IG Group Shares Plunge Over 25% After Trading Giant Slashes 2026 Revenue Outlook

Shares in IG Group plunged more than 25% on Friday after the FTSE 100 online trading platform sharply cut its 2026 revenue forecast, putting the stock on course for its worst single day since December 2016, according to Reuters.

The London-based company said in an unscheduled trading update that it now expects 2026 revenue growth to land only in a mid-single-digit percentage range year on year, down from the 10 to 15 percent growth it had guided toward in May. Its shares sank as much as 27% to 936.78 pence in morning trading — their lowest level since April 2025 — before trimming some losses, the Wall Street Journal reported.

IG blamed a tough third quarter in its core over-the-counter derivatives business. Revenue for the three months to September is expected to fall about 14% year on year to around £240 million ($317 million), as revenue retention from the OTC book dropped to about 70%, below the 80% average the firm had recorded since it overhauled its market-making approach, according to Reuters.

Chief executive Breon Corcoran said customer activity remained healthy — first trades and active customers both grew strongly — and that he remained confident of meeting the company’s medium-term guidance, though he admitted third-quarter revenue suffered in “less supportive” market conditions.

The sell-off also dragged down rivals, with shares in Plus500 and CMC Markets falling between 7% and 10%. IG expects about £30 million in one-off costs in 2026 from its redomicile to Jersey and a restructuring programme, and warned its earnings margin would slip to the low-40s percent range, down from 47.3% in 2025, Morningstar reported.
