Capital Group Takes 5% Stake in IG Group, Following Similar Plus500 Investment

US asset management giant Capital Group has acquired a significant 5% stake in IG Group, marking its second major investment in a London-listed retail brokerage within six months, following a similar move into Plus500 last June.

In a regulatory filing submitted to the London Stock Exchange, Capital Group disclosed that its voting interest in IG Group had crossed the 5% threshold, triggering a mandatory notification under UK transparency rules.

Capital Group Crosses the 5% Threshold

The holding represents roughly one-twentieth of IG Group’s voting share capital, based on the company’s most recent total voting rights disclosure. According to the RNS filing published on Monday, Capital Group controls 17,157,806 voting rights in the broker.

As of 31 December 2025, IG Group reported 361,557,868 ordinary shares in issue, including 21,548,034 treasury shares, leaving 340,009,834 shares with voting rights. Based on this figure and a current share price of approximately $18.60, Capital Group’s 5% position equates to around 17 million shares, with an estimated market value of $316 million.

Previous Plus500 Investment

The IG Group stake follows Capital Group’s move into Plus500, where it acquired a 5.44% stake in June 2025, according to a separate London Stock Exchange filing. The disclosure placed the US fund manager among the broker’s largest shareholders.

While the investment’s exact value was not officially disclosed, the 3,917,567 Plus500 shares held by Capital Group are currently valued at approximately £133.1 million (around $181 million), based on prevailing market prices.

IG Group Delivers Strong Quarterly Performance

The disclosure comes as IG Group reported robust financial results for the three months ended November, with growth recorded across its core business lines, including CFDs, stock trading, and broader retail activity.

Net trading revenue climbed to £271 million, representing an increase of nearly 30% year-on-year. The United States continued to stand out as the company’s fastest-growing market, where its subsidiary tastytrade generated more than $65 million in revenue during the period.
