Dangerous Wagers on Kalshi: Prediction Markets Lure Recovering Addicts into Traps

The world of online betting is changing rapidly, but for people like Thomas from Pennsylvania, this shift is a nightmare. After declaring bankruptcy due to a severe gambling addiction and $75,000 in debt, his life seemed back on track. He used self-exclusion programs at major sportsbooks and swore off gambling. Then, an ad for Kalshi appeared in his Instagram feed. What was marketed as harmless event trading turned out to be a dangerous loophole that cost him another $25,000.

Thomas is not an isolated case. Experts are sounding the alarm as platforms like Kalshi and Polymarket launch aggressive campaigns, often targeting regions where traditional sports betting is illegal or strictly regulated. While traditional bookmakers in the U.S. are monitored by states and must respect exclusion lists, prediction markets operate in a legal gray area. They are often declared as event stock exchanges, meaning the strict protections for problem gamblers do not apply. The consequences are devastating: individuals who took courageous steps toward self-exclusion suddenly find themselves on an app with no obstacles to excessive gambling.

Numbers and facts

The industry's growth figures are staggering. In the last month, bettors on Kalshi traded nearly $60 billion. Compared to the same month last year, when volume was at $2.8 billion, this represents an increase of more than 2,000 percent. Kalshi benefits from being classified as a provider of swaps, a type of financial instrument supervised by federal officials rather than state gambling authorities. This legal framework is currently being challenged in court and could reach the Supreme Court.

The company invests heavily in marketing. In May alone, Kalshi donated $2 million to the National Council on Problem Gambling after years of insisting it does not offer gambling. However, the firm refuses to participate in state-maintained self-exclusion databases. In Pennsylvania, over 30,000 residents are registered in such programs, yet Kalshi remains accessible to them. The platform also uses celebrities like Timothée Chalamet and Lionel Messi to sharpen its profile and present betting as a modern lifestyle choice.

Background

Critics like Brian Pempus, a former sports betting journalist and current responsible gambling advocate, see these platforms as a deliberate deception. They are gamified and designed to maximize screen time and user stakes. Particularly problematic are markets that restart every 15 minutes, such as those on the price of Bitcoin. Such offers generate quick dopamine hits comparable to the addictive nature of slot machines.

"I have a gambling addiction and have been self-excluded from regulated gambling platforms for years. I want to close my account permanently." - Thomas, affected individual from Pennsylvania, in a chat log with Kalshi

The company's response to such pleas is often deemed inadequate. While Thomas repeatedly asked for a permanent ban, automated systems merely suggested "trading breaks" or "individual funding caps." It took days and several emails before his account was actually closed. By that time, the financial damage was already immense.

Why it matters for German players

In Germany, the situation is much more strictly regulated by the State Treaty on Gambling 2021 (GlüStV 2021). Anyone who excludes themselves via the cross-provider OASIS system is blocked from all legal offerings. This includes both online casinos and sports betting providers with a license from the Joint Gambling Authority of the States (GGL). Strict rules, such as the cross-provider deposit limit of 1,000 euros per month and the 1 euro per spin limit on virtual slots, serve to protect against the kind of crashes Thomas experienced.

However, access to international platforms or so-called prediction markets that do not hold a German license remains problematic. These providers are not subject to the LUGAS monitoring system and often offer no connection to OASIS. German players should therefore be extremely cautious: if a platform is not on the GGL's official white list, all legally guaranteed protection mechanisms are missing. Self-exclusion on such a site is often difficult to enforce and offers no protection against aggressive marketing emails or bonuses that encourage further play.

What it means for GGL-licensed casinos

For operators with a GGL license, the Kalshi case highlights the importance of their regulatory duties. German providers must ensure that marketing measures are not misleading and do not target vulnerable individuals. The integration of LUGAS and OASIS is not a bureaucratic hurdle but the central safety net for the market. While U.S. platforms face criticism for aggressive bonus offers like $20 for a $10 bet, German providers must follow stricter advertising rules to fulfill the channeling mandate without creating addictive incentives.
