Reported July 21, 2026

30-second summary

30-second take: Revenue grew 28% YoY to $1.90B, beating consensus of $1.78B by 6.5%, while adjusted EPS of $0.69 topped the $0.63 estimate by 9.5%. Pretax margin held at 77% — snapping back to the top of the historical 75-77% band that Q1 reset to, and up +200bps YoY — and every major KPI accelerated: customer accounts +34% YoY to 5.19M (~430k net adds QoQ, well above Q1's ~350k pace), margin loans +26% QoQ to a new record $108.5B (+67% YoY), and NIM ticked up 5bps sequentially to 1.93%. The bull case built across the prior four quarters — automation moat, rate-independent commission growth, accelerating account adds — is compounding rather than plateauing.

Management tone

Q3 FY2025 explicit acceleration → Q4 FY2025 execution over rhetoric → Q1 FY2026 offensive posture on growth investments → Q2 FY2026 structural inflection.

Account growth reframed from a "20% baseline that we sandbag past" to a structural 30%+ new normal. Two quarters ago management was still hedging on whether the 30%+ pace could sustain; last quarter Peterffy went "hell-bent" on marketing to accelerate it further. This quarter Thomas addressed the anchoring directly: "It was only once when I said that we will grow up 30% and immediately the growth rate went down to 20. And then everybody said 20, 20, 20. And ever since that time, we have been over 30." The Q2 net adds of ~430k vs Q1's ~350k substantiate the framing — this is management publicly retiring the 20% baseline that analysts still model against.

AI roadmap advances from "operating plumbing" (Q1) to "fully autonomous agentic trading with guardrails" (Q2). In Q1 the framing was that AI had moved from research tool to plumbing installed across the stack; this quarter Milan extended the arc further: "We are going to be offering at some point fully autonomous agentic trading, but we're going to be very careful about the type of guardrails that will be available for our clients." This is the first time IBKR has publicly committed — even qualitatively — to autonomous execution as a product direction, not just AI-assisted workflow. Across three quarters the frame has moved chatbot → operating layer → autonomous agent.

Marketing-yield conviction hardens from "hell-bent but slow" to "structurally improving." Q1's "hell-bent" language was paired with Peterffy admitting the ramp was "going very slowly." This quarter Thomas gave the substance the Q1 tone lacked: when pressed on whether marketing yield had improved, he first said "roughly the same" but then affirmed that the new CMO strategy gives him "increased confidence around the ability to deliver better than 20% account growth." The Q2 net-add step-up (~430k vs ~350k) is the operational proof point. This is the first quarter where the marketing pivot shows up in the KPIs, not just the rhetoric.

Risk posture on margin loans shifts from Q3 FY2025's "sudden dislocation" watchword to explicit endorsement. Galik had flagged in Q3 FY2025 that margin loan expansion was healthy but could reverse on a dislocation. This quarter, with margin loans at a fresh $108.5B record (+26% QoQ, +67% YoY), Thomas closed the loop: "We are very cognizant of client risk and margins, and we're continuously monitoring it, and we feel comfortable with the current levels." Three quarters ago this was hedged; now it is endorsed. That is either a confidence signal or a complacency risk, and it merits monitoring given how far the number has run.

Geographic and product expansion pivots from "selective and operationally-driven" to "aggressive multi-region rollout on tight timing." Q4 FY2025 committed Europe crypto for Q1; Q1 FY2026 landed it plus Coinbase derivatives. This quarter the rollout accelerated across five distinct fronts in a single period — Korea (first eBroker), direct SpaceX IPO access, European crypto expansion, IBKR Prediction Markets launch, and CBOE binary options — with Korea framed as "well-timed" and volumes going "straight up." The register has shifted from measured product cadence to compressed multi-front execution.

Recurring themes management leaned on this quarter:

Structural acceleration in account growth beyond historical 20% baselineAI integration as gateway to autonomous trading ecosystem with guardrailsGeographic and product expansion capturing regulatory/market timing windowsMargin balance growth as indicator of healthy risk-on client behavior, not excessSecurities lending upside from hard-to-borrow names (SpaceX, Korean semiconductors) driving NIM expansionCapital deployment: $10.3B excess capital accumulating, acquisitions remain selective

Risks management surfaced:

Margin loan growth acceleration—though management expressed comfort, external volatility could reverse trendRegulatory clampdown risk (referenced Tiger/Futu mainland China situation, but management claims compliance advantage)AI chatbot runaway risk—reason for human-in-loop guardrails on autonomous trading not yet liveSecurities lending revenue volatility tied to rotating hard-to-borrow names and temporary market dislocationsInterest rate direction uncertainty—25bp moves create ±$81M annual NII sensitivity; Fed rate already fell 70bp YoY

Answers to last quarter's watch list

Pretax margin stabilising in the 75-77% band or breaking lower. Resolved positively. Q2 held at 77% — flat QoQ, +200bps YoY, at the top of the historical band. Sub-75% did not materialise; the Q1 QoQ compression is now clearly reversion to trend, not the start of a slide. Status: Resolved positively
SEC fee impact as a named Q2 cost line. Resolved. Paul Brody quantified the reinitiation of SEC Section 31 fees explicitly: $34 million this quarter, a $19 million YoY increase, with the pass-through mechanic confirmed ("largely passed through, these fees increase both our commission revenue and execution costs and therefore do not impact profits"). Ex-SEC, execution/clearing costs were $108M vs $101M — a clean 7% underlying growth print. Status: Resolved positively
ForecastX Q1 pair volume disclosure. No hard pair-volume figure was disclosed this quarter either. Nancy's prepared remarks referenced the launch of IBKR Prediction Markets as one of five product introductions but did not update the 286M Q4 anchor. Two consecutive quarters of silence on a metric IBKR voluntarily disclosed in Q4 is the signal the Q1 watch flagged as material. Status: Resolved negatively
Marketing spend ramp visible in operating expenses. Resolved positively on the KPI side. Q2 net account adds stepped up to ~430k from Q1's ~350k — a sequential acceleration that maps to Thomas's affirmation of "increased confidence around the ability to deliver better than 20% account growth." Whether the G&A/advertising line ratchets up commensurately requires the detailed expense breakout, but the conversion side of the tone-vs-substance test cleared. Status: Resolved positively
Bank charter status disclosure cadence. Resolved positively. Management disclosed that IBKR received preliminary conditional approval from the OCC on its National Trust Bank charter application — the enabling milestone for directly custodying mutual fund and ETF customer assets — and reiterated the year-end 2026 operational target ("We plan to have the necessary work completed and have it operational by year end"). The Q1 silence has broken with a concrete regulatory milestone rather than more vague timeline language. Status: Resolved positively
Execution, clearing & distribution fees stabilising. Resolved positively. The line reversed from -12% YoY in Q1 to +22% YoY at $142M in Q2 (+34% QoQ). The Q1 soft data point cleared decisively, driven primarily by the $19M SEC fee pass-through; underlying ex-SEC growth was 7%. Status: Resolved positively

What to watch into next quarter

Margin loans at $108.5B (+67% YoY) — sustainability or reversal signal. Watch whether Q3 sustains above $100B or contracts materially — a $10B+ pullback would confirm this was a Q2-specific risk-on spike, not a new operating level. This is the cleanest leading indicator of client-risk-appetite direction.

Pretax margin third consecutive quarter at 77% or a break higher. Two quarters at 77% converts the Q1 reset from anomaly to reasserted band. Watch whether Q3 stays at 77% (structural floor confirmed) or breaks toward 78%+ (the 79% Q3/Q4 FY2025 prints may have been directional, not one-off). Sub-75% still remains the bear signal.

Bank charter — from conditional approval to operational go-live. With OCC preliminary conditional approval now in hand and year-end 2026 reiterated as the operational date, the next test is execution against that timeline. Watch Q3 for concrete progress markers — full charter conversion, first custody flows, or any timeline slip. A slip here now matters more, not less, given management has committed publicly to the year-end date.

ForecastX / Prediction Markets pair volume re-engagement. Silence for a third consecutive quarter on a metric IBKR voluntarily disclosed in Q4 FY2025 would be a confirmed signal that growth normalised sharply or that the product isn't scaling to management's original expectation. Watch whether the Q3 release re-quantifies.

Net account adds sustaining above 400k. Q2's ~430k is the highest quarterly figure IBKR has printed. Watch whether Q3 clears 400k — that would validate the marketing-yield structural improvement thesis and the 30%+ growth "new normal" framing.

NIM trajectory as the Fed cut cycle continues. Q2 NIM ticked up 5bps QoQ to 1.93% despite the rate backdrop. Watch whether Q3 holds above 1.90% — sustained flat-to-up NIM against continued Fed easing would be strong evidence that balance-growth is structurally outrunning rate-pressure.
