ESMA Flags Rising Crypto Links as a Potential Risk to TradFi

Europe’s top securities regulator is urging closer surveillance of how crypto markets are increasingly intertwined with traditional finance, warning that vulnerabilities in digital-asset ecosystems could contribute to wider financial-system shocks.

In a risk monitoring report published Thursday, the European Securities and Markets Authority (ESMA) highlighted the “growing linkage between increasingly vulnerable crypto-asset markets and the broader financial system,” pointing to both new forms of market integration and specific activity it says can amplify contagion risk.

Key takeaways

• ESMA warns crypto-to-traditional finance links may help shocks spread as crypto activity becomes more connected to mainstream market infrastructure.
• Tokenized equities remain small globally but are gaining traction in Europe, potentially changing who participates and how markets are structured.
• DeFi exploits are on ESMA’s radar as another channel through which crypto disruptions could spill into the wider system.
• Prediction markets are flagged as an emerging concern, with particular focus on insider trading, wash trading, and coordinated manipulation.
• The US regulatory fight over prediction markets continues and could ultimately be settled by the US Supreme Court.

Crypto’s growing connection to traditional markets

ESMA’s warning centers on the possibility that vulnerabilities concentrated in crypto markets could be transmitted into the broader financial system—especially as adoption broadens beyond purely crypto-native venues.

The regulator singled out two developments that could deepen these connections: increased interest in tokenized equities and ongoing risks tied to decentralized finance (DeFi).

On tokenized equities, ESMA stressed that their scale is still negligible relative to global stock markets. However, the report argues that even small segments can matter if they begin pulling in new participants, infrastructure, and liquidity pathways that are shared with, or tightly linked to, mainstream markets.

In DeFi, ESMA pointed to the continued occurrence of exploits—an area that can trigger rapid losses, liquidations, and liquidity stress. While ESMA did not claim direct causal links in every case, its broader message was clear: as crypto mechanisms intersect more frequently with traditional systems, risk events may no longer stay contained within crypto.

Prediction markets: harder enforcement, new compliance challenges

Among ESMA’s most notable emerging flags is the growing use of prediction markets. The regulator said concerns could intensify around insider trading and market manipulation, especially when crypto tools are involved.

ESMA’s report indicates that crypto use in prediction-market activity can complicate detection of problematic conduct such as wash trading and coordinated manipulation. The issue is not only who trades, but how activity is routed and recorded—factors that can affect the visibility regulators have into trading intent and coordination.

The warning matters for traders and market operators because enforcement often depends on the practical ability to identify patterns quickly and attribute them to individuals or entities. If crypto mechanics reduce the clarity of market surveillance, regulators may face higher compliance burdens and potentially stricter controls as authorities react.

US jurisdiction battle over event contracts

ESMA’s European concerns arrive as prediction markets in the United States face a separate, but related, regulatory struggle over what rules apply. The core disagreement is whether event contracts are treated as federal derivatives or fall under state gambling frameworks.

According to ESMA’s report context, the Commodity Futures Trading Commission (CFTC) has issued guidance for prediction markets throughout 2026, while defending what it says is its exclusive jurisdiction over federally regulated event contracts.

That position has been tested in court. The CFTC has sued multiple states—including Kentucky, New Mexico, Illinois and Connecticut, and Minnesota—after those authorities attempted to apply state gambling laws to prediction market operators.

ESMA’s warning about manipulation and insider trading sits in the middle of this broader policy tension: if legal categories remain contested, compliance requirements can differ sharply depending on how a court characterizes the underlying instrument.

The dispute could also reach the US Supreme Court. On September 2, New Jersey officials petitioned the court to decide whether states may enforce sports gambling laws against prediction markets registered with the CFTC. The officials cited ongoing litigation across at least 20 states.

Whether the Supreme Court will accept the case remains uncertain, but a ruling—if it occurs—could materially affect how market operators structure products and how regulators allocate oversight authority.

What investors and builders should watch next

ESMA’s report is a reminder that regulators are tracking not only crypto trading activity, but also how crypto-native products could plug into mainstream financial plumbing. The next question for investors and market participants is whether measures meant to protect traditional markets will keep pace with fast-evolving crypto linkages—particularly in areas ESMA highlighted, such as tokenized equities, DeFi exploits, and prediction markets.

As enforcement and jurisdiction battles continue—especially in the US—readers should watch for updates to surveillance expectations, compliance requirements, and how courts ultimately define the legal category of prediction-market contracts.
