Greater Philadelphia’s economy is carried by companies of every size, from the region’s largest employers to its smallest storefronts. Sitting between them, and too often overlooked, is a segment our region rarely stops to name: the middle market.
When we talk about the companies that define Greater Philadelphia, the conversation naturally turns to its most visible anchors, and for good reason. The global corporations, health systems, and universities that anchor our region have shaped it for generations. Their investment, their payrolls, and their civic leadership are central to Greater Philadelphia’s strength, and the Chamber counts many of these institutions among our closest partners.
That conversation is not wrong. It is simply incomplete. Companies generating tens or hundreds of millions of dollars in annual revenue, no longer small but not yet operating at the scale of our region’s largest employers, rarely enter that conversation at all. Not in the business press, not in economic development pitches, and not often enough in the story our region tells about itself.
Naming that gap is not about diminishing what our region’s largest employers or its small businesses contribute. It is about making sure the companies in between get the same recognition their contribution to this region has already earned.
An economy built on the middle, not the margins
Greater Philadelphia’s middle market, companies generating between $10 million and $1 billion in annual revenue, includes an estimated 3,750 companies across our region. Together, they employ roughly 1.3 million people and generate more than $253 billion in combined annual revenue, according to the National Center for the Middle Market, the research institution at The Ohio State University’s Fisher College of Business that has served as our region’s research partner on this work.
These figures deserve real attention. A relatively small share of our region’s companies is responsible for well over a million jobs and a quarter-trillion dollars in annual economic output. That is not a footnote to Greater Philadelphia’s economy. It is the foundation.
Other regions built their economic identity around concentration: San Francisco around technology, New York around finance, Detroit around a small number of legacy manufacturers. Greater Philadelphia took a different path, one that has proven durable. Our region’s economic strength was never rooted in a handful of giants. It has always come from a deep bench of serious, mid-sized, privately held companies across manufacturing, professional services, healthcare, logistics, and technology. These are companies with the scale to matter and the independence to keep growing on their own terms.
That is not a gap in our region’s story. It is our region’s story, and it is one we have not told well enough.
A segment that deserves its own spotlight
The middle market’s low visibility is not a judgment on the value of our region’s largest employers or its small businesses. Both are essential to Greater Philadelphia, and both have support systems built specifically around them. Small businesses benefit from the SBA, SCORE, and a wide network of state and local programs designed around their stage of growth. Our region’s largest employers bring the scale, investment, and civic partnership that anchor entire industries and, in turn, this Chamber’s own work on behalf of the region.
The middle market sits in a different position. These are companies that have often outgrown small-business resources but have not yet reached the scale, or the visibility, of the region’s largest employers. That in-between position can mean less tailored attention, not because these companies matter less, but because the support built around the two ends of the size spectrum was never designed with them specifically in mind. Naming that gap, and closing it, is exactly the role the Chamber is positioned to play.
The national data underscores the opportunity. Middle market companies represent roughly one-third of private-sector GDP and employment nationally, and they generate approximately 60 percent of all new private-sector jobs in a given year. Greater Philadelphia’s version of this story carries the imprint of our region’s particular strengths: an industrial base that never fully hollowed out, a professional services sector with genuine depth, a port and logistics network growing more central to the regional economy rather than less, and a health care and life sciences ecosystem built over decades. The companies operating within that foundation are not chasing a single emerging sector. They are the foundation itself.
Why this matters to Greater Philadelphia now
This is not simply an interesting data point about the composition of our regional economy. It has direct bearing on how well positioned Greater Philadelphia is for what lies ahead.
Our region is entering a period in which its ability to make an accurate, compelling case — to talent considering where to build a career, to capital deciding where to invest, to companies weighing where to expand — will matter more than it has in a generation. Major events are bringing outside attention to Greater Philadelphia at a scale not seen in years. Budget and tax policy decisions being made at the state and local level right now will shape how competitive our region’s cost of doing business is relative to its peers. The infrastructure supporting our region’s supply chains is either receiving the investment it needs, or it is not.
Every one of these conversations depends on whether the people advocating for Greater Philadelphia can describe this region’s full economy, not only its largest employers and its smallest storefronts, but the substantial, fast-growing companies in between. Leaving that segment out of the picture means making the region’s case with an incomplete one.
The Chamber of Commerce for Greater Philadelphia has worked to put a spotlight on this often-overlooked segment for years. Through our Middle Market initiative, we connect these companies with the peer relationships, research, and advocacy suited to where they are in their growth, alongside the support the Chamber provides to small businesses and the partnerships we maintain with our region’s largest employers. Recognizing the middle market does not come at the expense of any other part of Greater Philadelphia’s economy. It completes the picture, ensuring every stage of a company’s growth is represented in how we tell this region’s story.
That recognition is the foundation this work is built on. We will continue to look at where our region’s middle market faces real exposure, where it is positioned to lead, and what its leaders should be watching closely in the months ahead. We invite you to learn more about the Chamber’s work on behalf of Greater Philadelphia’s middle market.
