"We are moving towards a new day – and night – in the U.S. equity markets." — Paul S. Atkins, Chairman, U.S. Securities and Exchange Commission
The U.S. Securities and Exchange Commission hosts a public roundtable on September 17, 2026, at its Washington headquarters to evaluate operational, surveillance, and settlement requirements for extending U.S. equity trading to near-continuous hours. Panelists from BlackRock, NYSE, Nasdaq, DTCC, Jane Street, Schwab, and 10 other major institutions will address three core questions: whether exchanges and broker-dealers are operationally prepared, whether market infrastructure can sustain round-the-clock resilience, and what the liquidity and capital-formation effects of always-on trading would be.
The roundtable marks the regulatory culmination of a sequence that began with 24X National Exchange launching 23/5 trading in October 2025, continued with the SEC approving Nasdaq's 23-hour weekday trading model on April 10, 2026, and now converges with the DTCC's July 15 tokenization milestone — where 30-plus firms including Goldman Sachs, Vanguard, and JPMorgan executed real production trades using DTC-tokenized assets. The parallel threads of extended hours and on-chain settlement are merging into a single structural shift: the end of the closing bell as a hard stop.
The SEC's roundtable (File No. 4-913) runs from 10:00 a.m. to 4:00 p.m. ET at 100 F Street NE, Washington, D.C., streamed live on sec.gov. Three panels structure the day:
Panel 1 — Operational Readiness covers overnight surveillance, closing-price processes, and clearance/settlement changes. Panelists include representatives from Robinhood, NYSE, BlackRock, Virtu Financial, Cboe, BNY Pershing, UBS, and FINRA.
Panel 2 — Market Resilience addresses systems capacity, Regulation SCI compliance, failover planning, and overnight trading rules. Participants include Nasdaq, DTCC, Jane Street, State Street, Charles Schwab, and Interactive Brokers.
Panel 3 — Market Impact examines liquidity effects, capital formation, market participation, and potential expansion toward full 24/7 trading. This panel will assess whether continuous trading improves price discovery for global investors or fragments liquidity into thin overnight sessions.
The roster represents the core of U.S. equity market infrastructure: the two largest exchanges (NYSE and Nasdaq), the central clearinghouse (DTCC), the largest asset manager (BlackRock), and the dominant retail platforms (Robinhood, Schwab, Interactive Brokers).
The roundtable is not theoretical. The SEC has already approved multiple extended-hours frameworks:
24X National Exchange became the first SEC-licensed exchange to offer 23-hour weekday trading when it launched in October 2025. Currently operating from 4:00 a.m. to 8:00 p.m. ET, the exchange expects to launch full 23/5 trading — 8:00 p.m. Sunday through 8:00 p.m. Friday with a one-hour daily maintenance pause — in the second half of 2026, pending a temporary exemption from the Securities Information Processor plan.
Nasdaq received SEC approval on April 10, 2026, for a 23-hour model: a day session from 4:00 a.m. to 8:00 p.m. ET and a night session from 9:00 p.m. to 4:00 a.m. ET, with a one-hour maintenance window.
NYSE Arca applied in February 2025 for 22-hour weekday trading and is targeting a 2026 launch, contingent on market-data and clearing infrastructure alignment.
The aggregate effect: three exchanges are now at various stages of deploying near-continuous trading, covering the majority of U.S. equity volume. The market processes between 10 and 12 billion shares daily, valued at approximately $80.8 billion on NYSE alone as of July 2026.
Running parallel to the extended-hours push is an institutional tokenization build-out that reached a production milestone on July 15, 2026, when DTCC processed its first tokenized trades through DTC — the entity that custodies over $114 trillion in U.S. securities.
Over 30 firms participated in the production trades, executing seven transaction types: collateral pledge, securities lending, U.S. Treasury and repo delivery-versus-payment, equity DVP, equity delivery-versus-delivery, equity token transfer, and central counterparty margin workflows. The participant list included Goldman Sachs, JPMorgan, Vanguard, BlackRock, Citadel Securities, CME Group, Nasdaq, NYSE, Circle, Chainlink, State Street, and Virtu Financial, among others. The DTCC Tokenization Service is scheduled for full launch in October 2026.
Frank La Salla, DTCC President and CEO, stated the initiative "demonstrated that we can apply the same institutional rigor to tokenization as we do for traditional assets." The trades processed on two networks: Linux Foundation Decentralized Trust's Besu (private) and Canton (public), following a multi-chain approach.
Separately, the SEC approved Nasdaq's tokenized equity pilot on March 19, 2026. Under the framework, tokenized shares of Russell 1000 stocks and ETFs linked to the S&P 500 and Nasdaq-100 will trade on the same order book as traditional shares under the same ticker, with identical pricing and investor rights. Post-trade settlement flows through DTC. Nasdaq has partnered with Kraken for securities tokenization conversion.
NYSE announced in January 2026 that it is developing a tokenized securities platform offering 24/7 operations, instant settlement, dollar-denominated order sizing, and stablecoin-based funding. The SEC approved NYSE's proposed rule change enabling trading of tokenized securities on April 17, 2026. The platform combines NYSE's Pillar matching engine with blockchain-based post-trade systems.
On September 1, 2026, the SEC proposed the first substantive rewrite of transfer agent rules since their adoption in the late 1970s. The proposed regulation adopts technology-neutral language that expressly permits transfer agents to use distributed ledger technology — including blockchain — as part of, or as the entirety of, the master securityholder file.
The proposal amends Forms TA-1 and TA-2, rescinds Rule 17ad-4, and introduces two new rules: Rule 17ad-30 (compliance programs) and Rule 17ad-31 (restrictive legends and unregistered transactions). Comments are due November 3, 2026.
This is not a standalone initiative. Combined with the tokenization pilots and extended-hours approvals, it signals that the SEC under Chairman Atkins is building a regulatory stack — from recordkeeping at the transfer-agent level through to execution on exchange matching engines — that accommodates blockchain-native securities infrastructure.
The roundtable's agenda implicitly acknowledges unresolved structural problems:
Settlement mismatch. U.S. equities settle on a T+1 cycle. Blockchain-based tokenized securities enable near-instant or atomic settlement. Running both settlement paradigms simultaneously introduces reconciliation complexity. The DTCC pilot tested this dual-track approach, but scaling it to full production across asset classes remains untested at market-wide volume.
Surveillance gaps. Overnight trading sessions operate with thinner liquidity, increasing vulnerability to manipulation. FINRA's presence on Panel 1 signals regulatory concern about surveillance capacity during non-standard hours. The 24X exchange's current SIP exemption request suggests the consolidated tape infrastructure is not yet ready for continuous data feeds.
Custody and shareholder rights. The SEC's forthcoming "innovation exemption" for tokenized securities — described by staff as limited in scope rather than blanket deregulation — must address custody rules for on-chain tokens, the legal relationship between a token and the underlying security, and whether third parties can tokenize without issuer permission.
Operational resilience. Panel 2's focus on Regulation SCI compliance, failover procedures, and staffing models highlights that 24-hour markets require 24-hour human and system oversight — a cost that accrues disproportionately to smaller broker-dealers.
The convergence of extended-hours trading and tokenization creates measurable economic effects:
Capital efficiency. Instant settlement eliminates the capital locked in the T+1 gap. For a market processing approximately $80.8 billion daily on NYSE alone, even marginal reductions in settlement risk translate to significant capital release for broker-dealers and clearing firms.
Global access. Continuous trading allows Asian and European investors to access U.S. equities during local business hours without routing through after-hours dark pools. Kraken's xStocks product — currently offering 24/7 trading in 10 tokenized assets including TSLAx, NVDAx, and SPYx — demonstrates retail demand for this access, though these instruments are structured as debt securities rather than equity ownership.
Fee compression. The entry of crypto-native platforms (Kraken, Coinbase) into tokenized equities via exchange partnerships introduces new competitive pressure on execution and settlement fees. However, the DTCC's central role in the tokenization pilot suggests incumbent infrastructure will absorb, rather than be displaced by, blockchain-based settlement.
Fragmentation risk. Three exchanges deploying different extended-hours schedules, each with different maintenance windows, could fragment overnight liquidity rather than consolidate it. The roundtable's Panel 3 is tasked with assessing this risk.
The September 17 roundtable is not the beginning of 24-hour trading — 24X has been live since October 2025, and Nasdaq's 23-hour framework is approved. It is, instead, the point at which the SEC formally evaluates whether the rest of the market's plumbing — surveillance, settlement, clearing, and resilience — can support what the exchange approvals have already set in motion.
The tokenization track adds a second dimension. When the DTCC launches its Tokenization Service in October 2026, the infrastructure will exist for securities to be both continuously tradeable and instantly settleable. The transfer agent rule proposal closes the third gap: legal recognition of blockchain as a recordkeeping system.
These are not independent initiatives. They constitute a coordinated, if incremental, rewiring of U.S. equity market structure. The economic question is not whether 24-hour tokenized trading will exist — that is now a matter of operational deployment timelines — but whether the capital-efficiency gains from instant settlement and continuous access outweigh the fragmentation, surveillance, and operational costs of always-on markets. The roundtable's three panels are structured to answer precisely that question.
