Took SpaceX Just 1 Day to Reach a Milestone Tesla Has Never Achieved. Which Elon Musk-Led Stock Is the Better Buy in June?

SpaceX surpassed a major market milestone in June, following Tesla’s December 2025 intraday peak of $498.83 with SpaceX’s IPO closing at a $2.11 trillion market cap after selling 555.6 million shares for $135 each, raising $75 billion. The float is under 5% of total shares, meaning insiders and institutions still own most of SpaceX, potentially driving further upside as insiders sell ahead of the typical 180-day lockup. Tesla trades with a separate, high valuation, but SpaceX’s revenue reached $18.67 billion in 2025 while posting a $4.94 billion net loss, and 2026 consensus estimates project $2.06 per share on about $118.45 billion in sales, yielding a steep 162.4x forward P/E.
