In a decisive step to curb potential conflicts of interest, bipartisan lawmakers have introduced a new bill aimed at preventing members of Congress, the President, and other key executive officials from trading in prediction markets. The legislation, known as the Preventing Real-time Exploitation and Deceptive Insider Congressional Trading Act, or PREDICT Act, was shared exclusively with POLITICO.
The bill is spearheaded by Reps. Nikki Budzinski (D-Ill.) and Adrian Smith (R-Neb.) and extends to include not only members of Congress but also their dependents and spouses, senior congressional staff, political appointees, and senior executive branch employees. Designed to reinforce transparency and integrity, the legislation reflects growing concerns over the misuse of insider information in profit-making from prediction markets.
"The American people are tired of politicians using their influence for personal gain, and the rise of prediction markets has made those concerns even more relevant," stated Rep. Budzinski. This concern is echoed in the recent activities on platforms like Polymarket and Kalshi, where there have been disturbing instances of profits being made from sensitive information, such as the duration of government shutdowns or international conflicts.
In response to these issues, the largest prediction market platforms, Polymarket and Kalshi, have begun implementing new measures to prevent insider trading. Polymarket has updated its rulebook to prohibit trades based on influence or confidential information, while Kalshi has introduced tools to block political candidates from betting on their own campaigns. A notable incident last month saw a California politician banned from Kalshi after placing bets on his gubernatorial campaign.
Adding to the legislative momentum, Sens. John Curtis (R-Utah) and Adam Schiff (D-Calif.) have also recently proposed a bill to ban sports betting contracts on prediction markets in the Senate.
"Our commonsense, bipartisan bill will give Americans confidence that the decisions of their elected officials are guided by merit, not personal profit," said Rep. Smith. The proposed legislation also includes stringent penalties for violations, imposing a fine of 10 percent of the transaction value and mandating that any profits are surrendered to the U.S. Treasury.
This legislative push coincides with a surge in interest from big investors in Wall Street and Silicon Valley in the rapidly expanding prediction markets. Interestingly, the sector has also attracted attention from high-profile figures such as Donald Trump Jr., who serves as an adviser to both Kalshi and Polymarket and is involved in related venture capital activities.
As the prediction market landscape continues to evolve, this legislative effort represents a significant step towards ensuring that those in power cannot use their privileged positions for personal financial gain, thereby aiming to restore public trust in political decision-making processes.
