The CBOE just announced they are planning to add Tuesday and Thursday expirations to the SPX. With the Monday, Wednesday and Friday weeklies they already have, this would make everyday an expiration day.
From email they just sent out:
Cboe Global Markets, Inc. plans to list S&P 500 Index Weeklys options with Tuesday and Thursday expirations in the second or third quarter of 2022, subject to regulatory review.
With these planned new listings, Cboe will offer SPX Weeklys options with expirations on every trading day of the week, providing traders with additional tools to help manage their short-term U.S. equity market exposure and execute trading strategies with even greater frequency, precision, and flexibility.
