MarketAxess

MarketAxess Holdings Inc. operates leading electronic trading platforms delivering greater trading efficiency, a diversified pool of liquidity and significant cost savings to approximately 2,100 institutional investor and broker-dealer clients across the global fixed-income and other markets. We have built a differentiated market position through our integrated approach to electronic trading, combining diverse trading protocols, automated and algorithmic execution solutions, intelligent data products and analytics and comprehensive post-trade and technology services. The fixed-income markets we focus on remain significantly less electronified than other asset classes, creating significant opportunities for continued growth. We believe our scale, network effects, and product innovation uniquely position us to capture increased trading volumes as the market continues its transition from voice to electronic trading. At the center of our offerings is Open Trading, our award winning all-to-all marketplace, which creates a unique, anonymous liquidity pool that connects market participants across a broad range of fixed-income products. By expanding the number of potential trading counterparties, we believe that Open Trading facilitates price discovery, improves execution quality, and reduces transaction costs for market participants. Institutional investors can also send trading inquiries directly to broker-dealer counterparties on a disclosed basis, while simultaneously accessing the rest of the market on an anonymous basis through Open Trading. We continue to invest in technology innovation. Our next-generation trading platform, MarketAxess X-Pro ('X-Pro'), provides access to multiple trading protocols and workflow tools and integrates our suite of proprietary pre- and post-trade data and analytics tools, powered by our AI-driven pricing engine, CP+, to deliver a seamless user experience. Our automated execution protocols enable clients to pre-define trading parameters and leverage automation to execute transactions seamlessly and efficiently, reducing manual intervention and allowing traders to focus on higher-value opportunities. In 2025, 86.8% of our revenues were derived from commissions for transactions executed on our platforms.
