X Open Hub Limited, trading as XTB Institutional, is the B2B institutional division of the publicly listed fintech XTB S.A. Group. Founded in 2012 and headquartered in Warsaw, Poland, the firm supplies deep multi-asset liquidity, prime-of-prime execution, and trading infrastructure exclusively to professional counterparties such as banks, brokers, and fintech platforms. Its wholesale offering spans over 5,000 OTC instruments including FX pairs, indices, commodities, metals, equities, ETFs, and cryptocurrency CFDs. The company is regulated by the UK Financial Conduct Authority (FCA) and benefits from the broader XTB Group's licensing in multiple jurisdictions, including Poland, Cyprus, Dubai, South Africa, and Indonesia. A key differentiator is its open API (xAPI) for low-latency trading applications and a proprietary HTML5 platform (XOH Trader) suitable for white-labelling. In 2025, the division rebranded under the name XTB Institutional to consolidate all B2B operations, while X Open Hub remains the legal entity. With a team of around 200 professionals, the company continues to expand into emerging markets, most recently securing an Indonesian licence through XTB's local subsidiary.
Detailed Review
Business Model and Client Base
X Open Hub operates strictly on a wholesale basis, targeting professional counterparties only. It does not serve retail investors directly; retail clients access its liquidity exclusively through partner brokers. The firm's value proposition centres on multi-venue liquidity aggregation, ultra-fast execution via colocated servers in major data centres, and flexible integration options supporting FIX 4.3/4.4, GUI-based connection, and the proprietary xAPI. A smart B-book execution model and transparent pricing with spread rebates and book-share arrangements are hallmarks of the service.
Technology and Infrastructure
The company offers the XOH Trader, a next-generation HTML5 trading platform available as web and mobile apps, designed for white-labelling by partner brokers. The xAPI provides the lowest latency and highest throughput among competing APIs, enabling clients to build custom trading applications for desktop and server environments. The back-office system delivers real-time exposure monitoring, low-margin notifications, and complex reporting. Server colocation in global data centres ensures consistent low-latency execution.
Licensing and Regulation
X Open Hub Limited is authorised by the UK FCA (FRN 522157). The wider XTB Group holds licences from KNF (Poland), CySEC (Cyprus), DFSA (Dubai), FSCA (South Africa), FSC (Mauritius), FSA (Seychelles), SCA (UAE), with EU passporting to over 25 countries. In 2025 the group obtained an Indonesian PALN licence via XTB Indonesia Berjangka, allowing X Open Hub to offer its services to institutional clients in Indonesia for the first time.
Recent Developments
In 2025, XTB Group announced the consolidation of its B2B division under the name XTB Institutional while X Open Hub remains the legal entity. Product expansion now includes over 5,000 instruments, with a growing range of crypto CFDs. The firm signed a strategic cooperation partnership with Hong Kong-based fintech OTSO Fintech, and has continued alliances with prime brokers and technology vendors. Regional growth focuses on the Middle East and Africa, with CEO Michał Copiuk discussing MEA market potential in an exclusive interview with Al-Bayan Magazine.
Reputation and Market Position
On platforms such as LiquidityFinder and Forex Peace Army, X Open Hub receives consistently positive marks for execution quality and regulatory transparency, though the lack of retail-facing reviews limits public feedback volume. The firm is recognised as a reliable prime-of-prime partner by industry analysts.
