their outright prohibition.

Polymarket’s attempt to launch a U.S. comeback through the licensed QCEX exchange initially focused on sports betting in high-profile markets like the NFL and NBA. The company received what CFTC officials called a “no-action letter,” indicating the agency doesn’t plan enforcement action if Polymarket stays within defined compliance boundaries. However, this federal approval doesn’t automatically resolve battles with state regulators or address the international enforcement actions.

What This Means for the Future of Prediction Markets

The coordinated regulatory response across multiple countries signals a clear message: prediction markets will face mounting scrutiny and restriction unless they obtain proper licensing in each jurisdiction. Romania’s decision joins an expanding pattern of enforcement that leaves limited room for platforms to operate as global services outside regulatory frameworks.

For Polymarket and similar platforms, this reality requires significant adaptation. The company must either pursue licensing agreements in each country where it operates, restrict access to jurisdictions with favorable regulatory treatment, or develop compliance infrastructures that satisfy the requirements of multiple regulatory regimes. Each option comes with significant operational and financial costs that could fundamentally reshape the prediction market business model.

The broader prediction market industry now faces questions about its long-term viability in a world of tightening regulations. While platforms like Polymarket argue they offer valuable tools for forecasting and price discovery, regulators across multiple continents view them as primarily gambling products requiring conventional oversight. Until there’s broader regulatory consensus on how to treat prediction markets, expect more blacklists, more enforcement actions, and more jurisdictions following the path that Romania has taken.
