Introduction
The U.S. economy generated approximately $31.4 trillion in nominal GDP in 2025, with economic activity spread across financial services, professional services, manufacturing, healthcare, government, retail, information and other sectors.
The largest category in the supplied 2025 data was finance, insurance, real estate, rental and leasing, with $6.8 trillion in nominal output, equivalent to 21.8% of total U.S. GDP. Professional and business services ranked second at $4.1 trillion, followed by manufacturing at $3.0 trillion.
The distribution highlights the increasingly service-oriented structure of the U.S. economy. At the same time, manufacturing, construction, transportation and agriculture remain important contributors to national output and supply chains.
What Nominal GDP Measures
Nominal GDP measures the value of goods and services produced within an economy at current prices. Unlike real GDP, it does not remove the effect of changes in prices.
Industry GDP measures are therefore useful for understanding the monetary scale of different parts of the economy, but they should not be interpreted as measures of productivity, profitability or employment.
The sector classifications also matter. Some categories combine several related activities. For example, the largest category in the supplied data combines finance, insurance, real estate, rental and leasing, making it broader than the banking or financial-services industry alone.
America’s Biggest Industries by Nominal GDP

Finance, Real Estate and Insurance Lead the Economy
The combined finance, insurance, real estate, rental and leasing category generated $6.8 trillion, making it the largest sector grouping in the dataset.
Its 21.8% share is considerably larger than the individual manufacturing or healthcare categories. However, the figure covers several distinct activities, including financial services and real estate-related economic output.
This broad classification is important when comparing industries. A narrower definition of finance alone would produce a substantially different ranking.
Professional and Business Services Rank Second
Professional and business services generated $4.1 trillion, representing 13.1% of the economy in the supplied data.
The category encompasses a wide range of activities supporting companies and other organizations. These can include professional, scientific and technical services, administrative services and other business-oriented activities.
Its large contribution reflects the role of specialized services in the modern U.S. economy.
Manufacturing Remains a $3 Trillion Sector
Manufacturing ranked third at $3.0 trillion, equivalent to 9.4% of total GDP.
The sector covers production of physical goods across numerous industries, including durable and nondurable manufacturing.
Manufacturing’s economic importance extends beyond its direct GDP contribution. Industrial production is connected to wholesale trade, transportation, business services, energy and international trade, creating economic activity across multiple sectors.
Healthcare and Education Account for $2.8 Trillion
The combined educational services, health care and social assistance category generated $2.8 trillion, or 8.9% of GDP.
Healthcare represents a particularly significant component of the U.S. services economy, supported by household spending, employer-sponsored insurance, government programs and other sources of demand.
Education and social assistance broaden the category beyond healthcare, meaning the $2.8 trillion figure should not be interpreted as healthcare GDP alone.
Government Activity Accounts for a Significant Share
State and local government generated $2.4 trillion, or 7.6% of total GDP, according to the supplied figures.
Federal government activity added another $1.1 trillion, equivalent to 3.5%.
Combined, the two government categories represent a substantial component of measured economic output. Government GDP primarily reflects the value of services provided by government, rather than government revenue or spending being equivalent to GDP.
Wholesale and Retail Trade Each Generate About $2 Trillion
Wholesale trade contributed $2.0 trillion, representing 6.4% of total GDP.
Retail trade was also listed at $2.0 trillion, with a 6.2% share.
The two sectors occupy different positions within supply chains. Wholesalers generally operate between producers and downstream businesses, while retailers sell goods to final consumers.
Their combined scale illustrates the importance of distribution and consumer markets to the U.S. economy.
Information Is a Major Economic Sector
The information sector generated $1.8 trillion, or 5.6% of GDP.
The sector encompasses activities involving the creation, processing, distribution and transmission of information. It includes areas such as telecommunications, publishing, broadcasting, data-related services and parts of the digital economy.
The sector’s position among the largest U.S. industries reflects the growing economic significance of information-intensive activities.
Construction and Transportation Support the Wider Economy
Construction accounted for $1.3 trillion, or 4.3%, while transportation and warehousing generated $1.0 trillion, or 3.3%.
Both sectors are closely linked to other parts of the economy.
Construction supports residential, commercial and infrastructure development. Transportation and warehousing facilitate the movement and storage of goods through domestic and international supply chains.
Their GDP contributions therefore extend beyond their individual sector classifications.
Smaller Sectors Still Have Strategic Importance
The bottom four sectors in the supplied ranking were:
- Utilities: $0.49T, or 1.6%
- Mining: $0.37T, or 1.2%
- Agriculture, forestry, fishing and hunting: $0.26T, or 0.8%
- Other services, except government: $0.66T, or 2.1%
Agriculture’s relatively small share of GDP does not mean that food production is economically insignificant. Agriculture is a foundational input into food manufacturing, trade and other supply-chain activities.
Similarly, mining supplies raw materials used by manufacturing, construction and energy-related industries.
Why Industry GDP Shares Matter
Industry GDP shares provide a useful view of the structure of an economy, but they should not be confused with employment shares.
A sector can produce substantial economic output with comparatively fewer workers because of capital intensity, technology or high-value production. Conversely, labor-intensive sectors can employ large numbers of people without generating an equivalent share of GDP.
GDP also differs from corporate revenue. A company’s sales can include intermediate goods and services that would create double counting if simply added together across the economy. GDP accounting is designed to measure value added and avoid that problem.
Risks and Limitations of the Ranking
The first limitation is the use of nominal GDP. Because nominal values reflect current prices, changes can result from both changes in production and changes in prices.
The second is sector aggregation. The largest category combines finance, insurance, real estate, rental and leasing, while the fourth-largest category combines education, healthcare and social assistance. These broad groupings make direct comparisons with narrower sectors more difficult.
The third is that the supplied figures are rounded. Adding the displayed sector percentages may not produce exactly 100% because of rounding and classification differences.
Finally, GDP measures economic production rather than profitability, household welfare or the number of jobs generated by a sector.
Future Outlook for the U.S. Economic Structure
The composition of U.S. GDP will continue to reflect changes in technology, demographics, consumer demand, investment and global trade.
Information-intensive industries, healthcare and professional services remain important parts of the modern economy, while manufacturing, construction, transportation and energy-related activities continue to provide physical infrastructure and production capacity.
Changes in productivity and prices can also alter the nominal value of individual sectors without corresponding changes in the quantity of goods and services produced.
For that reason, long-term comparisons are most informative when nominal GDP is considered alongside real GDP, employment, productivity and other economic indicators.
Conclusion
The 2025 data shows that the U.S. economy is dominated by a mixture of financial and real-estate activities, professional services, manufacturing, healthcare, government and trade.
The largest reported sector grouping—finance, insurance, real estate, rental and leasing—generated $6.8 trillion, or 21.8% of the supplied $31.4 trillion total U.S. GDP. Professional and business services followed at $4.1 trillion, while manufacturing contributed $3.0 trillion.
The ranking also demonstrates why industry comparisons require careful interpretation. Broad sector classifications can combine substantially different businesses, while nominal GDP captures current-dollar economic output rather than productivity or profitability.
