- San Francisco–area startups raised $111.7B through Q3 2025, already beating the prior full-year record of $92.9B set in 2021.
- The broader Bay Area raised about $141.4B through Q3, putting the region on track for another annual funding record.
- In Q3 alone, the SF metro raised $27.5B and captured more than one-third of all US venture dollars.
- The surge is largely AI-driven and is further concentrating capital in San Francisco despite higher costs and growing dependence on mega-rounds.

The startup funding landscape in San Francisco (metro area including Oakland and Fremont) through the first nine months of 2025 shows a dramatic acceleration: $111.7 billion raised, exceeding any previous full-year total, including the $92.9 billion in 2021. This reflects not just large AI‐sector megadeals, but a re-consolidation of venture capital in established tech hubs.
The Bay Area at large (which includes San Jose and other Silicon Valley locales) raised an even larger figure: approximately $141.4 billion through Q3 2025, indicating that the region remains the primary destination for VC dollars in the US. In Q3 2025, Bay Area deals totaled ~$44 billion, representing around 54–57% of all US VC capital deployed that quarter. For the San Francisco area specifically, the Q3 tally of $27.5 billion was more than triple the amount raised in the same period in 2024 and made up more than one-third of US venture capital in Q3.
These trends underscore AI’s outsized influence. San Francisco’s strength derives not just from large rounds, but from its status as a talent magnet and AI ecosystem hub. As one researcher noted, “Everything AI is running through San Francisco.” While many firms outside the Bay Area struggle to raise new capital, investors and accelerators in the region actively encourage companies to base themselves in San Francisco to access capital, talent, and networks.
Yet, this concentration raises strategic concerns: saturation of real estate, increased burn requirements for AI firms, potential infrastructure and regulatory bottlenecks, and risk of valuation corrections or overdependency on a narrow set of sectors or firms. Also, the strong performance may obscure challenges for early-stage and seed funding, which lag behind in growth relative to late-stage and mega-rounds.
Open questions include whether the Bay Area can sustain this pace absent a broader ecosystem of exit opportunities (IPOs or large acquisitions), how cost of living and operational expenses will impact startups’ ability to scale, and whether emerging hubs will close the gap or whether capital will continue to flow unevenly.
Supporting Notes
- $111.7 billion raised through the first three quarters of 2025 by startups in the San Francisco metropolitan area, exceeding 2021’s full-year record of $92.9 billion.
- In Q3 alone SF-area startups raised $27.5 billion—more than triple Q3 2024—and this made up more than one-third of all US VC dollars in that quarter.
- The Bay Area (including San Jose) raised $141.4 billion through Q3 2025—a figure that would break the previous annual record of $121.9 billion.
- VC firms in the Bay Area raised $9.2 billion in new capital in Q3 2025, roughly 48% of all capital raised nationwide by VC firms in that period.
- US-wide startup funding in H1 2025 rose ~75.6% YoY to $162.8 billion, driven largely by AI; but VC fundraising (i.e. funds raising capital) dropped roughly 33.7% YoY.
- Global VC investment in Q3 2025 was ~$120.7 billion, with the Americas leading at ~$85.1 billion; big gains came from AI-driven deals.
