tZERO Group, Inc. announced a major expansion of trading availability on its SEC-regulated Alternative Trading System, with 24/7 order entry and 23.5 hours of trading on business days beginning December 15, 2025. The execution windows will run from 12:05am to 11:35pm ET, Monday through Friday, excluding market holidays, through the ATS operated by tZERO's broker-dealer subsidiary, tZERO Securities, LLC. This enhancement represents a substantial step in tZERO's global convergence strategy, which aims to create unified smart contract-driven infrastructure for seamless cross-border and cross-asset access to both tokenized and traditional assets.
By extending trading windows to nearly the full business day, the platform moves closer to the round-the-clock availability that characterizes modern digital markets. The update applies to all assets eligible to trade on the tZERO ATS's regulated infrastructure, which is designed to meet institutional requirements. This development is part of tZERO's broader mission to create a connected, multi-asset platform that bridges traditional finance and Web3 through regulated, programmable, and globally accessible infrastructure.
Alan Konevsky, Chief Executive Officer, emphasized the strategic importance of this move, stating that the company needs to offer a trading environment that truly reflects where capital markets are heading. He noted that this enhancement drives the demand and liquidity leg of tZERO's strategic priorities by making the open infrastructure more appealing to the digitally native community that operates worldwide around the clock and more interoperable with other tokenized assets.
