MarketAxess Holdings Inc. reported trading volume statistics for June and the second quarter of 2026, highlighting record portfolio trading activity and gains in U.S. high-yield market share despite a slight decline in total trading average daily volume (ADV). Total credit ADV for the second quarter was $16.9 billion, flat compared to the prior year, while total trading ADV decreased 11% year-over-year to $43.6 billion.

June 2026 Highlights

Total credit trading volumes showed continued strength in June relative to May levels. U.S. high-grade estimated market share increased approximately 10 basis points to 17.9%, driven by improvement in the client-initiated channel. U.S. high-yield estimated market share increased to 14.9%, up 190 basis points from the prior year and up 100 basis points sequentially.

The company estimates that duplicate trade reports inflated U.S. high-grade TRACE volumes by up to 8% in June 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 150 basis points higher, or approximately 19.4%, in June 2026.

The year-over-year decline in total credit FPM for the second quarter was driven by protocol and product mix, as well as lower duration of bonds traded in U.S. high-grade. The quarter-over-quarter decline in total credit FPM was largely driven by lower duration. The year-over-year and quarter-over-quarter increases in total rates FPM were driven by the impact of protocol mix.
