Prediction Markets Surge Amid EU Regulatory Concerns

The rise of prediction markets is transforming the landscape of speculation and forecasting, evolving into a multibillion-dollar industry despite regulatory hurdles in the European Union. In 2025, platforms like Polymarket and Kalshi have collectively handled over $37 billion (€31.5 billion) in wagers, showcasing their growing significance in predicting real-world events, particularly in finance and media.

Prediction markets allow users to place bets on the outcomes of uncertain future events, with the market price reflecting the collective belief about what is most likely to occur. For instance, rather than conducting traditional surveys or polls to gauge public opinion on an election outcome, participants can invest money in their predictions. This dynamic real-time forecasting mechanism is often viewed as more reliable than conventional polling methods.

Significant financial interest from major institutions further underscores this trend. Recently, Kalshi secured a $1 billion (€850 million) Series E funding round, valuing the platform at $11 billion (€9.4 billion). Meanwhile, Polymarket received a strategic investment of up to $2 billion (€1.7 billion) from the Intercontinental Exchange (ICE), which valued it at $8 billion (€6.8 billion). This investment includes ICE’s role as the distributor of Polymarket’s data to institutional investors globally.

Regulatory Challenges in the EU

Despite the success of prediction markets, many EU countries remain hesitant, leading to a fragmented regulatory environment. The EU’s approach contrasts sharply with the growing acceptance of these platforms in other regions. For instance, the French National Gaming Authority blocked Polymarket in late 2024, ruling it as unlicensed gambling. Subsequently, similar bans were enacted in Belgium, Poland, and Italy. In Romania, the National Gambling Office blacklisted Polymarket after it hosted wagers on the country’s 2025 presidential election, where the trading volume surpassed $600 million. The Office emphasized that any betting on future outcomes requires licensing, regardless of the currency used.

On the other hand, countries like Germany and Spain continue to permit access to prediction markets, highlighting the regulatory divide within the EU. As the EU prepares for the full implementation of the Markets in Crypto-Assets (MiCA) regulation in July 2026, prediction markets utilizing blockchain technology will need to navigate stringent compliance requirements. The European Securities and Markets Authority has indicated that MiCA will impose strict market abuse regulations on any prediction market that uses crypto assets.

The Impact of Prediction Markets on Media and Society

The relevance of prediction markets has gained traction, especially following significant events like the 2024 US presidential election and the 2025 German snap election. These platforms acted as real-time scoreboards, often delivering predictions that rivaled traditional polls in accuracy. This perceived reliability has prompted legacy media outlets to adapt their reporting practices. Recently, CNN partnered with Kalshi to incorporate live prediction market data into its broadcasts, while CNBC announced a similar initiative shortly thereafter.

Nevertheless, the gamification of prediction markets has raised concerns. Critics argue that it blurs the line between serious forecasting and high-stakes gambling, potentially leading to “hyper-commodification” of social outcomes. Such commodification can encourage gambling behaviors and create opportunities for insider trading, undermining the integrity of these platforms.

In a notable incident, a trader on Polymarket, known as “AlphaRaccoon,” drew attention after winning 22 out of 23 bets related to Google’s 2025 Year in Search rankings, netting over $1 million (€850,000) in just 24 hours. Accusations surfaced suggesting that this trader may have had insider access to proprietary search data, raising alarms about the potential for manipulation within prediction markets.

In October, Brian Armstrong, CEO of Coinbase, highlighted the risks of outcome manipulation during a third-quarter earnings call. Users on Polymarket and Kalshi placed significant bets on whether Armstrong would use certain buzzwords during the call. When he paused to emphasize these terms, the implied probability of their mention surged from approximately 15% to 100%. Armstrong later characterized the moment as “spontaneous,” yet it illustrated the vulnerability of prediction markets to manipulation, which could jeopardize their role as neutral forecasting tools.

As the landscape of prediction markets continues to evolve, the EU faces a critical decision: to engage with this burgeoning industry or enforce outright bans. The outcomes of these discussions will shape the future of speculation and collective forecasting in Europe and beyond.
