More Perfect Union's investigation into prediction markets Polymarket and Kalshi reveals concerns over accuracy, insider trading, and regulatory issues.
A recent video investigation by More Perfect Union (MPU) has raised concerns about prediction markets, particularly focusing on Polymarket after its proposal to incorporate its odds into MPU's reports.
Rather than forming a partnership, MPU journalists examined Polymarket's business practices and public statements from CEO Shane Kaplan. They suggested that these platforms take advantage of Americans' economic fears, claiming to "democratize finance" while falling short.
Inaccurate Predictions Highlighted
The investigation cited a Vanderbilt University study regarding the accuracy of predictions surrounding the 2024 U.S. elections, revealing that Polymarket achieved only 67% accuracy, while Kalshi fared slightly better at 78%. In comparison, the older platform PredictIt boasted an impressive 93% accuracy rate.
Kaplan had previously touted prediction markets as "the most accurate tool humanity has at the moment" during a 60 Minutes interview. However, the investigation pointed out discrepancies, such as a significant overestimation in February's U.S. jobs report, where the market predicted an increase of 60,000 jobs, but the actual figure diverged by 150,000.
Concerns About Insider Trading
Economist Robin Hanson noted in a video that insider trading is prevalent in these markets. U.S. Senator Chris Murphy criticized the fairness of prediction markets related to government actions, stating, "All bets on government actions are rigged because someone in the government knows the outcome." He argued that it is unjust to allow contracts to be traded when the outcome is already known to a select few.
In response to concerns about insider trading, both Kalshi and Polymarket announced new initiatives. However, experts expressed skepticism about the platforms' ability to effectively monitor potential insider trading across various markets.
Profit Disparities in Trading
MPU's investigation revealed that a mere 0.04% of traders account for approximately 70% of profits in these markets. A report from Citizens Bank indicated that users of prediction markets tend to lose more in their first three months than those using traditional sportsbooks. Dustin Gouker, a journalist specializing in the gambling industry, emphasized that the majority of Kalshi's trading volume is derived from sports, while Polymarket has around 40% from that sector, characterizing the platforms as gambling operations.
Regulatory Challenges and Lobbying Efforts
Federal oversight by the U.S. Commodity Futures Trading Commission (CFTC) allows these platforms to evade local taxes and player protection regulations. In contrast, New York bookmakers face a hefty 51% tax and must implement measures to combat gambling addiction. This regulatory disparity has led to legal battles, with Kalshi facing lawsuits from multiple states over its classification as unlicensed gambling. Despite this, the CFTC continues to uphold the current regulatory framework, with Donald Trump Jr. serving as a strategic advisor for both Polymarket and Kalshi.
In a notable move, Polymarket opened a free grocery store in New York, a tactic viewed by MPU journalists as an effort to garner positive publicity for the gambling platform.
