Spain's telecommunications regulator has blocked access to Polymarket and Kalshi, two major prediction market platforms, citing unlicensed gambling operations. The move marks the latest regulatory crackdown on decentralized betting platforms operating without proper licensing in European markets.
Spanish authorities classified both platforms as illegal gambling services operating without required permits. Users attempting to access Polymarket and Kalshi within Spain now encounter network blocks. The regulator did not specify whether the blocks applied to VPN circumvention or other technical workarounds.
Polymarket operates as a decentralized prediction market built on Ethereum, allowing users to trade contracts on real-world event outcomes. The platform recorded explosive growth following the 2024 U.S. presidential election, briefly becoming the largest prediction market globally. Kalshi functions similarly, offering event-based derivatives trading on regulated U.S. exchanges, though it also faces international market restrictions.
The Spanish action reflects broader European regulatory resistance to prediction markets operating outside traditional gambling frameworks. Several EU nations previously restricted or investigated similar platforms over consumer protection and gambling licensing requirements. Spain's move demonstrates regulators view prediction markets as betting services requiring domestic licenses and oversight, rather than pure financial instruments or decentralized protocols exempt from gambling rules.
Polymarket and Kalshi operate with varying regulatory approaches across jurisdictions. Kalshi maintains U.S. regulatory approval through the Commodity Futures Trading Commission and operates with specific market restrictions. Polymarket takes a more decentralized approach, allowing global participation but increasingly facing geographic restrictions as regulators tighten enforcement.
The Spanish blocks signal prediction market operators face mounting pressure to either obtain local licenses or accept geographic limitations. France, Germany, and other European regulators have similarly targeted these platforms. This pattern suggests prediction markets may fragment into licensed regional markets or retreat from heavily regulated jurisdictions entirely. For users and platforms, Spain's action reinforces that operating as dec
