tZERO Group, Inc., a key player focused on blockchain-powered multi-asset infrastructure, announced a significant expansion of trading availability on its SEC-regulated Alternative Trading System (ATS). Effective as of Dec 15, 2025, the ATS will reportedly support “24/7 order entry and 23.5 hours of trading on all business days, with execution windows running from 12:05am to 11:35pm ET, Monday through Friday, excluding market holidays.” The ATS is “operated by tZERO’s broker-dealer subsidiary, tZERO Securities, LLC.”
This enhancement marks a step forward in tZERO’s convergence strategy, which envisions a “unified and interoperable smart contract-driven infrastructure providing 24/7 cross-border and cross-asset access to tokenized and traditional assets.”
By expanding trading windows to nearly the full business day, tZERO brings its platform closer to “the round-the-clock availability that defines modern digital markets.”
The update applies to assets eligible to trade on the tZERO ATS’s “regulated, and institution-ready infrastructure.”
This enhancement is part of tZERO’s broader mission “to create a connected, multi-asset platform that bridges traditional finance and Web3 through regulated, programmable, and accessible infrastructure.”
As noted in the update, tZERO Group, Inc. and its broker-dealer subsidiaries provide an innovative liquidity platform “for private companies and assets.”
They offer institutional-grade solutions for “issuers looking to digitize their capital table through blockchain technology, and make such equity available for trading on an alternative trading system.”
tZERO, through its broker-dealer subsidiaries, democratizes access to private assets by providing “a simple, automated, and efficient trading venue to broker-dealers, institutions, and investors.”
All tech services are offered via tZERO Technologies, LLC.
As mentioned in the announcement, tZERO Digital Asset Securities, LLC is a broker-dealer registered with the SEC and a member of FINRA and SIPC. It is the broker-dealer custodian of “all digital asset securities offered on tZERO’s online brokerage platform.”
It operates in accordance with the SEC’s statement, dated December 23, 2020, regarding “the Custody of Digital Asset Securities by Special Purpose Broker-Dealers.”
As clarified in the update, digital asset securities may not be “securities” as defined “under the Securities Investor Protection Act (SIPA)-and in particular, digital asset securities that are “investment contracts” under the Howey test but are not registered with the Securities and Exchange Commission are excluded from SIPA’s definition of “securities”-and thus the protections afforded to securities customers under SIPA may not apply.”
