Meta’s Social Media Addiction Lawsuits Trigger a Major Legal Battle: Who Pays for the Defence Costs?

As Meta and other tech giants battle thousands of lawsuits accusing them of designing social media platforms to addict young users, a parallel legal war is unfolding in Delaware — one that could determine who pays for that defence. At stake is whether insurers must fund what could become hundreds of millions of dollars in legal costs, even when the underlying claims allege deliberate misconduct.

More than 20 insurers, led by The Hartford and Chubb, argue they have no obligation to bankroll Meta’s defence. While companies routinely purchase liability insurance to cover litigation costs, the insurers contend those policies do not apply where the alleged harm stems from intentional acts rather than accidents.

In a pre-emptive move, the insurers sued Meta in Delaware Superior Court in late 2024. Earlier this year, they secured an initial victory when the court ruled that they had no duty to defend the parent company of Facebook and Instagram. The case is now headed to the Delaware Supreme Court on appeal.

At the heart of the dispute lies a familiar but commercially significant insurance question: when do negligence allegations trigger a duty to defend?

The social media addiction lawsuits accuse Meta of deliberately engineering platform features to exploit teenagers’ developing brains and encourage compulsive use. Insurers argue such conduct cannot be classified as accidental, placing it outside the scope of liability coverage.

Meta, however, insists the underlying lawsuits also contain negligence claims — alleging a failure to exercise reasonable care — and maintains it never intended to harm users. Under California law, the company argues, that should be enough to compel insurers to cover its defence costs.

The dispute mirrors earlier insurance battles during the opioid litigation era, where drugmakers and pharmacies fought similar coverage claims. In many of those cases, courts held that insurers were not required to defend allegations rooted in deliberate conduct or public-harm claims, often leaving companies to shoulder enormous legal bills.

That precedent could prove costly here. Legal experts warn that if the Delaware ruling stands, it may significantly weaken the position of tech companies facing addiction-related claims.

The financial stakes are already becoming clearer. In March, a jury in Los Angeles found Meta and YouTube liable for $6 million in damages in an early bellwether trial. The plaintiff, now 20, argued she became addicted to their platforms as a child due to manipulative product design, resulting in depression, anxiety and other mental health issues.

A judge later rejected the companies’ request for a new trial, and both defendants have indicated they will appeal.

That bellwether verdict is widely seen as a potential blueprint for future claims — not only from affected users and families, but also school districts, local governments and state attorneys general pursuing broader public harm actions.

The scale of the litigation is already vast. Meta and other social media companies face nearly 3,300 consolidated cases in California state court, along with another 2,400 cases in federal multidistrict litigation in Oakland.

In a detailed 58-page ruling delivered in February, Delaware Superior Court Judge Sheldon Rennie concluded the insurers had no duty to defend. He framed the central question as whether the underlying harms were caused by an “accident” — a requirement under Meta’s liability policies.

Although the lawsuits include negligence claims, Rennie ruled that labels alone do not trigger coverage where the alleged conduct itself was intentional.

“The platforms were specifically engineered to maximise engagement,” he wrote, concluding it was not “mere fortuity” that those design choices allegedly caused harm.

Meta has since appealed, arguing the judge misapplied California law and wrongly treated contested factual allegations as settled. Its lawyers from Covington & Burling and Berger McDermott say the company never conceded that its design choices were intended to increase child engagement, maintaining instead that its goal was simply to improve user experience.

The appeal will not determine whether Meta is legally responsible for social media addiction. But it could answer a question just as important to the litigation itself: who pays for the fight. And in mass litigation, that answer often shapes how long companies can resist — and how quickly they may choose to settle.
