Federal Court Lets Class Action vs. Temu on Data Sharing Proceed

An Illinois federal court denied dismissal of a class action against Temu and Index Exchange.

On June 17, 2026, a federal judge in Illinois rejected a motion to dismiss a class action lawsuit targeting Temu and the advertising platform Index Exchange. The suit accuses the defendants of illegally intercepting communications of website visitors and unlawfully sharing personal data via real-time advertising and cookie syncing.

These allegations come in the context of previous regulatory actions against Temu. In September 2025, the company settled allegations of violating the INFORM Consumers Act by agreeing to pay a $2 million civil penalty. The FTC stated the act "is designed to ensure consumers have the information and tools they need to not only report suspicious activity to online marketplaces, but to directly identify and contact high-volume, third party sellers in many cases," as explained by Christopher Mufarrige, Director of the FTC’s Bureau of Consumer Protection.

Moreover, in April 2026, Temu faced additional class-action lawsuits alongside Shein, accusing them of raising prices to offset tariffs on Chinese imports that were later ruled unlawful. These lawsuits seek consumer refunds tied to those price increases.

This ongoing litigation highlights increased scrutiny of online marketplaces regarding their compliance with privacy, consumer protection laws, and data handling practices in advertising. Legal professionals should monitor how these cases shape regulatory expectations around data transparency and user consent in digital advertising.
