Space Exploration Technologies Corp. (SPCX) lost $1 trillion in market value in 30 days. The stock now trades 72% below its IPO peak.
Short sellers now control 32% of SPCX’s float. That is a record for any major US IPO, according to CNBC data.
Elon Musk warned short sellers “won’t survive.” His past battles with short sellers—most notably during Tesla’s 2020 rally—have historically preceded violent squeezes. But the mechanics differ this time.
The selloff began after a failed Starship test on June 14. Regulatory delays followed. A broader tech selloff, driven by rising interest rates, accelerated the decline.
| Metric | Value |
|---|---|
| Peak market cap (May 2026) | $1.4 trillion |
| Current market cap | $400 billion |
| Short interest (% of float) | 32% |
| RSI (14-day) | 18.2 (oversold) |
| Revenue growth (YoY) | 22% |
| Government contract reliance | 68% of revenue |
SpaceX now ranks among the worst IPOs in recent history. The decline exceeds those of Uber (-41% from IPO), WeWork (-90%), and Rivian (-83%).
The bull case rests on Starlink’s profitability. Starlink generated $8.4 billion in revenue in 2025. But the segment remains cash-flow negative after capital expenditures.
The bear case cites unsustainable debt. SpaceX holds $22 billion in long-term debt. Interest payments consumed 34% of operating cash flow last quarter.
Yahoo Finance polled 47 analysts. Only 12 rate SPCX a “buy.” The rest cite regulatory risk, competition from Blue Origin, and China’s rapid space program advances.
Technical indicators flash warning. The stock broke below its 200-day moving average on July 10. Volume spiked 340% on July 18, the day of Musk’s short-seller warning.
History offers parallels. The 2008 financial crisis saw overleveraged positions unwind in weeks. The dot-com bubble saw speculation-driven stocks lose 80-90% of value. SPCX’s current pattern mirrors both.
CNBC reported that short interest surged from 18% to 32% in two weeks. This suggests institutional traders are betting on further downside, not a recovery.
Musk’s warning may trigger a short squeeze. But the structure of current short positions—mostly long-dated options and swaps—makes a violent squeeze less likely than in Tesla’s 2019-2020 run.
MSN’s analysis notes that 78% of SPCX’s float is held by insiders and long-term funds. The remaining 22% is where the battle unfolds.
The key question: buying opportunity or warning? The answer depends on risk tolerance. SPCX’s revenue growth is real but slowing. Its debt load is heavy but manageable. The narrative of space exploration remains intact.
Investors should watch three signals: short interest changes, Starship test results, and Starlink’s cash flow inflection point. Until those clarify, the safest trade is to watch from the sidelines.
