The Ministry’s Directorate General for Gambling Regulation is direct about its reasoning. Prediction markets allow users to bet money on uncertain future outcomes. Under Spanish law, that qualifies as gambling, and gambling operators require an administrative license that neither Polymarket nor Kalshi holds.
Beyond the licensing gap, regulators identified specific consumer protection failures. Licensed gambling operators in Spain must implement age verification systems, access controls for minors, self-exclusion mechanisms for problem gamblers, and ongoing user monitoring. The ministry determined that both platforms lack these safeguards entirely.
The timing adds political dimension. Polymarket recently opened a market on the possible early end of Prime Minister Pedro Sánchez’s term. Kalshi currently offers bets on which national leader will leave office in 2026, with Sánchez listed at 29% probability. Both markets generated attention on Spanish social media. It is attracting regulatory scrutiny that might otherwise have moved more slowly.
A Pattern Forming Across Borders
Spain is not acting in isolation. Brazil blocked both platforms earlier this year as part of a broader crackdown on prediction markets. That was operating without gambling compliance. Indonesia blocked Polymarket last week after bets on President Prabowo’s resignation spread on local social media. The pattern is consistent. The governments classify event-contract betting as gambling, then act when politically sensitive markets emerge on the platforms.
The global regulatory environment for prediction markets is tightening simultaneously across multiple jurisdictions. Just as the industry reaches multibillion-dollar scale.
The Broader Stakes for Prediction Markets
The Kalshi vs Polymarket competitive dynamic plays out differently across jurisdictions. Kalshi operates under CFTC regulation in the United States, a licensed, compliant framework. Polymarket is blockchain-based and decentralized. In Spain, that distinction is irrelevant. Neither holds a Spanish gambling license, so both face identical treatment
Crypto regulation news from Europe increasingly reflects this pattern. Technical architecture does not override local gambling classification. A decentralized prediction market without local licensing faces the same blocking order as a traditional betting platform. For Spanish users, VPN adoption will almost certainly follow, the same response seen in Indonesia and Brazil. The block restricts access, but it does not eliminate demand from users who understand how to circumvent geographic restrictions.
スペイン、ギャンブルライセンス未取得のためPolymarketとKalshiをブロック
スペインは予測市場に門戸を閉ざす最新の国となった。消費者庁は火曜日にスペインの官報にポリマーケットとカルシーの制裁手続きを掲載した。両プラットフォームを無許可のギャンブル運営者として分類している。庁は同時にインターネットサービスプロバイダーに対し、両ウェブサイトへのアクセスを全国的にブロックするよう命じた。
ブロックは運営者に応じて7日から10日以内に実施される予定だ。制裁手続き自体は最終決定までに3〜4ヶ月かかる見込みだ。ポリマーケットのニュースは、スペインを予測市場をギャンブルとみなす国の増加リストに加える。ブロックチェーンベースや規制準拠の構造に関わらず。

今後何が起こるか
3〜4ヶ月の制裁プロセスが最終的な罰則を決定する。両プラットフォームは手続きに異議を唱えることができるが、庁が既知の海外住所に対して直接通知を試みたものはすでに失敗している。これはプラットフォーム側の協力が限定的であることを示唆している。
予測市場業界全体にとって、世界的な取り締まりの加速は構造的な疑問を投げかける。真の予測機能を提供し、政治的結果に関して従来の世論調査よりも明らかに正確であるプラットフォームは生き残れるのか。規制環境がデフォルトでギャンブルとみなす中で、存続できるのか。答えはますます、予測市場と従来の賭けを区別する目的別の枠組みを主要な法域が構築するかどうかにかかっている。その枠組みは欧州にはまだ存在しない。存在するまでは、ブロックは続く。
