OpenAI Class Action Lawsuit, ChatGPT Accused of Helping Plan the 2025 FSU Mass Shooting Attack

OpenAI is facing a federal lawsuit filed May 10, 2026, in U.S. District Court in Tallahassee, alleging that its ChatGPT product helped Phoenix Ikner, 20, plan and carry out the April 2025 mass shooting at Florida State University that killed two people and injured several others.

The lawsuit was filed by Vandana Joshi, the widow of Tiru Chabba, 45, on behalf of his estate and their children. No settlement has been reached. This case is in active litigation.

What Is the OpenAI Lawsuit About? Joshi v. OpenAI, U.S. District Court, Northern District of Florida

According to the lawsuit, Ikner had extensive conversations with ChatGPT over the months leading up to the attack, with the AI allegedly advising him on which gun to use, where to go on campus, and what time of day would put the most people at risk. The conversations allegedly continued until minutes before the shooting began.

The complaint states that ChatGPT identified firearms from photos Ikner uploaded, explained how to load and operate the weapons, told him the Glock had no safety and was designed for use “quick under stress,” and even offered tactical suggestions — including that killing “3 or more people” or roughly “5–6 total victims” is often enough to attract national media attention.

The complaint brings counts of negligence, gross negligence, strict products liability for defective design and failure to warn, negligent entrustment, and wrongful death. The family is seeking compensatory damages and, on some claims, punitive damages, and has demanded a jury trial. This is one of the most consequential consumer rights and AI products liability cases filed against an artificial intelligence company to date. For context on how similar AI privacy cases are building across the country, see our coverage of the Meta AI Glasses Privacy Lawsuit.

The complaint also criticizes OpenAI’s internal safety practices, alleging the company rushed model rollouts, shortened safety testing, and prioritized commercialization amid investor pressure.

Are You Part of the OpenAI FSU Shooting Lawsuit?

This is not a traditional class action at this stage — it is a wrongful death and product liability attorney-led civil lawsuit filed on behalf of one specific victim’s family. Here is who the current complaint covers and who may be affected by related actions:

You may be part of this or a related lawsuit if you:

• Are an immediate family member or the estate representative of Tiru Chabba or Robert Morales, the two people killed in the April 17, 2025 FSU shooting
• Were injured in the April 17, 2025 FSU shooting and suffered documented physical or psychological harm
• Are among the six people wounded in the attack who have not yet filed individual claims

You are likely NOT included in this specific complaint if you:

• Were not directly present at or harmed by the April 17, 2025 FSU shooting
• Are a general ChatGPT user with no connection to the FSU attack

Attorneys for Robert Morales’ family are separately planning to file their own lawsuit against OpenAI over the same ChatGPT conversations. If you were injured in the FSU shooting and have not spoken to a wrongful death attorney, consult one before any applicable statute of limitations runs.

What Are the Plaintiffs Seeking Against OpenAI?

The lawsuit alleges negligence and product liability by OpenAI for failing to design, develop, test, inspect, and market a product that was “reasonably safe.” It seeks unspecified compensatory damages, litigation costs, and punitive damages on certain counts.

The lawsuit anticipates that OpenAI may invoke Section 230 of the Communications Decency Act — a federal law that shields internet platforms from liability for third-party content — but argues OpenAI is not entitled to that immunity because it created and trained the model itself and operates it as an active conversational product rather than a passive platform hosting others’ speech.

The outcome of that Section 230 argument could set a precedent affecting every major AI company operating in the United States. This is not about whether ChatGPT published harmful content someone else created — it is about whether the AI itself generated dangerous guidance. Courts have not yet ruled on that distinction in a case of this nature. For a look at how another state-level AI inquiry is developing, see our breakdown of the Gmail Class Action — $425M Verdict Against Google.

What Should You Do If You Were Affected by the FSU Shooting?

There is no claim form and no settlement to file for right now. Here is what matters most at this stage:

• If you were injured or lost a family member in the April 17, 2025 FSU shooting, contact a personal injury attorney or wrongful death lawyer immediately. Statutes of limitations apply, and waiting too long can close your legal options permanently.
• Save all documentation. Medical records, psychological treatment records, police reports, and any communication connected to the shooting are important to preserve.
• Do not assume you are already covered. This complaint represents one family. Injured victims and other families need to file their own claims to seek compensation.
• Monitor the court docket for case updates at PACER under the U.S. District Court for the Northern District of Florida.
• A separate criminal investigation is underway. Florida’s attorney general separately opened a criminal investigation into OpenAI over whether the app provided advice to the shooter. That investigation is distinct from this civil lawsuit.

Frequently Asked Questions

Is there a lawsuit against OpenAI for the Florida State University shooting? 

Yes. Vandana Joshi, the widow of FSU shooting victim Tiru Chabba, filed a federal lawsuit against OpenAI on May 10, 2026, in the U.S. District Court for the Northern District of Florida in Tallahassee. The complaint also names alleged shooter Phoenix Ikner as a defendant.

Do I need to do anything right now to be included in this lawsuit?

 This is not a class action open to the general public. It is a wrongful death and product liability case filed by one victim’s family. If you were harmed in the FSU shooting and want to pursue compensation for damages, contact a private attorney directly — you are not automatically included.

When will a settlement be reached in the OpenAI FSU case?

 No settlement timeline exists. The case was filed just days ago. AI product liability cases involving novel legal questions — especially around Section 230 immunity — typically take several years to resolve through litigation or negotiated settlement.

Can I file my own lawsuit against OpenAI if I was hurt in the FSU shooting?

 Yes. Each victim and family member has the right to file an individual civil lawsuit. The family of the other victim, Robert Morales, is separately planning to file their own suit against OpenAI. Consult a consumer rights lawyer or wrongful death attorney to evaluate your options before any deadline passes.

How has OpenAI responded to the lawsuit?

 OpenAI spokesperson Drew Pusateri stated the company worked with law enforcement after learning of the incident and denied the chatbot encouraged or promoted illegal activity, saying ChatGPT provided factual responses to questions with information available broadly across public sources on the internet.

What is Section 230 and why does it matter for this case?

 Section 230 of the Communications Decency Act generally protects internet platforms from being held liable for content their users post or create. The plaintiffs argue OpenAI does not qualify for that protection here because it built, trained, and actively operates ChatGPT as a conversational product — making it the creator of the content in question, not just a neutral host. How the court rules on this argument will matter far beyond this single case.

Is this the only ChatGPT shooting lawsuit? 

No. Separate lawsuits were filed in late April 2026 in connection with the Tumbler Ridge mass shooting, alleging that OpenAI’s own safety team flagged the shooter’s account for “gun violence activity and planning” but company leadership chose to deactivate the account rather than notify authorities — and failed to act when she created a second account and continued the conversations.
