MarketAxess Announces Trading Volume Statistics for April 2026

MarketAxess Announces Trading Volume Statistics for April 2026 May 6, 2026 MarketAxess Holdings Inc. (Nasdaq: MKTX), the operator of a leading electronic trading platform for fixed-income securities, today announced trading volume and preliminary variable transaction fees per million (“FPM”) for April 2026.1 Select April 2026 Highlights* (See tables 1-1C and table 2) Elevated market volatility in April of last year, combined with a return to low volatility and tighter credit spreads in April 2026, were key drivers of the year-over-year declines in trading volumes. The Company estimates that duplicate trade reports inflated U.S. high-grade TRACE volumes by up to 8% in April 2026. Adjusting for these duplicates, consistent with FINRA’s recent proposal to suppress duplicate reporting, we believe our estimated U.S. high-grade market share would have been approximately 160 basis points higher in April 2026. April’s strong new issuance calendar further reduced our estimated U.S. high-grade market share. Despite the challenging April, we continued to make progress with our new initiatives across the client-initiated, portfolio trading and dealer-initiated channels. Client-Initiated Channel 12% decline in block trading ADV to $5.1 billion, with U.S. credit block ADV of $3.0 billion down 21%, emerging markets block ADV of $1.8 billion up 13% and eurobonds block ADV of $376 million down 24%. Portfolio Trading Channel 3% decline in total portfolio trading ADV to $1.7 billion, including U.S. high-grade ADV of $1.0 billion down 14%, U.S. high-yield ADV of $501 million up 52%, emerging markets ADV of $110 million up 33%, and eurobonds ADV of $174 million down 34%.Our estimated market share of U.S. credit portfolio trading was 20.2%, compared to 19.6% in the prior year. Dealer-Initiated Channel Dealer-initiated ADV of $1.7 billion declined 11% compared to the prior year. Total Mid-X trading volume was $6.7 billion, the second highest month since the launch in U.S. credit, representing an increase of 156%. April 2026 Variable Transaction Fees Per Million1 (See table 1D) The year-over-year decline in total credit FPM was driven by product and protocol mix, partially offset by the higher duration of bonds traded in U.S. high-grade. The month-over-month increase was driven by product mix.The year-over-year increase in total rates FPM was driven by the impact of protocolmix. The month-over-month decrease in total rates FPM was driven by client mix. *All comparisons versus April 2025 unless noted.

The Company undertakes no obligation to update any fee information in future press releases. 2 Effective with the release of our January 2026 trading volume statistics, the Company revised certain aspects of its reporting methodology for estimated market share to provide a more comprehensive view of platform activity and enhance comparability with industry peers. The Company now highlights estimated market share for U.S. high-grade and U.S. high-yield on an all-in basis, which includes single-dealer portfolio trading activity, and the Company will no longer report estimated market share on an "excluding single-dealer portfolio trading" basis. Single-dealer portfolio trading activity continues to be excluded from the “Total MKTX Credit ADV (excl. SD PT)” line in Table 1, the “Total Credit” FPM calculation in Table 1D and the “Total Credit Trading” line in Table 2. “SD PT” is defined as single-dealer portfolio trades. As used in Table 1 to highlight the effect of single dealer portfolio trading on U.S. high-grade and U.S. high yield ADVs, “SD PT” means single-dealer portfolio trades. 3 “Other Credit Products” includes municipal bonds, leveraged loans, convertible bonds and structured products. 4 The number of U.S. trading days is based on the SIFMA holiday recommendation calendar and the number of U.K. trading days is based primarily on the U.K. Bank holiday schedule. 5 The Company estimates that duplicate reports increased reported monthly TRACE volumes by up to 8% of U.S. high-grade TRACE in April 2026. Adjusting for these duplicates, consistent with FINRA’s recent proposal to suppress duplicate reporting, the Company believes its estimated U.S. high-grade market share would have been approximately 160 basis points higher in April 2026. General Notes Regarding the Data Presented Reported MarketAxess volume in all product categories includes only fully electronic trading volume. MarketAxess trading volumes and the Financial Industry Regulatory Authority (“FINRA”) Trade Reporting and Compliance Engine (“TRACE”) reported volumes are available on the Company’s website at investor.marketaxess.com/volume.
