Silicon Valley has recorded its largest Series A funding total for artificial intelligence companies since Q1 2020 (primarily driven by Waymo’s $2.25B round of Series A funding), reaching $2.59B in Q1 2026 and decisively outperforming San Francisco by 72.5%. This shift has only intensified into Q2 2026, with Silicon Valley already recording $1.16B against San Francisco's $423M.
Silicon Valley may now be entering a new era of AI startup dominance, as it is now competing at both stages of AI startup funding. The gap between San Francisco and Silicon Valley’s Pre-Seed/Seed funding has shrunk to $119M, the narrowest margin since Q2 2023. With Series A funding at historic highs and momentum for startups continuing to grow, H2 2026 may signal a lasting shift in Silicon Valley's favor as the go-to market for AI startups to lease space. It is undeniable that Silicon Valley possesses the talent pool to do so and with a close proximity to Venture Capital firms, AI companies are poised to continue their explosive growth in the market.
