About
MarketAxess Holdings Inc. is a New York City-based electronic fixed income trading platform — publicly traded on the NASDAQ (NASDAQ: MKTX) as an S&P 500 Financials component — operating the leading electronic trading marketplace for US investment-grade corporate bonds, US high-yield bonds, emerging market bonds, municipal bonds, and US Treasury securities through approximately 850 employees globally. In fiscal year 2024, MarketAxess reported revenues of $763 million with record trading volumes in US investment-grade bonds and emerging market credit, as the multi-year electronification trend in bond markets continued to shift institutional fixed income trading from voice broker-dealer phone execution to electronic all-to-all trading on MarketAxess's Open Trading marketplace. CEO Chris Concannon (joined 2023, formerly Cboe Global Markets president) leads MarketAxess's strategy of expanding market share beyond the institutional investment-grade core into rate products (US Treasuries, agency securities), high-yield, and portfolio trading as fixed income electronification accelerates — currently approximately 40% of US investment-grade bonds trade electronically versus 15% in 2015. MarketAxess's Open Trading protocol (anonymous all-to-all price discovery between buy-side, sell-side, and market makers) generated over $2 trillion in liquidity provision in 2024, reducing transaction costs versus bilateral dealer quotes by an average of $0.28 per $100 face value.
