Key Points
-
SpaceX’s launch dominance gives Starlink a scale advantage unmatched by most satellite rivals.
-
Starlink remains profitable, though falling average revenue per user (ARPU) signals potential margin pressure as growth enters lower‑priced markets.
-
Artificial intelligence compute may become SpaceX’s next major growth engine, yet the business continues to incur significant losses and capital expenditures.
Space Exploration Technologies (NASDAQ: SPCX) has become one of the most prominent post‑IPO stories of 2026. The company priced its initial public offering at $135 per share, opened for trading at $150, and closed its first trading day at $160.95. Investors who received shares at the IPO price secured a gain of roughly 19% by the close of day one. The stock closed at nearly $201.80 on June 16, almost 50% above its IPO price, elevating SpaceX’s market value to about $2.6 trillion.
The critical question now is whether SpaceX stock can sustain its sharp post‑IPO rally, and whether the move is driven by robust business fundamentals or investor enthusiasm. Shares slipped slightly on Thursday, but the stock is still showing solid gains from its IPO price.

Robust Growth Story
SpaceX maintains clear leadership in rocket launches. In 2025, the company conducted 161 commercial launches, capturing 82% of the U.S. commercial launch market and more than 80% of all satellite and spacecraft weight sent into orbit worldwide.
SpaceX not only delivers launches for external customers but also leverages its own rockets to accelerate the expansion of Starlink, its satellite‑internet business, at a lower cost. Frequent launches enhance coverage, add capacity, and serve both commercial and government clients, outpacing rivals that lag in reusable rocket and satellite scale.
Starlink generated $11.4 billion in revenue and was SpaceX’s sole profitable business segment in 2025. The service had 10.3 million subscribers across 164 countries as of March 31, 2026.
However, Starlink’s average revenue per user (ARPU) declined from $91 per month in 2024 to $81 in 2025, and to $66 in Q1 2026, suggesting growth is partly driven by lower‑priced markets and cheaper service plans. Investors should monitor whether Starlink can sustain growth without eroding margin.
Upside Potential with High Execution Risk
SpaceX earned $3.2 billion in AI revenue in 2025, a 22.2% year‑over‑year increase. In May 2026, the company secured a deal with Anthropic to supply compute capacity for $1.25 billion per month through May 2029. While the initial capacity is priced lower, SpaceX is ramping up throughput in mid‑2026.
Nevertheless, the AI expansion exposes SpaceX to significant execution risk. Although Starlink remains profitable, AI initiatives are consuming cash faster than they generate earnings. In 2025, the company reported a $4.9 billion net loss, $6.4 billion in AI operating losses, and $12.7 billion in AI capex. Q1 2026 AI capex alone reached $7.7 billion. SpaceX ended the quarter with $29.1 billion in debt, including a $20 billion bridge loan due for repayment by September 2027, with a potential two‑ to three‑month extension.
At a $2.6 trillion market cap, Wall Street already assumes robust execution across SpaceX’s dominant Starlink business and a substantial AI infrastructure opportunity. The stock may still rise as investor demand remains strong and index‑related buying provides additional support.
Long‑term investors must see evidence that Starlink can sustain ARPU and that AI losses shift toward profitability.
Considerations Before Investing in Space Exploration Technologies
Before purchasing Space Exploration Technologies shares, evaluate the company’s growth prospects, margin dynamics, and execution risk, particularly in the AI segment. While the stock has demonstrated strong upside since its IPO, prudent assessment of its long‑term fundamentals is essential.
