  "account": "The European Securities and Markets Authority has warned in its latest risk report that prediction markets are riddled with insider trading. This is a claim that challenges the assertions made by supporters of these markets, including President Trump and Donald Trump Jr. The Authority notes that the promoters of prediction markets, such as Michael S. Selig, Chairman of the Commodity Futures Trading Commission, and the Trump family, are not immune to the dangers of insider trading. They argue that when insiders trade based on advanced knowledge of events, the prices in the market no longer accurately reflect the true probabilities of those events. For instance, if Fed officials participate in prediction markets, their involvement could compromise the objectivity of the market's pricing. This issue was highlighted when two Fed officials were found to have engaged in extensive stock trading in 2020 while the Fed was overseeing trillions of dollars in financial stabilization. Furthermore, Donald Trump Jr.'s investment firm, 1789 Capital, recently purchased shares in Polymarket, a prediction market, despite its U.S. trading restrictions. This development exemplifies the corrupting influence of big players in prediction markets, which in turn undermines their ability to reliably track objective truth. The presence of big players, such as Fed officials and U.S. Presidents and their associates, in these markets threatens to erode their credibility and hinder rational planning for individuals and institutions.",
