Interactive Brokers Group (IBKR) is back in focus after recent share price moves, with the stock closing at US$75.66. That puts fresh attention on how its current valuation lines up with recent returns.

That move to US$75.66 comes after a strong 30-day share price return of 16.40%, set against a 12.54% year to date share price gain and a 1-year total shareholder return of 38.81%. This suggests momentum has been building over both shorter and longer periods.

With the shares at US$75.66, a 30-day gain of 16.40% and a 1-year total return of 38.81%, the key question is whether Interactive Brokers Group is still trading below its worth or if the market is already pricing in future growth.

Most Popular Narrative: 401.7% Overvalued

According to the most followed narrative, Interactive Brokers Group has a fair value estimate of $15.08, which sits far below the recent $75.66 close.

Earnings Show Exceptional Profitability. Interactive Brokers (NASDAQ: IBKR) reported another standout quarter, reinforcing its position as one of the most operationally efficient brokerages in global finance. For Q3 2025, the company posted GAAP net revenues of $1.655 billion, up from $1.365 billion in the same quarter last year. Adjusted net revenues totaled $1.61 billion. GAAP diluted earnings per share rose to $0.59, compared to $0.42 a year earlier. Most strikingly, the firm delivered a pre-tax profit margin of approximately 79 percent, a level rarely matched in the industry and more than double that of many legacy brokers. Growth Driven by Trading Activity and Interest Income. Revenue growth this quarter was supported by strong trading volumes and interest income from client balances.

Curious how such high reported margins still feed into a low fair value? The narrative leans heavily on future profit assumptions and a rich earnings multiple. Want to see what that combo looks like in numbers?

Result: Fair Value of $15.08 (OVERVALUED)

However, this story could crack if interest income weakens with lower rates, or if new tokenized and crypto market structures reduce the need for traditional brokers.
