SEC studies 24-hour stock trading model

TLDR

The SEC is examining whether US stock markets could move to a 24-hour trading model, bringing equities closer to cryptos always-on access.

1. The study looks at how continuous trading might work for stocks and ETFs, as regulators respond to markets already trending toward crypto-like access.
2. Around-the-clock equities would accelerate convergence between traditional markets and crypto, reinforcing trends like tokenized stocks and 24/7 onchain derivatives.
3. The key signals to watch are pilot programs, formal SEC rulemakings, and how major brokers and exchanges upgrade surveillance, risk controls, and infrastructure.

Deep Dive

1. What The SEC Is Looking At

Reporting on US regulation notes that the SEC is exploring a 24-hour stock trading model as markets move toward crypto-like access, framing it as part of a broader modernization of market structure and investor access to securities. This implies an internal study or early-stage policy work rather than a finalized rule.

Today, US equities trade in a narrow window with limited pre-market and after-hours sessions. Crypto trades continuously, and newer venues are already offering perpetual futures and tokenized shares around the clock. The SECs interest is driven by this gap, plus advances in technology, AI-driven trading, and global retail participation that no longer fits a 6.5-hour day.

Regulators will focus on investor protection, liquidity quality at 3 a.m. versus 3 p.m., and whether surveillance and clearing systems can safely handle continuous trading without increasing manipulation or systemic risk.

2. Convergence With Crypto Market Structure

Crypto venues are already showing what 24/7 equities could look like. Jupiter, a Solana-based platform, has announced 24/7 onchain trading of tokenized equities, explicitly marketing access at 2am, on Saturdays, and on Christmas Day. Ondo Finances Ondo Perps offers 24/7 perpetual futures on equities and commodities, with near-centralized speed and onchain settlement.

At the same time, Wall Street is experimenting with AI agents that manage portfolios and trading activity continuously, potentially increasing demand for always-open stock markets as described in a recent CNBC feature on 24/7 AI trading agents.

For crypto users, this is structural convergence. The more traditional assets trade continuously, the easier it becomes to run unified strategies across BTC, ETH, tokenized stocks, and equity derivatives without artificial market closed gaps.

3. Signals And Next Steps

The current work appears exploratory, not yet a concrete rule proposal. The next meaningful milestone would be a public concept release, pilot framework, or formal rulemaking where the SEC asks for comment on continuous trading for stocks and ETFs.

Practical constraints are significant. Exchanges and clearing houses would need upgraded systems, brokerages would have to rethink margin, disclosures and customer protections across time zones, and regulators would need around-the-clock surveillance comparable to what is now being built for prediction markets and crypto platforms.

Confidence: moderate because the study is reported by credible outlets but no detailed SEC proposal has been published yet. For now, the clearest signals to watch are exchange and broker announcements about test environments, plus any SEC papers that explicitly mention 24-hour models.

Conclusion

The SECs interest in a 24-hour stock trading model is another sign that traditional markets are moving toward the always-on structure crypto has had for years. If this progresses from study to pilots and rules, expect tighter integration between tokenized assets, crypto derivatives, and conventional equities, along with a heavier focus on surveillance and risk controls across all of them. For crypto users, that convergence could expand opportunity but will also raise the regulatory bar for any platform claiming to be a serious venue.
