12:48 PM EDT, 10/21/2025 (MT Newswires) -- Meta Platforms ( META ) CEO Mark Zuckerberg, Snap (SNAP) CEO Evan Spiegel, and Instagram CEO Adam Mosseri will need to testify in the first trial on the adverse effects of social media on younger users, multiple media outlets reported Tuesday, citing a ruling from Judge Carolyn Kuhl of the Superior Court of Los Angeles County.

Kuhl wrote that the CEOs' testimonies would be "uniquely relevant" in the legal case, in which the social media platforms are accused of deliberately creating addictive features that have a negative impact on children's mental health, the outlets reported.

Company representatives on Monday had sought to prevent the CEOs from testifying, according to the reports.

Meta and Snap did not immediately reply to requests for comment from MT Newswires.
