Interactive Brokers Group (IBKR) has drawn fresh attention after reporting year over year gains in daily average revenue trades, client equity, and client accounts, alongside new crypto trading features for European and existing clients.

That product push into crypto comes as momentum in the shares has cooled recently, with a 7 day share price return of 7.74% and a 90 day share price return decline of 5.85%, while longer term total shareholder returns over 1, 3 and 5 years remain very strong. This suggests sentiment has shifted from rapid rerating to a focus on how current initiatives sustain that track record.

With the shares up 91.2% over the past year but easing back over the past quarter, and analysts’ average price target sitting above the current US$68.62 level, the key question is whether IBKR still offers upside or if the market has already priced in future growth.

Most Popular Narrative: 355% Overvalued

According to the most widely followed narrative, Interactive Brokers Group’s fair value of $15.08 sits far below the last close at $68.62. This frames the current price as rich versus that narrative anchor.

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.

The narrative leans heavily on unusually high profitability and efficiency, then feeds those margins into a future earnings profile that supports a much lower fair value. Want to see exactly which earnings paths and profitability assumptions sit underneath that conclusion?

Result: Fair Value of $15.08 (OVERVALUED)

However, this view could be challenged if IBKR’s high margins prove less durable than expected or if trends in interest rates and trading volumes weaken key revenue streams.

Another View: Earnings Power Vs Price

That $15.08 fair value comes from a narrative model, but the current P/E of 31.1x tells a slightly different story. IBKR trades below the US Capital Markets average of 36.1x, yet well above the peer average of 21.3x and an estimated fair ratio of 19.2x. This points to meaningful valuation risk if sentiment cools.
