The Sept. 17 event will examine market operations and resilience, while a separate proposal would modernize transfer-agent rules for onchain securities records.
The roundtable portion is directly confirmed by the SEC’s July 23 announcement, which specifies September 17, 2026 and names operations and resiliency in a 24-hour market among its discussion areas. The separate proposal is directly confirmed by the SEC’s September 1 transfer-agent release and proposed rule, which cover blockchain-related activities and blockchain-based recordkeeping. The wording “onchain securities records” is a reasonable shorthand, though the SEC uses more precise terms such as blockchain-based, distributed-ledger, and tokenized securities; the action remains a proposal rather than an adopted rule.
The Securities and Exchange Commission has set the agenda and participants for its Sept. 17, 2026, roundtable on preparations for 24-hour U.S. stock trading and proposed a separate rule updating transfer-agent requirements for blockchain-based securities activity. The public roundtable, arranged amid rising demand from domestic and foreign investors for continuous, crypto-like market access, will run from 10 a.m. to 4 p.m. ET at the SEC’s Washington headquarters and will be webcast live. Participants include representatives from NYSE, Nasdaq, BlackRock, Citi, Charles Schwab, Jane Street, State Street, Citadel Securities, Cboe, DTCC, Robinhood and other financial-market firms. Discussions will cover exchange and broker-dealer readiness, overnight surveillance, closing-price practices, clearance and settlement, systems resilience, cybersecurity, staffing and investor protection, including how the U.S. T+1 cycle would apply to overnight, weekend and holiday trades. SEC Chairman Paul Atkins has pointed to full-time trading’s role in attracting global liquidity while stressing the need for strong safeguards. Major venues including NYSE, Nasdaq and the London Stock Exchange Group, with support from banks such as Citigroup and BNY Mellon, are preparing continuous-market infrastructure, while Robinhood and Charles Schwab are expanding from 24/5 toward 24/7 trading and firms race to support instant settlement and tokenized collateral. The proposed transfer-agent rule, open for a 60-day comment period, would recognize electronic communications and blockchain technology in securities offerings and share transfers, allow blockchains to serve as official transaction records, and add operational controls including cybersecurity requirements. It also raises whether firms should be able to collect email addresses or digital-wallet addresses instead of names and physical addresses for securityholders.
