The Ban Trap: How Prediction Market Restrictions Fuel Public Interest

The global gambling landscape is facing a significant paradox as regulatory attempts to curb prediction markets appear to be fueling their growth. A comprehensive study by CasinoReviews.net indicates that bans on platforms such as Polymarket and Kalshi often correlate with higher public search interest rather than a decline in activity. Analyzing primary Google Trends data from September 2025 to September 2026 across 51 countries, the report suggests that the current regulatory approach might be inadvertently boosting the platforms' profiles.

The research finds that global attention is driven primarily by high-stakes political events rather than the legal battles that dominate industry headlines. Prediction markets, which allow users to trade on the outcome of future events, have become a focal point for bettors during times of political uncertainty. Even in jurisdictions where these services are strictly prohibited, the public continues to seek them out, often bypassing local restrictions with ease. This highlights a significant challenge for authorities attempting to enforce national gambling laws in a borderless digital environment.

Numbers and facts

The data provides a startling look at user behavior in restricted markets. Eight of the top 15 countries for Polymarket search share are jurisdictions that currently restrict or have formally banned prediction markets. For Kalshi, four of the top 15 countries fall into this category. The single highest point in worldwide search interest for Polymarket during the study period occurred on June 7, 2026, coinciding with Peru's presidential runoff. Another major surge was recorded on April 12, 2026, during the Hungarian parliamentary elections and Peru's initial voting round.

While Kalshi reportedly trades more money than Polymarket, it attracts significantly less search attention outside the United States. In its home market, Kalshi leads with a 21% share compared to Polymarket's 19%. However, Kalshi's presence drops to single digits in almost every other country studied. Conversely, Polymarket has established a broader global footprint. In China, despite being blocked by the Great Firewall, Polymarket is actively hiring Mandarin-speaking staff and building markets for the Lunar New Year. The report suggests that hundreds of millions of dollars in contracts are routed through China every month via VPN workarounds.

Background

The legal classification of these platforms remains a point of contention. Companies like Kalshi view themselves as financial exchanges offering derivative contracts, while regulators and competitors often see them as unlicensed gambling operators. In the U.S., Representatives Steven Horsford and Mark Amodei introduced the Prediction Markets Are Gambling Act to close federal loopholes. On August 29, 2026, a federal appeals court panel in the Ninth Circuit ruled that certain sports contracts on Kalshi constitute gambling, preventing the platform from restarting those trades in Nevada. This decision contradicts an earlier ruling from a different circuit in New Jersey, potentially setting the stage for a Supreme Court showdown.

"Looking at the last 12 months of prediction markets, and the sheer media noise generated around them, it’s clear that trying to combat their rise has seen a similar spike in publicity. Rather than bans quietening the noise around the platforms, we’re seeing the opposite occur, highlighting that the current approach isn’t working for regulators." - Nikoleta Kuncheva, Lead Researcher at CasinoReviews.net

Why it matters for German players

For players in Germany, the rise of these markets presents a legal grey area with significant risks. Under the State Treaty on Gambling 2021 (GlüStV 2021), only operators licensed by the GGL are permitted to offer online betting services. Prediction markets do not hold such licenses and their offerings, particularly political betting, are not currently sanctioned under German law. Consequently, participation from Germany is considered illegal gambling, leaving consumers without the protections mandated by German law.

Licensed German operators are required to implement strict safety measures, including a 1,000 Euro monthly deposit limit and integration with the LUGAS and OASIS systems. Prediction markets operate outside these frameworks. As the CasinoReviews report shows that users in countries like Hungary and China frequently use VPNs to access blocked sites, it is likely that German residents are doing the same. However, doing so means forfeiting any legal recourse for unpaid winnings and risking the loss of funds if the platform identifies the use of prohibited access tools.

What it means for GGL-licensed casinos

For GGL-licensed casinos and sportsbooks, these platforms represent a form of unregulated competition that does not play by the same rules. While legitimate businesses invest heavily in compliance and player protection, prediction markets capitalize on the excitement of global events without the overhead of local regulation. The massive interest during elections suggests a market demand that is currently unserved by the legal German market. The GGL faces the difficult task of addressing this shadow market, which, according to the latest data, seems to thrive on the very controversy that regulators create through bans.
