Interactive Brokers Raised Everything — Except Its Customers' Trading Activity
A record 78% pretax margin, a 71% dividend hike, and a new autonomous-AI product. The tell is what per-account behavior did while accounts kept surging.

Record Numbers, A Skeptical Tape
Interactive Brokers closed fiscal Q3 with a record pretax profit and a 78% pretax margin — the eighth consecutive quarter above 70% — on commissions of $602M (+12% y/y) and net interest income north of $1.1B (+19%). Total assets climbed 21% to $243B, firm equity rose 19% to $23.3B, and there is still no long-term debt. Accounts grew better than 30%, the run-rate management has now beaten for several quarters. “I do not see any reason why our account growth would slow down” — Thomas Peterffy, Founder and Chairman · 2026-01-20, Thomas Peterffy insisted back in January — and he has refused to call a slowdown ever since.The tape disagrees. Shares peaked at 98.19 on Aug 25 and have since given back 12.4%; the last 90 days are essentially flat. So the interesting question is not the record itself — it is what management is doing with it, and what it quietly stopped celebrating.
The Dividend Is a Formula, Not a Flush
The headline capital-markets action was a 71% dividend hike, from $0.35 to $0.60 a year. But Peterffy framed it with unusual mechanical candor: “We have generally been following the guideline of paying dividends between half and one percent of the market value... we are trying to catch up here.” — Thomas Peterffy, Founder and Chairman of the Board of Directors · 2026-10-15 That is a founder describing payout as a yield target tied to market cap, not as a celebration of a windfall. When Brennan Hawken asked whether a market drawdown could push the yield above the band and force a cut, the answer was categorical:A market-cap-linked formula plus a permanent floor is an unusual pairing — it signals confidence in the compounding equity base rather than the quarter. The numbers back it: net income of $1.3B, up 33% year on year, sits on top of $64.3B of effective net cash, up 29%.I don't think that we will ever cut the dividend, at least not in any situation that I can imagine sitting here right now.
Tax Aware: A Land Grab With a Countdown Clock
The freshest company-unique thread is Tax Aware long-short strategies for registered investment advisors — a theme that did not exist in this company's trajectory a quarter ago. Roughly $300M was live by quarter-end, with AQR among the providers, but onboarding is moving "more slowly than we would like." What turns it into a story is the catalyst the analysts surfaced: a large custodian is imposing a $100M minimum on RIAs, and CEO Milan Galik is openly targeting the displaced. “anybody under $100 million is supposed to find a new home. I completely agree with you. We are one of the obvious choices, if not the obvious choice.” — Milan Galik, Chief Executive Officer, President · 2026-10-15 This is IBKR pointing its core plumbing — margin financing, short selling, securities lending — at a wealth channel it historically reached through broker partners rather than advisors, and it lands alongside a broad industry scramble for net-new assets that peers like Morgan Stanley are also emphasizing (new asset). IBKR is trying to convert cheap infrastructure into share gains in a segment where it has long been under-indexed.Autonomous AI Trading Ships — Quietly
Second fresh keyword: Autonomous AI Trading. Last quarter Galik described fully robotic execution as a future promise — “We are going to be offering, at some point, fully autonomous agentic trading.” — Milan Galik, President and CEO · 2026-07-21 That "at some point" is now. “approximately 3,000 clients of ours were invited over the last several days... we expect them to become more comfortable with AI making trading decisions on their behalf.” — Milan Galik, Chief Executive Officer, President · 2026-10-15 The scale is a rounding error for now, but the strategic pivot — from human-in-the-loop to robots in the driver's seat — is exactly the product laddering IBKR uses to defend its active-trader niche, alongside a Japan build-out and prediction-market breadth (Kalshi, CME, a pending Polymarket integration, and Cboe's single-stock contracts).The Number Nobody Led With
Underneath the records came the uncomfortable detail, surfaced by Chris Allen: “Trading activity per account dipped to the, to the lowest level in quite some time.” — Christopher Allen, Analyst · 2026-10-15 Galik's answer was a flat "broad-based." Share volumes fell 24% y/y; commission per order slipped 4% to $2.59; DARTs still grew 18%. The engine is account accumulation, not per-account engagement — and that is the tension under a 30% account-growth headline.The larger inflection is the rate regime. For a year, this company's own history was dominated by the mirror image of today's setup — "lower benchmark," "rate cuts in several countries" — as a drag. That has flipped. The Fed raised in mid-September, and CFO Paul Brody now flags the tailwind, noting the timing: “Because of the timing of the Fed rate hikes in mid-September, most of their impact will be realized in the 4th quarter.” — Paul J. Brody, Chief Financial Officer, Treasurer, Secretary · 2026-10-15 The sensitivity framing (~$83M of annual NII per 25bp U.S. move, $35M for non-USD) now reads as a tailwind rather than a cushion, and the borrowing book that feeds it is white-hot — “The primary driver was the size of the increase of the balances themselves, up 47% on the year and another 8% on the quarter.” — Paul J. Brody, Chief Financial Officer, Treasurer, Secretary · 2026-10-15 Divergent Central Banks cutting one way and hiking the other is, for once, a help.
