**Topstep LLC Data Breach Exposes Sensitive Customer Information**
In December 2025, Topstep LLC, a Chicago-based financial services firm specializing in proprietary trading, disclosed a data breach that potentially compromised the personal information of 222 individuals in Texas. The breach was reported to the Texas Attorney General’s office on December 22, 2025, with affected consumers notified via U.S. Mail.
Topstep, founded in 2012, operates a platform allowing retail futures traders to qualify for funding through a simulated evaluation program. While the company is not a licensed broker and remains unregulated, it serves a large community of traders, generating revenue through subscription and reset fees.
The exposed data may include names, addresses, Social Security numbers, and other sensitive personally identifiable information (PII). The law firm Shamis & Gentile P.A. is investigating the incident, noting that affected individuals may be eligible for compensation due to the breach.
Topstep has not publicly detailed the cause or full scope of the breach, but the incident underscores the risks associated with unregulated financial platforms handling sensitive consumer data.
