NASDAQ: SPCX’s Thin Float Faces Its First Real Test—Why Anthropic and OpenAI Are Watching
SpaceX traded at $178.35 at 5:13 a.m. EDT Monday, down 3.59% from Thursday’s close and extending a two-session retreat. The market-structure explanation is more compelling than a fresh operating trigger: investors are repricing the scarcity premium embedded in its record IPO before a key index review. The stock is 21.0% below Tuesday’s $225.64 intraday high but still 32.1% above its $135 offer price. That reversal is Wall Street’s first live test of whether a mega-cap issuer can float less than 5% of its implied equity, create benchmark demand and preserve orderly price discovery—the setup Anthropic and OpenAI may try to replicate.
