Spain Blocks Polymarket and Kalshi Over Missing Gambling Licenses

Regulatory Action

Spain's Directorate General for Gambling Regulation instructed internet service providers to block access to Polymarket and Kalshi after determining both platforms operated without required gambling licenses. The Ministry of Consumer Affairs initiated the review, according to the regulator's statement.

Market Context

Polymarket and Kalshi are among the largest prediction market platforms globally, allowing users to place bets on event outcomes ranging from elections to sports results. Polymarket operates on Ethereum and is accessible cross-border; Kalshi focuses on U.S.-based events. Neither platform had sought or obtained a gambling license from Spanish authorities prior to the blocking order.

Broader Implications

The action signals Spain's willingness to enforce existing gambling frameworks against decentralized and offshore platforms. Other European regulators, including those in France and Germany, have taken similar enforcement steps against unlicensed crypto-native betting venues in recent years, though few have moved as directly against specific platforms via ISP-level blocking.

Why It Matters

For Traders

Users in Spain no longer have direct ISP access to these platforms; traders may face higher latency or require VPN workarounds, though transactions remain possible on-chain.

For Investors

Prediction markets face regulatory pressure in major markets; licensing requirements could raise operational costs and fragment user bases across jurisdictions.

For Builders

Platforms targeting European users must now factor mandatory gambling licensing into product and legal roadmaps or accept regional blocking.
