OneChronos launches European trading venues to bring new market design and optimisation to pan-european equities. * 6 hrs ago OneChronos today announced the production launch of its European trading venues, OneChronos Markets UK Limited and OneChronos Markets NL B.V., providing institutional investors with access to pan-European equities and equity-like instruments through a fundamentally different approach to market design and best execution. The launch represents the next milestone in OneChronos' international growth strategy, extending its distinctive market model into Europe through fully authorised UK and EU Multilateral Trading Facilities (MTFs). The venues provide institutional investors, brokers and liquidity providers with an additional destination for trading pan-European equities and equity-like securities, supporting increasingly sophisticated best execution objectives. Alebund Pharmaceuticals on Business Outlook Full production trading begins today with a strong pipeline of Day One subscribers already connected and prepared to participate, representing leading global investment banks, agency brokers and institutional trading firms. Additional participants are expected to onboard throughout the coming months as liquidity continues to develop across the two venues. "With the launch of our UK and EU regulated MTFs, OneChronos takes another step forward as a multi-asset, multi-geography trading venue operator," said Adam Sherlock, CEO of OneChronos Markets NL B.V. "We're excited to bring market participants in the region greater choice in where and how they trade, and we look forward to working closely with the industry as liquidity continues to grow." Building on the success of the OneChronos ATS platform in the United States, the European business combines the widely adopted Periodic Auction trading mechanism with a next-generation matching model founded on mathematical optimisation, auction theory and expressive trading. Rather than prioritising speed alone, the OneChronos market is designed around a simple principle: quality over speed. "Today marks an important milestone for OneChronos as we extend our market model into Europe," said Scott Bradley, CEO of OneChronos Markets UK Limited. "We believe market structure should focus on delivering the highest quality execution outcomes rather than simply rewarding the fastest participant. By combining the familiarity of periodic auctions with mathematical optimisation and expressive trading techniques, we are introducing a genuinely differentiated execution venue that is designed around investor outcomes, fairness and efficient liquidity formation." The OneChronos MTFs solve for the optimal outcome across all eligible orders submitted to each auction, seeking to maximise overall execution quality while allowing market participants to express richer trading preferences than traditional market models permit. The result is an innovative marketplace designed to improve liquidity formation while helping participants achieve better execution outcomes. Unlike conventional auction matching engines that evaluate orders sequentially on a price-time basis, the OneChronos MTFs evaluate the set of eligible orders simultaneously using advanced mathematical optimisation techniques. This enables the market to identify trading opportunities that would potentially otherwise remain undiscovered, and is designed to create additional opportunities for price improvement, larger executable size and enhanced liquidity interaction. The European launch reflects continued demand from market participants for innovative execution models capable of addressing increasingly complex trading objectives while complementing existing exchange and MTF ecosystems. As adoption grows, OneChronos expects its European venues to become an increasingly important component of institutional execution strategies. About OneChronos OneChronos is building the bazaar for agentic systems, starting in capital markets, where its matching markets routinely account for more than 1% of notional U.S. equity market volume. By bringing together auction theory, distributed systems, artificial intelligence, and deep market structure expertise, OneChronos helps humans and agentic systems transact more efficiently, improve how value is allocated, and, ultimately, increase global GDP. The OneChronos group of companies operate regulated trading venues in both the United States and Europe. It recently launched FX Spot trading in March this year, and focuses on delivering innovative market structure solutions that place execution quality ahead of execution speed. Global multi-asset plans continue in 2027 with a planned rollout of the model in Japan and a move into Rates in the U.S., including US Treasuries. Media gallery

OneChronos has launched a spot foreign exchange trading venue, marking its first expansion beyond US equities. The platform introduces an optimisation-based auction model to global currencies, building on technology used in its equities ATS that averaged $12.66 billion in daily trading volume in January. The venue addresses inefficiencies in the $7.5 trillion daily FX market by coordinating trades across multiple currency pairs through multilateral auctions, rather than sequential bilateral transactions. This approach aims to reduce information leakage and improve price execution. OneChronos FX integrates into existing trading infrastructure, allowing firms to extend the same execution logic across asset classes. Since launching its US equities ATS in 2022, OneChronos has facilitated approximately $2.85 trillion in total institutional securities transactions as of January 2026.

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.
