Revealed: The 20 Most Profitable U.S. Industries (Latest 2026 Data)
Updated: June 1, 2026
Kentley Insights has unveiled its latest, data-driven research highlighting the top 20 most profitable industries in the United States. This exclusive analysis sheds light on a complex mix of sectors where financial services, technology, and various service industries take the lead, offering critical insights for investors, strategic planners, and business owners.
Nationwide, only 62% of U.S. companies manage to generate net income, and among those profitable companies, the average net income margin stands at 10.9%. This underscores the importance of considering not only the profit margin but also the proportion of profitable companies within an industry and the capital required to operate when assessing an industry’s attractiveness for investment and strategic growth initiatives, as detailed by the Internal Revenue Service (IRS).
Why This Analysis Matters: Expert Commentary
The top performers show significant disparities, reflecting unique market dynamics and high barriers to entry.
- Trust, Fiduciary & Custody Activities (NAICS 523991): Topping the 2026 list, trust and fiduciary services capture extraordinary margins through fee-based asset management, custody arrangements, and institutional mandate work that demands deep regulatory expertise. 85.3% of firms in this category report net income — unusually high for a top-ranked sector — reflecting the recurring, relationship-driven nature of fiduciary engagements. The business model generates revenue largely proportional to assets under administration rather than transaction volume, insulating margins from market-volume swings. For a detailed breakdown, see our Financial Services Market Research Reports.
- Self-Storage (39.5% Profit Margin): A perennial high-margin performer, self-storage leverages a model of high upfront real estate costs followed by low operating expenses and recurring revenue. 43.9% of firms are profitable, and those that succeed continue to command strong returns as demand from life-transition events, downsizing, and e-commerce fulfillment keeps occupancy rates elevated. Revenue for the sector reached $35.6 billion in 2025 and is forecast to grow to $36.6 billion in 2026. Learn more in the Self-Storage Industry Report.
The list also provides insights into sectors that, while not leading in terms of margin, show a high percentage of profitable companies, such as legal services (77.2% profitable) and savings institutions (84.2% profitable). This demonstrates a robust, widespread industry health essential to a stable business environment.

Industries Combining High Growth and High Profitability
Profit margin alone is only half the picture. The most strategically compelling opportunities are industries where high net income margins persist alongside strong revenue expansion — a combination that sustains above-average returns as the market grows rather than compressing them.
The following industries cleared a dual screen: net income margin at or above 40% and a 5-year revenue CAGR (2020–2025) at or above 10%. Together, these six sectors represent the intersection of structural profitability and durable demand growth.

Packaged Software & Games NAICS 5112 53.1% Net Margin +13.3% 5-Yr CAGR $727B 2026 Rev. Cloud-native delivery has lowered distribution costs, while AI-assisted development tools are compressing time-to-release. Revenue is forecast to reach $727 billion in 2026, with margins anchored by high switching costs and subscription-model lock-in. See our Fastest Growing Services Industries page for additional context. |
Biological Product (except Diagnostic) Manufacturing NAICS 325414 41.7%Net Margin +12.0%5-Yr CAGR $92.3B2026 Rev. GLP-1 receptor agonists, cell & gene therapies, and next-generation vaccines are reshaping the biologics pipeline. The 2026 revenue forecast of $92.3 billion reflects a 12.0% CAGR from 2020, driven by premium pricing power on novel therapeutics with limited biosimilar competition. |
|
Electronic Computer Manufacturing NAICS 334111 44.5% Net Margin +10.7% 5-Yr CAGR $16.4B 2026 Rev. Enterprise AI workstations and high-performance computing builds are driving a sustained hardware refresh cycle. Revenue grew from $8.8B in 2020 to a 2026 forecast of $16.4B — a near-doubling in six years — while margins have held above 44% on proprietary architecture premiums. |
Intellectual Property & Brand Licensing NAICS 533 66.4% Net Margin +10.6% 5-Yr CAGR $83.4B 2026 Rev. Asset-light and structurally defensive, IP & brand licensing benefits from compounding royalty streams. The emerging use of AI-generated content is raising new questions about IP ownership and licensing scope — a dynamic that could expand the total addressable market for established rights holders. Revenue is projected at $83.4B for 2026. |
|
Self-Storage NAICS 53113 45.9% Net Margin +10.5% 5-Yr CAGR $36.6B 2026 Rev. Self-storage compounds margin durability with reliable demand drivers: urban housing constraints, small-business inventory needs, and household life transitions. Revenue REIT consolidation continues to push operating efficiency, while dynamic pricing optimization tools are lifting average revenue per unit. |
Loan Brokers NAICS 52231 48.9% Net Margin +10.2% 5-Yr CAGR $32.6B 2026 Rev. Fee-based intermediation with minimal balance-sheet exposure yields unusually clean margins in the credit intermediation space. Revenue grew from $19.3B in 2020 to $31.4B in 2025, with 2026 forecast at $32.6B as rate normalization encourages refinancing activity and new loan origination. |

Key Trends Shaping Industry Profitability in 2026
Several structural forces are either widening or compressing margins across the industries tracked in this analysis. Understanding these dynamics is essential context for any profitability comparison.
AI Adoption: Margin Expansion in Software & Financial Services
Across software publishing, financial brokerage, and information services, AI-assisted workflows are reducing headcount-per-dollar-of-revenue. This is visible in the data: the highest CAGR industries in this ranking are disproportionately software- and data-intensive, where AI is widening the gap between revenue growth and cost growth.
Demographic Demand: Biological & Pharmaceutical Tailwinds
An aging U.S. population is underpinning structural demand for biologics, pharmaceutical preparations, and specialty therapeutics. The biological product manufacturing sector's 12.0% CAGR from 2020–2025 — well above the manufacturing sector average — reflects this dynamic. GLP-1 therapies alone are reshaping drug-mix revenue projections through 2026 and beyond.
Onshoring & Supply Chain: Semiconductor and Industrial Tailwinds
Federal semiconductor investment under the CHIPS and Science Act continues to accelerate domestic fab capacity, supporting strong revenue growth for semiconductor manufacturers. The 2026 forecast of $81.5B for NAICS 334413 reflects both demand recovery and new domestic supply commitments. This is a multi-year structural tailwind, though margin sustainability will depend on capacity utilization once new fabs come online.
Interest Rate Normalization: Mixed Impact on Financial Services
Rate normalization is a double-edged factor in this data. For loan brokers and commodity brokerage, lower short-term rates are reviving transaction volumes. For real estate loan providers and savings institutions, net interest margin compression remains a near-term profitability risk as deposit costs lag rate reductions. Investors evaluating financial sector profitability should benchmark individual institutions against industry benchmarking metrics rather than sector-level averages.
