Meta Platforms, the parent company of Facebook, Instagram, and WhatsApp, has gone on trial in Tennessee over allegations that Instagram was intentionally designed with features that encourage compulsive use among teenagers.

The lawsuit, filed by Tennessee Attorney General Jonathan Skrmetti under the state’s consumer protection law, accuses Meta of misleading consumers about Instagram’s safety and concealing internal research on the platform’s potential effects on young users. Meta denies the allegations, maintaining that it has invested heavily in safety tools and that adolescent mental health is influenced by many factors beyond social media.

The case is one of several legal challenges across the United States examining whether social media companies should be held legally responsible for the design of their platforms.

Why Is Meta on Trial in Tennessee?

The lawsuit, brought by the Tennessee Attorney General, alleges that Meta violated the state’s consumer protection law by designing Instagram with features that encourage excessive engagement among young users.

According to the complaint, Meta:

• Failed to disclose internal research regarding potential risks to teenagers.
• Misled users and parents about Instagram’s safety.
• Continued using platform features despite allegedly knowing they could encourage compulsive use.

The state characterizes Instagram as an “addiction machine,” arguing that its design prioritizes user engagement over the well-being of young people.

These are allegations made by the plaintiffs. The court has not reached a final decision on the merits of the case.

What Is Meta’s Response?

Meta rejects the allegations.

The company has previously stated that its algorithms are not designed to intentionally make teenagers addicted and says it has introduced numerous tools aimed at improving safety for younger users.

Meta has argued that:

• Teen mental health is a complex issue influenced by multiple factors.
• No single social media platform can be held solely responsible for mental health outcomes.
• It continues to develop parental controls, content restrictions, and age-appropriate safety features.

The company has indicated it intends to vigorously defend itself during the trial.

Which Instagram Features Are Being Questioned?

Although the Tennessee lawsuit is broader than any single feature, similar lawsuits against Meta have focused on engagement-driven design elements such as:

• Infinite scrolling.
• Algorithmic content recommendations.
• Autoplay videos.
• Personalized content feeds.
• Push notifications.
• Variable reward systems that encourage repeated checking of the app.

Critics argue these features can encourage prolonged use, particularly among adolescents.

Meta disputes that these features are designed to create addiction.

Why Does This Case Matter?

The Tennessee lawsuit is part of a growing national debate over whether social media platforms should be legally accountable for product designs that allegedly contribute to compulsive use among minors.

If courts conclude that certain design choices violate consumer protection laws, technology companies could face:

• Financial penalties.
• Mandatory design changes.
• Additional transparency requirements.
• Increased regulatory oversight.

The outcome could influence future litigation involving digital platforms across the United States.

Other Legal Challenges Facing Meta

The Tennessee case is one of several lawsuits involving Meta’s social media platforms.

Kentucky School District Settlement

Earlier this year, Meta reached a $9 million settlement with the Breathitt County School District in Kentucky.

The district had alleged that Instagram and Facebook contributed to student mental health problems through addictive platform design. Meta settled the case without admitting wrongdoing.

California Jury Verdict

In March 2026, a California jury in K.G.M. v. Meta Platforms, Inc. et al. found Meta and Google liable on claims related to the negligent design of Instagram and YouTube.

The plaintiff alleged that prolonged use of the platforms contributed to severe mental health challenges, including depression, anxiety, eating disorders, and self-harm.

The jury awarded $6 million in damages, assigning 70% of the liability to Meta and 30% to Google.

Meta has appealed the verdict and continues to dispute the findings.

New Mexico Consumer Protection Case

Also in March, a New Mexico jury ordered Meta to pay $375 million in civil penalties after finding that the company violated the state’s consumer protection law in a case concerning representations about platform safety and child sexual exploitation risks.

Meta has appealed that judgment as well.

A Broader Wave of Social Media Litigation

Meta is not alone in facing legal scrutiny.

Meta, Google, and other technology companies are defendants in thousands of lawsuits consolidated in federal multidistrict litigation, as well as separate cases brought by:

• State attorneys general.
• School districts.
• Parents.
• Individual users.

Many of these lawsuits allege that social media companies knowingly designed products to maximize engagement among children and teenagers while failing to adequately warn users about potential risks.

Most of these claims remain contested, and many cases are still awaiting trial or appeal.

What Happens Next?

The Tennessee trial is expected to continue for six to seven weeks.

If the court ultimately finds Meta liable under Tennessee’s Consumer Protection Act, potential consequences could include:

• Civil penalties of up to $1,000 per proven violation under the statute.
• Court-ordered changes to Instagram’s design or business practices.
• Additional consumer protection remedies.

A final judgment has not yet been reached, and any decision could be subject to appeal.

The Bottom Line

The Tennessee lawsuit adds to a growing number of legal challenges examining whether social media companies should be held responsible for platform designs that allegedly encourage excessive use among young people. While Tennessee argues that Instagram was intentionally engineered to maximize engagement at the expense of teenagers’ well-being, Meta denies the allegations and says it has invested extensively in youth safety. The outcome of the case could have significant implications for consumer protection law, platform design, and the regulation of social media in the United States.

TL;DR

• A Tennessee court has begun hearing a lawsuit against Meta over Instagram’s design.
• The state alleges Meta knowingly used addictive design features targeting teenagers.
• Meta denies the allegations and says it has introduced numerous safety measures for young users.
• The trial is expected to last six to seven weeks.
• The lawsuit is part of a broader wave of litigation over social media, youth mental health, and platform design.
