TECHNOLOGY & BUSINESS — A major legal battle involving Meta, the parent company of Facebook and Instagram, has begun in California, with a coalition of U.S. states accusing the company of designing its platforms in ways that harmed young users.

The case could have significant consequences for how Facebook and Instagram operate if the states succeed in proving their allegations. The trial began in federal court in Oakland on August 18, 2026, and is expected to continue for several weeks. 0

The case is being closely watched because it combines allegations involving youth mental health, platform design, consumer protection and children's privacy.

Twenty-Nine States Are Taking on Meta

A bipartisan coalition of 29 U.S. states is pursuing the case, with California, Colorado, Kentucky and New Jersey leading the effort.

The states allege that Meta deliberately designed Facebook and Instagram to encourage excessive use among children and teenagers.

They also accuse the company of misleading the public about the safety of its platforms and improperly collecting and using personal information belonging to children.

Meta strongly disputes the allegations.

The Case Is Focused on Young Users

A central issue in the trial is whether Meta's platform design contributed to harmful outcomes for young people.

Prosecutors are expected to examine features including infinite scrolling, notifications, recommendation systems and other mechanisms that can encourage users to remain on the platforms for longer periods.

The states argue that Meta knew about concerns surrounding young users but failed to adequately address them.

Meta argues that it has invested heavily in safety measures and that the states have not established the necessary evidence of wrongdoing or actual harm.

Children's Privacy Is Another Major Issue

The case also involves allegations that Meta improperly collected and used information from children under federal privacy laws.

Protecting children's personal information has become an increasingly important issue as younger users gain access to social media platforms.

The states argue that Meta's practices did not adequately protect children from data collection and other risks.

The company disputes the accusations and maintains that it has developed protections for younger users.

The Trial Could Force Changes to Facebook and Instagram

The consequences could extend beyond financial penalties.

California, Colorado, Kentucky and New Jersey are asking the court to require changes to the way Meta operates its platforms, including measures involving age restrictions and the use of infinite scrolling.

If such measures were imposed broadly, they could affect how millions of people interact with Facebook and Instagram.

They could also influence how other social media companies design products aimed at younger audiences.

Meta Says the Claims Are Unsubstantiated

Meta has rejected the states' allegations.

The company argues that it has taken significant steps to protect teenagers and improve safety across its platforms.

Meta also argues that some of the features being criticised are common across the technology industry and that the states have not demonstrated that the company violated the law.

The company's defence will be closely examined during the trial.

Mark Zuckerberg Could Testify

Meta founder and chief executive Mark Zuckerberg is expected to testify during the trial, along with Instagram chief Adam Mosseri.

Their testimony could provide insight into how Meta's leadership viewed the risks associated with young users and how the company made decisions about platform design.

Internal company communications and research are also expected to play an important role in the proceedings.

The Jury Has an Unusual Role

An eight-person jury is participating in the trial in an advisory capacity.

U.S. District Judge Yvonne Gonzalez Rogers will ultimately decide whether Meta is legally liable.

This makes the proceedings different from a conventional jury trial in which the jury directly delivers the final verdict.

The Potential Financial Stakes Are Enormous

The financial consequences could be substantial.

Meta has said the states' claims could expose the company to potential penalties as high as $1.4 trillion, although the attorneys general have indicated that their eventual demands could be closer to $200 billion.

Such figures demonstrate why the case is being treated as one of the most important legal challenges Meta has faced over the operation of its social media platforms.

This Is Part of a Much Bigger Legal Battle

The California trial is not an isolated dispute.

Meta and other major technology companies are facing numerous lawsuits across the United States involving allegations that social media platforms can contribute to problems affecting children and teenagers.

Other cases have already produced significant legal setbacks for Meta, increasing attention on the California proceedings.

The outcome could therefore influence future lawsuits and regulatory action against social media companies.

Why the Case Matters Beyond Meta

If the states establish that certain platform designs violate consumer protection or privacy laws, other technology companies could face pressure to change similar features.

That could affect the wider social media industry.

Companies may become more cautious about designing features that maximise engagement among younger users, particularly if courts determine that certain practices create unacceptable risks.

The Bigger Question: Who Is Responsible for Online Harm?

The case raises a difficult question about responsibility in the digital age.

Social media platforms are designed to attract and retain users, but governments and parents increasingly want stronger safeguards for children.

The challenge is determining where legitimate product design ends and harmful manipulation begins.

The court's eventual decision could help define that boundary.

What Could Happen to Facebook and Instagram?

A ruling against Meta could lead to changes in areas such as age verification, recommendation systems, notifications, scrolling features and the treatment of younger users.

A major financial penalty could also increase pressure on Meta to change its business practices.

However, the company is expected to defend itself aggressively, and any significant ruling could face further legal challenges.

Our Perspective

This case should not be reduced to a simple argument that social media is either good or bad.

The more important question is whether companies should be legally responsible when evidence shows that particular product decisions create foreseeable risks for children.

At the same time, regulators must avoid imposing rules based solely on political pressure or assumptions about technology.

The strongest outcome would be one based on evidence: identifying which platform practices genuinely cause harm, which protections actually work and what responsibilities technology companies should legally carry.

Conclusion

The landmark Meta trial underway in California could become one of the most consequential legal battles involving social media and young people.

A coalition of 29 states is accusing Meta of designing Facebook and Instagram to encourage addictive use among children and teenagers, misleading the public about safety and improperly handling children's personal data. 4

Meta denies the allegations and says it has taken substantial steps to protect young users.

The case could ultimately determine whether Meta must make significant changes to the way Facebook and Instagram operate.

Whatever the final outcome, the trial is likely to influence the future of social media regulation and the responsibilities technology companies have toward their youngest users.
