Nordic Capital has agreed to acquire a majority stake in TradingHub, a London-based provider of trade surveillance technology for global financial institutions. The deal, expected to close in the second quarter of 2026, will see existing investor Summit Partners retain a minority position alongside co-founder Neil Walker.

TradingHub processes over four billion trades and orders daily, serving major investment banks, asset managers, hedge funds, and brokerage firms. Founded in 2010, the company operates from offices in London, Toronto, Singapore, and Sydney, building technology that helps detect potential market abuse across financial markets.

The investment will accelerate TradingHub's global expansion and platform development. The company plans to strengthen capabilities across asset classes, including equities, while expanding into new markets and geographies. TradingHub's technology addresses growing concerns about market manipulation becoming increasingly complex and cross-product.
