Prediction markets are getting harder for Washington to ignore. All 11 Democrats on the Senate Banking Committee are calling for a public hearing on the industry after committee Republicans met privately with Kalshi CEO Tarek Mansour this week. The request puts another congressional spotlight on an industry already navigating questions about federal authority, state challenges, and where certain event contracts fit within existing financial rules.
Sens. Elizabeth Warren and Catherine Cortez Masto led the September 23 letter, and every Democrat on the committee signed it. The lawmakers argued that the full committee should examine prediction markets publicly rather than leave the discussion to a Republican-only meeting with industry representatives. No public hearing has been scheduled yet.
Kalshi Meeting Sparks a Bigger Conversation
Senate Banking Committee Republicans met with Mansour on September 23 to discuss prediction markets and securities-linked products. Chairman Tim Scott said the conversation covered financial innovation, retail investor protections, and regulatory questions Congress may eventually need to address.
That private meeting quickly drew attention from Democrats. Their letter argues that prediction markets increasingly touch areas overseen by the Banking Committee, particularly as platforms and other financial companies explore products connected to corporate performance.
The Democratic members calling for a hearing include:
- Elizabeth Warren
- Catherine Cortez Masto
- Jack Reed
- Mark Warner
- Chris Van Hollen
- Tina Smith
- Raphael Warnock
- Andy Kim
- Ruben Gallego
- Lisa Blunt Rochester
- Angela Alsobrooks
Prediction Markets Are Moving Into New Territory
The CFTC has been the federal regulator most closely associated with event contracts, but the products themselves are becoming more varied. Sports, elections, and economic indicators are only part of the growing market. Contracts connected to corporate earnings and other company-specific outcomes create another regulatory question.
Banking Committee Democrats argue some of those products could qualify as security-based swaps and therefore fall under SEC rules. The Banking Committee oversees the SEC, while congressional oversight of the CFTC primarily runs through the House and Senate Agriculture committees. That distinction helps explain why prediction markets are suddenly attracting attention from another corner of Congress.
The Democrats also raised concerns about market manipulation, insider trading, and the concentration of trader profits. Those are arguments the industry will likely have to address more frequently as event contracts move closer to traditional financial products.
One Industry, Several Regulatory Questions
The push for a hearing highlights just how complicated the regulatory picture has become. The CFTC has asserted federal authority over contracts listed on its registered exchanges, while states have challenged sports-related event contracts under their own gaming laws. Securities-linked products may also bring the SEC into the conversation.
None of this means Kalshi's regulatory status has changed, and the Democrats' letter doesn't guarantee a hearing. It does show that Congress is paying closer attention to where prediction markets fit within the broader U.S. financial system.
For you as a prediction market user, that debate matters. Which regulator oversees a particular type of contract can influence everything from disclosures and consumer protections to which products ultimately reach the market.
The Trade Handle Prediction Markets Take
More congressional attention can create headaches for prediction market companies, but it also shows how quickly the industry has grown. Prediction markets are no longer being discussed solely as an unusual corner of derivatives trading. Lawmakers are now debating how they fit alongside established financial products and regulatory systems.
The next important question is whether Scott agrees to a public hearing and, if so, who gets invited to testify. A hearing featuring regulators, industry executives, researchers, and critics could give us one of the clearest looks yet at how Congress views the future of prediction markets.
