SpaceX shares fall as post-IPO frenzy loses steam

June 18 : Shares of Elon Musk's rockets-to-AI firm SpaceX dropped more than 6 per cent on Thursday, as the post-IPO frenzy that briefly placed it among the top five most valuable companies of the world appeared to fizzle out.

Its shares were last down 6.4 per cent at $179.62, after falling nearly 5 per cent in the last session. Despite the losses, the stock still traded more than 30 per cent above its $135 offering price.

Earlier this week, the market capitalization of SpaceX overtook that of Amazon, momentarily even surpassing that of Microsoft.

If the losses persist, SpaceX's market value of $2.52 trillion would shrink by more than $160 billion on Thursday.

Shares of other U.S. space companies were also down. Rocket Lab and Planet Labs dropped around 3 per cent, while AST SpaceMobile and Intuitive Machines declined around 7 per cent and 3 per cent, respectively.

SpaceX's bankers are preparing to meet investors as early as next week to discuss a bond offering of at least $20 billion, a source said on Thursday, as the newly public company seeks funding for an ambitious and capital-intensive AI expansion.

The company announced on Tuesday that it would buy Anysphere, the startup behind the popular AI coding agent Cursor, for $60 billion in stocks to boost its presence in the lucrative enterprise AI tools market.

Earlier this year SpaceX had acquired Musk's AI startup xAI in a record-setting deal, unifying the entrepreneur's rocket-and-satellite company with the maker of the Grok chatbot.

The rockets-to-AI company's valuation surged past $2 trillion following its blockbuster Nasdaq debut last week. Its shares soared in their first two days of trading before giving up some gains as investors assessed whether the company's rich valuation can be justified by its costly AI push.
