Can You Sue Predictive Markets for Being Addictive by Design?

Key Takeaways 

• Prediction markets allow users to buy and sell contracts based on future events and can function similarly to gambling when money is tied to uncertain outcomes. 
• The global prediction market industry was valued at over $10 billion in 2023 and continues to grow. 
• Platforms like Kalshi are regulated as financial exchanges, but critics argue the psychological mechanics mirror sports betting. 
• Younger users may be especially vulnerable due to impulse control development and digital platform design. 
• Legal liability could emerge if platforms are shown to encourage addictive behavior while knowing the risks. 

Prediction markets present themselves as financial tools. But when money is tied to uncertainty and reward, the legal and psychological questions begin. 

As predictive trading platforms grow in popularity, especially among younger Americans, a new issue is surfacing: 

If these platforms are designed to trigger addictive behavior, can they be sued? 

The answer depends on how courts ultimately classify them: as financial exchanges, as gambling products, or something in between. 

What Are Prediction Markets and How Do They Work? 

Prediction markets allow users to buy and sell contracts based on the likelihood of future events. 

Users might trade on: 

• Election outcomes 
• Sports results 
• Economic data releases 
• Regulatory decisions 
• Cultural events 

A contract increases in value if the predicted event becomes more likely and pays out if correct. 

Alex Boris, Senior Trial Attorney at J&Y Law who was recently named a Top Family Lawyer by the Daily Journal for his work protecting children against negligent schools and corporations, previously worked in Washington, D.C. for the American Gambling Association (AGA). There he conducted research on problem gambling as part of the casino industry’s internal harm-reduction and risk-analysis efforts. He explains predictive markets this way: 

“It’s essentially wagering with a different label. You’re putting money behind a prediction and collecting if it goes your way. Dressing it up in financial terminology doesn’t change the mechanics.” 

Prediction markets are not new. Early academic versions gained attention in the 2000s. Today, companies like Kalshi operate federally regulated event contract exchanges under oversight from the Commodity Futures Trading Commission. 

The global prediction market industry was valued at approximately $10.3 billion in 2023 and is projected to grow significantly over the next decade. Some platforms process millions of contracts during major political cycles or sporting events. 

Where Does the Gambling Element Come Into the Picture? 

The line between investing and gambling often comes down to uncertainty tied to financial reward. 

“When you attach money to uncertainty and offer a payout, you activate the same psychological triggers you see in traditional gambling,” Boris says. “Rebranding it as a market doesn’t change the behavioral impact.” 

Behavioral psychology research consistently shows that variable reward systems reinforce repetitive behavior. That principle is well documented in gambling studies and digital platform design research. 

The legal question is whether prediction markets cross from financial participation into gambling-like risk exposure, especially when design choices encourage continuous engagement. 

Why Are Younger Americans Drawn to Prediction Markets? 

Younger users often view prediction markets as analytical or strategy-driven rather than purely speculative. 

They may see them as skill-based. They may view participation as following politics, sports, or economics more closely. But that framing can blur the underlying risk. 

According to the National Council on Problem Gambling, approximately 2.5 million U.S. adults meet criteria for severe gambling problems, and another 5–8 million experience mild or moderate gambling-related harm. Younger adults consistently show higher rates of risky gambling behavior than older groups. 

When platforms are structured to resemble financial trading rather than betting, some users may underestimate the behavioral impact. 

What Are the Primary Risks for Younger Users? 

Critics argue that the core issue is not the event contracts themselves, but how they are structured. 

“The design is what concerns me most,” Boris explains. “Continuous markets and instant outcomes can reinforce compulsive behavior. Younger users are still developing financial judgment and impulse control, which makes that loop more dangerous.” 

Over time, repeated exposure to loss and reward cycles can lead to: 

• Escalating financial losses 
• Anxiety and secrecy 
• Distorted perceptions of probability 
• Debt accumulation 
• Risk normalization 

Courts evaluating these cases will likely look beyond labels and examine design features, user demographics, and internal knowledge of behavioral risks. 

What Are Regulators and Companies Doing? 

Platforms operating in the United States argue that they comply with existing financial regulations. 

Some have implemented: 

• Age verification systems 
• AI-based monitoring for suspicious activity 
• Spending disclosures 
• Educational risk warnings 

But regulatory classification does not automatically resolve product design questions. As seen in litigation involving social media platforms and gaming companies, courts increasingly examine whether companies foresaw harm and whether safer alternatives were available. 

Can You Sue Predictive Markets for Being Addictive by Design? 

Legal theories would likely include: 

• Negligent design 
• Failure to warn 
• Unfair or deceptive business practices 
• Targeting vulnerable populations 
• Consumer protection violations 

To succeed, a plaintiff would generally need to show: 

1. The platform knew or should have known its design created foreseeable harm 
2. Safeguards were inadequate 
3. Measurable damages occurred 
4. The harm was linked to platform structure or practices 

This is not new territory. Lawsuits against social media companies and gaming platforms have advanced similar arguments about addictive design and youth targeting. 

If internal documents were to show that younger users were disproportionately driving engagement, that behavioral risks were understood, and that design changes were considered but rejected, those facts could become central in litigation. 

The key issues will be foreseeability and intent. 

Where Liability Questions Begin 

The larger issue may not be whether prediction markets are legal. It may be whether they are responsibly designed. 

If evidence shows that companies understood the psychological impact of their design, recognized youth vulnerability, and prioritized growth over safeguards, courts may treat these cases less like financial disputes and more like product liability claims involving digital damages. 

As predictive markets expand and transaction volume grows, legal scrutiny is likely to follow. 

Working with J&Y Law on Prediction Market Digital Damages Cases 

Prediction markets sit at the intersection of finance, technology, behavioral psychology, and consumer protection. 

Some view them as innovation. Others see gambling repackaged in market language. 

If you or someone you love has suffered financial harm tied to compulsive use of predictive trading platforms, legal options may exist depending on the facts.
