Yahoo has secured a major legal victory after a federal court ruled that five plaintiffs must pursue their privacy claims through arbitration rather than class action litigation.
The case, Tyler Baker, et al. v. Yahoo Inc. and Yahoo AD Tech LLC, No. 25CV2797 (DLC), 2026 WL 2516944, was decided by a Southern District of New York court on 26 August 2026.
Six individuals had brought a class action against Yahoo, alleging the company violated privacy laws by collecting their personal information without consent after they signed up for third-party websites.
The plaintiffs claimed Yahoo harvested their data through its ConnectID targeted advertising technology, which operates across websites that have integrated Yahoo’s advertising platform.
Yahoo moved to compel arbitration after establishing that five of the six plaintiffs held active Yahoo email accounts and had agreed to Terms of Service that contained an explicit arbitration clause.
The sixth plaintiff’s account had been deactivated due to inactivity, placing that individual in a different legal position from the remaining five claimants.
Yahoo first introduced an arbitration clause into its Terms of Service in 2018, requiring all users who created accounts from that point forward to accept the Terms as part of the account creation process.
In March 2025, Yahoo updated its Terms and sent emails to all users stating that “by continuing to use Yahoo services, users accepted and agreed to these updated Terms.”
All five active-account plaintiffs were found to have accepted Yahoo’s Terms of Service across multiple versions, including those introduced in 2018, March 2025, and May 2025.
The plaintiffs argued that clicking a “Continue” button during account sign-up did not constitute genuine legal assent because the interface lacked a dedicated checkbox or comparable confirmation mechanism.
The court firmly rejected that argument, finding that users facing a virtually identical sign-up screen were “on inquiry notice of the arbitration provision.”
The ruling underscores the growing legal weight courts are placing on click-through agreements, reinforcing that digital acceptance can constitute a binding contractual commitment.
The court also granted Yahoo’s motion to stay proceedings pending arbitration, effectively pausing the class action claims brought by the five active account holders.
The decision is likely to be closely watched by technology and advertising companies that rely on similar Terms of Service structures to manage consumer disputes and limit class action exposure.
