Cash-Only Betting: A Radical Proposal to Combat Gambling Addiction

The United States is currently witnessing an unprecedented gambling explosion that brings significant social costs. Since the 2018 Supreme Court ruling, more states have legalized sports betting, leading to skyrocketing revenues. However, as the industry and states profit, social issues like addiction and crime are mounting. A central problem often overlooked is the complete digitization of payments, which makes betting a frictionless, almost mindless act where players lose their sense of the value of money.

The proposal to force gamblers to use physical cash might seem regressive in a digital world, but it could serve as an effective barrier against financial ruin. In a casino, a dealer requires paper money before providing chips. This moment of handing over physical currency creates a psychological hurdle that is entirely absent when simply clicking an app on a smartphone. The goal is to introduce friction into a process designed for maximum speed and minimum resistance to maximize industry profits.

Numbers and facts

The economic scale of the US market is massive. In 2025, American casinos and sportsbooks earned a total of $79 billion. This represents a nearly 20% increase from the $66.5 billion earned just two years prior. These figures highlight the rapid expansion of the market. Meanwhile, World Health Organization (WHO) estimates suggest about 1.2% of the global population has a gambling problem. In the US, recent estimates place this number at 20 million people, or about 6% of the population.

Negative consequences are also evident in major criminal cases. For instance, the chief of police in New Haven, Connecticut, allegedly embezzled nearly $4.5 million in government funds for sports betting. Professional sports also face scandals, with basketball stars accused of betting on their own games. Even prediction markets show abuse; on April 23, 2026, a Special Forces soldier was arrested for winning over $400,000 using classified information about Venezuelan leader Nicolás Maduro.

Background

The roots of the current boom lie in legal liberalization. Platforms like Kalshi and Polymarket utilize loopholes by offering prediction markets regulated at the federal level by the Commodity Futures Trading Commission. This allows them to bypass stricter state rules, such as those in Montana or Nebraska, where some betting must be done in person. While industry proponents point to job creation, employment numbers are stagnant. In 2024, there were about 67,000 workers in the sector, still below the 2007 peak of nearly 70,000.

The proposal suggests that accounts should only be funded with cash at kiosks or stores. This would not only complicate things for anonymous big bettors, known as "whales," but also prevent impulsive players from draining their bank accounts with a single click. Furthermore, any cash transaction over $10,000 in the U.S. requires a Currency Transaction Report, adding an extra layer of transparency.

Why it matters for German players

In Germany, the Interstate Treaty on Gambling 2021 (GlüStV 2021) is the standard. While the US debates cash mandates, Germany already utilizes technical hurdles. The central LUGAS system monitors the monthly deposit limit of 1,000 euros across all providers. Nevertheless, digital payments remain a double-edged sword here too. The convenience of e-wallets and instant transfers can lead to reaching the 1 euro per spin limit on virtual slots faster than one's wallet can handle. German players should ensure they only play at providers on the GGL whitelist to benefit from strict protection measures.

What it means for GGL-licensed casinos

For operators with a license from the Gemeinsame Glücksspielbehörde der Länder (GGL), focusing on player protection is a constant balancing act. The call for more physical interaction in payments could become relevant in Europe if addiction rates rise despite systems like LUGAS and OASIS. Currently, cash is not a standard feature for online casinos in Germany, but the integration of retail-purchased prepaid systems provides a bridge. GGL-licensed casinos must ensure their payment methods are not only secure but transparent to meet regulatory anti-money laundering and player protection standards.
