Starting in December, U.S. stocks will also be traded almost around the clock. Are institutions ready? Is this a bullish development for crypto? U.S. stocks were traditionally a daytime-only market. Regular trading hours corresponded to nighttime in Korea, and by the time morning arrived in Korea, trading had already ended. Thus, even if Bitcoin moved sharply in the early hours, IBIT or Strategy shares would only catch up once regular trading opened. That structure changes on December 6. Nasdaq and NYSE Arca will begin offering 23-hour trading, five days a week. The trading week starts Sunday evening at 9 p.m. Eastern Time and ends Friday evening at 8 p.m. Each day, there is a one-hour maintenance window between 8 p.m. and 9 p.m. Regular trading hours (9:30 a.m. to 4 p.m.) remain unchanged. The new addition is the overnight session from 9 p.m. to 4 a.m. It does not extend to Saturdays like crypto. But the long-held notion that “stocks are only traded during market hours” is now broken. This extension is not an event limited to special securities—it applies to NMS stocks and ETFs, including spot crypto ETFs like IBIT, FBTC, and ETHA. Strategy (MSTR) is a Nasdaq common stock; Bitmine (BMNR) is a NYSE common stock. When crypto moves overnight, there is now a direct channel for ETFs and related equity prices to reflect those moves the same night. However, the exchange opening its doors is separate from whether your brokerage app will allow you to trade those securities overnight. The final decision rests with your broker. ✅ Are institutions ready for overnight trading? Infrastructure is nearly in place. The clearinghouse NSCC is already operating a 24/5 clearing system, and the consolidated tape (SIP) will switch to 23/5 on December 6. Exchange rules have been approved. The exchanges themselves are ready. The issue lies with those who will actually use the doors. Even today, after-hours trading in U.S. stocks accounts for less than 1% of total volume—and even that is concentrated in large-cap stocks and popular ETFs. At the SEC’s recent roundtable on 24/7 trading, the prevailing sentiment was closer to “we have to do it,” rather than enthusiastic adoption. Although major players like BlackRock, Virtu, Jane Street, UBS, Schwab, and Robinhood were present, none have committed to quoting bids and offers overnight starting December 6 like they do during regular hours. Institutions face straightforward barriers to jumping in immediately: staffing for night desks, monitoring systems, availability of collateral, margin lending, short-selling capabilities, and prime brokerage services are not equivalent to daytime operations. Asset managers still haven’t agreed whether it’s fiduciarily sound to execute trades in wide spreads overnight. Market makers need to secure sufficient inventory to hold overnight—but the supply pipeline remains thin. Thus, the initial dynamic is likely to unfold as follows: exchanges open; some market makers and retail brokers offer limited overnight access only for popular names; large institutions will continue to focus on regular hours and periods of high liquidity. “Open” does not mean “institutions are trading all night.” ✅ Is this bullish for crypto? Structurally, yes—but it won’t immediately push prices higher. One of crypto’s weaknesses has been that while spot crypto trades 24/7, institutional access via ETFs and listed equities only moves meaningfully during weekday daytime hours. When Bitcoin crashed over the weekend, IBIT investors faced Monday gaps. When Ethereum surged during Asian trading hours, Bitmine had to wait until U.S. market open. The 23/5 schedule reduces this lag during weekdays. For institutions, crypto becomes less of a “strange asset you can only touch during daylight” and more like an asset that can be hedged and rebalanced alongside equities on similar timelines. The clearest beneficiaries are spot assets: ETFs like IBIT, Strategy (MSTR), and Bitmine (BMNR). Crypto prices and equity prices will now align more closely during weekday nights. Korean daytime traders will also gain new windows to interact with these instruments. Demand previously confined to pre-market and after-hours sessions may now migrate into official exchange sessions. However, avoid misconceptions: Saturdays remain closed. ETF creation/redemption will likely remain centered on regular trading hours. Official closing prices will still be based on regular session data. A price movement in IBIT overnight does not automatically become its NAV for the next day. If retail traders enter first during thin overnight liquidity, institutions may later reverse those moves during daytime sessions—creating a counter-movement.From a broader perspective, Wall Street is beginning to follow the crypto market. The very fact that the stock market is striving to stay awake like crypto signals a shift toward treating cryptocurrency not as a fringe asset, but as a mainstream one—this is a positive development. However, the substance of this利好 is less about “crypto prices will rise from now on” and more about “institutions are now better equipped to gain crypto exposure.” In one line: Starting December 6, U.S. stocks and ETFs will operate on a 5-day, 23-hour-per-day schedule—this includes crypto ETFs, strategies, and Bitmain. Exchanges and clearing infrastructure are ready, but institutional participation during off-hours remains limited. This represents a structural tailwind for crypto in terms of accessibility and price tracking. However, early evening markets may remain volatile, and Saturday gaps will persist. Widening the door is not the same as institutions lining up to walk through it.
