The Number-Two Seat: 44% of Big-Company CEOs Came Straight From It. Most Companies Never Build One.

Ask where the next CEO of a Fortune 500 company will come from and the most likely answer is the office next door. Nearly half of the CEOs running America's largest companies today stepped up from a chief operating officer or president seat. In most growing companies there is no office next door. The CEO runs operations, the CFO acts as an informal deputy, and the succession plan is a name in a drawer. This is the story of the seat that big companies use to make CEOs, and how a smaller company can build one without overbuilding.

Where CEOs actually come from

Crist|Kolder Associates has tracked C-suite turnover at the Fortune 500 and S&P 500 for more than two decades. Its 2026 Volatility Report covers 665 companies with data through July 31, 2026, and it records the immediate previous job of every one of the 674 sitting CEOs.

The largest group by far came from a COO or president role: 44.0%, of whom 41.3 points were promoted from inside the company and only 2.7 points were hired from outside. Next came divisional presidents at 15.8%. Executives who had already been a CEO somewhere made up 13.3%. Only 7.3% came straight from the CFO chair, and 4.7% from a board seat.

Add up the internal columns and roughly four in five sitting CEOs at these companies were already working there in their previous role. The big-company pipeline isn't mainly a recruiting exercise. It's a seat, and the people who sit in it.

A chair only about a third of companies keep

Here is the surprise. The COO title itself is not common. Crist|Kolder counts 254 sitting COOs across those 665 companies, and says COO utilization has stayed stable for a decade at an average of 35.8%. Roughly two-thirds of the largest companies run without anyone titled chief operating officer. Their number two is a president, a divisional head with an enterprise remit, or a CFO with an operating brief.

The way the seat is filled matters as much as whether it exists. Of the COO hires made in 2026 to date, 84.6% were internal promotions. The chair that produces CEOs is almost always filled by someone the company has already watched work. Large companies don't buy their next CEO's track record. They build it in the number-two seat, where a leader runs the operating cadence with the CEO's full scope in view and the board can see how they handle it.

Why the mid-market skips it

Smaller companies have good reasons for not having a number two. The founder or CEO built the operation and still runs it. A COO looks like overhead before the business can carry it. The CFO is the most senior person after the CEO, so finance becomes the de facto deputy, even though only 7.3% of big-company CEOs come from that chair.

The result shows up in succession planning. In Brown Brothers Harriman's 2025 survey of 491 private and family business owners, only 46% had a formal succession plan in progress and 30% had none. The National Center for the Middle Market's study of 404 middle-market leaders, fielded in late 2019 and published in 2020, found that only 33% had concrete, written succession plans for top leadership. Companies preparing a CEO transition spent an average of 1.1 years on it, and more than 40% began planning only in the year the transition actually happened. That study is older, so treat its figures as a baseline rather than today's exact number, but nothing in the newer survey suggests the picture has improved much.

A succession plan without a number-two seat is a list of names nobody has watched run the company.

That is the real gap. A written plan names a successor. A number-two seat gives that successor two or three years of evidence. Directors who have lived through a rushed succession tend to say the same thing afterwards, which is why we argued in What Boards Owe the Next CEO that the work has to start well before the vote.

What the number-two seat actually does

Strip away the title and the seat has three jobs.

1. It takes the operating cadence off the CEO. Weekly operating reviews, capacity, hiring plans and the quarter's commitments move to one person, which frees the CEO for customers, capital and strategy.
2. It tests a successor on real scope before the title. Running the whole operation for two years tells you more than any interview loop or assessment. You see how the person handles a bad quarter, a key departure and a decision the CEO would have made differently.
3. It gives owners and the board evidence. When the succession vote comes, the board is weighing a track record inside the business, not a set of impressions from a few dinners.

COO or president: the title matters less than the scope

Crist|Kolder groups COOs and presidents together for a reason. In many companies the president runs the business day to day while the CEO handles the board, capital and the biggest customers. In others the COO owns operations but not sales, which makes the role a weaker test of a future CEO. The title tells you less than the answer to one question: does this person own enough of the business that their results would tell you how they'd run all of it?

A COO who runs the plants but has never touched pricing, a key account or the budget conversation with the owners is a strong operator, and possibly not a successor. If succession is part of the reason for the seat, write the commercial and financial scope into the role from the start, and say plainly to the person in it that the seat is a test. Most capable executives would rather know what they are being measured on than guess.

A three-year runway

Compare the 1.1 years the average middle-market company spends preparing a CEO transition with how the large-company pattern actually works. Played out over time, it looks something like this.

Three years out: decide what the number two is. A COO, a president, or an expanded role for an existing leader. Write down what that person will own, including the parts the CEO will give up, which is usually the harder conversation.

Two years out: someone sits in the seat. If there is a credible internal candidate, give them the scope and support them. If the operating system they would inherit doesn't exist yet (no reporting rhythm, no capacity model, no clear decision rights), a fractional COO can build it first and define the job properly, so that whoever takes the seat inherits a working system rather than a mess. Our Fractional COO page describes that engagement.

One year out: test the insider against the outside market, quietly. Outsiders win often enough that skipping this step is a mistake. Crist|Kolder shows 27.3% of new CEOs in 2026 to date were recruited externally, above the 24% historical average. A confidential, retained search is the right tool, because a public search for a successor tells the company, the incumbent and the insider candidate exactly what you are thinking. We explained how those searches are kept quiet, and how they are paid, in The Confidential Search.

Day one: the announcement names a successor who has already run the business, or one chosen from outside with a clear view of what the insider could and couldn't do. Either way the decision rests on evidence.

Three ways to build the seat without overbuilding it

Most companies under a few hundred million in revenue don't need to copy the Fortune 500 structure. They need the function of a number two at a cost they can carry.

• Promote and support. If you have a strong internal operator, give them the operating scope now, with a title that matches, and put senior coaching around them for the first year. This is the cheapest option and the closest to the big-company pattern.
• Fractional first. A fractional COO installs the operating rhythm, defines the role and helps you judge whether an internal candidate can grow into it. Sometimes the answer is that the company only needs the fractional, and that is a fine answer.
• Search for the number two. If nobody inside can grow into the seat in time, retain a firm to find a COO or president with the potential to succeed the CEO. Keep it confidential, because hiring a likely successor signals a transition. If the seat is empty in the meantime, a fractional executive can hold it while the search runs, which is how our Bridge-to-Hire model works.

What this is not

This is not an argument that every company needs a COO. Two-thirds of the largest companies run without one, and plenty of excellent CEOs came from divisional roles, the CFO chair or another company. The data also comes from the Fortune 500 and S&P 500, so apply it to a mid-sized company directionally, not literally. Private equity is a different case again: sponsors frequently bring in an outside CEO on their own clock, which we mapped in The Portfolio Company Leadership Clock.

The argument is simpler. The companies that are best at succession don't rely on a plan alone. They keep a seat where the next leader can be watched doing the job, and they start filling it years before they need to. If your plan is a name with no seat behind it, you have time to fix that, but probably less than you think. Our Executive Search and Fractional C-Suite pages explain how we help, and The 4.1-Year CMO looks at another seat that turns over faster than most owners plan for.
