Warsaw-listed shares are now open to XTB S.A.'s clients across the European Union without a separate request, the broker and the Warsaw Stock Exchange (GPW) said today (Friday). The two called it a pilot.Until October, only XTB clients in Poland had automatic access to Warsaw-listed instruments on its platform. Retail investors elsewhere needed an extra application first.That route was used by clients in France, the Czech Republic, Slovakia, the UK, Portugal, Romania and Spain, according to the release.The exchange's retail growth has so far been counted in domestic accounts. The Central Securities Depository of Poland (KDPW) counted more than 3 million brokerage accounts at the end of September, 1.285 million of them at XTB, up from 2,856,520 accounts in May, FM Intelligence data show.London's trading industry is coming home!A Polish Firm With a Foreign Client BaseXTB brings the exchange a client base already split between Poland and abroad. Poland generated 54.4% of XTB's 2025 revenue, as FinanceMagnates.com reported when Lynx opened a Warsaw office to compete for Polish savers.XTB says more than 3.2 million people use its investing app. FM Intelligence's FX/CFD heat map shows by country where web traffic to XTB and 97 other retail brokers comes from.One of its biggest sources of new accounts lies outside the bloc the pilot covers first: Indonesia now trails only Poland by new accounts, XTB Chief Executive Omar Arnaout said last week.Filip Kaczmarzyk, a member of XTB's management board, said demand for Polish shares already comes from outside the country."We also see interest in the Polish market from our foreign clients," Kaczmarzyk said, adding that automatic access removes operational barriers for investors abroad.He named CD Projekt, Benefit Systems and LPP as examples of Warsaw-listed companies with business in many international markets.Index Gains Give the Exchange a PitchThe cooperation runs under a GPW program aimed at exchange members that serve foreign retail investors. XTB will also run information and promotional campaigns about the Polish market, a month after it launched what it calls the biggest ad campaign in its history."We want to use their international reach," said Michał Kobza, a member of the Warsaw Stock Exchange's management board, referring to the brokers in the program.Kobza said a larger share of foreign investors would support liquidity and make Warsaw-listed companies better known abroad.The exchange pointed to this year's returns. The WIG20 index has risen more than 34% since January and the mWIG40 30%, against less than 13% for the S&P 500 over the same period.XTB has been listed on the Warsaw exchange since 2016, and last week reported that its third-quarter profit quadrupled from a year earlier. The two gave no date for clients outside the EU.This article was written by Damian Chmiel at www.financemagnates.com.
