The wealth transfer is a rate, and the rate is small

Cerulli Associates projects that $124 trillion of U.S. wealth will be transferred through 2048, a figure Jim Grubman—who owns Family Wealth Consulting and wrote the books "Strangers in Paradise" and "Wealth 3.0"—thinks receives more deference than it deserves. "It's much less dramatic than what a lot of people think," he told InvestmentNews, and the arithmetic he offers in its place is the better planning tool, not least because it describes money that is moving now.

The concept is older than most of the advisors now selling it, tracing back to 1999 research at Boston College: a study titled "Millionaires and the Millennium: New Estimates of the Forthcoming Wealth Transfer and the Prospects for a Golden Age of Philanthropy" estimated that the U.S. would transfer at least $41 trillion between 1998 and 2052 and might transfer as much as $136 trillion. That range made sense in its moment, since the technology boom of 1992 to 2000 had created a great deal of new wealth and rising longevity was pushing the handoff further out. Cerulli's $124 trillion lands inside the range those authors sketched, near its top, which means the headline the industry plans against today sits roughly where a 1999 upper bound once sat.

The objection is to the premise that the denominator is knowable, because, as Grubman put it, "Basically, it's all projections — we don't know how much money will transfer in 2040, because we don't know how much money there will be in total in 2040." A transfer estimate is a share of a future estate, and the size of that estate is the part no projection can fix in place.

What can be measured is the annual flow, which Grubman puts at $1.5 trillion to $2 trillion a year; against Federal Reserve data showing U.S. household net worth of $154.3 trillion in 2023, that works out to about 1% — "one percent is passing," as he puts it — which makes the Great Wealth Transfer a rate rather than an event, and a modest one.

The housing market offers the closest thing to a count, with inherited homes making up a record 7% of U.S. property transfers in 2025 — 340,000 properties, according to Cotality, the data firm formerly known as CoreLogic. Realtor.com counts roughly 30 million homes owned by householders aged 65 and over, and against that stock the annual inheritance of housing is a thin slice of what will eventually pass.

The August ranking of states by per-capita senior wealth gave RIAs a density map of where senior wealth sits, while the trillion-dollar totals still favored the largest states — the mismatch you would expect when a stock is measured at the state level and a flow is felt household by household.

Scale built for the stock is scale built for a pool that will not exist until the advisors now being hired to serve it are themselves nearing retirement, and the practical cost of that strategy is that it justifies hiring, product builds, and acquisitions against capacity current revenue cannot fill. What funds a wealth management business is the annual flow and the relationships attached to it, which means the operators who win the transfer will be the ones who treat it as a retention problem, priced household by household.

Anything that holds a household through the event is therefore the product — estate and trust coordination, heir onboarding, the unglamorous mechanics of retitling accounts after a death — and Our reporting on the succession market makes the case from the other direction: Carson's purchase of a Wauwatosa practice turned on eight interviews and a three-person handoff, details that say more about the retirement wave than the $145 million book did.

Where the assets sit matters too, and here the transfer argument meets the private-markets build-out, since the on-ramp is now the product and the wrappers, feeder structures, and model-portfolio sleeves now being assembled are commonly justified by the size of the coming transfer. The flow rate is the tougher test of that thesis: a gateway whose economics depend on the pool growing is making a different bet than one that depends on converting assets the firm already manages, and only the second bet survives if the annual transfer simply tracks household net worth.

The receiving end is where projections have done the most damage to expectations, and Our reporting on family offices piling into private equity before finishing their succession work described a gap that no transfer estimate closes. Grubman's least dramatic claim may be his most useful: asked whether the pattern of inheriting has really changed, he said the answer is no. If heirs behave the way heirs always have, a larger pool does not produce a different kind of client.

Cerulli's 2048 endpoint is 22 years away, and Grubman reads the money as moving mostly in the back half of that window rather than the years immediately ahead. Firms that want to know whether they are ready for it have a test available in their own books: the share of a deceased client's household that stays, and 22 years from now, when the final projection is tallied, that will be the number that described the business.
