SpaceX just surpassed Amazon's market cap, overtaking the 31-year-old company on day three of public trading

SpaceX has surpassed Amazon’s market capitalization by day three of public trading, briefly overtaking Microsoft as well, signaling intense investor enthusiasm for the privately held rocket-and-AI company. Musk’s net worth neared $1.27 trillion, a figure that dwarfs peers and underscores the dramatic market frenzy around SpaceX’s IPO and post-listing performance. SpaceX stock has rallied about 62% from its $135 offering price, while Amazon reported $717 billion in revenue and $77.7 billion in profit last year. Retail investors poured roughly $225 million net into SpaceX in the first two days, equating to about 75% of all net single-stock buying.
