A San Francisco Superior Court jury has convicted a woman who prosecutors said helped chain shut the entrance to OpenAI’s headquarters during a protest last year.
Wynd Sethe Kaufmyn, 68, was found guilty after a trial of interfering with a business, trespassing with the intent to interfere with a business, unlawful assembly, and refusing to disperse during a riot, the San Francisco District Attorney’s Office said.
The case stemmed from a Feb. 22, 2025, protest by members of the group STOP AI outside OpenAI’s offices on Third Street in San Francisco. According to trial evidence, protesters placed a chain across the building’s front door and secured it with a padlock before sitting in front of the entrance. OpenAI employees called 911, prompting a response from the police.
Prosecutors said officers told the demonstrators they were on private property and could continue protesting if they moved a short distance to the public sidewalk. The protesters, including Kaufmyn, refused to move and were cited. Officers later cut the chain from the door.
Kaufmyn is not in custody and is scheduled to be sentenced on June 22, according to prosecutors.
The conviction comes amid continuing public debate over artificial intelligence and the tactics used by some activists seeking tighter regulation of the technology.
