San Francisco's property market is experiencing unprecedented acceleration, with median prices reaching $1.76 million as of May 2026. The city reclaimed its position as America's most expensive real estate market, posting monthly gains of 14-19% since March—a dramatic departure from the 1-2% national trend. Economists attribute this surge directly to compensation windfalls concentrated among artificial intelligence sector employees, particularly from OpenAI and Anthropic, reversing the pandemic-era price softening that had briefly made San Francisco more affordable.

The underlying wealth stems from extraordinary stock arrangements at AI firms: over 600 OpenAI staff liquidated shares averaging $11 million each last October, whilst Anthropic workers recently cashed in approximately $6 billion collectively. With both companies planning public offerings within the next 1-2 years, real estate professionals expect sustained price escalation. Properties in affluent neighbourhoods like Duboce Triangle now openly accept AI company stock as payment, illustrating how concentrated employment wealth is reshaping the city's economic geography.
