SpaceX shares fell as much as 4.7% Wednesday, marking the first decline since the company's blockbuster debut that vaulted it past Amazon as the world's fifth-largest stock. The drop erased early gains and threatens to push the rocket maker back below Amazon in market-value rankings, ending a three-day rally that lifted shares nearly 50% above their $135 IPO price.

Retail investors drove intense buying pressure, with SpaceX becoming the most-purchased stock daily since going public, matching combined demand for Nvidia, Alphabet, Amazon, Meta, and major ETFs. Only 4.2% of total shares floated on day one, creating artificial scarcity that amplifies price swings. Analysts at Founder Funds view the pullback as temporary noise rather than fundamental weakness.

Options trading launched Tuesday with over 1.7 million contracts changing hands, as put volume reached 44% by day's end. Investor Michael Burry noted bearish options appear overpriced currently. The volatility coincides with the Fed's first rate decision under Chairman Kevin Warsh, adding macro uncertainty to the mix.

Nasdaq's rule changes could trigger forced buying if SpaceX joins major indexes, though S&P opted against fast-tracking new IPOs. Portfolio managers suggest passive exposure through index funds offers safer entry than direct stock purchases during this turbulent period.
