Evidence since 2020 supports the claim that many U.S. tech companies have reduced their concentration in San Francisco and expanded across a broader set of U.S. regions.

1. Companies reducing SF footprint and decentralizing

• A 2021 analysis by sf.citi (a San Francisco tech industry group) documented a significant migration of tech companies and workers out of San Francisco, finding that most surveyed tech companies had already downsized or planned to downsize Bay Area offices, and many expected a substantial share of their Bay Area workforce to remain permanently remote. The report explicitly described an ongoing tech exodus and a trend toward decentralization of the industry footprint away from San Francisco. (sfciti.org)
• A related sf.citi event report in March 2021 noted that the Bay Area’s dominance as the single main tech cluster was already weakening before COVID, and that the pandemic accelerated a shift toward more distributed or hub‑and‑spoke office footprints, with more tech offices in more U.S. cities (e.g., founders planning multiple hubs rather than a single SF HQ).

2. Headquarters moves and major expansions out of California/Bay Area

• Brookings (2022) highlighted that several major tech firms moved corporate headquarters from California to other metros during the pandemic period, including Palantir to Denver, Hewlett Packard Enterprise to the Houston area, Oracle and Tesla to Texas, and noted large new Google and Apple engineering offices in other states. (brookings.edu)
• A 2025 Business Insider report found that since 2020 more than 200 companies have relocated their headquarters to Texas, with over half coming from California. It specifically lists high‑profile tech and tech‑adjacent moves such as Tesla, Oracle, SpaceX, and Coinbase choosing Texas for headquarters or major bases, reflecting a sustained post‑2020 relocation trend away from California’s traditional hubs.

3. Growth of new and expanding tech hubs across the U.S.

• Brookings’ geographic analysis of the tech sector concludes that while pre‑pandemic growth was highly concentrated in a few coastal superstars (including San Francisco and San Jose), the pandemic years began to distribute more tech activity into a wider set of places. Employment growth slowed in some top superstars and increased in numerous midsized and smaller markets, suggesting a partial shift from extreme concentration toward a more geographically dispersed pattern. (brookings.edu)
• A 2022 Fortune analysis of tech job data found that, although California and New York still led in total tech employment, the fastest tech job growth during the pandemic occurred in a wide range of other states (such as Tennessee, Idaho, Utah, North Carolina, Texas) and in cities like Houston, Orlando, and Charlotte, showing that tech employment growth was increasingly scattered across the country rather than confined to the Bay Area and a few coastal hubs. (fortune.com)
• A 2025 employment intelligence report described Austin, Miami, Denver, and Nashville as major emerging tech employment centers, collectively adding 127,000 tech jobs in 2024 and growing nearly 90 percent faster than traditional hubs. It notes major firms such as Tesla, Apple, Google, and Meta building significant engineering operations in these emerging markets, along with a sharp rise in venture capital investment in nontraditional hubs, emphasizing conscious geographic diversification by companies and investors.

4. Overall assessment relative to the prediction

• Sacks’s prediction did not say San Francisco would cease to matter; it claimed that, because of SF’s policies and broader conditions after 2020, tech companies would increasingly be located all over the U.S. rather than being so heavily concentrated in the Bay Area.
• The post‑2020 evidence shows: (a) a documented reduction in SF’s share of offices and workers as many firms go remote‑first or downsize there, (b) multiple headline firms relocating headquarters or substantial operations from California to other states, and (c) rapid growth and deepening tech ecosystems in a broad range of U.S. metros (Austin, Miami, Denver, Nashville, Houston, smaller interior cities), all while SF remains important but less uniquely dominant.

Taken together, these trends match the direction and essence of the prediction: in the years after 2020, U.S. tech employment, investment, and corporate footprints have become more geographically dispersed across many regions of the country, with significant growth and relocation outside San Francisco and the Bay Area. Therefore, the prediction is best characterized as right.
