TL;DR
Spain has prohibited Polymarket and Kalshi from operating within its jurisdiction, citing absence of required gambling licenses. This move underscores regulatory scrutiny over prediction markets linked to cryptocurrencies. The platforms are now unable to offer services in Spain, with future legal steps uncertain.
Spain has blocked the operation of prediction markets Polymarket and Kalshi over their failure to obtain necessary gambling licenses, marking a significant regulatory development for crypto-based prediction platforms in the country.
The Spanish authorities announced the ban on May 26, 2026, citing that both Polymarket and Kalshi do not hold the required gambling licenses to operate legally within Spain. The move follows ongoing regulatory scrutiny of online prediction markets, especially those connected to cryptocurrencies.
According to Spain’s Directorate General for the Regulation of Gambling, the platforms are classified as gambling operators under national law, and thus must obtain official licenses to offer their services. The platforms have not secured such licenses, leading to their prohibition from serving Spanish users.
Both Polymarket and Kalshi have confirmed that they are no longer accessible to users in Spain. The companies have yet to comment publicly on potential legal appeals or future compliance steps.
Why It Matters
This development signals increased regulatory pressure on crypto-linked prediction markets across Europe, emphasizing national authorities’ focus on gambling and financial regulation. It may impact the global operations of similar platforms and influence the broader debate over how prediction markets should be regulated.
For users, this means reduced access to these platforms within Spain, raising questions about the future of such markets in other jurisdictions with similar regulatory frameworks. The move also highlights ongoing legal uncertainties surrounding the classification and regulation of crypto-based betting and prediction services.
