Shares of Elon ​Musk’s rockets-to-AI ‌firm SpaceX (SPCX-Q) dropped ​more than 6% 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% at $179.62, after falling nearly 5% in the last session. Despite the losses, the stock still traded more than 30% 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%, while AST SpaceMobile ⁠and Intuitive Machines declined around 7% and 3%, ⁠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.
