Bullish

Interactive Brokers

Reported January 20, 2026

30-second summary

30-second take: Revenue grew 18.5% YoY to $1.64B with adjusted pretax margin holding at 79% — the Q3 step-up is now a two-quarter pattern, not a one-off. Customer margin loans hit a new all-time high of $90.2B, +40% YoY (and +17% QoQ from Q3's $77.3B), and the bank charter application is officially filed with the OCC and expected operational by year-end 2026. NII grew 20% YoY despite the Fed cut cycle, validating last quarter's "balance growth offsets rate pressure" thesis.

Management tone

Q4 FY2024 anchor → Q1 FY2025 measured → Q2 FY2025 chairman conviction → Q3 FY2025 explicit acceleration → Q4 FY2025 execution over rhetoric.

Bank charter shifts from aspiration to filed application with a date. Across the prior briefs, the bank charter was a forward-looking ambition without timeline. This quarter, in response to Brennan Hawkin (BMO), management confirmed the OCC application is officially filed and operational by year-end 2026, with the trust charter explicitly enabling custody of mutual funds and ETFs that broker-dealer regulations currently prohibit. This is the single largest structural disclosure of the year — a concrete expansion of the addressable asset base, dated.

Crypto framing decelerates from "core strategic priority" to "currently immaterial." Q2 FY2025 elevated crypto to a strategic priority; Q3 FY2025 gave it dated milestones (stablecoin deposits end of October, asset transfers by year-end, staking when ready). This quarter Galik told Craig Siegenthaler (BofA) plainly that "crypto revenues currently small relative to overall company" and "iBrokers have not requested crypto access." The Europe launch is still on track for Q1 FY2026, but the rhetorical heat is gone. Management is signalling that crypto is a checkbox in the offering, not a near-term P&L driver.

Forward conviction language quieter than Q3. Q3 closed with "even more to come in 2026" and the chairman publicly anchoring a 2-3 year rally view. This quarter offered no equivalent forward-looking statement. Notably, however, the quantitative rate-sensitivity anchors were refreshed: Brody restated the 25bp USD Fed funds sensitivity at -$77M annual NII and added a -$31M figure for a 25bp non-USD cut. Two interpretations on the conviction softening: either management is genuinely uncertain about 2026 macro, or they have learned from Q2-Q3 that explicit conviction language gets quoted back at them when surprises hit. Given the bank charter filing and account growth posture, the second reading is more consistent with the evidence.

ForecastX growth disclosure is unusually specific for IBKR. Asked by Patrick Moley (Piper) about prediction markets, management volunteered that ForecastX traded 286M pairs in Q4 vs 15M in Q3 — a 19x sequential jump — with 10,000+ instruments listed and four members quoting into the exchange. For a firm that has historically been measured about new-product disclosure, putting hard numbers on a non-core product is itself a tone shift. They are confident enough in ForecastX to brag about it.

Universal-segment growth language replaces specific cohort callouts. Asked by Dan Fannin (Jefferies) where account growth is coming from, Galik said success is "universal across all segments — large/small accounts, active/passive, retail/professional/institutional." Compare to Q2 FY2025 where management specifically called out introducing-broker wins and competitor defections, or Q3 where Asia overnight trading was highlighted. The current posture is closer to "we are no longer growth-constrained by mix" — which is a confidence statement, but in a quieter register than Peterffy's CNBC commentary in Q2.

Q&A highlights

Brennan Hawkin · BMO Capital Markets

Asked about customer credit balance yields not declining as much as expected despite rate cuts, and requested an update on the bank charter application status and timeline.

Management explained repricing lag on asset side due to short duration strategy. On bank charter: officially filed application with OCC, expects operational status by end of 2025. Trust charter will allow custody of mutual funds and ETFs, which broker-dealer regulations currently prohibit.

Craig Siegenthaler · Bank of America

Asked about appetite for cryptocurrency adoption among retail and iBroker channels, and pressed on timeline for maintaining 30%+ account growth.

Crypto revenues currently small relative to overall company; most active crypto traders already trading before IBKR entry. iBrokers have not requested crypto access. Pricing is competitive. Europe launch expected this quarter. On growth: expects no slowdown if company maintains current execution level.

Patrick Moley · Piper Sandler

Asked about regulatory uncertainty around sports prediction contracts and whether IBKR would offer them; inquired about M&A appetite and excess cash deployment.

Noted Massachusetts ruling against Kalshi but stated regulatory outcome uncertain. IBKR does not depend on sports; believes prediction contracts have broad applicability. On M&A: will not acquire sports betting firms; ForecastX platform growing organically with 10,000+ instruments and increased volumes.

James Yarrow · Goldman Sachs

Asked about European banking license aspirations and timeline; inquired about institutional adoption of prediction markets and client development strategy.

European banking license not urgent; when pursued, likely in Ireland given existing regulatory relationships. Temperature contracts are most frequently traded; working on connecting them with electricity and natural gas contracts to attract utilities/institutional users.

Dan Fannin · Jefferies

Asked about expense growth outlook given AI initiatives and where account growth is coming from by segment.

Expense growth expected consistent with last few years; headcount grew 6% in 2025, compensation up 10%. AI initiatives may affect future growth rate. Seeing universal success across all segments—large/small accounts, active/passive, retail/professional/institutional.

Answers to last quarter's watch list

NII trajectory under a Fed cut cycle. Resolved positively. Q4 NII came in at $966M, +20% YoY — well above the $900M threshold, and effectively flat with Q3's $967M despite NIM compressing 14bps QoQ to 2.02%. Balance sheet growth (margin loans +40% YoY to $90.2B, credit balances $160.1B) absorbed the rate pressure. The refreshed sensitivity disclosure (-$77M per 25bp USD cut, -$31M per 25bp non-USD cut) confirms scale is offsetting per-bp impact. Status: Resolved positively
Pretax margin holding at 79% or reverting. Resolved positively. Adjusted pretax margin held at 79% in Q4, matching Q3 exactly. Full-year margin printed 77%. Two consecutive quarters at 79% converts the Q3 step-up from anomaly to new floor — exactly what bulls needed to see. Status: Resolved positively
Stablecoin deposits live end of October and crypto asset transfers by year-end. Not resolved cleanly. Management did not confirm whether the October stablecoin go-live or year-end asset transfers milestones were hit; Galik instead said asset transfer capability is "being developed" and disclosed that Europe crypto launch is the Q1 FY2026 priority. The Q3 commitments slipped from the disclosure framework. Status: Not resolved
Margin loans at all-time high — sustainability vs reversal signal. Resolved positively. $90.2B is a new all-time high, +40% YoY (and +17% QoQ above Q3's record $77.3B). Client risk appetite intensified rather than reverted. The "sudden dislocation" Galik flagged in Q3 did not arrive. Status: Resolved positively
Other fees & services declining 8% YoY. Resolved positively. Other fees & services swung from -8% YoY in Q3 to +5% YoY in Q4 ($85M). The one soft data point cleared. Status: Resolved positively
Customer account net adds in Q4 FY2025. Resolved positively. Total customer accounts reached 4.40M at year-end vs 4.127M at Q3 end — implying ~270k Q4 net adds, sustaining the +32% YoY pace vs 3.337M prior year. The acceleration narrative held through the harder Q4 comparison. Status: Resolved positively

What to watch into next quarter

Bank charter operational milestone. Management told BMO the OCC application is filed and operational status is expected by year-end 2026. Watch for confirmation that the trust charter is operational and whether IBKR begins disclosing mutual fund / ETF custody balances as a new metric. This is the single largest structural disclosure of the year.

Europe crypto launch in Q1 FY2026. Galik explicitly committed to a current-quarter launch in response to BofA. Watch whether it lands on time and whether IBKR discloses any revenue or volume KPIs for crypto, given Q4's "immaterial" framing.

Margin loan trajectory from $90.2B base. +40% YoY from a record base is unusual. Watch whether Q1 sustains above $85B or contracts — historically Q1 sees seasonal mix shifts and any pullback would signal the Q4 surge was leverage-cycle peaking, not a new normal.

Pretax margin third consecutive quarter at 79%. Two quarters at 79% is a pattern; three makes it the new floor. Watch whether Q1 sustains or whether the historical 75-77% range reasserts.

ForecastX volume continuation from 286M pairs. 19x sequential growth from 15M to 286M is the kind of curve that either compounds or normalises sharply. Watch whether Q1 prints above 300M pairs — that would validate management's organic-growth-no-M&A stance on prediction markets.

Rate sensitivity trajectory. With the $77M/25bp USD and $31M/25bp non-USD anchors now restated off a December 31 starting point and a 3.64% Fed funds effective rate, watch whether continued balance-sheet growth visibly compresses these sensitivities in Q1 disclosure — the cleanest forward read on whether scale is outrunning rate pressure.
