OpenAI CEO Sam Altman gets legal notice over criminal case while onstage at SFGATE Event

OpenAI chief Sam Altman was served legal papers in person while speaking at a packed venue in San Francisco last week.

The dramatic moment happened during the session at San Francisco’s Sydney Goldstein Theaterand paused proceedings briefly.

What actually happened?

Reports from SFGATE state that an audience member left his seat near the front, approached the stage, and declared he held a subpoena for Altman. 

The document requires appearance or evidence in a legal case. Host Manny Yekutiel stepped in, took the papers, and security removed the man as the crowd voiced disapproval.

Altman stayed seated calmly, though the San Francisco Public Defender's Office stated the next day that its investigator carried out the service, per the New York Post.

"An investigator from the San Francisco Public Defender's Office lawfully served a subpoena on Mr Altman because he is a potential witness in a pending criminal case," spokesperson Valerie Ibarra said. Previous tries reached OpenAI offices and its web system.

The pause in the event cut into the OpenAI CEO’s talk with civic leader Manny Yekutiel on subjects like economic divides, AI progress, and OpenAI content rules.

Altman also fielded questions on his October post about ChatGPT allowing adult-themed material for verified users.

The timing overlapped with Governor Gavin Newsom’s denial of minor-protection AI rules, drawing outrage from legislators and families.
