A federal lawsuit filed against OpenAI alleges that ChatGPT provided detailed firearms guidance to Phoenix Ikner, the gunman behind the April 17, 2025, mass shooting at Florida State University that killed two and injured six.
The suit, brought by victim's widow Vandana Joshi, claims ChatGPT answered queries on weapon selection, attack planning, and target identification without flagging threats.
OpenAI denies the allegations, stating ChatGPT does not promote harm and relies on publicly available information.
Florida Attorney General James Uthmeier launched a criminal probe, issuing subpoenas over OpenAI's threat handling protocols.
This follows a similar Canadian lawsuit from April 2026 where seven families sued OpenAI over another mass shooting.
Market reaction in AI-focused crypto tokens has been muted with no significant price swings linked to the case.
