Prediction Markets Meet Regulators: What Spain's Block of Polymarket and Kalshi Reveals

Spain's gambling regulator has ordered ISPs to block access to Polymarket and Kalshi — two of the most prominent prediction market platforms in the world — citing the absence of valid gambling licences. The decision is not just a footnote in fintech news. It is a signal that regulators across the globe are catching up with a category of product that has, until recently, operated in a comfortable grey zone.

What Are Prediction Markets, and Why Do Regulators Care?

Prediction markets let users buy and sell contracts whose value is tied to the outcome of real-world events — elections, economic indicators, sports results, or anything else that resolves to a binary yes/no. The price of a contract at any moment functions as a crowd-sourced probability estimate.

From a pure information-theory standpoint, these platforms are genuinely useful. Research consistently shows that well-functioning prediction markets outperform polls and expert panels at forecasting outcomes. But from a regulatory standpoint, the mechanics look almost identical to sports betting: money changes hands based on uncertain future events. That equivalence is hard to argue away in front of a licensing board.

Spain's General Directorate for the Regulation of Gambling (DGOJ) drew exactly that conclusion. Without a licence, the platforms are, by Spanish law, operating illegal gambling services — full stop.

The "Information Tool vs. Gambling Platform" Distinction Is Collapsing

Polymarket and Kalshi have both, at different times, argued that their platforms are forecasting tools rather than gambling venues. Kalshi fought a multi-year legal battle with the CFTC in the United States to be classified as a derivatives exchange rather than a gambling operator — and largely won that framing domestically.

But that US regulatory carve-out does not travel well. The EU's member states retain significant autonomy over gambling law, and Spain's regulators are not obligated to accept the CFTC's framing. What this creates is a patchwork compliance problem:

A product can be legal in one jurisdiction under one regulatory label.
The exact same product can be illegal in another jurisdiction under a completely different label.
The underlying technology is identical in both cases.

This is the classic challenge of building a globally-distributed platform in a domain that touches money, outcomes, and public interest events.

Three Lessons for SaaS Founders and Platform Builders

1. Regulatory classification is a product decision, not just a legal one

How you describe your product — its framing, its UI, its terminology — feeds directly into how regulators will classify it. "Forecasting market" and "betting platform" can describe the same smart contract. The words you choose in your onboarding flow, your terms of service, and your press releases will be read by regulators. Design for that audience early, not after a cease-and-desist letter.

2. Geo-blocking is not a compliance strategy — it is a band-aid

Many platforms respond to regulatory pressure by simply blocking IP addresses from jurisdictions where they have not received approval. This delays the problem without solving it. VPN usage is trivial. More importantly, operating without a licence and relying on geoblocking to avoid enforcement is an increasingly untenable posture as regulators grow more technically sophisticated.

A more durable approach: build compliance as a configurable layer in your architecture. Structure your backend so that feature flags, payment flows, and contract types can be toggled per-jurisdiction without requiring a full redeploy.

# Example: jurisdiction-aware feature config
jurisdiction_rules:
  ES:
    prediction_markets_enabled: false
    requires_licence: ["DGOJ"]
  US:
    prediction_markets_enabled: true
    regulatory_framework: "CFTC_derivatives"
  GH:
    prediction_markets_enabled: true
    regulatory_framework: "NCA_pending_review"

3. First-mover advantage has a regulatory ceiling

Polymarket and Kalshi moved fast, captured liquidity, and built recognisable brands. But speed of adoption does not confer regulatory legitimacy. The platforms that will dominate the next decade of fintech are those that treat regulatory compliance as a distribution channel — because a licence in a major market is, effectively, a barrier to entry that protects incumbents who do the hard work of obtaining it.

What This Means for Emerging Markets

For builders in markets like Ghana, Nigeria, or Kenya — where fintech regulation is still maturing — the Spain situation is instructive in both directions. On one hand, lighter-touch regulation in early-stage markets provides room to experiment and ship. On the other hand, that window closes. Regulatory frameworks in Africa are moving faster than most founders expect, particularly in the payments and digital assets space.

Building with compliance in mind from day one is not a constraint on innovation. It is, increasingly, the innovation. The teams that figure out how to make compliant infrastructure elegant and developer-friendly will build the platforms that last.

The Broader Trajectory

Spain's block is unlikely to be the last of its kind. France, Germany, and several other EU member states are actively reviewing how prediction markets fit into their existing gambling and financial services frameworks. The UK's Gambling Commission has already signalled interest. This is a category-wide regulatory reckoning, not an isolated national quirk.

For the platforms themselves, the path forward involves either pursuing licences market by market — expensive, slow, but durable — or retreating to jurisdictions where they have regulatory cover and accepting a smaller addressable market.

Neither option is painless. Both require treating legal infrastructure with the same seriousness as technical infrastructure.

Why this matters for your project: If you are building any platform where users transact around uncertain outcomes — prediction tools, wagering features, incentive markets, or even certain DeFi integrations — the classification of your product under local law is a technical architecture decision as much as a legal one. At Code!nk Technologies, we help teams design compliance-aware systems that can scale across jurisdictions without requiring a full rebuild every time a regulator redraws the lines.
