ESMA names prediction markets a systemic risk in twice-yearly report

In April, a U.S. soldier named Gannon Ken Van Dyke placed wagers on Polymarket ahead of a raid targeting Venezuelan leader Nicolás Maduro. He earned a significant profit. He pleaded not guilty to insider trading charges. ESMA, in its latest risk report, uses that case as an illustration of something it believes is structural rather than exceptional.

The report, issued as part of ESMA's twice-yearly market surveillance, describes prediction markets as environments where manipulation and insider trading risks "reach new levels," particularly on platforms with limited identity verification. The language is careful but the direction is not. This is a watchdog moving from observation to position.

What ESMA is doing, specifically, is building a record. Twice-yearly risk reports are not enforcement instruments. They are the documentation that precedes enforcement instruments. The Van Dyke case gives the report a named incident with a charged defendant; the broader language about "gamified structure," "social media-driven promotion," and exploitation of retail investors gives regulators across EU member states a shared vocabulary to work from. Malta is already exploring a framework. The FCA in the UK is reviewing retail access rules, though it has previously described its binary options ban as appropriate given what it calls the "gambling-like nature" of such contracts — language that tells you where the institutional prior sits.

Polymarket has joined Blockchain for Europe, a Brussels-based trade association, and its Chief Legal Officer has said the company is committed to engaging "early and openly" with EU policymakers. That is a real strategic shift. Whether it is fast enough is a different calculation. Regulatory calendars in Brussels do not move on a startup's timeline, and ESMA naming your product category in a systemic risk report is not a conversation opener — it is a constraint being written into the record before the conversation begins.

The mechanism I keep returning to is this: Polymarket and Kalshi are both building toward European legitimacy at the same moment the European regulatory apparatus is formalizing its skepticism. Kalshi is already in the Ninth Circuit and petitioning for en banc review in Nevada. Its European ambitions, which co-founder Luana Lopes Lara described publicly in July, now sit behind a longer queue. ESMA's report does not create a legal barrier by itself, but it makes the first authorized EU framework materially harder to negotiate on favorable terms. Any member state that moves to license prediction markets after this report will be doing so against the documented position of the continental watchdog.
