XTB S.A. is a Warsaw-based brokerage firm that provides products, services, and technology solutions for trading various financial instruments, including foreign exchange and contracts for difference. Founded in 2002 by Jakub Zabłocki, it is one of the world’s largest publicly traded FX & CFD brokers, employing around 1,000 staff members and serving 1.36 million clients globally by the end of 2024. XTB maintains offices in 13 countries and is regulated by the Polish Financial Supervision Authority, the Financial Conduct Authority, and the Cyprus Securities and Exchange Commission, among others. It has been listed on the Warsaw Stock Exchange since 2016. As of late 2024, XTB reported 658,500 active traders. Its annual revenue for 2024 reached PLN 1.87 billion, with commodity-based CFDs accounting for 48 percent of that total. The firm has faced multiple regulatory actions: in 2018, the KNF imposed a PLN 9.9 million fine—its second-largest penalty on record—citing "asymmetric price slippage." In 2021, France's Financial Markets Authority fined XTB for several regulatory breaches, and in 2023, a Brazilian regulator barred the broker from operating without a local license. Wikipedia
