When will Finland first adopt or bring into force legislation, an official regulatory decision, or an enforcement measure that specifically targets prediction markets (e.g. Polymarket, Kalshi-style event contract platforms)?

To answer the underlying question—Kohdistetaanko ennustemarkkinoihin sääntelyä Suomessa vuoteen 2030 mennessä?—there is roughly a 60% probability that Finland will adopt a qualifying measure explicitly targeting prediction markets by the end of 2030. As of October 2026, no Finnish authority has issued a law, binding decision, or enforcement measure that specifically names prediction markets or event-contract platforms 3 sources. Current usage of platforms like Polymarket and Kalshi in Finland remains marginal, and they are currently broadly considered a legal "grey area" 2 sources.

The most significant domestic variable is Finland's transition away from the Veikkaus monopoly to a licensing model. Parliament approved the new Gambling Act in December 2025, and the licensed market will open on July 1, 2027 2 sources. While this new framework bans betting on elections and financial markets—which directly conflicts with Polymarket's core offerings—the legislation is entirely generic and does not explicitly name event contracts or prediction markets 2 sources. Consequently, the launch of the licensing regime alone will not count as explicit regulation. However, the handover of supervisory authority from the National Police Board to the new Licensing and Supervision Agency (Lupa- ja valvontavirasto) in July 2027 establishes a fresh regulatory venue with prohibition-decision powers 2 sources, setting the stage for specific interpretive rulings.

External pressure from European regulators makes an eventual explicit action highly plausible, driving the median date estimate to mid-to-late 2029. Regional peers, including Denmark, France, Spain, Germany, and the Netherlands, have already blocked, banned, or blacklisted these platforms throughout 2025 and 2026, often actively classifying them as illegal gambling 55 sources. Furthermore, the EU securities regulator (ESMA) stated in July 2026 that event contracts on financial underlyings qualify as derivatives under MiFID II 2 sources. This provides Finland's Financial Supervisory Authority (Finanssivalvonta) with a ready-made legal basis to issue an explicit warning or enforcement action.

Despite this momentum, there is a substantial chance (~40%) that a qualifying regulatory action slips beyond 2030. The new regulatory agency will be heavily absorbed by the complexities of the 2027 licensing transition, and Finland lacks immediate DNS or payment blocking powers in the initial reform package; follow-up legislation on blocking is not expected to be assessed until 2028–2030 intermin.fi. There is also a distinct possibility that future enforcement against these platforms remains strictly generic—targeting them merely as "unlicensed operators" without ever issuing the explicit classification or naming convention required. Finally, if platforms voluntarily geoblock Finland in response to broader EU pressure, Finnish authorities may never feel compelled to act.
