Research note: Eight US states sue OpenAI, saying ChatGPT harmed children and that the company misled the public about its safety

What we set out to check

Which states sued, in which courts and under which laws, what they allege and ask for, and how OpenAI responded.

What we found

• Bloomberg Law and Kansas’s attorney general (via KWCH) list the same eight states.
• Arizona and Montana published their own press releases naming the laws and courts.
• OpenAI’s response comes from its spokesperson, quoted by Bloomberg Law.

Numbers that differ

Bloomberg Law’s headline says a “half dozen” states, while its text and the Kansas announcement name eight. We use eight.

Labels we chose and why

• Reported for the eight filings, carried by Bloomberg Law and the Kansas announcement.
• Confirmed for each state’s law and allegations, from official releases. We describe them as allegations because no court has ruled.
• Company claim for OpenAI’s description of its safeguards.

What we could not verify

• The full complaints and the exact relief each state seeks.
• Hearing dates.

We left out details of individual deaths described in one state’s release, to avoid repeating harmful specifics, and added a helpline note.
