Meta Pays $18B to End the Addiction Trial — and Makes 2-Hour Teen Limits the New Default

Meta has agreed to pay more than $18 billion to settle the landmark lawsuit brought by 29 U.S. attorneys general — one week into a California trial that alleged the company intentionally designed addictive systems while knowing the risks, with teenagers at the center. Facing combined damage claims that could have exceeded $1 trillion, Meta chose to stop a trial expected to run for weeks and surface more damaging internal documents.

What the settlement changes: teen defaults

Under the agreement, Meta will impose sweeping default restrictions for users under 18: a two-hour daily usage limit (parent-removable only, cumulative across all of a teen's Facebook and Instagram accounts), a default block from midnight to 6 a.m., and muted notifications during school hours (8 a.m.–3 p.m.). Teens get break prompts every 15 minutes of continuous use and alerts at 60 and 90 minutes of daily usage. They can choose a non-algorithmic feed as their default, turn off autoplay, and won't see like counts by default. Cosmetic surgery and extreme makeup filters are disabled for teens. Meta also committed to stronger under-13 detection, technology to catch 13–17-year-olds registering with adult birthdays, an independent research foundation, and independent compliance audits.

Most settings hold for 10 years; the time limits for at least five. The $18 billion pays out in annual installments over a decade, with participating states receiving about 70%. The remaining 30% — roughly $5.3 billion — is conditional: it's released only if TikTok and YouTube commit to the same daily usage restrictions and each pays a matching amount.

Why settle — and why drag competitors in

Meta's calculus runs several layers deep. The trial had already begun exposing internal decision-making that reflected poorly on its safety posture, and low public trust directly threatens the company's "personal superintelligence" ambitions — which require users to hand over more personal data, not less. Teen usage of Facebook was declining anyway, making the restrictions less costly for Meta than for rivals. Global teen-restriction regulation was coming regardless. And the settlement's structure is itself a weapon: it shifts the spotlight — and the compliance bill — onto TikTok and YouTube, whose businesses lean far harder on teen time spent.

Note the carve-out: direct messaging is excluded from Night Mode, Time Limit, and School Mode. As sharing migrates from feeds into DMs, Meta — owner of Messenger and WhatsApp — has done the math: push teens out of feeds and they land in messaging, where Meta still wins.

What marketers should take from this

Teen ad inventory shrinks structurally. Two-hour cumulative caps, overnight and school-hour blocks, and default non-algorithmic feed options all raise the cost and difficulty of teen reach. The DM exclusion cuts the other way: messaging-based marketing — keyword-triggered DMs, channels, commerce conversations — gains relative value. Brands that depend on teen audiences should be reducing feed dependency and validating messaging and creator paths now.
