MarketAxess Announces Trading Volume Statistics for May 2026

NEW YORK--(BUSINESS WIRE)--Jun. 4, 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 May 2026.1

Select May 2026 Highlights* (See tables 1-1C and table 2)

Trading volumes across most products, as well as U.S. high-grade estimated market share, rebounded in May from April levels. U.S. high-grade estimated market share increasedapproximately 100 basis points to 17.8%, driven by improved estimated market share in the client-initiated channel on our platform.

The Company estimates that duplicate trade reports inflated U.S. high-grade TRACE volumes by up to 8% in May 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 160basis points higher, or approximately 19.5%, in May 2026.

With the improvement in estimated market share in the client-initiated channel in U.S. high-gradecompared to April, we also continued to make progress with block trading, portfolio trading and dealer-initiated protocols across the platform. Growth in these protocols was a key driver of the month-over-month decline in total credit FPM.

Client-Initiated Channel

  • 17% increase in block trading ADV to $6.0 billion, with U.S. credit block ADV of $3.5 billion, up 14%,compared to a 16% increase in TRACE U.S. credit block ADV. Emerging markets block ADV of $2.0 billionincreased 35% and eurobonds block ADV of $549 million decreased 14%.

Portfolio Trading Channel

  • 47% increase in total portfolio trading ADV to $2.1 billion, including record U.S. high-grade ADV of $1.4 billion up 68%,U.S. high-yield ADV of $412 million,up 172% andemerging markets ADV of $160 million, up 105%.
  • 22.0% estimated market share of U.S. credit portfolio trading,compared to 16.8% in the prior year.

Dealer-Initiated Channel

  • Dealer-initiated ADV of $1.8 billionwas down slightly from the prior year. Record levels of emerging markets ADV (+35%) andeurobonds ADV (+35%) wereoffset by declines in U.S. high-grade ADV.Total Mid-X trading volume wasa record $7.0 billion, representing an increase of 119%.

May 2026 Variable Transaction Fees Per Million1 (See table 1D)

  • The year-over-year and month-over-month declines in total credit FPM were driven by product and protocol mix.
  • The year-over-year and month-over-month increases in total rates FPM were driven by the impact of protocolmix.

*All comparisons versus May 2025 unless noted. Client-initiated block trading ADV may include some portfolio trading activity.

The FPM for total credit and total rates for May 2026 is preliminary and may be revised in subsequent updates and public filings. 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 May 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 May 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.
