Nasdaq sets a target date for 23-hour trading
Nasdaq said its 23-hour trading framework, branded as “Global Trading Hours,” is targeting a Dec. 6, 2026 launch. If it goes live on schedule, U.S. stocks listed on the exchange would trade five days a week with only a one-hour daily pause, extending the trading day from the current 16 hours to 23 hours.
The U.S. Securities and Exchange Commission approved the proposal on April 10. Nasdaq had filed it on Dec. 29, 2025, putting the review period at roughly three and a half months. The remaining condition is that DTCC clearing systems and the Securities Information Processor, or SIP, complete their overnight upgrades.
Nasdaq Chair and CEO Adena Friedman said the company is “excited to lead the market into an Always-On transition” and said it believes it can set a new standard for regulated markets in the global digital economy.
How the new schedule would work
The proposed structure splits the trading day into two blocks. Day trading hours would run from 4:00 a.m. to 8:00 p.m. Eastern Time, while the overnight session would run from 9:00 p.m. to 4:00 a.m. the next day. The market would close for one hour from 8:00 p.m. to 9:00 p.m.
Nasdaq said that 60-minute break is needed for system maintenance and testing, as well as for processing next-day corporate actions such as dividends and stock splits. On a weekly basis, the market would open at 9:00 p.m. on Sunday and continue through 8:00 p.m. on Friday.
The one-hour shutdown also explains why the model stops at 23 hours instead of moving to round-the-clock trading. The report notes that crypto markets have operated on a 24/7 basis for years because settlement happens on-chain, while traditional equities still rely on batch-based clearing architecture. Under that setup, one hour is the practical technical limit.
Nasdaq plans a 20% overnight guardrail
Nasdaq is not treating the overnight market as a fully unconstrained venue. During the overnight session, a static price band will apply, generally set at 20% above or below the official closing price. Orders outside that range will be rejected outright.
Major corporate actions will also be kept out of the overnight session. Events including stock splits, reverse splits, SPAC exits, and ticker symbol changes will trigger an M1 halt code before the night session starts, with trading resuming at 8:00 a.m. the next morning.
The exchange also made clear that daytime trading will remain the main setting for price discovery. The regular session from 9:30 a.m. to 4:00 p.m. Eastern will continue to carry that role, while the overnight session is positioned more as a venue for investors in Asia and Europe to react to news rather than a replacement for the opening bell.
Nasdaq pointed to current market data to support that distinction. About 2% of cash equity trading volume now takes place outside standard hours, while Nasdaq-100 futures have already been trading on a 24x5 basis.
Main concerns center on liquidity and the loss of a pause
The industry’s concerns cluster around two issues. One is thinner overnight liquidity, which can widen bid-ask spreads and make execution prices less predictable for retail investors using market orders in the middle of the night. The other is the loss of a natural pause in the market. Material news would no longer have to wait until the open to hit prices and could turn into immediate sell or buy orders overnight.
Tokenized securities are part of the next phase
Longer trading hours are only one part of Nasdaq’s broader push. The SEC approved Nasdaq’s proposal for tokenized securities trading on March 18. The scope covers Russell 1000 constituents and ETFs tied to the S&P 500 and Nasdaq-100.
Under that framework, eligible participants would be able to choose blockchain token settlement for trades. The tokenized instruments would share the same ticker symbols, the same price, and the same shareholder rights as the traditional shares. The first tokenized trades could arrive by the end of the third quarter, provided DTC completes its system update.
Nasdaq is also working with Kraken on a tokenized stock gateway connected to xStocks to link on-chain and off-chain liquidity. That project is targeting a launch in the first half of 2027.
The sequence described in the report is straightforward: compress settlement from T+2 to T+1, extend trading to 23 hours, and then enable stock settlement in token form.
Other venues are moving in the same direction
Nasdaq is not alone in pursuing longer trading windows:
- NYSE Arca is also targeting Dec. 6, with trading from 1:30 a.m. to 11:30 p.m. Eastern Monday through Thursday, and until 8:00 p.m. on Friday.
- 24X National Exchange received SEC approval in 2024 for 23-hour trading and plans a phased rollout in the second half of 2026.
- Cboe is pushing 24x5 trading on EDGX, though approval is still pending.
- London Stock Exchange plans to launch night trading in early 2027.
- SEC Chair Paul Atkins is set to hold a 24-hour trading roundtable in Washington on Sept. 17.
Taiwan brokers will also need system changes
The report said regulators in Taiwan have already started preparing for the shift. In January 2026, authorities notified brokers to get ready for changes affecting offshore brokerage orders. There are currently 37 brokers in Taiwan handling that business. Most existing order models still align with regular U.S. stock trading hours or allow limited pre-market booking, so supporting a night session would require system-wide changes.
