SpaceX stock falls for a second day, slipping below Amazon in market cap as post-IPO excitement wanes; traders expect significant movement next week.

SpaceX's stock fell for a second consecutive day, dropping 6% on Thursday to close at $178.50, which lowered its market cap to $2.37 trillion, below Amazon's $2.63 trillion. Traders anticipate significant volatility next week as options pricing suggests potential swings of 10%.

SpaceX's stock has experienced a significant decline, falling over 6% on Thursday, following a record-breaking IPO last week. The stock's market cap has now slipped to $2.37 trillion, placing it below Amazon's $2.63 trillion.12

After a surge of 15% earlier in the week, the stock has seen a total drop of 20% since reaching a high of $225 on Tuesday. This decline has erased approximately $620 billion from SpaceX's market value, which had briefly positioned it as the world's fourth-largest company.7

Analysts attribute the selloff to concerns over a $60 billion all-stock acquisition of AI coding startup Cursor, which has raised fears of dilution among investors. Morningstar analysts have lowered their fair value estimate for SpaceX to $62 from $63, citing this dilution.9

Despite the recent downturn, retail investors had aggressively purchased SpaceX shares, totaling $369.8 million in the first three sessions post-IPO, significantly outpacing investments in Nvidia. However, trading activity has since cooled, with only $9.1 million in net purchases noted on Thursday.

Looking ahead, options pricing indicates that SpaceX's stock could swing as much as 10% in either direction next week, with potential highs of $204 and lows of $166. The stock may also be added to major indexes, which typically boosts prices as funds buy shares in anticipation.45

“Given the magnitude of the IPO and the strong initial performance, some degree of profit-taking is not surprising,” said IPOX Schuster analyst Kat Liu.

Elon Musk's net worth has also taken a hit, dropping by $67.8 billion to approximately $1.2 trillion.
