The landscape of prediction markets has expanded dramatically, encompassing a wide array of real-world events. These markets, where individuals can bet on the outcomes of various events, have grown into a $40 billion industry attracting millions of dollars in bets on everything from political events to natural disasters.
However, this growth has sparked debates about the ethical implications and potential abuses of such platforms. As prediction markets continue to evolve, experts are calling for a closer look at the perverse incentives and moral hazards they may create.
The Rise of Prediction Markets in Reality TV
One of the most surprising areas where prediction markets have taken hold is in reality TV. Platforms like Kalshi and Polymarket allow users to bet on the outcomes of popular shows such as Big BrotherThe Bachelor and Survivor. These bets are not just a form of entertainment; they have become shockingly accurate, with some predictions reaching 90% accuracy or higher.
The accuracy of these predictions can be attributed to the flow of insider information. Reality TV shows are typically filmed months before they air, and production teams, cast members, and their acquaintances often have knowledge of the outcomes. This information can trickle out, allowing savvy bettors to place informed wagers. Despite strict non-disclosure agreements (NDAs), the gray areas in these contracts make it possible for insider information to influence the markets.
The Impact on Viewers and Fans
For dedicated fans of reality TV, the rise of prediction markets has had a significant impact. The fear of spoilers has led many viewers to avoid social media, message boards, and even discussions with friends. Some fans have turned to less popular shows, like Peacock’s The Five Star Weekend to avoid the spoiler culture that has become prevalent in the betting community.
To protect their viewing experience, fans have adopted strategies such as avoiding live shows with quick turnaround times, like Big Brother or Love Island and instead focusing on shows that are less prone to spoilers. However, the cultural shift brought about by prediction markets has made it increasingly difficult to enjoy reality TV without encountering spoilers.
The Ethical Dilemmas of Betting on Real-World Events
The ethical concerns surrounding prediction markets extend far beyond reality TV. Betting on geopolitical events, natural disasters, and even the deaths of public figures raises serious questions about the normalization of such activities. Experts argue that these markets can create perverse incentives where individuals may be motivated to influence the outcomes of events for personal gain.
For example, in 2026, users on Polymarket spent over $1 million betting on scenarios linked to the Palisades wildfires. Similarly, bets were placed on the likelihood of war with Iran and the capture of Venezuela’s leader, Nicolás Maduro. While platforms like Kalshi claim to avoid listing contracts tied to violent events, the line between permissible and impermissible bets is often blurred.
The Wisdom of the Crowd and Its Limitations
Proponents of prediction markets argue that they reflect the wisdom of the crowd aggregating thousands of individual judgments into forecasts of specific events. Traders on platforms like Kalshi and Polymarket are offered binary contracts, such as whether the U.S. Federal Reserve will raise interest rates by 25 basis points. These contracts are traded like financial assets, with prices rising or falling based on traders’ beliefs in the outcome.
However, the wisdom of the crowd argument begins to unravel when considering the structure of these markets. Traders can see market prices and betting activity in real time, which can lead them to abandon their own assessments in favor of following the crowd. Additionally, the market prices may be influenced more by a few wealthy traders than by the collective wisdom of the masses.
The Legal and Ethical Landscape
The legal landscape surrounding prediction markets is complex and evolving. While platforms like Polymarket are federally regulated and have rules against insider trading, fraud, and market manipulation, the ethical implications of these markets remain a concern. California, in particular, has a history of grappling with the rapid growth of technology platforms and their impact on public life.
California Attorney General Rob Bonta has led lawsuits against social media companies for their addictive features, highlighting the need for regulations that protect civic integrity. As prediction markets become more mainstream, there is a growing call for state lawmakers and consumer protection officials to set expectations for these platforms, ensuring they do not become tradable entertainment at the expense of real-world consequences.
The ethical dilemmas posed by prediction markets are not merely hypothetical. In 2026, U.S. prosecutors charged a Google software engineer with using confidential internal data to earn roughly $1.2 million trading on Polymarket. This case underscores the potential for insider trading and market manipulation in these platforms, raising questions about their long-term viability and ethical implications.
