SpaceX IPO Setback Dampens Space Stocks as S&P Rule Freeze Takes Effect

Space stocks slipped overnight after S&P Dow Jones Indices said it would not change eligibility rules for the S&P 500, keeping SpaceX out of the index despite hype around its megacap IPO. The SpaceX IPO is set to price on June 11 at $135 per share for about 555.6 million shares, valuing the company around $1.77–1.8 trillion, though it posted a $4.94 billion net loss in 2025. Nasdaq has revised some fast-entry rules for large IPOs, but S&P’s decision removes a key catalyst for passive-buying ahead of SpaceX’s trading debut the next day. Retail sentiment on space stocks, tracked on Stocktwits, has been mixed as investors weigh the IPO’s potential impact on the sector.
