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 February 2026.¹

Chris Concannon, CEO of MarketAxess, commented:
“We generated strong variable commission revenue growth to start 2026, driven by 20% growth in total credit ADV year-to-date, and benefiting from a 3% increase in total credit FPM month-over-month in February. Our estimated U.S. high-grade market share in February was negatively impacted by strong new issuance and a decrease in portfolio trading activity by our core clients. As we have noted previously, portfolio trading activity can fluctuate significantly month-to-month as clients modulate activity. We believe that the recent geopolitical events, as well as the very strong new issuance calendar year-to-date are supportive of a return to higher levels of volatility, as well as an increase in the velocity of trading in the global credit markets."

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

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

Client-Initiated Channel

• 30% growth in block trading average daily volume (“ADV”), with strong growth across U.S. credit (+30%), including U.S. high-grade ADV of $2.6 billion (+38%), as well as emerging markets ADV of $2.0 billion (+22%) and eurobonds ADV of $596 million (+57%).

Portfolio Trading Channel

• 5% increase in total portfolio trading ADV to $1.5 billion.
• Our estimated market share of U.S. credit portfolio trading was 15.6%, compared to 20.7% in the prior year.

Dealer-Initiated Channel

• Dealer-initiated ADV of $1.8 billion was down slightly compared to the prior year. Total Mid-X trading volume was $5.2 billion, representing an increase of 93%.

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

• The decline in total credit FPM year-over-year was driven principally by product and protocol mix, partially offset by the higher duration of bonds traded in U.S. high-grade. The increase month-over-month was driven by product and protocol mix, slightly offset by the lower duration of bonds traded in U.S. high-grade.
• The increase in total rates FPM year-over-year was driven by the impact of client and protocol mix. The decrease in total rates FPM month-over-month was driven by the impact of client and protocol mix.

*All comparisons versus February 2025 unless noted.
