Older Americans may be trading in hustling for retirement, but that hasn’t stopped them from getting richer.

Baby boomers now hold a record high of the United States’ wealth, Apollo chief economist Torsten Slok noted in a Sunday blog post, citing Federal Reserve data. Compared to 1989, when those over 70 years old held 19% of the wealth in the household sector, older Americans now own 31% of the wealth.

That chunk of change is an outsize share compared to other generations. Baby boomers, who make up about 20% of the U.S. population, hold more than $85 trillion in assets, according to Fed data. By comparison, millennials, who make up about the same percentage of Americans, hold just about $18 trillion, roughly one-fifth that of baby boomers.

Older Americans’ financial success is in especially stark comparison to that of Gen Z, a generation with deep skepticism about the economic future, who feel shut out from entry-level jobs amid the rise of AI, with many sinking into credit card debt as they struggle to repay student loans. As of last year, the young generation had only $6 trillion in wealth, despite making up the same percentage of the population as their baby boomer and millennial counterparts.
