LOS ANGELES (AP) — Jurors in a landmark social media case that seeks to hold tech companies responsible for harms to children got their first glimpse into what will be a lengthy trial characterized by dueling narratives from the plaintiffs and the two remaining defendants, Meta and YouTube.
At the core of the Los Angeles case is a 20-year-old identified only by the initials “KGM,” whose case could determine how thousands of similar lawsuits will play out. KGM and the cases of two other plaintiffs have been selected to be bellwether trials — essentially test cases for both sides to see how their arguments play out before a jury.
“This is a monumental inflection point in social media,” said Matthew Bergman of the Seattle-based Social Media Victims Law Center, which represents more than 1,000 plaintiffs in lawsuits against social media companies. “When we started doing this four years ago no one said we’d ever get to trial. And here we are trying our case in front of a fair and impartial jury.”
On Wednesday Meta CEO Mark Zuckerberg testified, mostly sticking to past talking points, including a lengthy back-and-forth about age verification where he said ““I don’t see why this is so complicated,” reiterating that the company’s policy restricts users under the age of 13 and that it works to detect users who have lied about their ages to bypass restrictions.
At one point, the plaintiff’s attorney, Mark Lanier, asked Zuckerberg if people tend to use something more if it’s addictive.
“I’m not sure what to say to that,” Zuckerberg said. “I don’t think that applies here.”

LOS ANGELES (AP) — Mark Zuckerberg, the CEO of Meta, will testify during a landmark social media trial in Los Angeles. The plaintiff, a now 20-year-old woman, is seeking to hold social media companies responsible for harms to children who use their platforms. Meta and YouTube are the two remaining defendants in the case, which TikTok and Snap settled. Zuckerberg’s testimony comes a week after the testimony of Adam Mosseri, the head of Meta’s Instagram. Zuckerberg is expected to face questions about Instagram’s algorithm, the infinite nature of its platforms’ feeds and other features the plaintiffs argue are designed to get users hooked.

LOS ANGELES (AP) — Comparing social media platforms to casinos and addictive drugs, lawyer Mark Lanier delivered opening statements Monday in a landmark trial in Los Angeles that seeks to hold Instagram owner Meta and Google’s YouTube responsible for harms to children who use their products.
Instagram’s parent company Meta and Google’s YouTube face claims that their platforms addict children through deliberate design choices that keep kids glued to their screens. TikTok and Snap, which were originally named in the lawsuit, settled for undisclosed sums.
Jurors got their first glimpse into what will be a lengthy trial characterized by dueling narratives from the plaintiffs and the two remaining defendants.
Meta lawyer Paul Schmidt spoke of the disagreement within the scientific community over social media addiction, with some researchers believing it doesn’t exist, or that addiction is not the most appropriate way to describe heavy social media use.
Lawyers representing YouTube will begin their opening statement on Tuesday.
‘Addicting the brains of children’
Lanier, the plaintiff’s lawyer, delivered lively first remarks where he said the case will be as “easy as ABC” — which stands for “addicting the brains of children.” He said Meta and Google, “two of the richest corporations in history,” have “engineered addiction in children’s brains.”
He presented jurors with a slew of internal emails, documents and studies conducted by Meta and YouTube, as well as YouTube’s parent company, Google. He emphasized the findings of a study Meta conducted called “Project Myst” in which they surveyed 1,000 teens and their parents about their social media use. The two major findings, Lanier said, were that Meta knew children who experienced “adverse events” like trauma and stress were particularly vulnerable for addiction; and that parental supervision and controls made little impact.
He also highlighted internal Google documents that likened some company products to a casino, and internal communication between Meta employees in which one person said Instagram is “like a drug” and they are “basically pushers.”
At the core of the Los Angeles case is a 20-year-old identified only by the initials “KGM,” whose case could determine how thousands of other, similar lawsuits against social media companies will play out. She and two other plaintiffs have been selected for bellwether trials — essentially test cases for both sides to see how their arguments play out before a jury.
Plaintiff grew up using YouTube, Instagram
KGM made a brief appearance after a break during Lanier’s statement and she will return to testify later in the trial. Lanier spent time describing KGM’s childhood, focusing particularly on what her personality was like before she began using social media. She started using YouTube at age 6 and Instagram at age 9, Lanier said. Before she graduated elementary school, she had posted 284 videos on YouTube.
The outcome of the trial could have profound effects on the companies’ businesses and how they will handle children using their platforms.
Lanier said the companies’ lawyers will “try to blame the little girl and her parents for the trap they built,” referencing the plaintiff. She was a minor when she said she became addicted to social media, which she claims had a detrimental impact on her mental health.
Lanier said that despite the public position of Meta and YouTube being that they work to protect children, their internal documents show an entirely different position, with explicit references to young children being listed as their target audiences.
The attorney also drew comparisons between the social media companies and tobacco firms, citing internal communication between Meta employees who were concerned about the company’s lack of proactive action about the potential harm their platforms can have on children and teens.
“For a teenager, social validation is survival,” Lanier said. The defendants “engineered a feature that caters to a minor’s craving for social validation,” he added, speaking about “like” buttons and similar features.
Meta pushes back
In his opening statement representing Meta, Schmidt said the core question in the case is whether the platforms were a substantial factor in KGM’s mental health struggles. He spent much of his time going through the plaintiff’s health records, emphasizing that she had experienced many difficult circumstances in her childhood, including emotional abuse, body image issues and bullying.
Schmidt presented a clip from a video deposition from one of KGM‘s mental health providers, Dr. Thomas Suberman, who said social media was “not the through-line of what I recall being her main issues,” adding that her struggles seemed to largely stem from interpersonal conflicts and relationships. He painted a picture — with KGM’s own text messages and testimony pointing to a volatile home life — of a particularly troubled relationship with her mother.
Schmidt acknowledged that many mental health professionals do believe social media addiction can exist, but said three of KGM’s providers — all of whom believe in the form of addiction — have never diagnosed her with it, or treated her for it.
Schmidt emphasized to the jurors that the case is not about whether social media is a good thing or whether teens spend too much time on their phones or whether the jurors like or dislike Meta, but whether social media was a substantial factor in KGM’s mental health struggles.
A reckoning for social media and youth harms
A slew of trials beginning this year seek to hold social media companies responsible for harming children’s mental well-being. Executives, including Meta CEO Mark Zuckerberg, are expected to testify at the Los Angeles trial, which will last six to eight weeks. Experts have drawn similarities to the Big Tobacco trials that led to a 1998 settlement requiring cigarette companies to pay billions in health care costs and restrict marketing targeting minors.
A separate trial in New Mexico, meanwhile, also kicked off with opening statements on Monday. In that trial, Meta is accused of failing to protect young users from sexual exploitation, following an undercover online investigation. Attorney General Raúl Torrez in late 2023 sued Meta and Zuckerberg, who was later dropped from the suit.
A federal bellwether trial beginning in June in Oakland, California, will be the first to represent school districts that have sued social media platforms over harms to children.
In addition, more than 40 state attorneys general have filed lawsuits against Meta, claiming it is harming young people and contributing to the youth mental health crisis by deliberately designing features on Instagram and Facebook that addict children to its platforms. The majority of cases filed their lawsuits in federal court, but some sued in their respective states.
TikTok also faces similar lawsuits in more than a dozen states.

LOS ANGELES (AP) — The world’s biggest social media companies face several landmark trials this year that seek to hold them responsible for harms to children who use their platforms. Opening arguments for the first, in Los Angeles County Superior Court, begin this week. Instagram parent company Meta and Google’s YouTube will face claims that their platforms deliberately addict and harm children. TikTok and Snap, which were originally named in the lawsuit, settled for undisclosed sums. This case marks the first time the companies will argue their case before a jury, and the outcome could have profound effects on their businesses and how they will handle children using their platforms.
Jan. 27, 2026, update:
LOS ANGELES (AP) — TikTok agreed to settle a landmark social media addiction lawsuit just before the trial kicked off, the plaintiff’s attorneys confirmed.
The social video platform was one of three companies — along with Meta’s Instagram and Google’s YouTube — facing claims that their platforms deliberately addict and harm children. A fourth company named in the lawsuit, Snapchat parent company Snap Inc., settled the case last week for an undisclosed sum.
Details of the settlement with TikTok were not disclosed, and the company did not immediately respond to a request for comment.
At the core of the case is a 19-year-old identified only by the initials “KGM,” whose case could determine how thousands of other, similar lawsuits against social media companies will play out. She and two other plaintiffs have been selected for bellwether trials — essentially test cases for both sides to see how their arguments play out before a jury and what damages, if any, may be awarded, said Clay Calvert, a nonresident senior fellow of technology policy studies at the American Enterprise Institute.
Joseph VanZandt, co-lead counsel for the plaintiff, said in a statement Tuesday (Jan. 27, 2026) that TikTok remains a defendant in the other personal injury cases, and that the trial will proceed as scheduled against Meta and YouTube.
Jury selection starts this week in the Los Angeles County Superior Court. It’s the first time the companies will argue their case before a jury, and the outcome could have profound effects on their businesses and how they will handle children using their platforms. The selection process is expected to take at least a few days, with 75 potential jurors questioned each day through at least Thursday. A fourth company named in the lawsuit, Snapchat parent company Snap Inc., settled the case last week for an undisclosed sum.
“This was only the first case — there are hundreds of parents and school districts in the social media addiction trials that start today, and sadly, new families every day who are speaking out and bringing Big Tech to court for its deliberately harmful products,” said Sacha Haworth, executive director of the nonprofit Tech Oversight Project.
KGM claims that her use of social media from an early age addicted her to the technology and exacerbated depression and suicidal thoughts. Importantly, the lawsuit claims that this was done through deliberate design choices made by companies that sought to make their platforms more addictive to children to boost profits. This argument, if successful, could sidestep the companies’ First Amendment shield and Section 230, which protects tech companies from liability for material posted on their platforms.
“Borrowing heavily from the behavioral and neurobiological techniques used by slot machines and exploited by the cigarette industry, Defendants deliberately embedded in their products an array of design features aimed at maximizing youth engagement to drive advertising revenue,” the lawsuit says.
Executives, including Meta CEO Mark Zuckerberg, are expected to testify at the trial, which will last six to eight weeks. Experts have drawn similarities to the Big Tobacco trials that led to a 1998 settlement requiring cigarette companies to pay billions in health care costs and restrict marketing targeting minors.
“Plaintiffs are not merely the collateral damage of Defendants’ products,” the lawsuit says. “They are the direct victims of the intentional product design choices made by each Defendant. They are the intended targets of the harmful features that pushed them into self-destructive feedback loops.”
The tech companies dispute the claims that their products deliberately harm children, citing a bevy of safeguards they have added over the years and arguing that they are not liable for content posted on their sites by third parties.
“Recently, a number of lawsuits have attempted to place the blame for teen mental health struggles squarely on social media companies,” Meta said in a recent blog post. “But this oversimplifies a serious issue. Clinicians and researchers find that mental health is a deeply complex and multifaceted issue, and trends regarding teens’ well-being aren’t clear-cut or universal. Narrowing the challenges faced by teens to a single factor ignores the scientific research and the many stressors impacting young people today, like academic pressure, school safety, socio-economic challenges and substance abuse.”
A Meta spokesperson said in a statement Monday the company strongly disagrees with the allegations outlined in the lawsuit and that it’s “confident the evidence will show our longstanding commitment to supporting young people.”
José Castañeda, a Google Spokesperson, said Monday that the allegations against YouTube are “simply not true.” In a statement, he said “Providing young people with a safer, healthier experience has always been core to our work.”
TikTok did not immediately respond to a request for comment Monday.
The case will be the first in a slew of cases beginning this year that seek to hold social media companies responsible for harming children’s mental well-being.

The majority of cases filed their lawsuits in federal court, but some sued in their respective states.
TikTok also faces similar lawsuits in more than a dozen states.
In New Mexico, meanwhile, jury selection begins next week for trial on allegations that Meta and its social media platforms have failed to protect young users from sexual exploitation, following an undercover online investigation. Attorney General Raúl Torrez in late 2023 sued Meta and Zuckerberg, who was later dropped from the suit.
Prosecutors have said that New Mexico is not seeking to hold Meta accountable for its content but rather its role in pushing out that content through complex algorithms that proliferate material that can be harmful, saying they uncovered internal documents in which Meta employees estimate about 100,000 children every day are subjected to sexual harassment on the company’s platforms.
Meta has said it uses sophisticated technology, hires child safety experts, reports content to the National Center for Missing and Exploited Children, and shares information and tools with other companies and law enforcement, including state attorneys general, to help root out predators.
