The Smart Market for Institutional Investors

OneChronos is a U.S. equities ATS designed bottom-up to fundamentally address the growing gap between how trading venues match orders and how traders need to execute.

A fair, intelligent, and customizable ATS.

OneChronos is a Smart Market - the technical term for markets that match counterparties using mathematical optimization. Smart Markets have a proven ability to outperform traditional markets on metrics such as price improvement, liquidity, trade size, and fairness.

Smart Markets enable Expressive Bidding - a tool that gives market participants the fidelity of voice trading and the advantages of an electronic venue. All market participants can benefit from the unique liquidity that Expressive Bidding generates.

Proven results

Smart Markets have been increasingly adopted in sectors such as manufacturing, logistics, telecom, and advertising given their demonstrated ability to:

  • Identify mutually beneficial outcomes for buyers and sellers
  • Address agency issues and reduce incentives for gaming
  • Directly handle substitutes and complements, unlocking transactions that wouldn't be possible otherwise
  • Mitigate information leakage and asymmetry

OneChronos is pioneering the use of Nobel prize-winning (Economic Sciences, 2020) combinatorial auction techniques and artificial intelligence in financial markets, operating a Smart Market at a speed, scale and computational complexity that was not possible until now.
