Cboe Launches Extended Options Sessions for 29 Products

For decades, the U.S. options market has kept roughly the same rhythm as the stock market it tracks: it wakes up with the opening bell and goes quiet at the close. On Monday, October 19, 2026, Cboe Global Markets began changing that rhythm. According to the company’s announcement, it launched new pre-market and post-market trading sessions for select single-stock and ETF options.

The first day is deliberately modest in scope. It’s a pilot-sized rollout, and it’s worth watching for how far it spreads.

Key takeaways

• Cboe Global Markets launched extended pre- and post-market sessions for select U.S.-listed options on October 19, 2026.
• Trading began with options on 24 single stocks and 5 ETFs, or 29 products in total.
• Cboe says several global brokers are supporting the launch.
• The company frames the change as broader access to U.S.-listed options. Further expansion of the product list is the main thing to watch.

What Cboe launched

Cboe, based in Chicago, said the new sessions sit outside regular trading hours. They give market participants a window to trade options before the open and after the close. The company described the goal as more access to U.S.-listed options.

The initial lineup is 24 single stocks and 5 ETFs. Cboe has not been described as extending hours across its whole options menu. This is a selective start, and that’s typical when an exchange adds a new trading window to a product class that has traditionally had one fixed session.

Cboe also said several global brokers are supporting the launch. Broker readiness often decides whether a new session matters in practice. An exchange can open the window, but investors can only use it if their broker routes orders into it.

Why it matters for markets

Options tend to react to news. Earnings releases, economic data and corporate announcements often land outside regular hours, and the underlying shares may already be trading in extended sessions. An options market that is closed while the stock moves leaves a gap. Extended sessions are a way to narrow it.

The launch also matters for investors outside the U.S. Cboe specifically highlighted global broker support. Time zones make a pre-market or post-market window more convenient for participants who are awake when New York is not.

The real test of extended-hours options isn’t launch day. It’s whether liquidity shows up in the 29 products, and whether the list grows.

That is the central question for any new session. Options contracts are more fragmented than shares, with many strikes and expirations. Participation can be thin outside regular hours, which affects how tight and reliable quotes are. Cboe’s announcement doesn’t offer data on that, and it’s too early for anyone to have any.

Who is affected

Market makers, brokers and active options traders are the most direct audiences. Brokers have to decide how to present the new sessions to clients. Market makers have to decide how much risk to quote when the underlying market is less liquid. Retail users will need clear disclosure of what is and isn’t available, since only 29 products are eligible at the start.

Listed companies and ETF sponsors have an indirect stake. Options availability is part of how investors engage with a stock or fund, and extended access could become one more feature that issuers and their advisers consider when thinking about trading life after a listing.

What to watch next

Three things bear watching. First, whether Cboe adds more single stocks and ETFs to the extended sessions. Second, whether more brokers join the initial group. Third, whether the exchange or brokers release usage and liquidity figures that show if the new hours are being used.

Also on the filing wire

Separately, EDGAR full-text searches for uplisting language surfaced Form 8-K filings from Non Invasive Monitoring Systems Inc. (NIMU), filed October 19, and Private Bancorp of America, Inc. (PBAM), filed October 16. A search match alone doesn’t establish what either company is planning, so readers should check the filings themselves for any listing developments.
