SF Activists to March on Anthropic, OpenAI and xAI, Demanding AI Pause

Outside Anthropic's headquarters at 500 Howard Street in San Francisco's SoMa district, activists gathered Friday for a planned peaceful march and rally targeting three of the city's most prominent artificial intelligence companies.

The demonstration, organized by a group calling itself "Stop the AI Race" and promoted by Indivisible SF, took aim at Anthropic, OpenAI, and Elon Musk's xAI with a single concrete demand: that every CEO publicly commit to pausing frontier AI development.

Organizers described the march as a response to what they characterized as the rapid, uncoordinated development of advanced artificial intelligence systems. The route covered three corporate addresses, with activists assembling first at Anthropic's 500 Howard Street location before proceeding to OpenAI and xAI.

Indivisible SF, the progressive advocacy organization that has coordinated actions ranging from beach cleanups to weekly anti-Trump demonstrations, listed the event on its actions calendar and directed supporters to RSVP through Luma. The framing on the event page was pointed: "Activists from Stop the AI Race are marching to three of the top AI Companies in SF (Anthropic, OpenAI, and xAI) to demand that every CEO must publicly commit to pausing frontier AI development."

None of the three companies had issued public responses to the demonstration's demands as of publication. The specific definition of "frontier AI" targeted by the pause demand, and any timeline organizers had in mind, were not detailed in available event materials.
