OneChronos Launches the First Smart Market for Global FX to Improve Execution Quality

Building on its success in U.S. equities, OneChronos introduces a proven optimization-based auction model to one of the world’s largest asset classes

NEW YORK--(BUSINESS WIRE)--OneChronos, the technology company leveraging advances in auction theory and computer science to optimize financial markets, today announced the launch of its new spot foreign exchange (FX) trading venue. OneChronos FX introduces an optimization based auction model to global currencies for the first time, following its scaled deployment in equities through the ATS operated by its sister company, OneChronos Markets LLC.

This marks OneChronos’s first expansion beyond U.S. equities, and brings its Smart Market design to one of the world’s largest asset classes. Smart Markets optimize for institutional measures of trade quality through sophisticated matching technology, and underpin OneChronos’s U.S. ATS equities trading venue that facilitated an average of $12.66 billion in daily trading volume in January. OneChronos FX integrates into established trading workflows, enabling coordinated, multilateral clearing within familiar currency execution practices.

“OneChronos envisions a future where periodic multi-asset auctions let investors seamlessly reallocate across asset classes and geographies,” said Kelly Littlepage, CEO and co-founder of OneChronos. “FX is the connective tissue of global capital markets—making it both a natural proving ground for the combinatorial auctions we’ve validated in U.S. equities and a foundational step toward that broader vision.”

The global FX market trades more than $7.5 trillion per day, but most execution still occurs through decentralized, bilateral workflows. For trades that span multiple currency pairs or venues, participants often piece together fills sequentially, which can increase signaling risk, adverse selection, and legging costs, and make it harder to coordinate execution across related positions.

To address this, OneChronos FX incorporates all currency pair interest within each auction cycle and clears eligible orders through a coordinated optimization process, rather than piecing together execution through sequential bilateral trades. This structure is designed to increase price improvement and reduce information leakage.

The FX venue leverages OneChronos’s proprietary combinatorial auction technology. During each auction cycle, the system evaluates all eligible orders together and determines a single clearing outcome under a defined objective function. This multilateral approach can surface trading opportunities that continuous or bilateral structures often miss.

OneChronos FX is designed to integrate seamlessly into existing trading infrastructure. Participants can access the venue through established workflows, allowing firms active in both equities and FX to extend the same execution logic across asset classes without introducing operational complexity.

“Our goal is to bring the benefits of auctions to Spot FX in a way that fits how firms already trade,” said Blaise Sheppard, Head of FX at OneChronos. “We’ve proven in equities that multilateral auctions can improve pricing and reduce information leakage. Our new FX platform builds on those principles and extends the same approach to currency markets to improve execution quality.”

Since launching its US equities ATS in 2022 and as of the end of January 2026, OneChronos has facilitated a total of ~$2.85 trillion dollars of institutional securities transactions. Asset managers, broker-dealers, banks, and other market participants have adopted the company’s technology to achieve improved execution outcomes within existing market frameworks.
