Spain\u2019s Ministry of Consumer Affairs opened disciplinary proceedings against prediction market platforms Polymarket and Kalshi and ordered internet service providers to block access to the platforms.<\/p>\n
In notices published in the country\u2019s official state gazette, Spain\u2019s gambling regulator, the Directorate General for Gambling Regulation (DGOJ), said the companies were offering betting products tied to uncertain future events without the licenses required under Spanish law, according to local news outlets<\/a>.<\/p>\n Authorities said the precautionary blocking measures would remain in place while the cases proceed, a process expected to take three to four months.<\/p>\n The notices came after regulators failed to notify the companies through known foreign addresses.<\/p>\n Kalshi and Polymarket currently dominate prediction markets\u2019 trading activity. Over the past 30 days, Kalshi recorded roughly $5.9 billion in trading volume while Polymarket processed about $3.8 billion, according to DeFiLlama data<\/a>.<\/p>\n Combined, the two platforms represent nearly 88% of the roughly $11 billion in trading volume among the sector\u2019s top markets during the period.<\/p>\n The move sees Spain join a growing number of jurisdictions targeting prediction markets as regulators debate whether the products should fall under gambling or financial market rules.<\/p>\n Indonesia blocked Polymarket earlier this week<\/a> under online gambling restrictions, as did India<\/a>. Other countries including Taiwan, Thailand China, and Japan have restricted the platform, while Ukraine blocked it with no legal way for it to come back.<\/a><\/p>\n Polymarket\u2019s list of blocked countries also includes Belgium, Australia, France, the U.K., and Germany. The platform is relaunching in the U.S.<\/a><\/p>\n
