SpaceX Shares Extend Post-IPO Slide Amid Capex Shock
SpaceX (SPCX) investors are learning a painful lesson that has repeated across decades of market history: newly public companies often suffer severe drawdowns before finding their footing. Since its June 2026 debut, SpaceX shares have tumbled approximately 16% in the first month of trading and 4% in the opening week, significantly underperforming the average IPO trajectory tracked by Truist chief markets strategist Keith Lerner.
Historical Context: The IPO Drawdown Playbook
Lerner’s analysis of 31 major IPOs over the past 15 years reveals a sobering pattern: 19 of them (61%) experienced maximum drawdowns exceeding 50% during their first year as public companies. The most extreme case was Robinhood (HOOD), which collapsed 90% from its peak. SpaceX’s current 46% drawdown from its $225 record high already surpasses the average first-year decline of 55%, suggesting the stock may not have found a bottom yet.
Earnings Revelation Sparks Capex Concerns
The latest selloff accelerated after SpaceX’s inaugural earnings report revealed second-quarter capital expenditures of $18.4 billion—triple Wall Street’s $6 billion estimate. Management signaled that Q3 and Q4 capex could remain at similar levels, implying a full-year spend of roughly $65 billion versus the $50 billion consensus. While revenue of $7.8 billion and EBITDA of $3.5 billion both beat estimates (driven by $14 billion in AI cloud services contracts), the market punished the stock for the aggressive spending trajectory and lack of formal guidance.
Valuation Debate: Generational Opportunity or Money Burner?
B. Riley chief markets strategist Art Hogan framed the dilemma on Yahoo Finance’s Opening Bid: “I think it’s pretty difficult to call something a generational opportunity that’s trading at 77 times sales right now. Starship had 12 or 13 test flights. And that seems to be moving at pace. But it’s a money burner.” Elon Musk countered on the earnings call, projecting a $100 billion revenue run rate by end of 2026 and $1 trillion by 2030—pulling forward the prior 2031 target with a “non-zero chance” of hitting it in 2029.
Starlink and Compute Leasing: The Revenue Engine
While Starlink subscriber growth exceeded expectations, analysts note it hasn’t moved the needle materially. Currently, SpaceX’s primary revenue driver is leasing excess compute capacity for AI workloads—a business model more akin to a cloud provider than a traditional space launch company. This dependency on AI capex cycles from hyperscalers introduces concentration risk that the market is still pricing in.
Key Takeaways for Investors
- Historical IPO data suggests SpaceX could face further downside before stabilizing.
- Aggressive capex ($65B implied) creates near-term free cash flow uncertainty.
- Valuation at 77x sales requires flawless execution on Starship and Starlink monetization.
- Revenue concentration in AI compute leasing ties fortunes to Big Tech spending cycles.
Frequently Asked Questions
1. Why do most IPOs experience large drawdowns in their first year?
Newly public companies often debut at peak optimism with inflated valuations. As lock-up expirations increase supply and reality tempers growth expectations, price discovery forces a re-rating. The 61% historical frequency of >50% drawdowns reflects this systematic over-optimism at listing.
2. Is SpaceX’s $65 billion capex plan sustainable?
Sustainability depends on Starship launch cadence achieving orbital refueling and rapid reuse targets to slash marginal launch costs. If Starship reaches $10M/launch (vs Falcon 9’s ~$60M), the economics improve dramatically. However, execution risk remains high given only 12-13 test flights to date.
3. How does AI compute leasing affect SpaceX’s risk profile?
Leasing excess Starlink/satellite compute to AI hyperscalers creates a high-margin revenue stream but concentrates counterparty risk. If Microsoft, Google, or Amazon reduce AI infrastructure spending, SpaceX’s highest-margin revenue could evaporate quickly—unlike diversified launch contracts.
