TROW vs IBKR Comparison

T. Rowe Price provides asset management services for individual and institutional investors. It offers a broad range of no-load US and international stock, hybrid, bond, and money market funds. At the end of July 2025, the firm had $1.703 trillion in managed assets, composed of equity (50%), balanced (35%), fixed-income and money market (12%), and alternative (3%) offerings. Approximately two thirds of managed assets are held in retirement-based accounts, which provides T. Rowe Price with a somewhat stickier client base than most of its peers. The firm also manages private accounts, provides retirement planning advice, and offers discount brokerage and trust services. The company is primarily a US-based asset manager, deriving less than 10% of its AUM from overseas.

Interactive Brokers is a large, automated, retail and institutional brokerage that boasted nearly $570 billion in customer equity at the end of 2024. The company cut its teeth as a market maker, introducing US financial markets to automated and algorithmic training before expanding into brokerage services in 1993. The firm has a wide-ranging client base, with its best-in-class order execution and extremely low margin lending rates catering to a sophisticated audience of hedge funds, proprietary traders, and introducing brokers that account for about 45% of the firm's commissions. With operations spanning more than 160 electronic exchanges, 36 countries, and 28 currencies, Interactive Brokers caters to a global clientele, with more than 80% of active accounts sitting outside the US market.
