Instagram CEO Adam Mosseri expected to testify in Meta child addiction trial

Meta Platforms’ Instagram chief executive, Adam Mosseri, is expected to take the witness stand on Tuesday in a legal case that centers on allegations that the company designed Instagram and Facebook in ways intended to be addictive to children, according to a report by Yahoo Finance.

The matter is framed as a dispute over whether Meta built features and systems on its platforms with insufficient regard for children’s wellbeing. The Yahoo Finance report says Mosseri’s testimony is scheduled for Tuesday as part of the trial process.

The case comes as regulators, lawmakers, and consumer advocates have increasingly pressed large social media companies to explain how their products affect minors. For Meta, the allegations are particularly sensitive because Instagram and Facebook are core parts of its family of apps and because Mosseri oversees Instagram’s product direction.

While Mosseri’s appearance indicates the company may put senior product leadership behind its defense or explanation, the report does not provide details in the packet here about what specific topics he will address, what materials will be discussed, or how Meta plans to respond to particular claims about engagement mechanisms.

Beyond Mosseri’s role, the lawsuit’s allegations as described in the report are closely tied to the concept of “addiction” or addictive use, a phrase often used in public debates about persuasive design features and engagement incentives. In court, such issues typically hinge on internal product decisions, data use, and how companies balance engagement goals against safety considerations for minors, though the extent of what is at issue was not detailed in the available description.

Meta has not disclosed, in the material provided here, any additional information about the testimony agenda or any substantive statements about the case. The report also does not indicate whether the company disputes the claims, which specific product features are being challenged, or what evidence the plaintiffs or defense expects to rely on.

For context, Meta’s corporate communications tend to highlight safety efforts, policies, and product changes around teens and younger users, but no such specific assurances or updates were included in the information provided for this story.

What remains unclear is whether the trial will produce new public details about internal metrics, product experiments, or safety review processes, and whether the court record will include testimony beyond general statements about product design. Observers will likely watch Tuesday’s testimony for how directly Mosseri addresses the alleged link between platform design and children’s compulsive use, and whether it prompts further questions about internal decision-making.
