Shares of companies such as Eutelsat, SES, and Germany’s OHB have surged as investors search for publicly traded ways to gain exposure to the rapidly expanding space economy. In one trading session following IPO headlines, Eutelsat rose about 16%, OHB roughly 11%, and SES around 2–3% on European exchanges.

The reaction highlights a broader shift in how markets think about space: less as a niche aerospace industry and more as critical global infrastructure.

The “SpaceX Effect” on Public Markets

SpaceX has dominated commercial launch and satellite services for years, but it has remained private. That has created a gap in public markets: investors interested in the space sector have had limited ways to participate directly.

News that the company filed a confidential draft registration with the U.S. Securities and Exchange Commission ahead of a possible IPO—potentially the largest ever—has changed that dynamic.

If markets ultimately accept a valuation above $1 trillion, it could establish a powerful new benchmark for the industry. Analysts and investors often value companies relative to comparable peers, so a trillion‑dollar space company could cause a sector‑wide repricing of satellite operators, launch providers, and space‑technology manufacturers.

Because SpaceX shares are not yet publicly available, investors are rotating into listed companies seen as “SpaceX‑adjacent” exposure, including European satellite firms.

Why European Satellite Companies Are Moving

European firms like Eutelsat, SES, and OHB operate in different parts of the space value chain—satellite communications, satellite manufacturing, and space systems. But they are among the few pure‑play space companies listed on major exchanges.

That makes them natural stand‑ins for investors who want exposure to the space theme before the SpaceX listing.

The surge reflects several expectations:

• A SpaceX IPO could validate the long‑term economic potential of satellite networks and launch services.
• Investors may anticipate higher valuation multiples across the sector if the market begins to treat space companies more like infrastructure platforms than traditional aerospace firms.
• Retail and thematic investment flows into "space economy" funds could expand once a flagship public company sets a clear benchmark.

However, the businesses themselves are not identical. Legacy satellite operators, for example, still rely heavily on geostationary communications satellites, while SpaceX’s Starlink focuses on massive low‑Earth‑orbit (LEO) constellations.

Defense Spending Is Strengthening the Narrative

The market enthusiasm is not occurring in a vacuum. Space systems are increasingly tied to defense, communications security, and intelligence, which are all seeing rising government investment.

European defense spending has surged in recent years. EU member states spent about €343 billion on defense in 2024—up 19% from the previous year—with estimates reaching roughly €392 billion in 2025.

Global data shows the same trend: military spending in Europe rose about 14% in 2025, contributing to record worldwide defense expenditures.

This matters for space companies because satellites support many of these capabilities, including:

• secure communications networks
• surveillance and Earth observation
• navigation and targeting systems
• resilient space‑based infrastructure

As governments treat orbital systems as strategic assets, investors increasingly view satellite operators and manufacturers as defense‑adjacent infrastructure providers rather than speculative technology plays.

Artemis II and the Symbolism of a New Space Era

Another factor boosting sentiment is renewed momentum in human space exploration.

NASA’s Artemis II mission, launched in April 2026, carried four astronauts on a roughly 10‑day crewed flight around the Moon—the first crewed mission beyond low Earth orbit in more than 50 years.

While missions like Artemis II do not directly increase revenue for most commercial satellite operators, they reinforce a powerful narrative: that space exploration is entering a long‑term, multi‑decade investment cycle involving governments and private companies.

For markets, that symbolism matters. High‑profile missions signal sustained political and financial commitment to space programs, which can translate into contracts, infrastructure projects, and industry expansion.

Why the Rally Might Not Last

Despite the excitement, many analysts caution that the rally is largely narrative‑driven rather than fundamental.

Key caveats include:

• Business differences: European satellite companies operate very different models from SpaceX’s integrated launch‑plus‑internet platform.
• Unchanged fundamentals: The IPO itself does not directly improve revenue, debt levels, or contract pipelines for these firms.
• Speculative flows: Some of the buying reflects thematic investing and momentum around the "space economy."

In other words, the surge may reflect valuation expectations rather than immediate financial improvements.

What Investors Are Really Betting On

The excitement surrounding SpaceX’s potential IPO is less about one company and more about a broader reclassification of the sector.

If the market ultimately values SpaceX in the trillion‑dollar range, it would send a strong signal that space infrastructure—launch systems, satellite networks, and orbital data platforms—is becoming as economically central as telecom or cloud computing.

For now, the surge in European space stocks shows how quickly that idea is spreading through financial markets—even before the IPO itself happens.

The real test will come when the roadshow begins and investors decide whether the space economy truly deserves infrastructure‑scale valuations.
