[DigitalToday reporter Jinju Hong] The U.S. Securities and Exchange Commission will hold a public roundtable in September on shifting the U.S. stock market to 24-hour trading.
Cointelegraph, a blockchain outlet, reported on Thursday that the SEC plans to discuss expanding overnight trading and ways to run a 24-hour market at its Washington headquarters on Sept. 17.
The meeting will examine whether the U.S. stock market can move from a structure centered on a traditional close to a de facto around-the-clock trading system. The SEC plans to address preparations to support overnight trading, operations in a 24-hour market and system resilience issues.
SEC Chairman Paul Atkins said the U.S. stock market is moving into a new phase. In a statement on Thursday, he said the U.S. stock market is “heading into a new day, and night,” and expressed 기대 in the possibility of keeping pace with markets where continuous trading is already taking place by expanding overnight trading. He said he looks forward to the outlook for the U.S. stock market to align with continuously traded markets.
The discussion coincides with a broader push by major exchanges to extend trading hours. Global exchanges are reviewing or introducing models closer to the around-the-clock trading format first established by cryptocurrency exchanges. For retail investors, this broadens the basis for buying and selling stocks for longer hours outside regular sessions.
In the United States, Nasdaq has already begun work on institutional changes. Nasdaq said it began discussions in March with U.S. regulators on offering 24-hour trading five days a week. The target timeframe is the second half of 2026. Nasdaq said regulatory approval and alignment are needed as conditions for implementation, meaning institutional approval and market infrastructure adjustments must proceed in parallel for an actual launch.
Moves to expand are also continuing by exchange. Cboe is pushing to launch 24-hour stock trading. The London Stock Exchange is reported to be preparing an option to roll out an overnight trading platform in early 2027. As major exchanges in the United States and Europe move in a similar direction, stock markets are undergoing a structural change in which time constraints are reduced, like in crypto markets.
The SEC meeting is expected to gauge whether these changes go beyond a simple expansion of services and lead to a restructuring of market structure. As overnight trading increases, operational issues such as order-processing stability, responses to system disruptions and market surveillance systems are likely to come into focus. The SEC put preparations and resilience on the agenda as separate topics for that reason.
Key points to watch will be the pace of regulatory approval, coordination among exchanges and whether actual market participation expands. Nasdaq’s timetable for the second half of 2026 also depends on regulatory approval. As a result, the September meeting could be a turning point in whether longer trading hours for U.S. stocks remain at an experimental stage or move toward institutionalisation.
