Spain Blocks Prediction Markets Polymarket and Kalshi

Spain has opened sanction proceedings against prediction-market platforms Polymarket and Kalshi and ordered their websites blocked while regulators investigate whether they operated without required gambling authorization. The Spanish gambling regulator classifies prediction markets that let users wager on uncertain future events as gambling products, meaning a specific license is required. The access ban is described as a precautionary measure. Spanish authorities expect a decision in about three to four months. The regulator’s stated focus is consumer protection and access controls, including requirements around blocking minors and self-excluded users and adding supervision and harm-reduction rules. For crypto traders, the immediate impact is reduced access and potential liquidity for Polymarket and Kalshi users in Spain. More broadly, the case underscores country-by-country licensing risk for prediction markets, with likely tighter geo-blocking and stricter identity checks that could ripple across Europe and affect how traders participate in yes/no event contracts tied to politics, sports, crypto prices, and other global catalysts. Regulatory scrutiny is not limited to Europe: the broader reporting context highlights earlier actions in Asia and intensified U.S. debate around market integrity, user verification, and insider-risk controls. The key takeaway is that prediction markets remain exposed to licensing enforcement, which can quickly shift venue availability and trading flow.
