XTB vs mBank eMakler vs Bossa — Best Broker in Poland 2026

Three Main Players in the Polish Market

Choosing a broker is one of the most important investment decisions — it affects costs, available instruments, and daily usability. In Poland, three platforms dominate retail investing: XTB, mBank eMakler, and Bossa (mBank's brokerage house). Each has its strengths.

Quick Answer

For most retail investors in Poland in 2026, XTB is the cheapest choice — 0 PLN commission on stocks and ETFs up to 100,000 EUR monthly turnover (above: 0.2%, min. 10 EUR), plus fractional shares and up to 4.75% interest on uninvested PLN cash. mBank eMakler (0.29%, min. 5 PLN on GPW, 0 PLN on selected ETFs) suits existing mBank customers wanting bank-integrated investing, while Bossa (0.29% GPW, bonds from 0.15%, futures at 9.90 PLN/contract) gives the broadest Polish-market access for experienced investors. All three are KNF-regulated and support IKE/IKZE.

Side-by-Side Comparison

Which Broker to Choose? Recommendations

Beginner investor (up to 10,000 PLN)

→ XTB. Zero commissions, fractional shares, and an intuitive app. With small amounts, the minimum commission at competitors (5 PLN) eats too much of your investment.

mBank customer seeking convenience

→ mBank eMakler. Banking integration, instant transfers, everything in one app. Zero commissions on selected ETFs are sufficient for building a DCA portfolio.

Experienced GPW investor

→ Bossa. Broadest Polish market access, futures, Catalyst. Advanced analytical tools that competitors lack.

Long-term investor (IKE/IKZE)

→ XTB — zero commissions on ETFs within IKE/IKZE make it the ideal choice for DCA strategies. Alternatively, Bossa if you want to invest in Polish bonds.

FAQ

Can I have accounts at multiple brokers simultaneously?

Yes. There are no restrictions — you can have accounts at XTB, mBank, and Bossa simultaneously. The only limitation applies to IKE and IKZE: you can have only one IKE and one IKZE (but at different brokers). Transferring IKE/IKZE between brokers is possible.

Which broker is the safest?

All three platforms are regulated by KNF (Polish Financial Supervision Authority). Client funds are segregated from broker funds and covered by the KDPW compensation system (up to 20,100 EUR equivalent). XTB, as a publicly listed company, is subject to additional transparency requirements.

Does XTB really charge zero commission?

Yes, up to 100,000 EUR monthly turnover, the commission is 0 PLN on stocks and ETFs. Above this limit, a 0.2% commission applies (min. 10 EUR). For most individual investors, the limit is more than sufficient — 100,000 EUR equals over 430,000 PLN in monthly turnover.

Which broker has the widest access to international markets?

XTB offers global reach across many foreign exchanges with zero commission within the monthly turnover limit, while mBank eMakler and Bossa charge a percentage commission on international orders with higher minimums. For broad Polish-market access (GPW, NewConnect, Catalyst, futures), Bossa is the most comprehensive. The right fit depends on whether you trade mainly foreign or domestic instruments.

Which broker is best for a complete beginner with a small budget?

For small amounts, fractional shares and zero commissions matter most, and XTB supports both, which avoids minimum-commission fees eating into tiny orders. mBank eMakler can be convenient for existing mBank customers thanks to banking integration, though it lacks fractional shares. Some users start with the broker where they already bank to simplify transfers.

Can I open IKE and IKZE accounts at these brokers?

All three — XTB, mBank eMakler, and Bossa — offer IKE and IKZE accounts. You may hold only one IKE and one IKZE at a time, but they can be at different providers, and transfers between providers are generally possible. Available instruments and commission terms differ, so it is worth checking current conditions before opening an account.
