EU Regulator Warns Many Prediction Markets Are Off-Limits to Retail Investors

Under the EU's Markets in Financial Instruments Directive (MiFID II), many event contracts may qualify as binary options. Binary options have been restricted from sale to retail investors across the bloc since 2018, a measure introduced amid concerns about investor protection and the speculative nature of the products.

ESMA stated that event contracts qualifying as financial instruments are derivatives and fall within the scope of temporary product intervention measures on binary options, which were initially adopted through ESMA Decision (EU) 2018/795. Those temporary measures were later replaced by permanent national measures that mirror the original ESMA rules. As a result, the marketing, distribution or sale to retail clients of event contracts meeting the definition of financial instruments is prohibited, according to the regulator's statement.

ESMA emphasised that the assessment turns on the legal classification of each individual contract rather than a blanket categorisation of a platform or product type.

Why It Matters for the Corridor

The warning signals heightened regulatory attention toward platforms offering event-based financial products, a fast-growing category that has drawn users globally. For operators and investors linking African and European markets, the guidance underlines that products offered to retail clients in the EU must comply with the bloc's existing derivatives rules, regardless of how they are branded.

The development in Europe follows regulatory action elsewhere. As noted by BitKE, Brazil moved to block 27 prediction markets, including Polymarket and Kalshi, reflecting a broader pattern of authorities examining how event-based trading products fit within existing financial frameworks.

ESMA's statement does not amount to a new ban but rather clarifies how current EU rules apply. Firms operating in or targeting the European market will need to evaluate whether their offerings meet the definition of financial instruments and, if so, ensure they are not marketed to retail investors in breach of the standing restrictions.
