The rally, driven by retail demand, options trading, and a low float structure, has lifted the stock nearly 58% above its IPO price. SpaceX's recent acquisition of AI coding tool developer Anysphere for $60 billion has further fueled investor enthusiasm.", "body_md": "# SpaceX shares rise 11%, flip Amazon to become fifth largest company by market cap\n\nSPCX is now up nearly 58% from its IPO price as retail demand, options trading and a low float structure push SpaceX past Amazon by market value.\n\nSpaceX shares rose more than 11% Tuesday morning, extending a rally that has pushed the stock into the top tier of global public companies less than a week after its record IPO.\n\nSPCX was recently trading near $213, up about 42% from its $150 opening trade and nearly 58% above its $135 IPO price. The stock traded as high as $225 in early action after strong after hours demand on Monday.\n\nThe move pushed SpaceX’s implied market value above Amazon’s, making Elon Musk’s rocket, satellite, and AI company the fifth largest public company by market cap, according to CompaniesMarketCap [data](https://companiesmarketcap.com/). SpaceX is now valued near $2.8 trillion, compared with Amazon’s roughly $2.7 trillion market value.\n\nSpaceX is also closing in on Microsoft. At a roughly $2.8 trillion valuation, the company is about $132 billion below Microsoft’s $2.93 trillion market cap.\n\nThe latest leg higher comes as retail demand continues to dominate the trade. Retail investors bought almost as much SpaceX stock in the first two sessions as they bought across the entire US market last week, [according](https://sg.finance.yahoo.com/news/spacex-stock-gains-for-third-day-amid-retail-buying-frenzy-105408630.html) to Yahoo Finance.\n\nOptions trading also began Tuesday, adding a new layer of volatility to one of the most heavily watched listings in years. Reuters [reported](https://www.reuters.com/business/options-spacex-shares-start-trading-2026-06-16/?utm_source=chatgpt.com) that more than 675,000 SpaceX options contracts traded by mid morning, with activity heavily concentrated in calls.\n\nThe rally is being amplified by the stock’s limited float. SpaceX sold only a small portion of its shares in the IPO, leaving less than 5% of its stock available for public trading. That low float structure can intensify price moves when demand rises faster than available supply.\n\nThe move also comes as SpaceX pushes deeper into AI. The company [agreed](https://cryptobriefing.com/spacex-acquire-cursor-developer-anysphere-60-billion-all-stock-deal/) to acquire Anysphere, the developer of Cursor, in a $60 billion all stock deal, giving Musk’s company a major foothold in AI coding tools after its earlier combination with xAI.\n\nSpaceX is now trading less like a newly public stock and more like a mega cap momentum vehicle. Retail demand, options activity, low float dynamics and AI dealmaking have combined to turn SPCX into one of the market’s most crowded trades days after its debut.\n\n**Disclosure:** This article was edited by Estefano Gomez.
