Prediction markets are absolutely exploding right now. The platform Kalshi recorded a record transaction volume of $9 billion in June 2026, driven by the World Cup and the growing excitement surrounding the US midterm elections. But this meteoric growth is attracting the attention of regulators on both sides of the Atlantic Ocean, who are preparing unprecedented restrictions on the industry.
Volume Multiplied by 10 in One Year
In June 2025, Kalshi handled less than $1 billion in monthly volume. One year later, that figure has been multiplied by ten to reach $9 billion. This dizzying growth can be explained by several converging factors: the 2026 World Cup has generated unprecedented enthusiasm for sports betting through prediction markets, the US midterm elections are fast approaching, and mainstream adoption of prediction platforms has crossed a decisive milestone for the industry.
Kalshi CEO Tarek Mansour stated that the platform has surpassed one million monthly active users, a figure that stood at just 200,000 only six months ago. “Prediction markets are becoming the social network of information,” he said during a recent interview. “People no longer just want to consume the news — they want to bet on it and express their opinion in an engaging and interactive way.”
Europe Issues a Stern Warning
While Kalshi is racking up impressive volumes, the European Securities and Markets Authority (ESMA) has issued a stern warning regarding the risks of prediction markets for retail investors. ESMA considers that these platforms are akin to gambling products disguised as financial instruments and is preparing a restrictive regulatory framework that could block European retail investors’ access to American prediction markets altogether.
The European position aligns with MiCA (Markets in Crypto-Assets Regulation), which aims to strictly regulate digital assets and associated derivative products. Blockchain-based prediction markets, such as Polymarket, are particularly in the crosshairs of European regulators who view them with increasing suspicion and concern.
BitMart US Launches a Regulated Offering
Paradoxically, while Europe tightens the screws, BitMart US has announced the launch of regulated prediction products on the American market. This initiative, overseen by US regulators, illustrates the growing divergence between the regulatory approaches of the two continents. Where Europe prefers to restrict and clamp down, the United States seems to lean toward progressive oversight that allows innovation to flourish further.
This divergence is particularly notable as the CLARITY Act, which aims to clarify the US regulatory framework, saw law enforcement withdraw their opposition last week. The US regulatory environment is gradually becoming more favorable toward digital assets and associated products, creating a notable contrast with European attitudes on the matter.
Kalshi Faces Legal Battles
Despite its commercial success, Kalshi is not immune to legal challenges. The platform faces lawsuits in several US states that contest the legality of its election prediction markets. The attorneys general of five states have filed legal petitions arguing that these markets constitute a form of unregulated gambling that should be subject to state oversight and control.
The legal debate is complex: the US Commodity Futures Trading Commission (CFTC) initially approved Kalshi’s prediction markets by classifying them as regulated futures contracts. But several states are contesting this classification, arguing that these markets circumvent their gambling laws and operate outside appropriate regulatory boundaries entirely.
Polymarket and the Blockchain
On the decentralized side, Polymarket continues to dominate the blockchain prediction market sector, with a volume exceeding $1.5 billion in June. The Polygon-based platform benefits from the anonymity and censorship resistance that blockchain technology offers, but this also makes it more vulnerable to potential regulatory crackdowns. ESMA explicitly mentioned decentralized platforms in its warning about industry risks to investors.
The contrast is striking: on one hand, Kalshi, a centralized and regulated platform, explodes in volume entirely legally; on the other, Polymarket, a decentralized platform, thrives in a regulatory gray zone. Both business models could be threatened if the current restrictive regulatory trend continues and gains momentum across multiple jurisdictions simultaneously.
What Future for Prediction Markets?
Prediction markets are at a historic crossroads right now. On one hand, mainstream adoption is exploding with record volumes and use cases that go far beyond simple sports betting: elections, economic results, commodity prices, the price of Bitcoin. On the other hand, regulators are multiplying warnings and preparing restrictions that could stifle the industry before it even reaches its full potential as a market.
The fundamental question remains: are prediction markets a legitimate financial tool that improves the accuracy of collective forecasting, or a disguised form of gambling that exploits users’ cognitive biases? The answer to this question will determine the fate of an industry that now weighs nearly $10 billion per month in transaction volume across all platforms.
In the meantime, investors and traders must closely monitor regulatory developments in the coming weeks. ESMA is expected to publish its final framework by September 2026, while US legal battles could extend well into 2027. One thing is certain: the fight between innovation and regulation is just beginning, and its final outcome will shape the industry for years to come.
