Interactive Brokers Stock Has Turned $10,000 Into About $100,000 in 10 Years

Interactive Brokers has delivered impressive 10-year returns, with a $10,000 investment growing to ~$100,000, driven by surging customer accounts (up 34% YoY) and increased risk-taking including crypto and prediction markets. However, the article warns that this growth is unsustainable, as it's fueled by a bull market and elevated margin debt (up 67% YoY). When the inevitable bear market arrives, the company's business will struggle as investors reduce risk exposure.
