Space Exploration Technologies Corp. (SpaceX; SPCX) shares fell after its first post-IPO Q2 earnings report on Aug. 4, 2026, as investors reacted to sharply higher AI-related capital spending and the impending Aug. 6 lockup expiration that will expand the tradable float.
Earnings, AI Capex, and Outlook
SpaceX reported its first quarterly earnings as a public company for Q2 2026, broadly surpassing Wall Street forecasts for revenue and losses while remaining unprofitable. The company disclosed capital expenditures of about $18.4 billion, with roughly $15.8 billion allocated to AI infrastructure. This represented a roughly 550% year-over-year increase and an 82% quarter-over-quarter rise in spending.
Management said in early Q3 it had contracted an additional $6.7 billion in cloud-services revenue, expected to begin ramping in October 2026. Executives indicated the AI investments could start generating returns within about a year. The company also secured a $1.6 billion U.S. Space Force order for 18 Falcon 9 launches through 2027, adding near-term contracted launch revenue.
Lockup Expiration and Market Reaction
On or about Aug. 6, roughly 911–912 million previously restricted insider and employee shares will become eligible for sale. This tranche represents more than $100 billion of potential supply and could increase the freely tradable float from below about 5% to above about 12%.
Shares reversed earlier gains after the earnings release, falling 10–13% on Aug. 5 as investors digested the scale of AI spending and the looming lockup. Retail investors reportedly bought the dip while institutional investors remained cautious. Short sellers had built positions ahead of the earnings and lockup, with short interest surpassing Tesla’s as traders bet against the high-valuation, high-capex narrative.
Following the initial unlock, smaller rolling releases are expected through October, with a larger tranche two days after Q3 earnings in November, a 180-day unlock in early December 2026, founder-related eligibility in June 2027, and a final float expansion around September 2027.
The combination of heavy near-term AI capital expenditures pressuring free cash flow and a sudden large increase in shares eligible to trade creates a volatile trading environment for SpaceX in the near term.
