# Social Media Addiction Lawsuit (MDL 3047): Who Qualifies in 2026 & How Cases Are Built

> **Quick answer.** MDL 3047 — *In re: Social Media Adolescent Addiction / Personal Injury Products Liability Litigation* — consolidates federal cases against Meta, TikTok, Snap, YouTube, and Discord before Judge Yvonne Gonzalez Rogers in the Northern District of California. Eligible plaintiffs are minors who used these platforms between ages seven and nineteen and developed documented mental-health injuries (depression, suicidal ideation, eating disorders, self-harm, completed suicide). The first bellwether trials are expected in late 2026 and 2027. A parallel state-court proceeding (JCCP 5255) in California aggregates state-law claims, and school-district plaintiffs are pursuing public-nuisance theories that would require the platforms to fund counselor staffing and mental-health infrastructure as abatement.

## Why this tort matters

Social media addiction litigation is, as of 2026, the largest adolescent mental health tort in U.S. history. Per the CDC's Youth Risk Behavior Survey, high school students reporting persistent sadness or hopelessness rose from roughly 28% in 2011 to 42% by 2021; female students seriously considering suicide nearly doubled; adolescent emergency-department visits for self-harm rose more than 50% for girls between 2009 and 2019; and pediatric hospital admissions for suicidal ideation more than doubled. The American Academy of Pediatrics, the American Academy of Child and Adolescent Psychiatry, and the Children's Hospital Association jointly declared a national emergency in child and adolescent mental health in October 2021.

The five primary defendants — Meta Platforms (Facebook and Instagram), TikTok and parent ByteDance, Snap (Snapchat), YouTube and parent Google/Alphabet, and Discord — collectively reach an estimated 95% of American adolescents monthly. Pew data: 58% of teens use TikTok daily, 50% YouTube, 37% Snapchat, 22% Instagram; average daily use for teens 13–17 exceeds 4.5 hours, with subpopulations at 7+ hours. The JPML transferred the federal cases to Judge Yvonne Gonzalez Rogers (who previously presided over Epic Games v. Apple) in October 2022; the Plaintiffs' Steering Committee includes more than 30 firms. Settlement valuations after a major plaintiff verdict typically rise 30–70%, which defines the 2026 acquisition window.

## How we got here: five inflection points

1. **September 2021** — the Wall Street Journal publishes the "Facebook Files," internal documents disclosed by former Meta product manager Frances Haugen showing Meta knew by 2018 that Instagram drove depression, body-image dissatisfaction, and suicidal ideation in teen girls. One internal deck reported 32% of teen girls said Instagram made them feel worse when they felt bad about their bodies.
2. **October 2021** — Haugen testifies before the U.S. Senate Subcommittee on Consumer Protection.
3. **2021–2022** — state AG investigations open (Rob Bonta, CA; Letitia James, NY; Maura Healey, MA; Jonathan Skrmetti, TN); in October 2023, 41 state attorneys general file a multistate complaint against Meta.
4. **May 2023** — Surgeon General Vivek Murthy issues the advisory *Social Media and Youth Mental Health* (25 pages, ~100 peer-reviewed studies and government reports), foreclosing lack-of-foreseeability defenses and naming feasible design alternatives (chronological feed defaults, time-limit defaults, age verification, reduced algorithmic amplification).
5. **October 2022** — the JPML consolidates the federal cases as MDL 3047 in N.D. Cal.

## Inside the Facebook Files

The unsealed documents show methodologically rigorous internal research (longitudinal studies, controlled feed experiments, thousands-strong samples) that identified specific harm-driving features: the Explore tab, Reels infinite-scroll, beauty filters, and the recommendation algorithm. Documents reported that 13% of teen girls who had suicidal thoughts traced them to Instagram use, and 6% of American teen Instagram users reported the same. Proposed mitigations — chronological feeds, time limits, beauty-filter restrictions — were rejected on engagement grounds, with Mark Zuckerberg identified as personally approving some decisions. The research also documented differential harm to teen girls, LGBTQ+ youth, adolescents with prior mental-health histories, and younger adolescents (11–13).

## The legal theories

- **Design defect** (the centerpiece): risk-utility analysis of variable-reinforcement notifications, infinite scroll, escalating recommendation algorithms, beauty filters. Courts have substantially rejected the defendants' "service, not product" argument.
- **Failure to warn:** the gap between internal knowledge and what terms of service and parent-facing materials disclosed.
- **Public nuisance:** hundreds of school districts seek court-supervised abatement (counselor staffing, mental-health infrastructure, design changes). The N.D. Cal. court substantially denied the motion to dismiss these counts in mid-2024.
- **State consumer-protection (UDAP)** claims, especially in JCCP 5255 under California's UCL, FAL, and CLRA.
- **Negligence per se** under California AB 2273 (Age-Appropriate Design Code Act), Utah SB 152 and SB 194, Arkansas's Social Media Safety Act, and similar statutes.

**Section 230** rulings have been substantially adverse to defendants on design-defect and failure-to-warn theories, following the Third Circuit's Anderson v. TikTok (2024). First Amendment defenses have largely failed (informed by Moody v. NetChoice and NetChoice v. Paxton), though they still shape the available remedies.

## The five defendants

- **Meta (Instagram):** largest exposure; Explore tab, Reels, beauty filters, Stories, Likes/follower counts. Strongest documentary record.
- **TikTok/ByteDance:** For You Page algorithm escalating adolescents toward eating-disorder, suicidal-ideation, and depression-affirming content; discovery extends to Chinese-based ByteDance subsidiaries; 2024 divestiture law (Protecting Americans from Foreign Adversary Controlled Applications Act) has accelerated discovery and raised successor-liability questions.
- **Snap:** Snap Streaks compulsive-use feature; ephemeral messaging plus My Eyes Only facilitating sextortion.
- **YouTube/Alphabet:** recommendation-algorithm content escalation (fitness/dieting to eating-disorder, self-harm, incel-adjacent content); has made litigation-period design changes.
- **Discord:** harmful-community servers and DM defaults allowing unsolicited adult contact with under-fourteen users.

## Qualifying injuries and the qualification framework

Qualifying injuries: major depressive disorder (most common), suicidal ideation/attempts, eating disorders (anorexia, bulimia, binge-eating), severe anxiety/panic disorder, body dysmorphic disorder (strong against Meta given beauty-filter documentation), non-suicidal self-injury, and completed suicide (wrongful death — highest valuations).

Screening criteria mirror the working bellwether-selection framework:

1. **Age:** minor during use (typically under 18; up to 21 at filing); strongest cases began use at ages 7–13.
2. **Platform use:** daily or near-daily use for at least six months; strongest cases involve 2+ hours daily across 3+ defendant platforms, with iOS Screen Time or Android Digital Wellbeing records.
3. **Injury:** licensed-clinician diagnosis with treatment records.
4. **Temporal nexus:** injury onset documented against the use period.
5. **Parental consent:** parent/guardian willing to act as next friend and participate in discovery.
6. **Statute of limitations:** state-specific verification.

## Statute of limitations

SOL is tolled during minority in most states; the clock starts at the plaintiff's eighteenth birthday, with post-minority periods of two years (e.g., Texas, Florida) to six years. Discovery-rule inflection candidates include the September 2021 Facebook Files publication, the October 2021 Haugen testimony, the May 2023 Surgeon General advisory, and the October 2023 multistate AG complaint. Wrongful-death claims run from the date of death and are essentially always timely as of 2026.

## Damages model

- **Economic:** treatment, educational remediation, lost wages, family disruption — typically $20K–$200K+ per case.
- **Non-economic:** pain and suffering, mental anguish — typically $100K–$1M+ per case.
- **Punitive:** supported by the Facebook Files record; Meta's market capitalization exceeds $1T (relevant under BMW v. Gore and State Farm v. Campbell). State damages caps affect valuation and forum selection.

## Bellwether timeline and settlement outlook

General-causation Daubert briefing concluded in 2024–2025 with the court substantially upholding plaintiffs' expert testimony. First-wave federal bellwethers are expected Q4 2026 through 2027; JCCP 5255 bellwethers in San Francisco Superior Court are scheduled from mid-2026 and may produce California verdicts first. Parallel coordinations are running in New York, Pennsylvania, Massachusetts, and Texas. Bellwether profiles include wrongful-death (completed suicide), severe eating disorder, body dysmorphic disorder (Instagram beauty filters), cross-platform major depressive disorder, and Snap Streaks compulsive use.

Expected settlement-matrix values: median MDD cases $150K–$400K; severe injuries $400K–$1.2M; wrongful death $1.5M–$4M+, with the most severe profiles over $5M. Historical precedent (tobacco's 1998 Master Settlement Agreement, opioid abatement settlements, asbestos long-tail trusts) suggests a global settlement within 12–24 months of the first major plaintiff verdict, with inventory monetization in the 2027–2029 window. Common-benefit fund deductions typically run 6–10% of recovery.

## Acquisition economics for PI firms

Channels: parent-targeted social ads (CPL $40–$120; cost-per-qualified-lead 3–5× that), connected TV in family viewing windows (Hulu, YouTube TV, Roku, Tubi), search on parent-intent queries (25–45% click-to-qualified conversion), school-newsletter and parenting-publication sponsorships, and long-horizon content marketing (6–12 months to build). Well-screened claimants convert at 30–45% from contact to signed retainer.

**Cost per signed retainer (2026):** roughly $1,500–$3,500 for the median MDD profile; $3,500–$7,000+ for severe-injury and wrongful-death profiles. Portfolio allocation guidance: 15–35% of new-acquisition spend for generalist mass-tort firms; 40–60% for technology/consumer-product specialists; viable first tort for solo practitioners.

## Special case subsets

- **Cyberbullying-aggravated cases:** platform design (notification cadence, group-formation, ephemeral messaging) treated as causally interrelated with peer harm; over-represented in early bellwether selection.
- **Sextortion and exploitation:** the highest-valuation subset; intersects with federal SESTA/FOSTA claims; Snap, Meta, and Discord internal records document awareness of facilitation pathways.
- **School-district public-nuisance trials** are expected in the late 2026–2027 window.

## Plaintiff demographics

Approximately 70% of the plaintiff pool is female (per PSC estimates), concentrated in eating-disorder, BDD, and Instagram-focused subsets. The modal age at qualifying-injury onset is roughly 15. Largest absolute filings come from California, Texas, Florida, New York, and Pennsylvania; California and New York over-index per capita.

## International context

The EU Digital Services Act and UK Online Safety Act (both in effect since 2024) and Australia's 2024 under-16 age-gating law have produced risk assessments and market-specific design changes that plaintiffs use as feasible-alternative-design evidence in MDL 3047.

## Frequently asked questions

### What is MDL 3047?

MDL 3047 is *In re: Social Media Adolescent Addiction / Personal Injury Products Liability Litigation*, pending in the Northern District of California before Judge Yvonne Gonzalez Rogers. It consolidates thousands of federal personal-injury cases against Meta (Facebook and Instagram), TikTok/ByteDance, Snap, YouTube/Google-Alphabet, and Discord brought on behalf of minors and their families. The JPML transferred the cases in October 2022; first bellwether trials are expected Q4 2026 through 2027.

### Which platforms are defendants in the social media addiction litigation?

The five primary defendants are Meta Platforms (Facebook and Instagram), TikTok and parent ByteDance, Snap (Snapchat), YouTube and parent Google/Alphabet, and Discord. Platform-specific features — Instagram's Explore tab, TikTok's For You Page, Snap's Streaks, YouTube's recommendation algorithm, Discord's server-and-DM architecture — anchor distinct liability theories.

### What are the legal theories in MDL 3047?

Design defect, failure to warn, negligence per se, state consumer-protection (UDAP) violations, and — in the school-district cases — public nuisance. The core theory holds the platforms knew from internal research (the Facebook Files and equivalent productions) that algorithmic engagement features caused mental-health harm in adolescents but deployed them anyway. The Surgeon General's May 2023 advisory has substantially foreclosed lack-of-foreseeability defenses.

### Who qualifies as a plaintiff in a social media addiction case?

Typically minors (under 21 at filing, with use between ages 7 and 19) who regularly used Facebook, Instagram, TikTok, Snapchat, YouTube, or Discord and developed a documented mental-health injury: major depressive disorder, suicidal ideation or attempts, eating disorders, severe anxiety, body dysmorphic disorder, self-harm, or completed suicide (wrongful death). Parental consent, treatment records, and screen-time documentation are required. Strongest cases: first use at ages 7–13, multi-platform heavy use, severe injuries, clear temporal nexus.

### When will bellwether trials begin?

Late 2026 and 2027 for the federal MDL. General-causation Daubert briefing concluded in 2024–2025 with plaintiffs' expert testimony substantially upheld. Parallel state-court trials in California (JCCP 5255) and New York may produce verdicts before the federal MDL.

### How is the statute of limitations handled for minor plaintiffs?

Most states toll the SOL during minority; the clock starts at age 18. Discovery-rule doctrines may extend further from inflection points like the September 2021 Facebook Files publication, the Haugen testimony, the May 2023 Surgeon General advisory, and the October 2023 multistate AG complaint. Wrongful-death claims run from the date of death and are essentially always timely as of 2026.

### What evidence is needed to build a social media addiction case?

Treatment records (diagnosis of depression, eating disorder, anxiety, or suicidal ideation), platform-usage history (account creation dates, Apple Screen Time or Android Digital Wellbeing data), parental testimony, and ideally a causation expert opinion. School, pediatric, hospitalization, and ER records are probative. Documented exposure to specific platform content (algorithm-surfaced self-harm content, eating-disorder communities, Snap Streak incidents) anchors strongly.

### How do PI firms acquire qualified social media addiction claimants?

By reaching parents of affected minors via parent-targeted social ads, connected TV on Hulu/YouTube TV/Roku, school-newsletter and parenting-publication sponsorships, content marketing, and long-tail search advertising. Pre-qualification must screen against the full bellwether criteria (age-at-use, platform combinations, diagnosis specificity, treatment records, temporal nexus, parental consent, SOL). Well-screened claimants convert at 30–45% from contact to signed retainer.

### What is the Facebook Files and why does it matter?

The corpus of internal Meta documents disclosed by Frances Haugen, first reported by the Wall Street Journal in September 2021. It shows Meta's research identified by 2018 that Instagram caused measurable depression, body-image dissatisfaction, and suicidal ideation in teen girls; identified the causal features (Explore tab, Reels infinite-scroll, beauty filters, recommendation algorithm); and shows Meta rejected mitigations (chronological feeds, time limits, beauty-filter restrictions) on engagement grounds. It is the evidentiary core of the case against Meta.

### What was in the Surgeon General's 2023 advisory?

Surgeon General Vivek Murthy's May 2023 advisory, *Social Media and Youth Mental Health*, is a 25-page document citing roughly 100 peer-reviewed studies and government reports, concluding there is insufficient evidence to deem social media safe for children and adolescents. It called for chronological feed defaults, time-limit defaults, age-verification improvements, and reduced algorithmic amplification for adolescent users — and foreclosed defendants' argument that the harms were not knowable.

### What damages are recoverable in MDL 3047?

Economic damages (treatment, educational remediation, lost wages, family disruption — typically $20K–$200K+), non-economic damages (typically $100K–$1M+, higher in severe profiles), and punitive damages where state standards are met — supported by the Facebook Files record and Meta's $1T+ market capitalization. State damages caps apply in some jurisdictions. Wrongful-death claims command the highest valuations.

### What are the school-district public-nuisance cases?

Hundreds of named school districts allege the platforms created a public nuisance impairing their educational mission: increased counselor demand, disciplinary burden, decreased academic performance from sleep and concentration impairment, and crisis-intervention costs. The remedy sought is court-supervised abatement — platform funding for counselors, mental-health infrastructure, and design changes. The court's mid-2024 denial of the motion to dismiss these counts was a significant plaintiff victory.

### What state AG actions are pending?

In October 2023, 41 state attorneys general filed a multistate complaint against Meta. California AG Rob Bonta filed a separate California complaint; New York AG Letitia James, Massachusetts AG Maura Healey, and Tennessee AG Jonathan Skrmetti have parallel proceedings. AG actions feed discovery into the private MDL, add settlement pressure, and — being bipartisan — defuse claims of political motivation.

### What is JCCP 5255?

The California Judicial Council Coordination Proceeding aggregating state-law claims against the same defendants, managed by the San Francisco Superior Court parallel to the federal MDL. California's UCL, FAL, and CLRA, a favorable jury pool, and broader discovery make it strategically significant. First JCCP 5255 bellwethers are scheduled for mid-2026 and may precede federal verdicts.

### How much should a PI firm allocate to MDL 3047?

Generalist mass-tort firms: typically 15–35% of new-acquisition spend in 2026. Technology/consumer-product specialists: 40–60%. Solo practitioners can treat it as a viable first tort given the bellwether-driven settlement framework. Across all profiles: acquire qualifying inventory before bellwether verdicts — the 30–70% post-verdict valuation lift accrues to firms holding inventory at verdict time.
