SpaceX shares slide 5% to $147 in June 23 premarket, dipping below $150 debut open

SpaceX shares fell 5% to $147 in premarket trading on June 23, slipping below their first-day opening price of $150. The move wiped about $40 billion in market value in a single session and more than $60 billion over three days. Over the same period, Nasdaq 100 futures dropped 2.6% and S&P 500 futures fell 1.4% after reports that South Korea’s SK Hynix and Samsung Electronics paused AI chip capacity expansion. SpaceX is not publicly listed, but its secondary-market trading has been viewed as a barometer of cooling sentiment across AI-related stocks.
