How Prediction Markets Are Turning News Into Gambling—and Why It Must Stop

The integration of prediction markets into news reporting is creating a systemic risk to the integrity of journalism and the public’s engagement with current events. The Media and Democracy Project, known as MAD, has characterized this trend as casino journalism, arguing that the practice transforms substantive reporting into a gamified experience that prioritizes betting odds over the actual stakes of political and international developments.

This shift is driven by the explosion in popularity of prediction market platforms such as Kalshi and Polymarket. While these platforms present themselves as tools for distilling information and surfacing truth, critics argue they incentivize the financialization of real-world crises and create dangerous incentives for those producing the news that drives these markets.

Insider Trading and Market Manipulation

The potential for prediction markets to facilitate the monetization of classified information has already manifested in high-profile legal cases. On April 23, 2026, a U.S. Army Special Forces soldier was arrested on charges that he used classified information regarding a raid to capture Nicolás Maduro in Venezuela to win more than $400,000 by betting on the operation before it occurred.

Similar patterns of suspicious activity appeared prior to U.S. Military actions against Iran. According to reporting from the New York Times, hundreds of anonymous bets exceeding $1,000 were placed on the U.S. Striking Iran just hours before the attack took place, suggesting that some participants may have had advance knowledge of the strike.

Beyond the use of classified data, the financial scale of these markets creates a corrupting influence on journalists. An Israeli journalist recently received death threats after refusing to rewrite a report concerning an Iranian missile strike. The threats were linked to the fact that $23 million in prediction market investments were tied to the specific wording and framing of the news coverage.

The Rise of Media Partnerships

Major news organizations have begun formalizing relationships with these platforms, further embedding betting data into the news cycle. Dow Jones, the publisher of the Wall Street Journal, announced a partnership with Polymarket earlier in 2026. Other organizations, including CNN, the Associated Press, CNBC, and Substack, have entered into similar deals, though the specific terms of these agreements have not been disclosed.

The impact of these partnerships is evident in the way news is presented to the public. On March 30, 2026, the Wall Street Journal published a report stating that Polymarket Bets See Over 70% Chance of U.S. Forces Entering Iran in Next Month. MAD argues that such reporting lacks journalistic insight and functions more as an advertisement for the platform, providing betting odds and a link to Polymarket rather than substantive analysis.

Prediction markets turn events that have an impact on people’s lives — and carry a real human cost — into pure entertainment.

The Conflict Between Engagement and Journalism

The leadership of prediction markets defends the model as a superior method of forecasting. Tarek Mansour, the CEO of Kalshi, stated in a February 2026 interview with the Financial Times that prediction markets do not profit from losses, but rather from somebody’s engagement. Mansour has claimed that the platforms do a very, very good job at distilling information and surfacing truth to people, even as the company seeks to financialize everything.

However, journalism professors and media advocates argue that this form of engagement is detrimental. Jay Rosen, a journalism professor at New York University, has urged news organizations to focus not the odds, but the stakes. The concern is that focusing on the probability of an event crowds out coverage of the event’s substance, leaving voters and citizens with less information to evaluate the actual impact of government policies.

critics point to the addictive nature of gambling, noting that as sports betting has become more common, participants generally lose money over time. Integrating these mechanics into the news risks damaging reader trust and harming the overall well-being of the audience by promoting addictive behaviors under the guise of financial analysis.

Proposed Ethical Standards

To combat the rise of casino journalism, media advocates are calling for strict institutional policies. The New York Times is cited as a potential model for maintaining integrity, as its Guidelines on Integrity state that the organization must do nothing that would undermine or dilute its authority and reputation.

MAD has proposed several specific constraints for news organizations to protect their credibility:

• News outlets should publicly disclose the full terms of any financial relationships with prediction market platforms.
• Reporters should be forbidden from citing betting markets as valid forecasts.
• Journalists should be barred from using prediction market platforms themselves to avoid conflicts of interest.
• News organizations should forbid financial deals where the outlet profits from the success of a prediction market.

The goal of these measures is to shift the media’s focus away from speculation and back toward substantive reporting on the impacts of governmental actions. By distancing journalism from the mechanics of betting, advocates argue that the press can avoid the scandals associated with insider trading and the ethical pitfalls of gamifying human suffering.
