The world of prediction markets is under intense scrutiny as federal regulators investigate the controversial practice of mention betting. This form of wagering, where bettors place millions of dollars on the specific words spoken by public figures, has raised concerns about manipulation and deceptive marketing practices.
At the center of this controversy are two major prediction market platforms: Kalshi and Polymarket. These platforms have seen explosive growth, with sports wagers accounting for a significant portion of their trade volumes. However, the recent focus on mention markets has brought both platforms under the microscope.
CFTC’s Inquiry into Mention Markets
The Commodity Futures Trading Commission (CFTC) has launched an inquiry into mention markets, where bettors wager on the likelihood of specific words being uttered by public figures, ranging from politicians to sportscasters. This type of betting has become increasingly popular, but its susceptibility to manipulation has raised red flags among regulators.
In response to the CFTC’s inquiry, Kalshi has removed all mention markets related to sports from its betting offerings. This move is significant, as sports wagers account for more than 80% of the billions of dollars traded weekly on the site. Kalshi continues to allow wagers on political events, earnings calls, and live television newscasts, but the removal of sports-related mention markets is a clear indication of the regulatory pressure the company is facing.
The CFTC’s scrutiny comes in the wake of a high-profile incident involving President Trump‘s teleprompter operator, who was found to be profiting from correctly betting on the president’s public utterances. Kalshi’s internal surveillance tools flagged these suspiciously timed bets, leading to a report to federal authorities. This incident has highlighted the potential for insider trading and manipulation in mention markets.
New York City Council’s Probe into Marketing Practices
The New York City Council has launched its own investigation into the advertising practices of prediction market platforms, including Kalshi and Polymarket. Council Speaker Julie Menin has sent a lengthy list of questions to these companies, examining whether current city laws adequately protect residents from false or deceptive marketing.
The council is particularly concerned about the targeting of young adults and potentially minors through deceptive advertising. Reports have alleged that Polymarket conspired with influencers and marketing agents to create promotional videos featuring fake profitable trades. These videos were used to attract users to the platform, raising questions about the ethical implications of such marketing strategies.
The New York City Council is also looking into the social harms associated with prediction markets, particularly the potential for compulsive wagering. The council has requested detailed information from the companies, including the number of users in the state, the age and demographics of customers, and how much money New York City residents have won or lost. The companies have been given 14 days to respond, and the council plans to hold public hearings on the topic.
The Legal Battle Over Prediction Markets
The legal and regulatory battles over prediction markets have intensified in recent years. The platforms and the CFTC argue that event contracts are financial instruments that should fall under federal oversight. However, states, including New York, have disputed this idea and sued the firms, alleging that the platforms amount to illegal, unlicensed gambling operations.
The CFTC has ordered Kalshi to continue operating in New York despite the state’s efforts to shut down its operations. The CFTC maintains that it has exclusive authority to regulate prediction markets and has pushed back against New York Attorney General Letitia James’ suit against Kalshi. James has alleged that Kalshi is illegally operating a gambling app, but the CFTC has stated that the New York State Attorney General does not set the rules for national derivatives markets.
In response to the regulatory pressure, Kalshi has made overtures to New York authorities, offering a share of its trade revenue in taxes and volunteering to allow users to exclude themselves from the app. Polymarket, on the other hand, has kicked off a reorganization of its marketing team, hiring Travis VanderZanden, founder of the e-scooter company Bird, as head of growth.
As the legal and regulatory battles continue, the future of prediction markets remains uncertain. The outcomes of these investigations and lawsuits will have significant implications for the industry and its millions of users.
