Daily financial news network headlines are overwhelmingly dominated by the Mega Corporations, Fortune 100 tech conglomerates, multinational banks, and massive retail chains. One would think the US economy hinges on what happened today with the Dow, NSDAQ, Meta, Nivida, OpenAI, Google, Microsoft, or one of the industrial giants. These are the headlines and click bait, but they are not the true economic engine of the US.
While the daily news is focused exclusively on Wall St and big business, small and midsize businesses quietly, invisibly, chug along driving the US economy and servicing our daily needs. The true foundation of the U.S. economy is found on the Main Streets, local industrial parks, and home offices. Small and mid-sized businesses—often operating entirely under the national radar—are the lifeblood of US economic output, job creation, and localized wealth generation.
These small businesses also represent opportunities for entrepreneurs and those stuck in the corporate workforce to buy a small business and build wealth. The vast majority of these businesses are owned by Baby Boomers at or nearing retirement age and after owning their own business for 20 or more years, they are now ready to retire.
The National Picture: A Look at the Numbers
To understand the sheer volume of small businesses, we have to look at the numbers by revenue size. When we break down the nearly 15.8 million businesses operating in the U.S., a staggering reality emerges: the vast majority of companies are under $5 million in annual revenue!
The Small & Midsize Business Reality:
Over 97% of all businesses in America generate less than $5 million in annual revenue, and this combined cohort contributes nearly a third (32%) of the total U.S. Gross Domestic Product.
While massive corporations (those over $100M) generate nearly half of the GDP value, they represent roughly one-fifth of one percent (0.21%) of the business population.
| U.S. Annual Revenue Range | Business Population | % of U.S. Businesses | % Contribution to U.S. GDP |
| $0 to $1 Million | 14,710,881 | 92.91% | 18.2% |
| $1 Million to $5 Million | 769,313 | 4.86% | 13.8% |
| $5 Million to $10 Million | 144,641 | 0.91% | 4.8% |
| $10 Million to $25 Million | 105,600 | 0.67% | 5.6% |
| $25 Million to $50 Million | 42,400 | 0.27% | 4.5% |
| $50 Million to $100 Million | 28,000 | 0.18% | 5.2% |
| Over $100 Million | 32,901 | 0.21% | 47.9% |
The mid-market tier—businesses generating between $5 million and $100 million—acts as the crucial bridge, comprising just 2% of firms but driving over 20% of the U.S. GDP. This mid-market is where significant M&A activity occurs and where enormous generational wealth is transferred.
California Small & Midsize Business:
The Crown Jewel of American Business
You cannot discuss the American economy without discussing California, and you cannot talk about the California economy without looking at small and midsize businessess.
If California were an independent country, it would rank as the 5th largest economy in the world, routinely generating nearly $4 Trillion in GDP. California outpaces entire G7 member economies!
But what drives California’s massive output?
Just as with the national figures, it is a vast, dense network of micro, small, and medium-sized enterprises (SMEs).
| California Annual Revenue Range | Est. Business Population | % of CA Businesses | % Contribution to CA GDP | % Contribution to Total US GDP |
| $0 to $1 million | 4,120,560 | 93.12% | 19.5% | 2.47% |
| $1 million to $5 million | 207,975 | 4.70% | 14.2% | 1.80% |
| $5 million to $10 million | 38,940 | 0.88% | 5.1% | 0.64% |
| $10 million to $25 million | 28,762 | 0.65% | 5.4% | 0.68% |
| $25 million to $50 million | 12,390 | 0.28% | 4.6% | 0.58% |
| $50 million to $100 million | 7,522 | 0.17% | 5.5% | 0.70% |
| Over $100 million | 8,850 | 0.20% | 45.7% | 5.78% |
Why California Matters to the Nation
California is a high-density hub for innovation, agriculture, international trade, and entertainment. The state is home to roughly 4.4 million firms, representing approximately 13% of all businesses in the United States.
The state’s business distribution mirrors the nation but leans slightly heavier into the micro-business sector (93.12% generating under $1M), largely due to the massive presence of independent contractors in tech, gig-economy workers, and freelance entertainment professionals based in Los Angeles and the Bay Area.
Despite headlines focused on Silicon Valley giants, small businesses in California generate nearly a third of the state’s GDP and employ over 7.3 million Californians—nearly half of the state’s private workforce. They are the primary tenants of commercial real estate, the main consumers of local B2B services, and the crucial suppliers to larger enterprises.
The Takeaway for Small & Midsize Business Owners and Buyers
For entrepreneurs, investors, and prospective business buyers the data tells a compelling story. The vast majority of the American and Californian economic landscape consists of highly accessible, locally impactful businesses. Many of these businesses qualify for SBA financing which means a qualified buyer can purchase a SBA qualified business with just 10% down.
To put that in perspective, a buyer can acquire a business valued at say $1,000,0000 that one would expect to be generating between $330,000 of Discretionary Earnings and $400,000 of DE, with a $100,000 down payment!
While the $100M+ mega-corporations capture the news cycle, the $1M to $25M businesses are the ones actively driving regional growth, providing stable cash flows, and offering the most viable opportunities for acquisition and wealth creation.
Whether you are looking to acquire your first company, expand your existing operations, or finally exit the business you spent decades building, the market is incredibly vast. The engine of the economy is small business—and there has never been a better time to be in the driver’s seat.
