SEC pushes 24-hour blockchain stock trading

TLDR

The SEC is exploring how U.S. stocks could move to near?24/7 trading supported by blockchain?based infrastructure, but nothing has been approved yet.

1. The SEC has scheduled a September 17 roundtable with NYSE, Nasdaq, BlackRock, Citadel and others to examine continuous stock trading and required safeguards.
2. In parallel, the SEC is drafting an innovation exemption and updated transfer?agent rules so tokenized stocks on blockchains can trade 24/7 within the securities rulebook.
3. For crypto users, this accelerates convergence between tokenized equities and digital assets, but timing, liquidity quality and final rule details remain the main uncertainties.

Deep Dive

1. What The SEC Is Actually Doing

The SEC will host a public roundtable on 17 September 2026 in Washington to discuss operational readiness, surveillance and settlement for potential 24?hour U.S. equity trading, with participants including BlackRock, Citadel Securities, NYSE, Nasdaq, Robinhood and DTCC, streamed live on its site. This is framed as a fact?finding and design session rather than a green light for 24/7 markets, and any rule change would need a separate proposal and comment process.The roundtable agenda focuses on overnight trading risks, infrastructure and investor protections.

Separately, the SEC has started work on an innovation exemption that would permit 24/7 trading of tokenized stocks via blockchain, and proposed a major overhaul of transfer?agent rules so blockchain?based ledgers can serve as official ownership records for tokenized securities.A recent policy summary and a later update on transfer?agent reforms make this explicit.

2. Why This Matters For Crypto And Tokenized Assets

Crypto markets already trade 24/7. The SECs push would bring U.S. stocks closer to that model, especially where they are tokenized on blockchains and trade alongside crypto.

Issuer?sponsored tokenized securities, where on?chain movements directly update the official share register, are gaining traction among exchanges and transfer agents, and the SECs proposals aim to give these arrangements a clear legal framework.A recent overview of tokenization and transfer?agent reforms highlights this shift.

If implemented, brokers, centralized exchanges and on?chain venues could offer 24/7 access to tokenized ETFs, stocks and funds, blurring the line between crypto trading and equity trading and potentially deepening liquidity for on?chain assets.

3. Key Risks And What To Watch Next

Short term, the 17 September SEC roundtable is the key event to watch, especially whether the Commission signals a timeline for actual rule proposals on 24?hour trading and tokenized securities.

Market structure risks are non?trivial. Overnight sessions tend to have thinner books and wider spreads, an issue already recognized in crypto, and regulators at the roundtable are expected to focus on surveillance, staffing, cybersecurity and clearing for off?hours trading.Analysis of the roundtable underscores these concerns.

Also important will be how quickly major venues like NYSEs planned Digital Trading Platform and London Stock Exchanges LSE 24 tokenized stock venue secure approvals, since their designs assume 24/7 blockchain?based settlement that depends on regulatory comfort.Recent reports on NYSEs tokenized platform and LSEs xStocks initiative show that the private sector is already building for this future.

Conclusion

The SEC is not flipping a switch to 24/7 blockchain stock trading today. It is laying the regulatory groundwork, via roundtables and rule proposals, so tokenized equities and traditional stocks can eventually share always on infrastructure similar to crypto. For crypto users, this is a structural convergence story, where tokenization and continuous trading could gradually turn digital asset venues into gateways for a much broader universe of regulated financial assets.
