The European Securities and Markets Authority (ESMA) has raised a regulatory alarm over the deepening links between crypto-assets and traditional finance, warning that tokenized equities, decentralized finance exploits, and prediction platforms could amplify systemic risks. In its semi-annual risk monitoring report published on September 10, 2026, the EU securities regulator urged supervisors to track transmission channels more closely.
ESMA said outstanding tokenized equities reached approximately €1.9 billion at the end of June 2026, up from roughly €0.3 billion at the end of 2024—a 6.5-fold increase in eighteen months. Most activity involved wrapped products tied to large U.S.-listed technology companies. The watchdog cautioned that blockchain transfers often do not convey legal ownership, and multiple tokens tracking the same share may fragment liquidity and weaken price discovery under stress.
The report also highlighted risks from DeFi protocol exploits and smart contract failures, warning that automated execution and immutability can make erroneous transfers difficult to reverse. While ESMA did not claim crypto currently poses a systemic threat to the EU financial system, it said programmable securities could increasingly connect stock-linked assets to DeFi collateral and other on-chain transactions.
Prediction markets drew separate scrutiny. ESMA reported quarterly volume of approximately $12 billion on Polymarket and $8.8 billion on Kalshi during Q4 2025. It said pseudonymous trading can hinder detection of insider dealing, wash trades, and coordinated manipulation, citing reports that newly created wallets earned $1.2 million shortly before the February U.S.-Israeli strikes on Iran became public. The regulator also noted French weather service Météo-France filed a police complaint over suspected sensor interference linked to Polymarket weather markets.
ESMA Chair Verena Ross said, “Investor optimism continues to support elevated valuations despite rising geopolitical tensions and a weakening economic outlook.” She warned that an abrupt correction could follow if sentiment changed or economic risks materialized. The regulator kept market, contagion, and operational risks at its highest classification, noting crypto prices had erased nearly €2 trillion in market value since their October peak.
The warning coincides with U.S. legal battles over prediction markets. The Commodity Futures Trading Commission (CFTC) is litigating against state authorities in Kentucky, Minnesota, New Mexico, New York, Illinois, and Connecticut over whether event contracts should be federally regulated derivatives or state gambling products. On September 2, 2026, New Jersey asked the U.S. Supreme Court to determine whether state regulations retain authority over CFTC-registered markets.
In related developments, Nasdaq agreed to invest $100 million in Kraken parent Payward, with Nasdaq Equity Tokens planned for a second-quarter 2027 launch. The SEC has also proposed recognizing blockchain databases as official securities ownership records, with public comments open for 60 days.
