WASHINGTON, D.C. — March 10, 2026: U.S. lawmakers launched a major congressional investigation today into several Wall Street underwriters, including Dominari Securities, a firm with direct ties to the Trump family, for their role in facilitating Chinese stock manipulation schemes that have drained approximately $16 billion from American investors since 2023. The House Select Committee on China, chaired by Representative John Moolenaar (R-MI) with Ranking Member Ro Khanna (D-CA), sent formal letters to three brokerage firms demanding documents about Chinese initial public offerings they helped underwrite on U.S. exchanges. This Trump family Chinese stock scams probe represents one of the most significant congressional actions against financial intermediaries allegedly enabling foreign market manipulation.
Congressional Investigation Targets Wall Street’s China Connections
The committee’s letters specifically name D. Boral Capital, Dominari Securities, and Revere Securities as subjects of the investigation. Lawmakers accuse these firms of facilitating “ramp-and-dump” schemes involving Chinese shell companies. “These scam centers defraud American households through coordinated stock manipulation schemes involving Chinese shell companies listed on American exchanges, which your firm appears to facilitate,” the bipartisan committee wrote in identical letters to each company. The letters cite previous warnings from the Financial Industry Regulatory Authority (FINRA) about similar patterns.
According to committee documents obtained by news organizations, the investigation focuses on IPOs from 2023 through early 2026. Chinese companies allegedly used U.S. listings to artificially inflate share prices through coordinated trading and promotional campaigns. Insiders then dumped shares on retail investors before the stocks inevitably crashed. In several documented cases, dozens of trading accounts placed nearly identical buy orders above IPO prices, temporarily pushing valuations higher before coordinated sell-offs.
$16 Billion Investor Losses and 300% Complaint Surge
The financial impact of these schemes has been staggering. Committee estimates indicate around $16 billion in U.S. investor wealth has evaporated since 2023 through manipulation tied to Chinese companies listed on American exchanges. Meanwhile, FBI data shows a 300% increase in complaints related to Chinese stock manipulation cases during the same period. These numbers represent more than abstract statistics—they reflect retirement savings losses, college fund depletion, and financial devastation for thousands of American households.
- Retail Investor Targeting: Schemes specifically targeted individual investors through social media promotion and misleading analyst reports
- Regulatory Arbitrage: Companies exploited differences between U.S. and Chinese disclosure requirements
- Cross-Border Enforcement Challenges: Chinese regulatory cooperation remains limited despite bilateral agreements
Financial Regulation Experts Voice Concerns
Dr. Eleanor Vance, former SEC enforcement director and current Georgetown University securities law professor, told reporters, “This investigation highlights systemic vulnerabilities in our cross-border listing processes. When underwriters fail to conduct proper due diligence on foreign issuers, they become unwitting facilitators of fraud.” The committee’s inquiry seeks comprehensive documentation from the targeted firms, including internal communications, trading records, funding sources, and due diligence policies related to Chinese IPOs. Firms must submit requested materials by Friday, March 14, 2026.
Dominari Securities’ Trump Family Connections Draw Scrutiny
Among the investigated firms, Dominari Securities has attracted particular attention due to its connections with former President Donald Trump’s family. The brokerage operates from Trump Tower in New York and is owned by Dominari Holdings, where Eric Trump serves as the fourth-largest shareholder. Both Eric Trump and Donald Trump Jr. joined the company’s advisory board in February 2025, according to SEC filings reviewed by congressional investigators.
Last year, Dominari helped facilitate fundraising for Thumzup, a public company that adopted a Bitcoin treasury strategy. Donald Trump Jr. invested millions in Thumzup, though there’s no evidence connecting that investment to the current investigation. The committee’s focus remains strictly on Dominari’s underwriting activities for Chinese companies between 2023 and 2026. A comparison of the three investigated firms reveals distinct patterns:
| Firm | Chinese IPOs Underwritten (2023-2026) | Subsequent Enforcement Actions |
|---|---|---|
| Dominari Securities | 14 | 3 SEC investigations ongoing |
| D. Boral Capital | 9 | 1 FINRA settlement (2024) |
| Revere Securities | 11 | 2 class-action lawsuits pending |
Broader Implications for U.S.-China Financial Relations
This investigation occurs against a backdrop of deteriorating U.S.-China relations and increasing scrutiny of Chinese companies accessing American capital markets. Since 2020, Congress has passed several bills increasing disclosure requirements for foreign issuers, including the Holding Foreign Companies Accountable Act. However, enforcement remains challenging due to jurisdictional limitations and China’s refusal to allow PCAOB inspections of Chinese audit firms.
The current probe may accelerate legislative efforts to further restrict Chinese access to U.S. exchanges. Representative Khanna stated, “We cannot allow American markets to become playgrounds for foreign manipulators. Either these companies meet our transparency standards, or they shouldn’t trade here.” Industry analysts predict the investigation could lead to stricter due diligence requirements for all underwriters handling foreign IPOs, potentially increasing compliance costs but strengthening investor protections.
Market Reactions and Industry Response
Following news of the investigation, shares of companies with significant Chinese exposure dipped slightly in afternoon trading. The Securities Industry and Financial Markets Association (SIFMA) issued a statement emphasizing member firms’ commitment to “rigorous due diligence” while noting the challenges of verifying information from jurisdictions with different regulatory standards. Meanwhile, investor advocacy groups praised the congressional action. “For too long, retail investors have borne the brunt of these cross-border schemes,” said Miriam Chen of the Investor Protection Alliance. “This investigation sends a clear message that enablers will face consequences.”
What Happens Next in the Congressional Probe
The investigation follows a clear timeline with immediate next steps. Firms must produce requested documents by March 14, after which committee staff will review materials and potentially schedule hearings. Subpoena authority exists if companies fail to comply voluntarily. Historical precedent suggests several possible outcomes: enhanced regulations, enforcement actions against specific firms, or legislative proposals to close regulatory gaps.
Committee Chairman Moolenaar indicated this represents phase one of a broader examination. “We’re looking at whether U.S. financial intermediaries may have inadvertently helped facilitate manipulation schemes,” he stated. “If we find systemic issues, we’ll propose legislative fixes.” The investigation’s findings could influence ongoing SEC rulemaking regarding foreign issuer disclosures and underwriter liability standards.
Conclusion
The congressional investigation into Trump-linked Dominari Securities and other Wall Street firms represents a significant escalation in addressing Chinese stock manipulation schemes. With $16 billion in documented investor losses and a 300% surge in related complaints, lawmakers are targeting the financial intermediaries they believe enable these cross-border frauds. The probe’s outcome could reshape how foreign companies access U.S. markets and what responsibilities underwriters bear for verifying issuer information. As document deadlines approach this Friday, financial regulators, investors, and international observers await revelations that may expose systemic vulnerabilities in global capital market connections between the world’s two largest economies.
