AI Accountability Lawsuits: Florida Sues OpenAI Over ChatGPT Negligence
Critics of the artificial intelligence industry have frequently raised alarms about the speed at which powerful tools are being released to the public without adequate safety testing. Now lawsuits are starting to pile up on the matters of AI negligence and AI accountability. Contact our product liability and AI Negligence Lawyers to learn more.
What Florida Is Alleging
On June 1, 2026, Florida Attorney General James Uthmeier filed an 83-page civil complaint against OpenAI and its CEO Sam Altman, alleging that the company knowingly deployed a dangerous product, suppressed internal safety warnings, and deceived millions of users, including children, about the true risks of ChatGPT.
The lawsuit was filed in Florida’s Tenth Circuit Court and carries sweeping legal implications for how AI companies may be regulated and held accountable going forward. The complaint lays out a detailed theory of corporate misconduct.
At its core, Florida argues that OpenAI prioritized market dominance and revenue growth over the safety of its users, including some of the most vulnerable populations.
According to the filing, ChatGPT generated roughly $1 billion per quarter at the end of 2024 and approximately $2 billion per month as of May 2026. The state contends that financial ambition drove OpenAI to ignore repeated warnings from experts both inside and outside the company. The specific legal claims include:
- Deceptive and unfair trade practices under the Florida Deceptive and Unfair Trade Practices Act
- Product liability, for deploying a defective and unreasonably dangerous product
- Negligence, for failing to implement adequate safeguards despite known risks
- Creating a public nuisance through ChatGPT’s alleged facilitation of harm
Critically, the suit names Sam Altman personally, arguing that he bears individual liability for decisions made at the executive level that resulted in harm to Florida residents.
The AI Negligence Allegations Involving Children
One of the most significant threads running through the complaint involves ChatGPT’s reach to minors. Florida alleges that OpenAI has collected data from children without meaningful parental consent or oversight and that the platform’s existing parental controls and age verification mechanisms are wholly inadequate. The state further claims that ChatGPT is designed in ways that cultivate behavioral addiction in young users, and that the platform causes measurable cognitive harm, including degradation of critical thinking skills.
The lawsuit also draws attention to a 16-year-old who allegedly engaged in extended conversations with ChatGPT while expressing suicidal ideation. According to the complaint, the chatbot not only failed to intervene but actively aided his death, including writing his suicide note. The filing states that ChatGPT promoted and facilitated his suicide rather than responding with any form of crisis guidance or referral.
OpenAI has responded publicly by stating that it believes minors require significant protections and that the company has implemented safety features, age-prediction tools, and parental monitoring options. The lawsuit directly contests those representations.
The FSU Shooting and the Criminal Investigation
Florida’s attorney general launched what prosecutors have described as the first-ever criminal investigation by a U.S. state targeting an AI company, stemming from the April 17, 2025 mass shooting at Florida State University.
Suspect Phoenix Ikner, then 20 years old and a student at the university, allegedly exchanged thousands of messages with ChatGPT before the attack. According to court documents reviewed in related private litigation, the chatbot provided information about weapons, discussed timing for maximum exposure on campus, and in the view of prosecutors, helped facilitate a plan that left two people dead and six injured.
The victim’s family has separately filed a lawsuit alleging wrongful death, gross negligence, products liability, and failure to warn. Their complaint argues that OpenAI built a system that perpetuated Ikner’s dangerous thinking, stayed engaged in conversations that raised clear red flags, and made no attempt to intervene or alert authorities.
The AI Accountability Legal Landscape
Florida’s filing arrives alongside more than 20 private lawsuits already pending against OpenAI over harms attributed to ChatGPT interactions. These include suits from families of the FSU victims, families of victims in a February 2026 mass shooting in Tumbler Ridge, British Columbia, and families of seven individuals who died by suicide or developed dangerous delusions after extended use of the chatbot. One of those Tumbler Ridge lawsuits alleges that OpenAI was aware the shooter had been planning the attack through ChatGPT conversations for at least eight months and took no action to alert law enforcement.
What distinguishes Florida’s suit is the deployment of the full weight of state consumer protection and product liability law, which creates the potential for systemic injunctive relief in addition to financial penalties. Attorney General Uthmeier has stated that OpenAI could face potentially billions of dollars in damages if the state prevails.
What This Means for AI Accountability
The Florida lawsuit signals a shift in how states may approach AI regulation when federal action has been slow to materialize. Product liability law, which holds manufacturers and sellers responsible for injuries caused by defective or dangerous products, has historically been used in cases involving pharmaceuticals, medical devices, and consumer goods. Applying it to AI chatbots opens an entirely new legal frontier.
If courts allow this theory to proceed, it could fundamentally change the obligations AI companies face before releasing products to the general public. Warnings, testing requirements, age verification obligations, and duty-to-warn standards that already exist in other industries could be applied to generative AI platforms, with significant consequences for the industry’s current approach to deployment.
Why The Lyon Firm Is Watching AI Negligence Cases Closely
The Lyon Firm has built its national practice on the principle that corporations cannot hide behind complexity or novelty when their products cause real harm to real people. Whether the harm comes from a defective medical device, a toxic product, or a negligently designed AI platform, the legal obligations are grounded in the same core principles: companies must know what their products do, warn users of known risks, and take reasonable steps to prevent foreseeable harm.
As AI-related litigation expands, so too does the potential for class action claims on behalf of injured users, including children and families who have suffered losses tied to AI platforms with inadequate safeguards.
