IG Group cuts 2026 revenue growth outlook as third-quarter revenue falls 14%

IG Group lowered its 2026 revenue-growth expectations after weak over-the-counter trading conditions. Third-quarter revenue for the three months ended 30 September is expected at approximately £240 million, down 14% year over year from £280.1 million, signaling a material slowdown in trading activity.

Analysis

IGG’s earnings sensitivity is unusually high because OTC dealing revenue combines client activity, market volatility and net trading revenue; a softer activity backdrop can therefore pressure both top line and operating leverage simultaneously. The market is likely to de-rate the stock until management establishes whether the shortfall reflects transient low-volatility conditions or a loss of wallet share to lower-cost multi-asset platforms such as CMC Markets (CMCX) and Interactive Brokers (IBKR). The critical near-term datapoint is not the revised growth target itself, but whether client acquisition, active-client trends and revenue per client deteriorate together.

Over the next 1-3 months, the downside case is a second guidance reset if volatility remains contained and marketing spend is maintained to defend customer growth; that would imply margin disappointment rather than merely weaker revenue. Conversely, a volatility spike can lift dealing activity quickly, but it is not a clean structural bullish catalyst: elevated volatility also raises client-credit, hedging and regulatory-scrutiny risk. A more durable 6-18 month concern is that retail traders are increasingly migrating toward listed options, ETFs and low-cost execution, where IGG’s OTC economics face secular pricing pressure.

Consensus may over-attribute the weakness to broad market calm. If CMCX reports similarly weak client activity, this is principally a sector-volume problem and IGG’s selloff may become excessive given its capital return capacity; if CMCX holds up, the more damaging interpretation is competitive share loss. IBKR’s monthly account and DART statistics are a useful external read-through, although its US-centric mix limits direct comparability.

Key Decisions for Investors

• Maintain an underweight/short bias in IGG through the next trading update or results cycle; use rallies following volatility-driven revenue optimism to enter. Thesis targets a further earnings-estimate and multiple reset if management signals margin defense through higher acquisition spend; cover if active clients and revenue per active client both stabilize sequentially.
• Express a relative-value trade: short IGG / long IBKR over 3-6 months, sized conservatively for factor and currency mismatch. IBKR is better positioned for structural migration toward listed products and international account growth, while IGG retains greater OTC-revenue cyclicality; invalidate if IGG shows clear client-share gains or IBKR reports a sustained DART decline.
• Use CMCX results and KPI disclosures as a sector diagnostic rather than adding immediately to a directional IGG trade. Broad weakness in active clients and trading revenue would support treating the move as cyclical and reducing the IGG short after an outsized decline; relative resilience at CMCX would reinforce a company-specific competitive-risk short.
• Set a volatility trigger rather than buying IGG solely on valuation: a sustained rise in equity/FX volatility accompanied by sequential improvement in client activity could produce a fast 1-2 quarter earnings rebound. Do not treat volatility alone as confirmation unless revenue per client improves without a disproportionate increase in client-credit provisions or hedging costs.
