How Illinois' New Law Bans 'Addictive Algorithms' and Mandates OS-Level Age Verification for Minors

Illinois has fundamentally altered the legal landscape for tech giants, enacting a landmark law that targets the behavioral algorithms powering modern social media. On July 31, 2026, Governor JB Pritzker signed the Children's Online Social Media Safety Act into law, capping a legislative session that prioritized youth mental health and digital well-being.[1][2]

The legislation, which passed both the Illinois House and Senate with unanimous, bipartisan support, represents a strategic shift in how governments attempt to regulate the internet. Rather than attempting to censor specific types of harmful content—a tactic that routinely triggers First Amendment lawsuits—Illinois is regulating the underlying design architecture of the platforms themselves.[3][4]

At the heart of the new law is a strict prohibition on "addictive feeds" for any user under the age of 18. For the past decade, platforms have relied on sophisticated algorithms that track a user's viewing history, dwell time, and device data to serve up an endless stream of hyper-personalized content designed to maximize engagement and keep users scrolling.[1][5]

Under the new framework, which takes full effect on January 1, 2028, this behavioral tracking is banned for minors. Instead, young users will experience a vastly different internet: their feeds will be strictly limited to content they actively search for, media posted by creators they explicitly follow, and direct private messages.[1][7]

"Big tech companies understand and have confessed to how their algorithms can harm children, yet they refuse to take meaningful action on their own," Pritzker noted during the signing ceremony. "So, we are going to start by requiring real change."[2]

The most technically ambitious component of the Illinois law is its approach to age verification. Previous attempts by other states to mandate age checks faced fierce backlash from privacy advocates, who warned that forcing users to upload driver's licenses or facial recognition scans to dozens of different apps created a massive cybersecurity vulnerability.[2][5]

Illinois sidesteps this hazard by shifting the burden of verification away from individual social media companies and onto the device's operating system. The law mandates that operating system providers—primarily Apple and Google—must create an accessible interface during device setup that requires an account holder to input a birth date.[1][6]

Once the device knows the user's age, it acts as a privacy shield. When a minor opens a social media app, the operating system sends a minimal "signal" to the platform indicating only the user's age bracket. The app never receives the user's exact birthdate or underlying identification documents, yet it is legally bound to treat that OS-level signal as an authoritative mandate to lock down the account's default settings.[5][6]

Beyond the algorithmic feed ban, the legislation imposes a suite of default privacy and health protections. Recognizing the severe impact of screen time on adolescent sleep cycles, the law strictly prohibits social media platforms from sending push notifications to minors between 10 p.m. and 7 a.m. The only exception to this nighttime blackout is for direct, private messages from friends and family.[2][5]

The law also targets the physical safety and financial security of young users. Platforms are banned from sharing a minor's precise location data by default, closing a loophole that has historically allowed bad actors to track teenagers' movements.[2][5]

Additionally, the legislation blocks minors from engaging in digital currency transactions or "gifted currency" exchanges with strangers without explicit parental consent, a measure designed to curb financial exploitation and scamming on gaming and streaming platforms.[2][5]

While the default settings are strictly locked down, the law does carve out mechanisms for parental control. Parents of minors aged 16 and 17 are granted the authority to override the privacy settings if they choose, while parents of younger children can approve specific content and features on a case-by-case basis.[2][7]

Enforcement of the Children's Online Social Media Safety Act rests entirely with the Illinois Attorney General. The legislation classifies violations as unlawful practices under the state's Consumer Fraud and Deceptive Business Practices Act, granting the Attorney General subpoena power and the ability to seek steep civil penalties and injunctive relief.[6][7]

Crucially, lawmakers opted not to include a "private right of action," meaning individual citizens and class-action lawyers cannot independently sue tech companies over algorithmic violations. This concession was likely designed to prevent a flood of frivolous litigation while keeping enforcement centralized and systematic.[7]

The tech industry has generally opposed the legislation, warning that the technical requirements—particularly the OS-level age signaling—rely on standards that do not yet exist at scale. Industry groups argue that forcing device manufacturers to build and maintain these verification pipelines by 2028 will require a massive, complex overhaul of global mobile operating systems.[1]

Despite this opposition, child safety advocates view the Illinois model as a masterclass in effective tech regulation. By focusing on product liability and consumer protection rather than speech, the law is heavily insulated against the constitutional challenges that have frozen similar efforts in states like California and Arkansas.[3][4]

As the 2028 implementation deadline approaches, the tech industry faces a critical decision. Companies must either build a geofenced, compliance-heavy version of their platforms specifically for Illinois residents, or—as is often the case with strict state-level tech laws—adopt the Illinois standards as their new national baseline for minor safety.[3][7]
