Interactive Brokers10-Q: Internal control weaknessAug 6, 2026

IBKR discloses its margin system may fail in illiquid markets, exposing it to 'unlimited' risk on $108.9B in loans

What happened

With $108.9 billion in customer margin loans, the company admits its real-time automated liquidation system may not be effective in all scenarios, particularly in illiquid markets. This stated technology limitation represents a critical control gap and may drive investment in more robust risk management and liquidation systems that can function under stress conditions.
