SpaceX IPO Shares Sink Below Offering Price Amid Massive Market-Cap Erosion and Looming Lock-up Releases

On July 28 2026, SpaceX’s publicly traded shares closed about 20 % below the $135 IPO price, extending a decline that has erased more than $1 trillion in market value since the June 16 peak. The stock traded at $107.30 in early trading, roughly 47 % below the June high, and the company’s market capitalization fell from a peak near $3 trillion to about $1.5 trillion.

SpaceX shares fall 20% below IPO price, erase $1.2T in market value

SpaceX debuted in mid-June 2026, pricing its shares at $135 and opening at $150. The float was initially only 4 % of total shares, prompting a fast-track Nasdaq-100 inclusion. The IPO prospectus warned that about one-fifth of 2025 revenue came from federal contracts and that shifts in government funding could materially affect the business. Shortly after the debut, the stock entered a volatile phase as investors questioned whether spending on AI and space projects had outpaced fundamentals.
