SpaceX shares traded near $135 Thursday after two consecutive days of declines, approaching the fixed price Elon Musk set for the company's March IPO. The retreat erases gains from last week's Nasdaq-100 addition and marks the first meaningful test of the unorthodox pricing mechanism that bypassed traditional Wall Street book-building.
Musk's space and AI enterprise raised north of $200 billion in what became the largest U.S. IPO on record, pricing shares at exactly $135 with no range, no roadshow variance, and no allocation games. The stock traded up to $148 in the days following Nasdaq-100 index inclusion on April 14, as passive funds absorbed roughly $18 billion in forced buying. That premium has now unwound. The fixed-price structure—derided by bankers as amateurish during the listing process—now functions as visible psychological support with no IPO-range ambiguity to cloud investor memory.
The timing matters because SpaceX is the first mega-cap to enter public markets with material exposure to both launch services and frontier AI compute, creating unusual cross-currents. Starlink subscriber growth slowed to 3.2% quarter-over-quarter in Q1 versus 4.7% in Q4 2024, per the first earnings disclosure two weeks ago. Meanwhile, the company's XAI compute division is burning $840 million per quarter building out GPU clusters in Memphis and Central Texas, with revenue contribution still under $110 million. The deceleration in the mature telecom business is arriving faster than the acceleration in the speculative AI business, leaving growth-at-reasonable-price buyers without a clean narrative.
Passive rebalancing also created a technical trap. Nasdaq-100 inclusion forced roughly $18 billion in mechanical buying by tracker funds, front-run by $4-6 billion in event-driven arbitrage ahead of the April 18 effective date. That wave is complete. What remains is a $205 billion market-cap company trading at 19x forward revenue with decelerating subscriber growth, rising capex, and no government contract revenue for another nine months due to Pentagon procurement cycles. The Musk premium is real, but it does not exempt SpaceX from the same multiple compression hitting other infrastructure-as-a-service models when growth rates inflect below 20% annualized.
Allocators should watch two forcing functions over the next sixty days. First, the May 15 earnings call, where management will either raise full-year Starlink subscriber guidance or acknowledge that penetration in Tier 2 markets is slowing faster than expected. Second, the June options expiration cycle, which will be the first with significant open interest after the IPO lockup mechanics expire on May 7. If employee liquidity accelerates post-lockup, the $135 fixed price becomes the line where insider selling either pauses or accelerates, providing a clean signal on internal conviction.
The $135 level now carries more information than typical IPO support zones. Musk set that price in public, refused to adjust it despite banker pressure, and staked credibility on the idea that eliminating price discovery would reduce volatility. If the stock breaks and holds below $135 for more than three sessions, that thesis unravels, and the next support level is structural: the $117 price where pre-IPO secondary markets cleared in February 2025, eight weeks before the listing.
