Clerk's notes
Topstep LLC, a proprietary trading firm operating in Indiana, officially reported a data security incident on January 20, 2026. The breach, which occurred on December 14, 2025, involved unauthorized access to sensitive user data, according to filings made with the Indiana Attorney General. The investigation into this incident remains in a monitoring status.
The compromised datasets from Topstep LLC include highly sensitive personal and financial information. Specifically, the breach exposed individuals' Full Name, Social Security Number, Date of Birth, Banking and Direct Deposit Details, Government-Issued Identification, Email Address, Physical Address, and Trading Account Credentials. This extensive exposure creates significant vulnerabilities for affected parties.
Such a comprehensive data compromise places individuals at an elevated risk of identity theft, financial fraud, and account takeover. Exposed Banking and Direct Deposit Details, combined with Government-Issued Identification, could lead to unauthorized transactions or fraudulent credit applications. Trading Account Credentials may also be misused, potentially leading to unauthorized activity within proprietary trading accounts.
Given the sensitive nature of the information it handles, Topstep LLC was legally obligated to implement and maintain robust security measures to protect consumer data. The occurrence of this breach suggests potential shortcomings in the company's data protection protocols. Individuals who received a breach notification letter may have grounds to explore legal recourse.
If you received notification from Topstep LLC about this data breach, it confirms that your personal information was compromised. You do not need to have already experienced financial loss or identity theft to investigate your legal options. We encourage affected individuals to request a free case review to understand their rights and potential next steps.
