Trumid, the electronic bond trading platform, reported record average daily volumes of $10.4bn in May, a 53 per cent increase from the same month last year and more than double the rate of growth in the broader US corporate bond market.

The New York-based company said its overall market share rose 27 per cent year-on-year, with particularly strong gains in US investment grade bonds, where market share increased 39 per cent.

The platform’s growth was driven by list-based trading protocols. Combined average daily volumes across portfolio trading and request-for-quote services rose 93 per cent year-on-year, while older trading methods grew 43 per cent over the same period.

Portfolio trading volumes increased 82 per cent, outpacing the estimated 39 per cent growth in portfolio trading across the broader market as measured by TRACE, the bond trade reporting system. Request-for-quote volumes more than doubled, rising 103 per cent.

Trumid also launched a new automated trading capability during the month, called Full Self Trading, which executes orders across multiple protocols based on trader-defined parameters. The company said dozens of institutional clients have adopted the service since late 2025, with median order sizes approaching $5m and some individual orders exceeding $50m.

The platform’s artificial intelligence tools, which convert voice and text conversations into pre-populated trade tickets, have processed approximately $90bn in traded volume so far this year.

More than 12,300 unique bonds traded on Trumid in May, a record for the platform, with over 1,500 traders active during the month.
