SpaceX Hits US$350 Billion Valuation, Dominates Aerospace Market

Elon Musk’s SpaceX has reached a market valuation of US$350 billion following its latest round of secondary share purchases, solidifying its position as the most valuable private aerospace company in the world. This milestone comes as SpaceX and its investors participated in a US$1.2 billion stock buyback to support employee liquidity and accommodate new investor interest.

According to CNBC, SpaceX and its investors agreed to purchase shares at US$185 each—an increase of 65% from the US$112 per share rate during the last secondary transaction in September. Bloomberg confirmed that SpaceX would buy approximately US$500 million of those shares directly, while external investors would contribute the remaining US$750 million.

This recent share sale marks a significant leap from SpaceX's June valuation of US$210 billion, representing a 67% increase from that previous high. Musk’s company has routinely executed these share repurchase rounds about twice yearly, allowing employees and other shareholders to liquidate stock holdings.

The soaring valuation places SpaceX ahead of major tech competitors such as ByteDance, the parent company of TikTok, which was recently estimated at US$300 billion during a share buyback of its own. SpaceX’s valuation is comparable to top US defense contractors and would rank among the top 25 companies on the S&P 500 by market capitalization—between Johnson & Johnson and Bank of America, according to data from FactSet.

SpaceX currently leads the US satellite launch industry with its Falcon rockets and is expanding operations through its Starlink internet service, which boasts over five million active subscribers and 7,000 satellites in orbit. Additionally, SpaceX is advancing its Starship project, aiming to develop the next generation of reusable rocket technology with unprecedented scale and capabilities.
