Nasdaq Plans 23-Hour U.S. Stock Trading, Pending Industry Readiness
Nasdaq plans to introduce a 5-hour overnight trading session from 9 p.m. to 4 a.m. ET on Dec. 6, pending industry readiness and regulatory approval. The move aims to accommodate Asia-Pacific investors but raises concerns about liquidity and operational demands. Industry participants discussed the proposal at the WFIC 2026 panel, including representatives from Nasdaq, Cboe, Morgan Stanley, and others. The SEC has already approved a similar 23-hour schedule for Cboe EDGX.

potential upside as market participants price in higher fee revenue from longer trading hours
The new schedule is a primary disclosure and may boost Nasdaq’s fee income, but execution risk and liquidity concerns could temper the move.

Market effects
Extended trading hours could reshape the market‑structure and brokerage‑fee landscape for exchanges and data providers.
