Effective trade date August 25, 2025, Cboe Options Exchange (C1) will begin listing P.M.-settled, cash-settled options on the S&P 500 Equal Weight Index.

S&P 500 Equal Weight Index Options are cash-settled options based on 1/10th of the S&P 500 Equal Weight Index (EWI), the equal-weight version of the S&P 500 Index. The underlying index includes the same constituents as the capitalization-weighted S&P 500 Index, but each constituent in the S&P 500 EWI is allocated a fixed weight, or 0.2% of the index total at each quarterly rebalancing.

Upon the effective date, P.M.-settled S&P 500 Equal Weight Index Options will be listed on C1, residing exclusively on Matching Unit 31. Trading for expiring SPEQW options will close at 4:00 p.m. ET on the expiration date.

The exercise of SPEQW options will result in delivery of cash on the business day following expiration. The exercise-settlement value, SPEQX, is calculated using the closing sales price in the primary market of each component security on the expiration date. The exercise-settlement amount is equal to the difference between the exercise-settlement value and the exercise price of the option, multiplied by $100.

Cboe may list up to six standard monthly and six weekly SPEQW option expirations, and up to ten SPEQW LEAPS monthly expirations to expire 12 to 180 months from the date of issuance.
