SPX May 2026 Options Expiration Dates
A direct answer for SPX May 2026 expiration searches, with standard SPX and SPXW context separated.
The standard May 2026 SPX monthly expiration is Friday, May 15, 2026. SPXW weekly expirations can exist on other May dates, but standard SPX monthly and SPXW weekly series should be labeled separately because settlement conventions can differ.

Caveat
Settlement
Standard SPX and SPXW settlement conventions are not always identical.
Why SPX and SPXW should not be collapsed
SPX searches often mix the standard monthly index option with SPXW weekly expirations. A useful page should answer the monthly date first, then show how weekly index dates fit around it.
For implementation, treat the root and contract identity as part of the date lookup. A generic Friday calendar is not enough for an index-options workflow that needs the right settlement and contract ticker.
