SpaceX was supposed to rocket into the S&P 500 shortly after its anticipated June 2026 IPO. Instead, it’s looking at a minimum one-year wait in the penalty box, thanks to the index’s gatekeeper refusing to bend the rules for mega-cap newcomers.
S&P Dow Jones Indices announced on June 4 that it would keep its existing eligibility criteria intact for the S&P 500 and other major indexes. The decision came after a formal consultation process that explored whether mega-cap IPOs deserved a faster track into the index.
The profitability problem
Here’s the thing about the S&P 500: you can’t just be big. You have to be profitable. The index requires GAAP profitability in the most recent quarter plus positive cumulative earnings over the trailing four quarters. It also mandates a 12-month public trading history and a minimum investable weight factor of 10%.
SpaceX clears the “big” bar with ease, but the profitability requirement is where things get uncomfortable. The company reported a net loss of $4.94 billion against $18.67 billion in revenue for 2025.
