MarketAxess Announces Trading Volume Statistics for September and Third Quarter 2025

· Issued by Marketaxess Holdings, Inc. via Business Wire

NEW YORK--(BUSINESS WIRE)-- 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 September 2025 and the third quarter ended September 30, 2025.1

Chris Concannon, CEO of MarketAxess, commented:

“Despite historic levels of new issuance in U.S. credit in September, which dampened our estimated market share in the month, we set a new record for U.S. credit portfolio trading ADV and market share. We also generated strong year-over-year growth in ADV in our combined emerging markets and eurobonds product areas of 9% in September, driven in part by record levels of emerging markets hard currency trading ADV, which increased 13%. Additionally, in September, we set a new record for our single highest credit trading volume day ever on the platform on the last trading day of the month. With our new initiatives in the client-initiated channel, block trading ADV in emerging markets and eurobonds increased 35% and 41%, respectively. In the portfolio trading channel, we delivered record U.S. high-yield market share of 25.9%. The growth in these new initiatives is being driven by the technology modernization that we are delivering across U.S. credit, eurobonds and emerging markets.”

Select Third Quarter 2025 Highlights* (See tables 1-1C and table 2)

We continued to show solid progress year-over-year with our new initiatives across the client-initiated, portfolio trading and dealer-initiated channels.

Client-Initiated Channel

  • 10% growth in block trading ADV, including 20% growth in emerging markets and 58% growth in eurobonds block trading ADV. — Cumulative trading volume from our targeted block trading solution is now approximately $10.1 billion.

Portfolio Trading Channel

  • 20% increase in total portfolio trading ADV to $1.4 billion, with record U.S. high-yield portfolio trading ADV of $341 million. These results for the quarter were driven by strong monthly total portfolio trading ADV in September 2025 of $1.7 billion.
  • Our third quarter estimated market share of U.S. credit portfolio trading was 19.1%, compared to 20.0% in the prior year, but up from 17.5% in second quarter 2025.
  • Our U.S. credit portfolio trading market share in September hit a new monthly record of 22.5%. This strong performance was in part driven by record U.S. high-yield market share of 25.9%, representing an increase of approximately 730 basis points year-over-year.

Dealer-Initiated Channel

  • Dealer-initiated ADV increased 18% to $1.5 billion.

Third Quarter 2025 Variable Transaction Fees Per Million1 (See table 1D)

  • The decline in total credit FPM compared to the prior year was driven principally by protocol mix. The increase compared to 2Q25 was driven principally by product mix, specifically the higher duration of bonds traded in U.S. high-grade on an increase in the weighted average years to maturity traded.
  • Total rates FPM was in line with the prior year. The quarter-over-quarter increase was driven by the impact of product mix.

*All comparisons versus third quarter 2024 unless noted.
