Prosper Marketplace Historic Lawsuit
Below is a breakdown of some of the most significant lawsuits and regulatory actions that have shaped the legal landscape for Prosper Marketplace.
Prosper Marketplace, a leading peer-to-peer lending platform, has faced numerous legal challenges and regulatory actions over the years. These lawsuits primarily involve issues such as unregistered securities offerings, misleading investor information, consumer protection violations, and more recently, data breaches.
Key Historic Lawsuits and Regulatory Actions
Unregistered Securities Offerings
Between 2006 and October 2008, Prosper Marketplace was involved in offering and selling promissory notes that were classified as unregistered securities. This practice violated both federal and state laws, leading to regulatory scrutiny. The issue came to a head when the Securities and Exchange Commission (SEC) issued an administrative order against Prosper in November 2008.
Prosper agreed to cease and desist from future violations and consented to the SEC’s order without admitting or denying the findings. The company also agreed to properly register its securities in the future to comply with federal regulations.
In addition to the federal action, Prosper faced investigations from a group of state securities regulators from around 20 states, including Alabama, Washington, and South Carolina. The company eventually entered into settlements with these states, agreeing to register its securities and pay administrative assessments and investigation costs.
Class-Action Lawsuit
In 2008, a class-action lawsuit (CGC-08-482329) was filed in San Francisco Superior Court. The suit was brought on behalf of loan note purchasers during the period when Prosper had sold unregistered securities. The plaintiffs alleged that Prosper violated California and federal securities laws by failing to properly register its securities.
This lawsuit was settled in July 2013 for $10 million, resolving claims that Prosper had misled investors by selling unregistered securities. This case highlighted concerns over Prosper’s earlier business practices and the company’s handling of securities laws.
Misleading Investor Returns
In 2019, Prosper Funding LLC faced regulatory action from the SEC over misleading investor returns. The SEC charged that Prosper had provided inaccurate annualized net return (ANR) data to over 30,000 investors between July 2015 and May 2017. Prosper had displayed returns that excluded defaulted loans from its calculations, which created a misleading picture of the platform’s performance and investor returns.
To settle the charges, Prosper agreed to pay $3 million, although the company did so without admitting or denying the SEC’s findings. The settlement underscored concerns about transparency in how Prosper reported financial performance to investors and raised questions about its responsibility to provide accurate and honest return data.
Disability Discrimination Lawsuit
In 2015, Prosper was named in a lawsuit filed by Larry Whitt, who claimed that the company had discriminated against him based on his disability in violation of the Americans with Disabilities Act (ADA). Whitt alleged that Prosper’s practices made it difficult for him to access or use the platform, violating his rights under the ADA.
Prosper moved to compel arbitration, and the case was eventually stayed or dismissed in favor of arbitration, meaning the matter was to be resolved outside of court. This case highlighted potential issues with Prosper’s accessibility practices and the company’s obligations to ensure that individuals with disabilities can use its services.
Consumer Protection and Licensing Lawsuits
In 2021, a class-action lawsuit was filed against Prosper Marketplace in Maryland. The lawsuit alleged that the company violated various state consumer and debt collection laws. Specifically, the plaintiffs claimed that Prosper was unlicensed in Maryland and had made misrepresentations regarding its authority and the fees it charged.
The lawsuit raised serious concerns about Prosper’s compliance with state-level licensing requirements and its transparency in business practices. If the lawsuit is successful, it could result in financial penalties and greater oversight of Prosper’s operations in Maryland and other states.
Data Breach and Privacy Lawsuits
In late 2025, multiple data breach class-action lawsuits were filed against Prosper following a massive security breach. Reports indicated that sensitive personal information of 17.6 million customers was exposed as a result of inadequate security measures. The breach allegedly compromised user data such as Social Security numbers, addresses, and financial information, leading to a flurry of legal action.
The lawsuits, including one filed by Taylor v. Prosper Funding, LLC, allege that Prosper was negligent in implementing sufficient security protocols to protect its users’ data. If the plaintiffs are successful, Prosper could face significant financial penalties and be required to implement stricter data protection measures moving forward. The outcome of these lawsuits may have widespread implications for how financial technology companies handle and protect customer data.
Prosper Marketplace’s Ongoing Legal Struggles
Prosper Marketplace has faced a number of significant legal and regulatory challenges over the years, ranging from securities violations to consumer protection issues and data breaches. These legal battles highlight the complexity of operating a peer-to-peer lending platform, where compliance with both federal and state laws is critical.
As the company works to resolve ongoing lawsuits and regulatory scrutiny, consumers, investors, and other stakeholders must be aware of their rights and consider taking action if they have been affected by Prosper’s practices.
