Michael Burry Blasts Prediction Markets As ‘Gambling Platforms’ Operating Through ‘Regulatory Loophole.’

Investor Michael Burry has launched a sharp attack on prediction markets such as Kalshi, saying that they are effectively gambling platforms operating through a regulatory loophole and warning that retail users are vulnerable to unfair trading practices.

Burry speaks as prediction markets face growing scrutiny from researchers, lawmakers and investors over whether the platforms provide a level playing field for ordinary users and whether they should be regulated more like traditional sports betting or financial markets.

The hedge fund manager, best known for predicting the 2008 U.S. housing market collapse and whose story was chronicled in The Big Short, shared his views in a series of posts on X, shifting his focus from financial markets to the rapidly expanding prediction market industry.

“Kalshi as with all prediction markets is in a regulatory loophole within an extremely heavily taxed and excessively regulated industry that is gambling no matter what anyone calls it,” Burry wrote.

Questions Over Regulation

Prediction markets allow users to buy and sell contracts tied to the outcome of future events, ranging from elections and economic data to sporting events and weather forecasts. Unlike conventional sportsbooks, platforms such as Kalshi operate under the oversight of the U.S. Commodity Futures Trading Commission (CFTC) because they structure their offerings as event contracts rather than traditional wagers.

That regulatory distinction has enabled prediction markets to expand rapidly across the United States, even as sports betting remains subject to state-by-state regulation.

Critics argue that, regardless of their legal structure, many event contracts function much like conventional gambling products. Burry echoed that criticism, saying the current framework allows prediction markets to operate outside many of the restrictions imposed on traditional gambling operators.

Burry also challenged claims by Kalshi that its markets are better equipped to detect insider trading than traditional financial markets.

Kalshi Chief Executive Tarek Mansour has argued that suspicious trading activity is easier to identify on prediction platforms because of the transparency of their markets and transaction data.

Burry rejected that argument.

“Kalshi presents the ability to gamble and cheat, and the loophole allows all of it in every state,” he wrote.

He added that the industry’s rapid growth reflects regulatory gaps rather than superior market design.

“Of course it is number 1 by a mile and will keep growing as long as society steps aside and lets these horrific base human weaknesses run roughshod over all and any logical, moral and decent challenge.”

In another post, Burry argued that prediction markets lack sufficient safeguards against manipulation.

“There is nothing preventing cheating in prediction markets. Cheating, the only activity as old as gambling, with the same power to drive humans to extremes.”

Burry’s criticism follows renewed debate over whether retail participants can compete fairly against professional traders on prediction platforms.

Last week, the Roosevelt Institute published research estimating that ordinary users have collectively lost nearly $600 million on Kalshi since 2018. The think tank noted that a relatively small group of sophisticated traders has captured most of the profits, leaving casual participants at a structural disadvantage.

Kalshi has disputed aspects of the criticism, maintaining that its markets are transparent and operate under federal oversight.

The debate bolsters one of the industry’s central questions: whether prediction markets primarily serve as information-discovery mechanisms or whether they increasingly resemble speculative gambling platforms where experienced traders consistently outperform retail participants.

Burry is not alone in raising concerns about the industry’s regulatory framework.

Distressed debt investor Thomas Braziel has also argued that prediction markets face significant regulatory risks, describing their business model as a form of regulatory arbitrage designed to avoid state gambling laws. He has warned that future regulatory changes could materially affect the industry’s growth.

The criticism comes as prediction markets continue to expand rapidly.

Trading volumes on leading platforms, including Kalshi and Polymarket, have surged over the past year as users increasingly speculate on elections, economic releases, geopolitical developments and sporting events. The sector has attracted growing interest from retail traders seeking alternatives to traditional investing and sports betting.

At the same time, lawmakers have introduced several proposals aimed at tightening oversight of event contracts, particularly those tied to sports and elections. Some bills would prohibit certain categories of prediction contracts altogether, while others seek to establish clearer regulatory boundaries between financial products and gambling.
