Interactive Brokers Group (NASDAQ: IBKR) reported record pre-tax profit for the third quarter on 15 October 2026, with margins above 70% for an eighth consecutive quarter.
The brokerage posted a pre-tax margin of 78% on GAAP net revenues of $1.91bn, according to its Form 8-K filed with the SEC. Shares fell nonetheless, last changing hands at $85.49, down 5.5% over 20 days despite a 0.71% gain in the latest session, according to consolidated US exchange data.
Record profit, stock falls anyway
Diluted earnings per share came in at $0.69 on a GAAP basis, or $0.67 adjusted, up from $0.59 a year earlier, the filing shows. Revenue of $1.914bn beat the consensus estimate of $1.888bn, as first reported by Benzinga. But the adjusted EPS figure of $0.67 missed the $0.68 analyst estimate cited by Benzinga, even as Zacks’ headline described the quarter as matching estimates – a discrepancy that reflects different consensus benchmarks rather than a restatement.
Commission revenue rose 12% year-on-year to $602m, the third straight quarter above $600m, Benzinga reported. Net interest income climbed 19% to more than $1.1bn. Customer accounts grew more than 30% year-on-year, while daily average revenue trades rose 18% to 4.3 million.
The balance sheet expanded alongside trading activity. Total assets climbed 21% to $243bn and firm equity rose 19% to $23.3bn, with no long-term debt on the books, according to figures reported by MarketBeat.
Dividend increase and new markets
The board raised the quarterly dividend to $0.15 a share from $0.0875, lifting the annualised payout to $0.60 from $0.35. Management also used the call to detail a push into new products and geographies: cryptocurrency staking for eligible clients, launched on 13 October 2026 through a partnership with Zerohash, alongside enhanced AI trading tools.
The firm added Brazilian futures trading via the B3 exchange, announced in August, and is rolling out margin lending and passkey second-factor authentication in Japan – a market executives described as culturally and regulatorily difficult to penetrate, according to a transcript of the call carried by Investing.com.
A longer run of quarterly gains
The quarter extends a run of sequential improvement at the brokerage. Diluted EPS has risen in each of the past three quarters, from $0.59 in the first quarter of 2026 to $0.69 by the third, having climbed from $0.51 and $0.59 in the second and third quarters of 2025, SEC filings show. Quarterly revenue has followed a similar path, rising from $592m in the first quarter of 2025 to $760m by the second quarter of 2026, according to figures disclosed in successive 10-Q filings.
That trajectory contrasts with the choppier results IBKR posted in its early years as a public company. Net income swung between roughly $7m and $22m a quarter through 2011 to 2013, regulatory filings from that period show, underlining how far trading volumes and margins have scaled since the firm’s public listing.
Macro backdrop and positioning
The results landed against a steady rate backdrop. The 10-year US Treasury yield stood at 5.19% on 14 October 2026, little changed from 5.21% previously, while the 2-year yield edged up to 4.82% from 4.79%, according to data from the Federal Reserve Bank of St Louis. The yield curve, measured by the 10-year/2-year spread, narrowed slightly to 0.33 percentage points from 0.37.
Short interest in IBKR shares had been elevated in the fortnight before the results, with FINRA’s daily short-sale ratio running as high as 0.596 on 2 October before easing to 0.309 by 15 October, the day of the release – a decline consistent with the broader run-up in trading volume around the earnings date. Volume on the stock ran 41% above its 20-day average as of the latest session, consolidated exchange data show, with shares trading between $81.27 and $91.85 over the preceding 20 days.
Investors will next watch IBKR’s fourth-quarter update for signs of whether commission growth above $600m a quarter and net interest income gains can hold as the Federal Reserve’s rate path and US labour market data – unemployment ticked up to 4.2% in September from 4.1% – feed through to trading activity and margin lending demand.
