SpaceX roared past Amazon's market valuation on Tuesday and briefly topped that of Microsoft, rapidly scaling the list of the world's most valuable companies on a topsy-turvy trading day fueled by frenzied action in the firm's newly listed option contracts.
SpaceX shares were up 10% at $211.63 after trading as high as $225.64 during intraday trade—jumping more than 66% above the $135 IPO price—giving Elon Musk's company a market value exceeding $2.75 trillion—nearly $1 trillion above its record IPO valuation set last week.
