Record net revenues and commissions were driven by a 'risk-on' environment where clients increased leverage through margin loans and derivatives positions.

Maintained industry-leading pre-tax profit margins of 77% for the seventh consecutive quarter by automating core brokerage functions and scaling via AI-enhanced onboarding and compliance.

Strategic expansion into the South Korean market capitalized on high client demand for memory chip companies and semiconductor names.

The 34% growth in new accounts successfully drove uninvested cash balances to a record $182 billion, despite high levels of market reinvestment by active clients.

Introduced 'IBKR Connector' to integrate AI chatbots (OpenAI, Anthropic, xAI) directly with trading accounts, simplifying complex portfolio analysis and trade preparation for retail users.

Achieved a 40% increase in client equity to $930 billion, supported by strong institutional and individual interest across all global regions.

Overnight trading volumes nearly tripled year-over-year, reflecting the growing importance of 24-hour market access for the firm's international investor base.

Management expects the national trust bank charter to be operational by year-end, enabling the firm to directly custody assets for mutual fund and ETF customers.

Net interest income sensitivity is estimated at $81 million for every 25 basis point move in the Fed funds rate, based on June 30th balances.

The firm plans to evolve its AI capabilities from 'human-in-the-loop' trade approval toward fully autonomous agentic trading, pending the development of strict safety guardrails.

Strategic focus for Prediction Markets will remain on economic, political, and climate contracts that serve as precise hedging tools for client portfolios, rather than sports or entertainment.

Duration of the investment portfolio was slightly extended as the U.S. yield curve turned positive, while maintaining a tight maturity match between assets and liabilities.

Execution and clearing costs were impacted by a $19 million increase due to the reinitiation of SEC regulatory fees, which are largely passed through to customers with no impact on net profit.

Excess capital reached $10.3 billion, an increase of $1.1 billion sequentially, providing a significant buffer for potential strategic acquisitions.

The public company's effective tax rate of 14.7% was lower than the typical range due to tax effects from the appreciation of IBKR stock within employee incentive plans.

Management noted a clear uptick in broker transfers from competitors following regulatory clampdowns in mainland China, while maintaining strict compliance by not advertising in that region.
