The demographics behind the private business economy are shifting, and the effect will be felt one company at a time. Somewhere between 2.3 and 3 million businesses owned by retiring baby boomers are expected to change hands over the next decade, a transition large enough that advisors have taken to calling it the silver tsunami. For an individual owner, the headline number matters less than a quieter fact underneath it: more companies will reach the market at the same time, and buyers have become choosier about which ones they pursue.
The scale is easy to understate. The businesses in question employ roughly 32 million people and generate close to $6.5 trillion in annual revenue, so this is not a niche corner of the economy but a meaningful share of it. Cerulli Associates estimates that around $18 trillion of wealth currently sits inside privately held businesses, part of a broader $124 trillion that will pass from boomer households to heirs and charity through 2048. Much of that business value can only be realized through a sale or an internal transfer, which is what turns a demographic trend into a wave of transactions.
The timing is compressed because ownership and age move together. Many of these companies were founded or acquired in the 1980s and 1990s, and their owners are now reaching the point where retirement is a decision rather than a someday. The result is a growing supply of sellers arriving over a relatively short window, rather than the steady trickle the market is used to absorbing.
Rising supply would not matter much if buyers were indifferent to which company they bought. They are not. The 2026 deal market has been defined by selectivity: buyers are examining fewer companies more closely, and the findings of that scrutiny can move a purchase price by a wide margin. First-half data showed financial buyers concentrating capital in fewer, larger transactions, while strategic corporate acquirers grew more active. Neither group is short of capital. Both are disciplined about where it goes.
That discipline shows up most clearly in valuation. Middle-market businesses have continued to sell at purchase prices around 7 to 7.5 times EBITDA (earnings before interest, taxes, depreciation, and amortization, a common proxy for operating cash flow), and that headline multiple has held roughly steady. The average hides a wide spread, though. Companies with recurring or contracted revenue command premiums of one and a half to two and a half turns of EBITDA over comparable project-based businesses, and quality factors such as customer diversification and management depth can separate otherwise similar companies by several turns. In a crowded market, being average is not a neutral position. It is a discount.
The gap between the companies that sell well and the ones that do not is largely a gap in preparation, and the numbers are sobering. Only about half of retiring owners have a formal succession or exit plan in place. Roughly 70 percent of businesses put on the market never sell at all, often because problems surface in diligence that could have been resolved with more runway.
The recurring issues are predictable. Owner dependence is the most common: when customer relationships, pricing, and daily decisions all run through the founder, a buyer sees value that may walk out the door at closing, and responds by lowering the price or tying the owner to future results. Concentrated customers, informal or inconsistent financial records, and undocumented processes each cut the same way. None of these problems is fatal, but each takes time to address, and time is the one input an owner cannot add once a buyer is already at the table.

It is tempting to treat the decision to sell as a timing question, a matter of catching the right market. Forecasts for 2026 point to modest growth in deal activity, with M&A volume expected to rise in the low single digits and private equity deal counts projected to grow somewhat faster, so conditions are constructive. But timing rewards owners who are ready to act on it, and readiness takes longer to build than most expect. A credible preparation window runs two to three years, long enough to strengthen management, clean up reporting, and address concentration, and long enough to sell from a position of choice rather than necessity.
The wave itself argues for starting early. As more companies reach the market, buyers can afford to pass on the ones that require work and wait for the ones that do not. Owners who begin preparing before they intend to sell keep the widest set of options open, including the option to wait for a better offer. Those who start only when they are ready to leave often discover that the market is ready to negotiate, but not on their terms.
The succession wave is a demographic certainty, not a market forecast, and it cuts both ways. It will bring an unusually large volume of businesses to market over the next decade, and it will give selective buyers their pick of them. The owners who do well will not be the ones who time the market most cleverly; they will be the ones who spent two or three years making their companies straightforward to buy. Preparation, more than timing, will determine who sells into this wave and who joins the majority that cannot.
