Spain's gambling regulator has taken a significant step by ordering internet service providers to block access to prediction markets like Polymarket and Kalshi. This action reflects an ongoing trend in various countries where regulatory bodies view these markets as unlicensed gambling rather than as innovations in financial trading.
The Dirección General de Ordenación del Juego, Spain's gambling authority, issued these directives on May 26, mandating ISPs to restrict access to both platforms for a span of three to four months while they conduct investigations. The DGOJ cited concerns regarding the absence of proper licensing, inadequate identity checks, and lack of protections for minors as the primary reasons for their decision.
#Why is Spain Blocking Access to Prediction Markets?
The recent move by Spain is not isolated. It adds to a growing list of jurisdictions that perceive prediction markets as akin to betting operations rather than legitimate financial instruments. Notably, France was the first European nation to impose restrictions in late 2024, followed closely by Portugal and Hungary in early 2026. Countries like India and Indonesia have also taken similar actions.
As of March 2026, Polymarket has reported over 30 countries where its access is restricted or outright blocked. The implications of Spain's decision are significant, especially given that Polymarket and Kalshi have handled a staggering $9.7 billion in trading volume over the last month. Kalshi alone contributed approximately $5.9 billion while Polymarket accounted for around $3.8 billion, representing nearly 88% of the prediction market activity.
#How Does This Affect Investors?
At present, the impact of Spain's actions appears to be limited, as the nation does not constitute the largest market for either platform. Users keen on accessing these markets may utilize VPNs to navigate around ISP restrictions. Furthermore, the three to four-month timeframe for the investigation suggests that there may be room for negotiation should the platforms engage with Spanish authorities.
Nonetheless, this scenario presents a considerable risk for the prediction market sector. With Polymarket and Kalshi controlling such a large portion of the market volume, any regulatory difficulties they face can ripple through the entire ecosystem, affecting liquidity and potentially skewing the market odds that these platforms are designed to provide. Overall, investors should be mindful of the shifting regulatory landscape and its implications for market accuracy and trading volumes.
