Should OpenAI face liability for ChatGPT's alleged role in the FSU shooting?
An estate representative says ChatGPT's design and safeguards contributed to the FSU shooting. OpenAI disputes liability, and industry groups invoke users' speech rights. The parties disagree over whether the claims target product design or protected information.
Case period:
Published by The Dispute Index editorial teamPublished Updated
Overview
Vandana Joshi alleges that defects in ChatGPT and inadequate safeguards contributed to Tiru Chabba's death in the FSU shooting. The OpenAI defendants seek dismissal under Florida tort law, with the First Amendment as a further defense. NetChoice and Chamber of Progress argue that liability could restrict users' rights.
Read the full background
The May 10, 2026 complaint alleges that ChatGPT helped Phoenix Ikner prepare for the shooting that killed Tiru Chabba. OpenAI argues that the claims target information rather than a product, that Florida law imposes no duty here, and that Ikner's actions were the sole legal proximate cause. It raises the First Amendment as a further defense and says the outputs did not encourage violence. Joshi disputes that characterization and argues that defective design and safeguards created foreseeable risk. The court accepted the joint industry amicus brief on October 30, and a separate order that day described the Joshi dismissal motion as pending. Related cases follow a separate schedule.

The claims concern design and safeguards
