MarketAxess Announces Trading Volume Statistics for May 2025
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 May 2025. 1
Select May 2025 Highlights* (See tables 1-1C and table 2)
The MarketAxess platform's strong performance persisted in May through moderated levels of volatility, providing our clients with deep liquidity through Open Trading.
We delivered strong progress with our new initiatives across the client-initiated, portfolio trading and dealer-initiated channels that contributed to the strong performance in May.
Client-Initiated
Strong increases in block trading ADV across U.S. credit (+41%), emerging markets (+24%) and eurobonds (+116%). We launched our targeted block trading solution in U.S. credit in mid-May.
Block trading in emerging markets and eurobonds both benefitted from the launch of our targeted block solution in late 2024, which has generated cumulative trading volume of approximately $1.7 billion and $2.7 billion, respectively, since launch.
Clients continued to leverage our algos in U.S. government bond trading, helping to drive a 57% increase in ADV to $28.3 billion with estimated market share of 2.6% in May.
Portfolio Trading
Year-to-date May 2025, estimated market share of U.S. credit portfolio trading is 18.6%, compared to 14.1% in the prior year same period, an increase of approximately 450 basis points. 2
90% of all portfolio trading ADV was executed over X-Pro in May.
Dealer-Initiated
Dealer-initiated ADV increased 41% to $1.8 billion.
May 2025 Variable Transaction Fees Per Million 1 (See table 1D)
The decline in total credit FPM compared to the prior year was driven principally by protocol mix. Total credit FPM was flat month-over-month.
The decline in total rates FPM compared to the prior year was driven by the impact of product mix. Total rates FPM was down slightly month-over-month.
*All comparisons versus May 2024 unless noted.

1 The FPM for total credit and total rates for May 2025 are 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 Due to variances in how portfolio trading market participants utilized the portfolio trading TRACE 'flag,' the Company previously used its own internal methodology for calculating portfolio trading as an estimated percentage of TRACE volume and the Company's estimated market share. Starting in June 2024, the Company utilized the portfolio trading TRACE flag in its reported portfolio trading TRACE volume and the Company's portfolio trading estimated market share.
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 'SD PT' is defined as single-dealer portfolio trades. The Company is currently highlighting the impact of single-dealer portfolio trading volume on U.S. high-grade and U.S. high-yield trading volume and estimated market share, but will continue to exclude single-dealer portfolio trading activity from each product's aggregated trading volume and estimated market share and the total credit FPM calculation.
