A Democratic victory in one or both chambers of Congress would not stop the Trump administration from handing regulatory breaks to Wall Street banks, prediction markets, and crypto firms, but it would give Democrats tools to investigate those industries and their regulators, according to a Reuters report.
This matters for crypto readers because the midterm outcome could change the day-to-day environment in which exchanges, prediction-market platforms, and token issuers operate, even if the White House continues to issue favorable rules. A Democratic-controlled House or Senate would gain the ability to issue subpoenas, expand investigative staff, and compel testimony from agency heads and company executives. Those powers do not rewrite statutes, but they can slow rulemaking, force document production, and generate headlines that affect counterparties and customers.
Polls suggest Democrats are poised to win the House of Representatives and have an edge in the race for the Senate. If the party prevails in either chamber, it would gain subpoena power, larger investigative staff, and the power to call agency heads and corporate CEOs to testify. “Everything that has gone on in the first two years of this administration is fair game for investigations,” Kevin Edgar, a partner at BakerHostetler and former chief counsel of the House Financial Services Committee, told Reuters.
The administration’s financial policy agenda includes easing rules and supervision it says are too onerous and impeding economic growth, while promoting innovation that it says will boost the economy, including crypto and prediction markets. Those steps have proceeded without new legislation. A change in congressional control would not reverse them, but it would add a parallel track of oversight that companies and regulators would have to staff.
Crypto and prediction market ties under scrutiny
Democrats are already preparing to investigate Trump’s and his family’s ties to the crypto and prediction market industries, Reuters reported. They describe such dealings as a conflict of interest. The party has also pushed for more oversight of prediction markets, which it says may create new avenues for misconduct and undermine national security by allowing government insiders to broadcast confidential information. Prediction markets say they vigilantly guard against misconduct.
Asked about potential probes in a September 30 phone interview, Representative Ro Khanna, a Democratic member of the House Oversight Committee, told Reuters, “I absolutely think we need to look at these financial transactions, these crypto transactions, and see if any of our national security has been compromised.”
A spokesperson told Reuters last month that Democrats plan “to obstruct and baselessly target President Trump’s commonsense agenda.” The administration says supporting crypto and prediction market innovation will keep American jobs and capital onshore.
Concerns over Casten’s potential committee role
Crypto executives said they are especially worried that Representative Sean Casten may challenge Maxine Waters, currently the top Democrat on the House Financial Services Committee, for the chair if Democrats win the House.
Casten has been a vocal proponent of probing the administration’s crypto ties and of tougher crypto rules. In 2024 he introduced a bill curbing crypto tools he said aid money laundering. He also voted against the industry’s Clarity Act bill in 2025, saying it would put Americans at risk. “He is no friend of the industry,” Ron Hammond, head of policy and advocacy at Wintermute, a crypto trading firm, told Reuters.
Waters has previously used the committee to call bank CEOs. Casten’s record on crypto is more recent and more directly focused on the sector. The difference matters for firms that have spent the past two years building relationships with current committee leadership. A change at the top of the Democratic side would alter who sets the hearing calendar and who drafts the questions.
Other targets and oversight costs
Other likely Democratic targets include Trump’s regulators, which have relaxed oversight of lenders and pulled back on enforcement, according to the analysis. Wall Street’s role in financing the AI boom and data centers, as well as its influence on housing and other affordability issues, is also likely to draw scrutiny, attorneys and analysts said.
Senator Elizabeth Warren, the top Democrat on the Senate Banking Committee, is seen as the frontrunner to chair that committee. She has focused recent criticism on major AI companies, saying the industry has gained special access to the administration and influence over policy. Both Warren and Waters have raised concerns over affordability, including housing, and accused the administration of eroding consumer finance protections. When Waters previously ran the House committee, she called the CEOs of the largest U.S. banks to testify.
Kevin Barstow, an attorney at O’Melveny who previously handled probes while working in the Biden White House, said congressional investigators are already laying the groundwork. “Some of our clients have received letters regarding a variety of issues, including their interactions with the administration. We are preparing our clients that some of these inquiries are likely to become formal investigations,” he told Reuters, without specifying which committees or clients.
Agency heads who sit on bipartisan boards or commissions cannot completely ignore Democratic lawmakers, executives said. They may move cautiously on very contentious issues. Addressing oversight queries and preparing for testimony is often time-consuming and can distract from policy initiatives. Congressional oversight usually creates legal and advisory costs for companies, but adverse headlines are the greatest hazard, attorneys and analysts said.
Last week, shares of online trading platform Webull dropped to a near four-month low after a congressional panel published a report probing its ties to China. During hearings, CEOs can also be pressured into business changes. Big banks made changes to overdraft fees and fraud protections following previous testimony, for example, while former Wells Fargo CEO John Stumpf resigned in 2016 after hearings on the bank’s fake accounts scandal. “The biggest risks are headline risk and reputational,” Brian Gardner, chief Washington policy strategist at Stifel, told Reuters.
A Democratic House or Senate would not necessarily pass new crypto statutes. It would, however, control the calendar for hearings, the staff resources for document requests and the ability to place executives under oath. Those tools have been used in prior cycles to force changes in bank practices and to move stock prices on the day a report is released.
