Supreme Court Rejects Meta’s Appeal in Vermont Instagram Algorithm Case
The Supreme Court declined to hear Meta’s appeal against Vermont’s Instagram algorithm lawsuit.
Why it matters: This decision permits state-level lawsuits challenging social media platforms’ design of addictive features, shaping legal responsibilities around youth mental health harms.
- May 26, 2026: Supreme Court declined Meta’s appeal in the Vermont case.
- Vermont AG filed the lawsuit in 2023, alleging Instagram’s algorithms harm young users’ mental health.
- Vermont Supreme Court previously upheld jurisdiction over Meta despite its challenges.
- Over 40 states have filed similar lawsuits targeting social media platforms’ youth-related harms.
On May 26, 2026, the U.S. Supreme Court declined to review Meta Platforms Inc.’s appeal regarding a lawsuit filed by Vermont’s Attorney General. The case accuses Meta of designing Instagram’s algorithms to promote addictive behaviors, particularly harming young users’ mental health.
Vermont’s lawsuit, filed in 2023, alleges Instagram’s features actively cultivate addiction and exacerbate mental health issues among children and teens. Meta challenged the court’s jurisdiction, arguing Vermont lacked authority over its platform. However, the Vermont Supreme Court rejected this claim, and the U.S. Supreme Court’s refusal to hear the appeal effectively upholds that decision.
In a statement, Vermont Attorney General Charity Clark said, “Companies that choose to do business in Vermont, like Meta, can be held accountable when they harm kids.” This underscores Vermont’s commitment to holding tech companies responsible for platform design choices affecting youth.
The Vermont case is part of a broader wave of legal actions. Over 40 states have initiated similar lawsuits against social media companies, focusing on how algorithmic content recommendations impact youth mental health. These cases collectively aim to clarify companies’ legal responsibilities for addictive features and content curation on their platforms.
Experts note that the Supreme Court’s decision not to intervene signals judicial openness to scrutinizing social media algorithms. As these lawsuits proceed, they will likely shape future legal standards on social media platform liability.

Yes, but: While the Supreme Court refused to hear the appeal, the case continues in Vermont courts where Meta may still argue other defenses, and similar lawsuits vary by state law.
What's next: The Vermont case will proceed in state courts, potentially resulting in rulings that define platform liability for engineering addictive social media features. Similar lawsuits in other states are at various stages of litigation or settlement.
