SpaceX Dips Below $150 IPO as $400B Is Erased, Then Rebounds with AI Deal

For the space industry, SpaceX’s IPO turmoil is more than a Wall Street story—it’s a litmus test of how public markets value a company whose ambitions range from satellite internet to Mars colonization. The recent 16% plunge and subsequent recovery near the $150 IPO price reflect a cooling of the initial euphoria and force a hard look at whether SpaceX can fund its capital-intensive projects without diluting shareholders. Meanwhile, the newly announced computing power agreement with AI startup Reflection hints at an emerging revenue stream that could reshape the financial narrative for pure-play space ventures.

SpaceX’s record-breaking IPO on June 12, 2026, sent shares soaring more than 50% above the $150 offering price, briefly catapulting its market capitalization past Amazon and Microsoft and north of $2 trillion. But that euphoria evaporated within days. By Monday, June 22, the stock had cratered 16% in a single session—wiping out roughly $400 billion in market value—and dipping back below the $150 debut level before a modest 5% rebound on Tuesday. The violent swing erased nearly all of the early gains for the average IPO investor and placed the Elon Musk-led space and AI company under a harsh new spotlight.

SpaceX’s record-breaking IPO on June 12, 2026, sent shares soaring more than 50% above the $150 offering price, briefly catapulting its market capitalization past Amazon and Microsoft and north of $2 trillion.

The sell-off did not emerge from a vacuum. Two prior trading sessions had already chipped away at the froth: a 3.6% decline on Thursday, June 18, followed by a 5% drop on Friday, June 19. When the 16% rout hit on Monday, it was the culmination of a rapid repricing as initial retail and institutional exuberance gave way to second thoughts about the durability of SpaceX’s valuation. By the close of the week of June 15, the average buyer who had chased the post-IPO pop was effectively back to breakeven, and the Monday plunge pushed many into loss territory.

Beyond the stark price action, two substantive corporate developments added complexity to the narrative. On the same day as the deepest sell-off, SpaceX disclosed it held $100.8 billion in cash and cash equivalents as of June 19—an enormous liquidity buffer even by the standards of mega-cap tech firms. At the same time, the company announced plans for a senior unsecured notes offering, signaling an intent to raise additional debt capital. Simultaneously, SpaceX revealed a high-profile computing power agreement with Reflection, an open-source AI startup, which will gain access to Musk’s Colossus infrastructure. The deal positions SpaceX not just as a launch and satellite internet provider but as an emerging AI infrastructure powerhouse, potentially creating a new, high-margin revenue stream.

These announcements cut both ways for the investment thesis. The $100.8 billion cash hoard dwarfs the capital needs of the core launch and Starlink businesses, providing a cushion against execution risks and enabling aggressive investment in Starship and Mars ambitions. Yet the notes offering suggests that even this cash pile may not fully cover the grand vision without significant external funding, raising questions about future dilution or leverage. Meanwhile, the Reflection AI deal validates the Colossus infrastructure but also hints that SpaceX may be venturing further from its core aerospace competencies, adding a layer of execution risk in the competitive AI cloud market.
