“In 2025, we made significant strides in enhancing the MarketAxess advantage by expanding our global network, deepening our differentiated liquidity. We also accelerated our use of AI in enhancing the proprietary data and analytics that underpin our protocols and workflow tools for clients, helping them to be more efficient and gain deeper insights into their trading activity.

We delivered record volumes in U.S. credit and record revenue outside of U.S. credit of $406 million, a 10% increase, reflecting the strong returns generated from our investments in these areas. We also made strong progress across our three U.S. credit strategic channels: block trading ADV increased 24%, total portfolio trading ADV increased 48%, and dealer‑initiated ADV increased 33%. Additionally, the Mid‑X solution launched in the second half of 2025 continues to gain momentum, delivering over $3 billion in trading volume in December 2025.

The client initiatives that we expect to deliver in 2026 and beyond include enhancements to our X-Pro platform and our automation suite, as well as the launch of new solutions that allow dealers to send axes directly to investor clients. These enhancements are progressing well and we expect them to drive market share and revenue growth consistent with our medium-term financial targets."
