IMTC Integrates MarketAxess Liquidity Into Fixed Income Workflows

Fixed income technology provider IMTC announced on September 9, 2026 an integration with MarketAxess Holdings Inc. (MKTX ) that makes MarketAxess liquidity accessible from IMTC’s portfolio and order management workflows, allowing mutual clients to route orders to the electronic fixed income platform directly from the IMTC system.

Under the integration, mutual clients can route orders to MarketAxess from the platform where their portfolio decisions are made and access its liquidity across credit products while maintaining compliance and operational controls, according to IMTC’s announcement. In a Q&A published with the release, IMTC stated that the routed orders are the output of its optimization workflows, already checked against the firm’s compliance rules, so they are not rebuilt in a separate execution system. A portfolio manager can send trades to the MarketAxess marketplace from the same environment used to build, optimize, and monitor portfolios.

The companies stated the relationship is designed to bring MarketAxess’ electronic marketplace and liquidity closer to the point of portfolio decision-making, directly within IMTC’s portfolio construction and optimization workflows. It is also intended to support portfolio managers in scaling custom fixed income portfolios, model-driven strategies and separately managed accounts by linking IMTC’s optimization outputs with MarketAxess’ electronic trading protocols and liquidity pools. A third stated goal is to help mutual clients improve execution quality, reduce transaction costs, and streamline end-to-end trade workflows from idea generation and portfolio construction through execution and reporting.

IMTC’s Q&A describes the scaling mechanism as turning many portfolio decisions into executable orders without adding manual work for every account. Because the integration links IMTC’s optimization outputs directly to MarketAxess’ trading protocols, a manager can optimize across accounts, run compliance checks, and route the resulting orders in one connected flow, the company stated.

Spencer Lee, MarketAxess’ head of products for the Americas, said: “By integrating with IMTC’s portfolio and order management technology, we are embedding that liquidity directly into the investment workflow, making it easier for our mutual clients to discover opportunities, execute with confidence, and achieve better outcomes across fixed-income markets.”

IMTC chief executive Russell Feldman said: “As firms look to scale fixed income management, PMs need optimization, compliance, and execution to operate in one connected workflow.” He added that the partnership allows mutual clients to tap into a deep liquidity network while turning portfolio decisions into executable orders with greater precision, scale, and auditability.

The release describes MarketAxess as an electronic trading platform operator whose patented technology is used by approximately 2,100 firms. Founded in 2000, the company offers its Open Trading all-to-all marketplace, automated and algorithmic trading solutions, data and index products, and post-trade services across the global fixed-income markets. IMTC describes itself as providing end-to-end portfolio and order management, compliance, and reporting on an AI-enhanced fixed income platform. MarketAxess also carried the announcement on its investor-relations news page dated September 9, 2026.

Earlier Venue Agreements

The MarketAxess integration follows a series of IMTC announcements in 2025 and 2026. On July 7, 2026, IMTC announced an agreement with ICE Bonds, part of Intercontinental Exchange (ICE ), Inc., integrating click-to-trade access to ICE Bonds’ BondPoint and TMC marketplaces into IMTC’s portfolio and order management workflows. ICE Bonds President Peter Borstelmann said at the time that the integration made fixed income liquidity more accessible for mutual clients and helped them achieve greater execution certainty when trading through the two marketplaces. Feldman said the agreement embedded electronic trading capabilities directly into IMTC so clients could optimize and execute within one connected workflow. IMTC described that agreement as consistent with its strategy of connecting portfolio construction, optimization, compliance, and trading in a single fixed income workflow, an approach its Q&A says the MarketAxess relationship extends.

IMTC’s press archive also records a July 23, 2026 platform selection by Moneta, which IMTC describes as a $50 billion RIA in St. Louis, and a March 17, 2026 agreement under which Nomura Asset Management International selected IMTC’s platform to scale customized separately managed account capabilities across taxable and tax-exempt strategies. On December 4, 2025, IMTC announced the closing of a $12 million Series A round led by Nyca Partners with a strategic investment from Lord Abbett.

Pending ICE Acquisition of MarketAxess

MarketAxess is also the subject of a pending acquisition. On July 30, 2026, Intercontinental Exchange announced a definitive agreement to acquire MarketAxess for $167 per share in cash, a 33% premium to MarketAxess’ closing price on July 29, 2026, representing an equity value of approximately $6.0 billion and a total enterprise value of approximately $5.7 billion. ICE stated the transaction was unanimously approved by both companies’ boards and is expected to close in the first half of 2027, subject to MarketAxess stockholder approval, applicable regulatory clearances, and customary closing conditions.

That release states MarketAxess connects approximately 2,100 institutional investors and broker-dealers across more than 90 countries, enabling electronic trading in corporate bonds, municipal bonds, emerging market debt, Eurobonds, U.S. Treasuries, and other fixed income instruments. ICE said it plans to finance the all-cash consideration through newly issued debt, a mix of bonds, a term loan and commercial paper, and that it expects $100 million in annual run-rate expense synergies to be fully realized within three years after closing, with the transaction expected to be accretive to adjusted earnings per share in the first full year. The release names BofA Securities as financial advisor to ICE and J.P. Morgan Securities LLC as financial advisor to MarketAxess.
