XTB endedMarch less than 9,000 accounts shy of a million in its home market, accordingto fresh data from Poland's Central Securities Depository (KDPW), setting upthe Warsaw-listed broker to cross the milestone when April figures arepublished next month.Singapore Summit: Meet the largestAPAC brokers you know (and those you still don't!)The KDPWtally credited XTB with 991,791 accounts with access to the Polish market atthe end of March, an increase of 50,598 from February and 525,452 over the past12 months. With the company adding roughly 55,000 accounts a month over thepast half year, the seven-figure threshold should be cleared well before theApril report lands.The totalPolish brokerage market reached 2,736,531 accounts, up by 60,858 month-on-monthand by 660,154 year-on-year. That means XTB accounted for about 83% of all netnew accounts added to the KDPW system in March, extending a domestic dominancethat has reshaped the Polish broker league table over the past three years.XTB Pulls Further Ahead ofmBank and PKO RivalsThe gapbetween XTB and the rest of the field continues to widen. mBank's brokeragearm, the second-largest player in the KDPW data with 550,244 accounts, added5,522 during the month. State-controlled BM Pekao, ING Bank Śląski, DM BOŚ andBM PKO BP each added fewer than 1,000 accounts. Only mBank and XTB exceeded thefour-figure mark for monthly net additions.The firstquarter as a whole saw Polish brokerages add 201,925 accounts in the KDPWdataset, the strongest start to a year on record. The pace did cool from theDecember and January peak, when Poles rushed to open tax-advantaged IKE andIKZE retirement accounts before the year-end deadline. December alone deliveredroughly 100,000 new accounts and January another 80,600, before February andMarch settled into a similar 60,000-a-month rhythm.XTB hasbeen a primary beneficiary of that retirement-savings push. The broker launched IKZE accounts in mid-2025 to complement its existing IKEproduct, plugging into a segment that government data showed already countedmore than 593,000 IKZE holders nationwide at the end of 2024.Saturated Home MarketForces a Domestic Price WarThe KDPWreport covers all accounts with access to the Polish market regardless ofactivity, and brokerages periodically purge dormant ones, which can causeoccasional dips in the headline figures. A separate dataset published by theWarsaw Stock Exchange tracks active accounts and tends to run lower.The KDPWdata also excludes Revolut, which operates its Polish investing service under aLithuanian license. The fintech disclosed last year that it had signed uparound 590,000 Polish investment customers, a figure that, if it were included in the KDPWrankings, would place it second, ahead of mBank and well clear of every traditional bank-owned broker.Competitionhas only intensified since. German neobroker Trade Republic entered Poland latelast year, and several incumbent brokerages have responded by trimmingcommissions, a domestic price war that Finance Magnates reported on alongside the Decembersurge when theoverall market crossed 2.5 million accounts for the first time. The WarsawStock Exchange's WIG index gained 47% in 2025 and broke through 100,000 pointsfor the first time, a backdrop that has helped pull retail investors off thesidelines.Domestic Engine Powers aGlobal Client BaseFor XTB,the Polish numbers are a partial picture. The KDPW figures only captureaccounts with access to the Polish market, while the broker reports a broaderglobal client base in its quarterly results. The company added 864,000 clients worldwide in2025, more than ithad gathered in its first two decades combined, with Poland generating roughly54% of consolidated revenue.Thatdomestic strength has come at a cost. XTB's2025 net profit fell about 25% to PLN 644.2 million as marketing spendingclimbed nearly 70% to PLN 584.9 million, the company said in its annual report.Chiefexecutive Omar Arnaout has described the spending as a deliberate push toaccelerate client acquisition, and has separately flagged spot crypto trading,due to launch in Cyprus this year, as a way to dilute the group's heavydependence on CFD revenue.This article was written by Damian Chmiel at www.financemagnates.com.
