NYSE Arca extended hours approved – The SEC granted accelerated approval to lengthen NYSE Arca’s pre and post market so the exchange can operate 22 hours a day, Monday to Thursday (1:30am – 11:30pm ET) and 1:30am – 8:00pm ET on Fridays, subject to industry dependencies. NYSE targets launch in late 2026 pending SIP and DTCC readiness.[1]
Securities Information Processors (SIPs) propose near 24×5 – Within the Consolidated Tape Association Plan/Consolidated Quotation Plan (CTA/CQ Plans) and UTP Plan, the SIPs flagged they would seek 8:00pm ET Sunday to 8:00pm ET Friday operations with a brief nightly pause, contingent on DTCC clearing availability and TRF coverage. The SEC has up to 300 days to act on the amendment.[2]
FINRA Trade Facility Reporting (TFR) expansion filing – FINRA filed to open TRFs at 4:00am ET (currently 8:00am) with implementation in Q1 2026, an incremental step toward aligning off exchange reporting to extended market data hours. [3]
Nasdaq & Cboe timelines – Nasdaq publicly signaled a 24×5 capability as early as H2 2026, subject to approvals and infrastructure alignment. Cboe announced plans to enable 24×5 equities on EDGX, likewise contingent on SIP and SEC approvals.[4]
DTCC (NSCC) extended trade capture – DTCC’s Universal Trade Capture (UTC) will support 24×5 trade processing with client testing from Jan 2026 and production targeted for June 2026. A new FIX Tag 715 (Clearing Business Date) becomes mandatory on UTC real-time output.[6]
Off-hours volumes are already material – NYSE research shows off-hours trading accounted for ~11.5% of US equities activity in Q2 2025, with several single day premarket volume records.[7]
SIFMA/DTCC working groups are pivoting from advocacy to playbook drafting – Agendas now focus on settlement cycle exceptions, corporate actions cutoffs and cyber resiliency for 24 × 5.
Outside the US, similar initiatives are also emerging. LSEG is publicly exploring 24-hour trading. HKEX leaders have discussed a gradual extension to establish systems capable of near 24-hour derivatives trading later in the decade. This article focuses on US implementation, but global alignment will be important for liquidity and client coverage.[8],[9]
