SpaceX's rocket-launch business is the engine that powers its entire enterprise, but investors may be getting ahead of themselves on the company's other big bets, according to a new note from MoffettNathanson Research.
The analyst firm, known for its deep dives into telecom and space sectors, argues that SpaceX's near-dominant position in the launch market creates a powerful 'flywheel' effect: lower costs, faster iteration, and the ability to open new markets. However, it warns that the market may be pricing in too much upside from Starlink and other future projects.
The Launch Flywheel
MoffettNathanson's core thesis is that SpaceX's lead in rocket launches is the foundation for everything else. By reusing rockets and scaling production, the company can cut costs and improve reliability faster than competitors. This, in turn, allows it to win more launch contracts, further driving down costs and funding research into new technologies.
This dynamic creates 'long-term options' for SpaceX, the firm says. A lower cost of access to space could eventually enable new products and markets—from orbital data centers to point-to-point Earth transport—that are currently uneconomical. The launch business acts as the flywheel that makes those future bets possible.
SpaceX's recent inclusion in the Nasdaq-100 index, which triggered billions in index fund buying, underscores its growing stature in the public markets. The company's stock has surged since its IPO, reflecting investor enthusiasm for its potential.
Starlink: Not a Universal Solution
But MoffettNathanson pushes back on the idea that Starlink, SpaceX's satellite internet constellation, will become a dominant global broadband provider. The firm describes Starlink as best suited to low-density rural and semi-rural areas, rather than a universal replacement for ground-based fiber or cable networks.
In dense urban areas, where demand is highest, Starlink's capacity is limited by physics and spectrum. The firm notes that terrestrial networks will likely remain cheaper and faster for most city dwellers. While Starlink has carved out a valuable niche—serving remote homes, ships, and aircraft—its total addressable market may be smaller than some investors assume.
This is a key distinction for everyday investors. If Starlink's growth is capped, the revenue and profit expectations baked into SpaceX's valuation may be too high. The company's other speculative ventures, such as orbital data centers or Mars colonization, are even further from generating cash flow.
What It Means for Investors
For investors holding SpaceX stock or considering it, the MoffettNathanson note offers a cautionary perspective. The launch business is real and profitable, but the 'next act' excitement may be overdone.
SpaceX's valuation already reflects a premium for its future potential. If Starlink or other projects fail to meet those lofty expectations, the stock could face pressure. The firm's analysis suggests that investors should focus on the launch business as the core value driver, rather than betting on speculative moonshots.
This is not a recommendation to buy or sell, but a reminder to look under the hood. As with any high-growth stock, understanding where the revenue actually comes from—and how realistic the growth story is—matters more than the hype.
SpaceX's launch dominance is real, and it gives the company a powerful competitive advantage. But the market may already be pricing in a future that is far from guaranteed. For everyday investors, the lesson is to separate the proven engine from the unproven dreams.
