Why the Senate seeks a prediction market hearing this week comes down to one letter and one closed-door meeting. Democrats want lawmakers to examine event-based trading in public, while Republicans chose a private conversation with an industry executive. The dispute shows how unsettled the rules remain for a fast-growing corner of finance.
At a Glance
All 11 Democrats on the Banking Committee asked Chairman Tim Scott for a public hearing on September 23, 2026.
The same morning at 10 a.m., Scott and Republican members met privately with Kalshi Prediction Market CEO Tarek Mansour.
Democrats say event contracts tied to company results may fall under SEC oversight.
No hearing has been announced.
All eleven Democrats on the Banking Committee signed a letter to Chairman Tim Scott on Wednesday, September 23, 2026. They said the panel has a "critical oversight role to play." Ranking Member Elizabeth Warren and Catherine Cortez Masto led the effort.
Other signers were Jack Reed, Mark Warner, Chris Van Hollen, Tina Smith, Raphael Warnock, Andy Kim, Ruben Gallego, Lisa Blunt Rochester and Angela Alsobrooks.

The request arrived the same day Scott and fellow Republicans sat down with Kalshi's Tarek Mansour, a meeting first reported by Punchbowl News. Democrats criticized what they called a Republican-only, industry-friendly roundtable and said the topic should not be handled "behind closed doors."
Scott said he wanted to understand securities-linked products. He pointed to innovation, retail investor protection and the need for regulatory clarity.
Issue | Democrats | Scott and Republicans |
Format | Public hearing | Private meeting |
Participants | All 11 Democratic members | Scott, Republican members, Mansour |
Focus | Consumer and financial-system impact | Innovation and investor protection |
Concern | SEC oversight of securities-linked products | Clear rules for new products |
The Commodity Futures Trading Commission has claimed a leading role over these platforms. The House and Senate Agriculture Committees hold primary jurisdiction over that agency. The Banking Committee, however, oversees the SEC, so it would cover anything classified as a securities-linked product. Democrats argue that contracts tied to company performance indicators could land in that category.
The letter says event contracts linked to corporate performance could meet the definition of security-based swaps, which the SEC regulates. The timing matters. Bloomberg reported in July that Cboe Global Markets asked the SEC whether it could list all-or-nothing options tied to company earnings. Those products create a possible overlap between agencies. Whether they cross the legal line is a question for regulators, not something the reports settle.
Separate from the securities debate, the CFTC faces pushback from states. They argue they hold authority over sports event contracts. That fight continues, and the two Agriculture Committees have weighed the subject over the past year. Congress is therefore approaching the issue from several directions at once.

The Democrats' letter cites experts who warn that these platforms may invite prediction market manipulation and crypto insider trading. It also references early research suggesting profits are concentrated among a small share of users while most lose money. These are warnings and preliminary findings, not settled conclusions. They do overlap with Scott's own stated interest in protecting retail investors.
Federal agencies, state regulators, and multiple congressional committees now all have a stake. That is why Senate Banking Committee involvement matters mainly for securities-linked products. It does not imply exclusive authority over the whole sector.
Democrats have formally asked for a public hearing. The available reports do not show that Scott has agreed to one. Further discussion in Congress will likely determine whether securities-linked contracts get formal scrutiny.
Date | Development |
July 2026 | Bloomberg reports Cboe's request to the SEC on earnings-linked options |
Sept. 23, 2026 | Democrats send Prediction Market hearing request to Scott |
Sept. 23, 2026 | Republicans meet privately with Kalshi CEO |
Ongoing | CFTC and states dispute authority over sports contracts |
The letter gives Democrats a formal position, and the Kalshi meeting gives Republicans their own view of the industry. Whether a public hearing follows will show how seriously the committee treats securities-linked event contracts. Crypto market Readers should watch for any response from Scott or a scheduling notice.
