New York ranks first and San Francisco fourth in Savills’ 2026 Next Generation Wealth Hubs Index, according to Mansion Global’s report. The ranking is about how well destinations are positioned to attract and retain a particular group—not a count of recent moves—and it weighs more than a city’s technology sector.

What the ranking measures

Savills defines the next generation of wealth as people under 40 who have recently made or inherited wealth. That is a narrower group than young adults generally, all millionaires, or college graduates. The index assessed more than 100 locations, using four broad pillars: business, governance and connectivity; wealth clusters and local environment; wealth management and taxation; and lifestyle. Savills’ index summary describes those factors, but does not publish city-by-city scores or numerical weights for them.

Reported rank City
1 New York
2 Miami
3 London
4 San Francisco

Mansion Global reports this exact order. Savills’ October 2026 summary separately confirms that New York, Miami, San Francisco and Los Angeles are among the global top five, but does not provide exact positions there. The ranking therefore supports the conclusion that New York places ahead of San Francisco overall; it does not show which individual factor accounts for the gap.

Why AI wealth does not settle the comparison

San Francisco’s AI economy can be an important source of new wealth, but the index is not a contest between technology industries. Its framework also considers business conditions, governance, connectivity, established wealth clusters, local environment, wealth services, taxation and lifestyle. A strong showing in one area does not determine the combined result.

Because the available index summary gives neither pillar weights nor city scores, it cannot establish that New York beat San Francisco on any specific dimension. It also does not prove that more wealthy young people actually relocated to New York during a particular period. Savills presents the index as a comparison of destinations’ ability to attract and retain the defined cohort, not as a tally of observed moves.

How the other city figures compare

Other datasets may look similar but measure different populations and questions:

Source and year Measure Reported figure How to interpret it
Henley & Partners and New World Wealth, 2025 Resident high-net-worth individuals in New York 384,500 A resident-wealth population estimate, not the Savills destination ranking.
Henley & Partners and New World Wealth, 2025 Resident millionaires in the San Francisco Bay Area 342,400 The geography includes San Francisco and Silicon Valley; it is not San Francisco city alone.
JLL, 2025 Destination ranking for office-using U.S. graduates New York first; San Francisco second, among 1.47 million graduates analyzed A graduate and labor-market measure, not an index of wealthy people under 40.

These results are not contradictory. The wealth-population report estimates how many wealthy residents live in defined places; JLL tracks graduate destinations; Savills compares destination appeal for a specific wealth cohort. Their populations, geographic boundaries and measures differ.

What the trend could mean for cities and property

Savills frames the index against an expected transfer of US$84 trillion between generations over the next two decades, citing a Capgemini estimate in its summary. The scale of that projected transfer helps explain why cities may compete for younger wealth holders, but it does not predict how much capital will go to any particular city.

Savills World Research associate director Kelcie Sellers told Mansion Global that as wealth passes to a younger, more globally mobile and digitally connected generation, lifestyle, education, wellness and personal values are increasingly influencing where people choose to live, invest and establish businesses. Sellers also said, “Capital is likely to become more selective.” These are outlook statements, not evidence of completed property purchases or migration volumes. The index points to a broadening set of considerations for cities seeking investment and residents, without proving that any one lifestyle or real-estate factor caused New York’s lead.
