Interactive Brokers Group (IBKR) recently used its appearance at the Morgan Stanley US Financials Conference 2026 to highlight growth in customer accounts, account equity, and net interest income, along with a higher quarterly dividend.

That message has landed against a strong market backdrop for Interactive Brokers Group, with a 30 day share price return of 18.01% and a year to date share price return of 42.79%. The 1 year total shareholder return of 87.85% and very large 5 year total shareholder return signal that momentum has been building over both shorter and longer horizons.

So, with Interactive Brokers Group rallying strongly and trading above the average analyst target while still screening at roughly a 30% intrinsic discount, is there real value left here, or is the market already pricing in future growth?

Most Popular Narrative: 10.3% Overvalued

Interactive Brokers Group last closed at $96.00, while the most widely followed narrative anchors fair value at $87.00. This creates a gap that hinges on how sustainable current growth and profitability assumptions prove to be.

The introduction of new products and enhancements, such as the strengthened ATS with new liquidity providers and order types, enhancements to the IBKR Financial Advisor Portal, and the launch of securities lending for Swedish stocks, suggests potential for increased trading activity and higher commission revenue.

Curious what kind of revenue path and margin profile could justify that fair value when analysts already factor in rising earnings and a lower future P/E multiple? The full narrative lays out a tight set of growth, profitability and valuation assumptions that connect IBKR's current expansion efforts to that $87.00 figure.

Result: Fair Value of $87.00 (OVERVALUED)

However, Interactive Brokers Group still has to contend with interest rate swings that could affect net interest income, as well as stiff competition that may pressure growth assumptions baked into this narrative.

Another View: SWS DCF Model Flags IBKR as Undervalued

The analyst consensus narrative pegs Interactive Brokers Group at a fair value of $87.00 and calls the stock overvalued, yet the Simply Wall St DCF model points in the opposite direction. At a share price of $96, IBKR is assessed as trading about 30% below an intrinsic value of $137.80, which frames current pricing as a potential discount rather than excess. Which lens do you trust more when both are built on different sets of assumptions?
