SpaceX (NASDAQ: SPCX) briefly surpassed Amazon.com in market capitalization on June 16 as investors continued piling into shares following the company’s record-setting initial public offering, according to a Reuters report. Shares of Elon Musk’s rocket, satellite and artificial intelligence company climbed as much as 10%, pushing its valuation above $2.7 trillion and, at one point, ahead of both Amazon and Microsoft among the world’s most valuable companies.
The surge was fueled in part by the launch of options trading in SpaceX shares and growing investor enthusiasm surrounding the company’s expanding presence in space technology, communications and artificial intelligence. Reuters noted that analysts expect additional buying pressure as SpaceX is positioned for inclusion in major equity indexes, including the Nasdaq-100, FTSE Russell and MSCI indexes later this month. The stock’s rapid ascent follows last week’s historic IPO, which raised approximately $75 billion and valued the company at $1.77 trillion, the largest public offering on record.
As of 11:30 a.m. ET on June 16, 2026, SpaceX stock was trading at approximately $211.63, up about 10%, with a market capitalization exceeding $2.7 trillion. The milestone underscores SpaceX’s transformation from a private space startup to one of the most valuable publicly traded companies, with businesses spanning aerospace, satellite internet via Starlink, defense contracts and AI initiatives.
The company’s rapid valuation growth reflects investor confidence in its dominant position in the space economy and its potential to disrupt multiple industries. Inclusion in benchmark indexes later this month is expected to drive additional demand from institutional investors and index funds, potentially further boosting the stock price. However, the volatile trading session highlights the speculative nature of the stock, which has more than doubled since its IPO.
