Rennie, J. I. INTRODUCTION

Meta—the company behind social media platforms Facebook and

Instagram—is embroiled in several thousand lawsuits regarding the harm its

platforms allegedly cause children. Most of the suits have been consolidated into

two actions in California (the “Social Media Litigation”). Here in Delaware, Meta’s

state of incorporation, Meta’s insurers seek a declaration that they owe no duty to

defend Meta in the Social Media Litigation.

Two motions are before the Court: Meta’s Motion to Dismiss or Stay (“Meta’s

Motion”) and Insurers’ Motion for Partial Summary Judgment (the “Insurers’

Motion”). Meta seeks to stay this action pending resolution of the Social Media

Litigation or, in the alternative, as a matter of forum non conveniens. Conversely,

Insurers seek a summary ruling that, under California law, the allegations in the

Social Media Litigation do not trigger a duty to defend.

The Court concludes that: (i) a stay is neither required under California law

nor warranted under Delaware law, and (ii) Insurers have established that the

allegations in the Social Media Litigation do not trigger a duty to defend under the

applicable Meta insurance policies.

Accordingly, Meta’s Motion is DENIED and Insurers’ Motion is GRANTED. II. BACKGROUND
