# SpaceX IPO: Officially added to S&P 500 in 2026?

Live · $28,345 traded · listed on Polymarket

## About

The S&P 500 undergoes quarterly reconstitution on the third Friday of March, June, September, and December.

This market will resolve to "Yes" if S&P Global Inc. announces that SpaceX will be added to the S&P 500 index by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No."

An announcement from S&P will qualify for a "Yes" resolution, regardless of whether the listed company has actually been added to the S&P 500 index by the resolution date.

The primary resolution source will be official announcements from S&P Global Inc. (https://www.spglobal.com/en/press/press-release).
