U.S. Senators introduce multiple bills targeting prediction markets with a focus on insider trading and market integrity issues.
Legislative Actions Unfold
Between March 23 and March 26, Congress introduced three legislative proposals aimed at tightening the regulations around prediction markets. On March 23, Senators Adam Schiff and John Curtis unveiled the Prediction Markets Are Gambling Act. This bill seeks to prohibit CFTC-registered platforms from offering sports and casino-style contracts. Backed by the Indian Gaming Association, the proposal emphasizes applying insider trading rules to prediction markets to prevent public officials from exploiting sensitive information for profit.
Just two days later, a bipartisan House bill emerged, targeting the participation of members of Congress, the president, and executive branch officials in trading political event contracts. On March 26, Senators Jeff Merkley and Elizabeth Warren introduced the STOP Corrupt Bets Act, which aims to curb trading on elections, government actions, and military conflicts. Representative Jamie Raskin joined the legislative effort, underscoring the sentiment that lawmakers should not engage in markets influenced by their own policy decisions.
Industry Reactions and Moves
Kalshi, a key player in the prediction markets, responded critically to the Schiff–Curtis bill, viewing it as an attempt to protect traditional gambling interests. CEO Tarek Mansour argued that banning regulated prediction markets would drive users to unregulated offshore platforms, thus harming consumer protection. On March 23, Kalshi preemptively blocked athletes, coaches, and political candidates from trading contracts related to their own events. This measure aims to enhance market integrity, although Senators Schiff and Curtis dismissed these efforts as inadequate.
Polymarket updated its rules the same day, prohibiting trades based on stolen confidential information or illegal tips. Neal Kumar, Polymarket’s chief legal officer, stated that these changes clarify user expectations. Despite these updates, the legality and ethical concerns continue to surface as lawmakers and platforms debate the adequacy of self-regulation versus legislative oversight.
Funding and Market Dynamics
Amidst regulatory scrutiny, a new venture fund, 5(c) Capital, raised $35 million to bolster prediction markets infrastructure. Notable investors include Kalshi CEO Tarek Mansour and Polymarket CEO Shayne Coplan, highlighting a rare collaboration in a competitive landscape. The fund’s focus remains on developing the market’s underlying infrastructure, including market-making and data products, rather than consumer-facing platforms. This development aligns with Crypto Markets Show Recovery Signs as, highlighting broader market trends.
These developments come as blockchain analytics firm Bubblemaps uncovered a trader suspected of leveraging insider information, securing nearly $967,000 on Polymarket through strategic bets on geopolitical events. This incident fuels the ongoing debate on market integrity and the role of information in driving market movements.
As prediction markets navigate their regulatory environment, the pace of legislative and judicial actions varies significantly. While platforms rapidly adjust their policies, legislative measures advance more deliberately. Courts, meanwhile, manage disputes on a case-by-case basis, as seen with recent legal actions against Kalshi in Arizona and Nevada.
