May 2026 OpEx Date

The exact May 2026 standard monthly options expiration date, with the surrounding weekly calendar and the ticker-level checks a data workflow should run.

Quick answerLast verified May 7, 2026

Useful for OI concentration, monthly expiration scans, and event studies.

Why May 15 is the May 2026 monthly date

Standard monthly equity and ETF options normally expire on the third Friday of the expiration month. In May 2026, the third Friday is May 15, so that is the monthly OpEx date.

A weekly expiration on May 1, May 8, May 22, or May 29 is a different cycle. Those dates can matter for short-dated scanners, but they should not be labeled as monthly OpEx.

How to use the May date in a scanner or article

Put the direct May 15 answer first, then show the surrounding Friday dates so readers understand what is monthly and what is weekly. That structure matches the search intent without flattening every Friday into the same event.

For an application, the page should map into a listed-expiration lookup. Fetch SPY, QQQ, AAPL, NVDA, or TSLA expirations by ticker, keep May 15 as the monthly label, and only query contracts for dates that the endpoint returns.
