If your company brings in between $10 million and $1 billion a year, you're part of the middle market. According to the National Center for the Middle Market (NCMM), a research center at The Ohio State University Fisher College of Business here in Columbus, the U.S. is home to roughly 200,000 of these companies, and they account for about one-third of private-sector GDP and employment.
That makes the segment's latest performance data worth a close look, especially if you're planning the next stage of growth.
The middle market is still growing at a healthy clip. NCMM's latest Middle Market Indicator, based on a survey fielded in June 2026, put year-over-year revenue growth at 11%. Eighty-two percent of companies grew revenue, and nearly half posted double-digit gains.
By most measures, that's a strong segment. The more useful question is how the growth is happening.
Employment growth slowed to 7.2%, its lowest level since the pandemic recovery. Just over half of companies (52%) are still adding employees, and only 6% report shrinking headcount. NCMM reads the widening gap between revenue and hiring as a sign that companies are leaning on technology, upskilling and better processes to grow, rather than simply adding people.
The gains also aren't spread evenly. In its year-end 2025 report, NCMM found that companies with $50 million or more in annual revenue were driving the increases in revenue and hiring, while lower middle market businesses grew more slowly. For companies on the smaller end, that gap is worth paying attention to. The systems that got you to $20 million may not be the ones that get you to $50 million.
Looking ahead, seven in 10 companies expect revenue growth over the next 12 months, and 59% expect to add employees through mid-2027.
AI has become the middle market's top investment priority. Nine in 10 companies now report using AI, and NCMM's data shows automation, process improvement, and workforce development close behind on the investment list.
The enthusiasm comes with real caution. More than four in five companies report concerns about adoption, including data privacy and security, implementation costs, data quality, and keeping workforce skills current. Nearly one-third of executives rank digitalization and technology advancement among their top business risks.
Those decisions rarely stay in their own lane. An AI and automation rollout changes your staffing plan, which changes cash flow, which changes your tax picture. At $10 million in revenue, a misstep is a lesson. At $200 million, it's a line item.
Expectations are shifting toward year-round advice. The most recent CPA.com and AICPA Client Advisory Services Benchmark Survey found that client advisory services remain the fastest-growing service area in public accounting, with participating practices reporting a median growth rate of 17%.
That growth tracks with what business owners want. Few mid-market leaders are looking for an accountant who shows up once a year with a return. They want someone who knows the business well enough to help plan the next move, whether that's an acquisition, a technology overhaul, or a leadership transition.
Tax and assurance work remain at the core of what GBQ does. Growing companies often need help with the harder strategic calls, too, including:
Not every company needs all of it at once. The most useful advice shows up while a decision is still being made, and it's built around your specific numbers and pressures rather than a generic playbook.
Benchmarks tell you where the market is. What they mean for your company depends on your industry, your size, and your goals. You know where you want to take the business, and we can help you map what it will take to get there. Talk to an expert on GBQ's team about what these trends mean for your next move.
NCMM defines the U.S. middle market as companies with annual revenue between $10 million and $1 billion. Roughly 200,000 businesses fall into that range, accounting for about one-third of private-sector GDP and employment.
NCMM's most recent Middle Market Indicator reported year-over-year revenue growth of 11%, with 82% of companies reporting growth and nearly half posting double-digit gains. Employment growth slowed to 7.2%.
Nine in 10 middle-market companies report using AI, and it's the top investment priority in NCMM's latest survey. Companies cite cost savings, better decision-making, and greater automation among the benefits, along with concerns about data security and implementation costs.
