United States Securities Brokerage Market Size and Share - Growth Analysis Report and Forecast Trends (2026-2035)

The United States Securities Brokerage Market was valued at USD 98 Billion in 2025 and is projected to reach USD 175 Billion by 2035, expanding at a CAGR of 7.5%. The US securities brokerage industry - encompassing retail investor discount brokerage, institutional trading, full-service wealth management brokerage, and digital-native mobile trading platforms - operates the world's deepest and most liquid capital markets. The 2020 adoption of commission-free trading by all major US retail brokerages (Schwab, Fidelity, TD Ameritrade) permanently altered the industry's revenue model from transaction commissions toward net interest income (on margin balances and uninvested cash), payment for order flow (PFOF), asset management fees, and advisory service revenue. Market growth is driven by rising retail investor participation, AI-powered investment tools, options trading proliferation, and record US equity market valuations generating management fee revenue on growing client asset bases.

Key Market Trends & Insights

• Zero-Commission Trading Model Entrenchment: Zero commission equity trading - now universal across US retail brokerages - has shifted revenue toward net interest income, PFOF, advisory fees, and premium service subscriptions, fundamentally restructuring brokerage economics and competitive dynamics.
• Options Trading Democratisation: The explosive growth in US retail options trading - with daily options contracts volume exceeding 50 million in 2024 - has created a high-revenue activity for brokerages generating per-contract fees and premium platform subscriptions from sophisticated retail traders.
• AI Investment Advisory Integration: Robo-advisor platforms (Schwab Intelligent Portfolios, Betterment, Wealthfront), AI-powered stock screening tools, and natural language investment research are transforming the advice-to-execution continuum for both self-directed and advised retail investors.

• Charles Schwab's acquisition of TD Ameritrade (completed 2020) created the dominant US retail brokerage with approximately USD 9 trillion in client assets under management - a structural competitive advantage in NII and advisory revenue generation.
• SEC's PFOF (payment for order flow) regulatory review under Chair Gary Gensler created near-term uncertainty for retail brokerage revenue models, though major PFOF changes remained pending through 2024.

Summary Table

Market Dynamics & Key Trends

1. Retail Investor Participation and Wealth Accumulation

The US retail investing renaissance - catalysed by pandemic-era stimulus savings, commission-free trading accessibility, and mobile-first trading platforms - has created the largest US retail investor cohort in history. Robinhood's 23+ million funded accounts, Fidelity's 50+ million retail brokerage accounts, and Charles Schwab's 35+ million active brokerage accounts collectively represent a massive retail asset base generating net interest income, advisory fee revenue, and premium service subscription income. Record US equity market levels - S&P 500 above 5,000 for the first time in 2024 - have generated significant managed account appreciation that scales advisory fee revenue without proportional cost increases.

2. Options Trading Boom and Revenue Expansion

US retail options trading volume surpassed 50 million contracts per day in 2024 - a 500% increase from 2019 levels - creating a high-revenue activity for brokerages that charge per-contract fees (typically USD 0.50-USD 0.65 per contract) even while equity trades are commission-free. Robinhood's options trading prominence, Tastytrade's institutional-grade retail options platform, and Charles Schwab's TD Ameritrade thinkorswim platform serve retail options traders ranging from casual covered call writers to sophisticated multi-leg spread traders. CBOE data shows retail investor options participation growing from approximately 10% to approximately 30% of total US options volume between 2015 and 2024.

3. Net Interest Income and Cash Management Revenue

Post-2022 Federal Reserve rate environment - with federal funds rate at 5.25-5.50% through 2024 - has been exceptionally favourable for brokerage NII, as firms earn spread between their investment returns on client cash and the below-market rates paid on brokerage cash sweep accounts. Charles Schwab reported NII as its largest single revenue line at approximately USD 10+ billion annually at peak 2023 rates, demonstrating how zero-commission trading enabled higher-margin alternative revenue streams through cash management monetisation. The 2024 Fed rate cut cycle will moderate NII but not eliminate it as a primary revenue line.

4. Digital Wealth Management and Robo-Advisory Growth

AI-powered automated investment management - from Schwab Intelligent Portfolios' tax-loss harvesting robo-advisory to Betterment's goal-based financial planning - serves US investors seeking low-cost diversified portfolio management without full-service adviser relationships. US robo-advisory AUM has grown from near-zero (2012) to approximately USD 1.8 trillion (2024), generating advisory fee revenue at 0.25-0.50% AUM annually. Fidelity Go (zero-fee robo), Vanguard Digital Advisor, and TIAA robo serve cost-conscious investors while generating ancillary revenue from fund management fees embedded in portfolio construction.
