Social Media Addiction Litigation: Ongoing Coverage of MDL 3047

This is an ongoing story. 411 Press updates this coverage as the litigation develops. Last updated: May 28, 2026.

In March 2026, a Los Angeles jury returned a $6 million verdict against Meta and YouTube. The plaintiff was identified only by initials — K.G.M. She had been a child when she started using Instagram and YouTube. The jury found the platforms negligent for design features that the companies' own internal research had flagged as harmful to teen girls.

It was the first individual jury award in the social media addiction litigation. School district settlements followed weeks later. The Supreme Court refused to hear Meta's jurisdictional challenge to a state attorney general suit. The companies' legal defenses are narrowing.

Over 2,500 cases are pending in MDL 3047 against Meta (Instagram, Facebook), ByteDance (TikTok), Snap (Snapchat), and Alphabet (YouTube). The next major trial — Breathitt County, Kentucky v. Meta — is set for June 12, 2026.

What the K.G.M. Verdict Means

On March 25, 2026, a Los Angeles Superior Court jury awarded $6 million to K.G.M. — $3 million in compensatory damages and $3 million in punitive damages. The jury apportioned liability 70% to Meta and 30% to Google/YouTube. The defendants were found negligent for designing platforms that harmed K.G.M.'s mental health.

Mark Zuckerberg gave his first-ever jury testimony in the case on February 18, 2026.

The verdict matters because it is the first jury determination on liability in the social media addiction litigation. Bellwether outcomes are not binding on other cases, but juries set expectations. Both Snap and TikTok had reached confidential settlements with K.G.M. ahead of trial. Neither admitted liability. Meta and YouTube went to verdict.

The damages number is not large by mass tort standards. The punitive component is. A jury awarding punitive damages — even at 1:1 ratio with compensatory — is a finding that the conduct went beyond ordinary negligence. That signal is what defendants in the remaining 2,500+ cases now have to weigh.

The Internal Documents That Surfaced

Internal company records have been central to the litigation. Several have been made public through court filings or prior reporting:

Meta's internal research. Internal research conducted by Meta (then Facebook) found that Instagram "makes body image issues worse for one in three teen girls." An internal Meta chat included the statement: "IG is a drug... we're basically pushers." These findings were first documented in the "Facebook Files" reported by The Wall Street Journal in 2021.

TikTok's internal assessment. An internal TikTok document acknowledged that "minors do not have executive mental function to control their screen time." Plaintiffs in MDL 3047 have cited this as an admission that the platform's design knowingly exploits a developmental limitation specific to children.

Engagement-over-safety priorities. Internal company data introduced in the K.G.M. trial showed that children and teenagers use these platforms at rates exceeding what the companies publicly acknowledged, and that engagement metrics — not safety metrics — drove product development decisions.

Plaintiffs allege the platforms use specific design features engineered to create compulsive use:

• Infinite scroll — removing natural stopping points
• Variable reward schedules — notifications and content delivered in slot-machine patterns
• Social comparison features — public like counts and follower metrics
• Algorithmic amplification — escalating emotionally provocative content to maintain engagement
• Autoplay — automatically queuing the next video
• Push notifications — interrupting the user to pull them back

These are not accidental features. They are the output of teams whose explicit objective was time on platform.

School District Settlements

In May 2026, Snap, YouTube (Google), and TikTok reached confidential settlements with the Breathitt County School District in Kentucky just weeks before the first MDL 3047 school district trial. Meta declined to settle and is scheduled to face the school district at trial beginning June 12, 2026.

School district claims are a distinct plaintiff category in MDL 3047. Districts are seeking to recover costs they have incurred addressing a student mental health crisis they attribute to platform design — hiring counselors, deploying mental health programs, managing classroom disruption, and processing discipline tied to social media-related conflict.

The Breathitt County settlements are confidential. Three of the four defendants chose to pay rather than face a jury that had been seated weeks after K.G.M. returned $6 million. Meta chose to fight.

The Companies Named

Meta Platforms — defendant on Instagram and Facebook claims. Found 70% liable in K.G.M. Going to trial in Breathitt County June 12, 2026.

ByteDance — defendant on TikTok claims. Settled with K.G.M. before trial. Settled with Breathitt County in May 2026.

Snap Inc. — defendant on Snapchat claims. Settled with K.G.M. before trial. Settled with Breathitt County in May 2026.

Alphabet (Google) — defendant on YouTube claims. Found 30% liable in K.G.M. Settled with Breathitt County in May 2026.

The pattern: three of the four defendants are now settling. Meta is going to trial.

Regulatory and Legislative Response

May 2026 — Supreme Court declines Meta jurisdictional challenge. The U.S. Supreme Court declined to hear Meta's jurisdictional challenge to Vermont's attorney general lawsuit, clearing the way for state-level litigation to proceed alongside the federal MDL. The ruling removes a significant defense strategy Meta had pursued to limit where it can be sued.

State attorney general actions. Multiple states have sued the same defendants under state consumer protection statutes and deceptive trade practice laws. These cases are filed outside MDL 3047. The Vermont case is one of many.

The regulatory vacuum. Unlike pharmaceuticals, food, or consumer products, social media platforms face no pre-market safety testing in the United States. There is no FDA for digital products. The Children's Online Privacy Protection Act (COPPA) addresses data collection but does not regulate platform design. The mental health harm at the center of MDL 3047 is what the regulatory framework does not yet address.

A small number of state legislatures have begun proposing platform design regulations specifically aimed at minors. None have passed yet at the federal level.
