EU curbs prediction markets

Highlights

ESMA clarified that certain prediction-market event contracts sold to retail clients fall under the EU binary options ban if classified as financial instruments under MiFID II.
Kalshi's $22 billion valuation and Jump Trading's investments in both Kalshi and Polymarket highlight growing deal activity as prediction markets expand across finance and crypto sectors.
EU firms offering event-linked investment services require MiFID II authorization, and some contracts may also trigger national gambling laws or MiCA compliance, increasing regulatory complexity.

ESMA sets compliance line for event contracts

As reported by Coindesk, citing ESMA, some prediction-market event contracts fall under the EU ban on binary options when they meet the definition of financial instruments and are marketed, distributed or sold to retail clients.

The regulator says these products typically offer a binary payout, usually a fixed amount or nothing, based on the outcome of a future event. It adds that a product's commercial label does not determine its legal status, meaning an "event contract" can still qualify as a derivative under MiFID II if its underlying fits derivatives categories.

ESMA also says that adding a coupon, reward or interest-like payment on client funds does not alter the product's binary structure. Firms must assess classification based on the contract's features and functioning, not on branding or presentation.

Broader implications for crypto and finance platforms

The guidance comes as prediction markets expand across both crypto and traditional finance, with business models increasingly overlapping among exchanges, brokerages and sportsbooks. The sector has also drawn deal interest, with Kalshi and Polymarket discussed as potential M&A targets as operating boundaries continue to blur.

Kalshi was valued at $22 billion in its latest funding round, while Jump Trading has moved to take small stakes in Kalshi and Polymarket in exchange for liquidity provision. ESMA says firms offering investment services linked to such products in the EU need MiFID II authorization even when distribution is limited to non-retail clients.

The regulator adds that some event contracts may also be subject to national gambling laws or, if tokenized and not classified as financial instruments, to the bloc's Markets in Crypto-Assets, or MiCA, framework. That leaves operators facing overlapping compliance tests as EU authorities focus on how these contracts work in practice.

In our earlier article on European regulators’ growing scrutiny of AI in finance, we outlined warnings from policymakers that rulemaking is struggling to keep pace with agentic systems entering trading, operations, and risk management. We also highlighted concerns that autonomous models could amplify volatility in stress periods, prompting discussion of safeguards such as circuit breakers or kill switches to protect market integrity.
