David Schwartz Explains Why Stock Markets and Prediction Markets Are Not Casinos

Former Ripple CTO David Schwartz has pushed back against the growing argument that stock markets and prediction markets are no different from casinos. In a discussion on X on June 17, 2026, Schwartz challenged users who claimed that trading is simply a more sophisticated term for gambling.

Schwartz, who stepped down from Ripple’s day-to-day operations at the end of 2025 and now serves as CTO Emeritus, argued that the comparison overlooks a key economic distinction. According to him, gambling and investing serve fundamentally different purposes within the financial system.

The debate started when several X users suggested that stock trading and prediction market participation are essentially forms of betting. Schwartz rejected that view, emphasizing that gambling primarily transfers existing wealth between participants, while investing helps create new value by directing capital into productive activities.

“A key way to see the difference is this: If you have positive expected value in gambling, something has gone very wrong. If you have negative expected value in investing, something has gone very wrong,” Schwartz stated.

His argument centers on expected value. In a casino, the house is designed to maintain an advantage, meaning players generally face negative expected returns over time. If a gambler consistently profits, it often indicates a flaw in the system. By contrast, financial markets are designed to generate value through economic growth, innovation, and business expansion. Investors who participate in productive markets can benefit from that value creation.

Schwartz’s comments carry additional significance due to his long-standing role in the cryptocurrency industry. As one of the architects of the XRP Ledger and a prominent voice within the XRP community, his opinions frequently influence discussions surrounding digital assets and market structure.

Earlier in 2026, Schwartz also attracted attention for challenging viral XRP price predictions. Using market capitalization analysis, he argued that many ambitious XRP forecasts would require valuations exceeding the total global money supply, making such projections unrealistic.

At the time of writing, XRP is trading at approximately $1.19, down 3.64% over the past 24 hours, with a market capitalization of around $74.2 billion. The cryptocurrency remains among the top digital assets by market value.

The discussion comes as prediction markets face increasing regulatory scrutiny across the United States. More than a dozen states have moved to classify event-contract platforms as forms of gambling, raising questions about how these markets should be regulated. Whether regulators adopt Schwartz’s value-creation perspective or continue to view prediction markets through a gambling framework could play a major role in shaping future policy decisions.
