As of November 30, 2025, only about 2.5 years have passed since the April 28, 2023 prediction, and Sacks’ claim concerned a period of at least five years (into 2028) and possibly up to a decade, so it cannot yet be definitively confirmed or falsified. Current data show San Francisco’s office vacancy still extremely elevated—around 30–35% in late 2024 and early 2025, compared with pre‑pandemic “healthy” levels near 4.7–6%—so downtown has certainly not returned to a normal 5–15% vacancy range yet, which is exactly what one would expect this early in his timeline. (cresa.com) Longer‑term analyses from the city and multiple real estate research firms project that office values and vacancies may take a decade or more to get back to pre‑COVID norms, which qualitatively aligns with the spirit of his forecast but are still just projections, not outcomes. (sfchronicle.com) Because we have not yet reached the earliest point at which his prediction could be proven wrong (a sub‑15% vacancy rate before 2028), the prediction’s accuracy is still inconclusive (too early to tell).
