8%Interactive Brokers has launched Ethereum staking for eligible clients, letting them earn rewards on ETH holdings through its brokerage platform. Clients of Interactive Brokers LLC can stake or unstake ETH and track pending transactions from a dashboard in the Client Portal, the company said on Tuesday. Crypto infrastructure firm zerohash provides the staking services. Rewards are credited as additional staked Ethereum, so holdings compound while staked. Availability depends on a client's eligibility and jurisdiction, and Ethereum is the only supported asset for now. "Staking gives clients an opportunity to earn rewards on the cryptocurrency they own," said chief executive officer Milan Galik. The broker supports trading in 20 digital assets, with commissions of 0.12% to 0.18% of trade value and a $1.75 minimum per order. Its shares trade at $86.97.
Interactive Brokers held approximately $965 billion in client equity across 5.6 million accounts as of September, averaging roughly $173,000 per account. In contrast, Robinhood had $384 billion in platform assets spread across 28.6 million funded customers, averaging about $13,400 each. The disparity reflects their target markets. Interactive Brokers serves sophisticated investors, hedge funds, and financial advisors across over 200 countries. Robinhood primarily attracts newer investors "just beginning their financial journeys." The difference shapes their revenue models. Interactive Brokers generated 56% of its second-quarter net revenue from net interest income, which grew 23% year-over-year to $1.06 billion. Robinhood's revenue tilts toward transaction-based sources, which comprised 59% of its $1.31 billion second-quarter net revenue. Robinhood is pursuing larger balances through retirement accounts and its TradePMR acquisition, though closing the gap with Interactive Brokers will likely take years.
Interactive Brokers Group reported its September brokerage metrics, showing 4.111 million Daily Average Revenue Trades, up 6% year-over-year but down 4% from August. Client equity reached $964.7 billion, 27% higher than the previous year. The company's client accounts grew to 5.576 million, a 35% annual increase. Client margin loan balances rose to $105.2 billion, up 36% year-over-year and 4% month-over-month. Credit balances totalled $186.2 billion, including $6.4 billion in insured bank deposit sweeps, marking a 20% annual increase. The average commission per cleared order stood at $2.57, including exchange, clearing and regulatory fees. For US Reg-NMS stock trades, IBKR PRO clients' total execution and clearing cost was approximately 1.2 basis points of trade money in September.
Interactive Brokers shares trade near $89, roughly 10% below their 52-week high. The stock trades at 29 times next year's expected earnings—a growth stock valuation for a brokerage. For shares to double by late 2031, requiring roughly 15% annual growth, the company would need to double its earnings per share. Interactive Brokers is currently exceeding this bar. In the first half of 2026, net interest income grew 20% year over year, commission revenue rose around 25%, and earnings per share climbed 30%. Net interest income, the company's largest revenue line at 57% of 2025 net revenues, grew despite Federal Reserve rate cuts. Customer credit balances reached $185.6 billion at end-August, up 27% year over year, whilst margin loans hit $101.5 billion, up 41%. The company already converts roughly 77% of net revenues into pre-tax profit, leaving little room for margin expansion.
Interactive Brokers shares have surged approximately tenfold over the past decade, turning a $10,000 investment in September 2016 into roughly $110,000 with dividends reinvested. The stock delivered about 27% annual returns, more than double the S&P 500's 15% over the same period. The brokerage's customer base drove this growth, expanding nearly 15-fold from 370,000 accounts in September 2016 to 5.46 million by August 2025. Customer equity on the platform grew from $82.7 billion to $962.8 billion. Notably, growth has accelerated as the base expanded, with customer accounts rising 35% year-over-year by August 2025. Net interest income from customer cash and margin loans became the company's largest revenue source, reaching $1.06 billion in the second quarter of 2025.
