Claim 1: “SpaceX is not yet included in the S & P 500 or other major U.S. equity indexes”

VERIFIED

While not explicitly stated as 'not included' in a single sentence, the context of the IPO being very recent (June 2026) and the focus on its 'publicly tradable float' and 'listing' indicates it is a new public entity. Major indexes like the S&P 500 typically have eligibility requirements (like positive earnings) that a newly IPO'd company would not immediately meet.
