Why IG Group Is in Focus Today

IG Group Holdings plc (LSE:IGG), the online trading platform best known for contracts for difference, spread betting and share dealing, is drawing attention on the FTSE 100 as global markets reacted sharply to the US midterm elections. On Wednesday, 4 November 2026, the FTSE 100 rose 1.8%, the Dow Jones gained about 2.5% around the London close, oil fell below $100 a barrel and gold rose above $4,000 an ounce. Such large moves across asset classes typically increase client trading activity, which is the main driver of IG's revenue.

The elections have also put prediction markets in the spotlight. Platforms that allow users to trade on the outcome of events, including elections, have grown rapidly in the United States, and IG's planned Acquisition of Underdog is designed to give it a foothold in this market.

The Underdog Deal

Earlier in 2026, IG announced that it had agreed to acquire Underdog, a US daily fantasy sports and prediction markets operator, for up to $1.3 billion. The deal represents a major strategic move into the US consumer market. Investors reacted negatively, and the shares tumbled after the announcement, with concerns about the price, regulatory risk, integration and whether the Business fits with IG's core trading franchise. The shares fell again in subsequent weeks, highlighting continued investor caution.

Management argues that the US offers a large growth opportunity and that prediction markets and fantasy sports can attract a younger audience that could later use IG's Investment and trading products. Regulation of prediction markets in the US is evolving, with federal and state authorities taking different approaches.

The Core Business

IG generates Revenue mainly from client trading in leveraged products such as contracts for difference and spread bets, as well as from Options and futures through its US business tastytrade and from share dealing.

In recent years, the company has focused on diversifying its revenue and attracting new clients through lower-cost investment products.

Market Context on 4 November

Wednesday's moves offered the kind of volatility that tends to support trading volumes. The decisive US election result, swings in oil and gold, and expectations for a Bank of England rate rise on 5 November created opportunities for active traders. A UK rate rise would also lift interest earned on client cash balances. At the same time, a calmer market environment later in the year could reduce activity.
