About 200 protesters marched through San Francisco on Saturday, tracing a route from OpenAI’s headquarters straight through to the offices of Anthropic and Google DeepMind. The message was blunt: stop training more powerful AI models until someone figures out what they’re actually doing to society.

The demonstration, organized by a group called Stop the AI Race, marks the second time the same coalition has taken to the streets in 2026. A similar march happened in March, targeting the same companies with the same core demands.

What the protesters actually want

The signs and chants centered on three grievances: AI safety, job displacement, and environmental damage from the energy-hungry data centers powering frontier models.

Organizers called directly on executives at OpenAI, Anthropic, and Google DeepMind to pause the training of new, more capable AI systems.
