## FAQ
### Is San Francisco a tenant's market right now?
Yes. Q1 2026 is the most tenant-favorable environment in the city since the early 2000s — both on rent and on concessions. Even trophy assets are negotiating.

### Are AI tenants actually absorbing space?
Yes — nearly all positive net absorption in 2024-2026 is AI-driven. OpenAI, Anthropic, and a long tail of foundation-model and AI-application companies are the marginal demand.
