Customer Seeks $431K in Dispute Against Matthew Gross and Wells Fargo

Wells Fargo Advisors and their representative, Matthew Garret Gross (CRD #4763385), have recently attracted attention due to a significant customer complaint involving allegations of investment fraud and failure to protect against scam-related activity. For investors, trust is an essential part of any financial relationship. When a customer entrusts their future to a financial advisor, the expectation is vigilance, transparency, and unwavering protection—expectations that become especially important when fraud is suspected.

Overview of the Allegations Against Matthew Garret Gross

On June 18, 2026, a review of the FINRA BrokerCheck report for Matthew Garret Gross revealed a pending customer complaint. According to the disclosed records, this dispute centers around allegations that Gross, currently registered with both Wells Fargo Advisors and Wells Fargo Clearing Services, LLC, failed to adequately protect a client after they reported unusual activity suspected to be linked to a scam. Notably, the suspicious activity reportedly began as far back as June 2025, but the arbitration was not officially filed until April 22, 2026, nearly a year later.

The customer’s complaint specifically alleges that Matthew Gross and Wells Fargo did not take sufficient action when concerns about the suspicious activity were raised, and further brings up issues of failure to supervise and breach of fiduciary duty. Claims like these cut to the core of what investors expect from their advisors—oversight, security, and quick response when trouble arises. The result is an unresolved claim seeking significant damages, which remains under arbitration as of June 18, 2026. No findings or regulatory actions have been made against Gross thus far.

The Broader Impact of Investment Fraud

This case against Matthew Garret Gross is not an isolated incident. According to the U.S. Securities and Exchange Commission (SEC) and other financial watchdogs, investment fraud continues to impact thousands of American families annually. Estimates suggest that U.S. investors lose over $50 billion every year to fraudulent advisors and misleading financial advice. While the majority of advisors act in good faith, stories like this highlight the importance of vigilance and the need for robust protections within the financial industry.

Studies have shown that the most common ways investors can lose money to bad advice include:

• Failure of an advisor to act on red flags or suspicious activity raised by clients
• Excessive trading or “churning” to earn commissions, regardless of client needs
• Sale of unsuitable investment products
• Misrepresentation or omission of crucial risks
• Poor supervision and lack of compliance controls among firms

The story of the pending complaint against Matthew Garret Gross is a stark reminder of these risks, emphasizing why regulatory safeguards matter—and why investors must be proactive when safeguarding their interests.

Relevant FINRA and SEC Rules Explained

The allegations in the pending case against Matthew Garret Gross directly engage several key industry standards. Here is a summary of some crucial investor protection rules:

• FINRA Rule 2010 (Standards of Commercial Honor and Principles of Trade): Requires every broker to observe high standards of integrity and fairness. When clients report scams or suspicious activity, these rules demand a swift and honest response.
• FINRA Rule 2090 (Know Your Customer Rule): Mandates brokers to know the essential facts about their customers, especially when identifying irregularities or new risks. Failure to respond to red flags is a serious concern under this rule.
• SEC’s Regulation Best Interest (Reg BI): Since June 30, 2020, Reg BI has required that broker-dealers act in the best interests of retail customers at all stages of the investment process. Its four core obligations include: disclosure, care, conflict of interest, and compliance. Advisors must use reasonable diligence to protect client interests above personal or firm profit.
