SpaceX’s $75 Billion IPO Is Grabbing Headlines—But the Smarter Bet May Be the Companies Behind It

The narrative writes itself: the largest IPO in history, a $75 billion capital raise, and a valuation approaching $1.7 trillion. SpaceX, long the most anticipated listing in global markets, has finally opened to public investors—triggering a wave of retail demand and comparisons to the biggest technology debuts of the past two decades.

But beneath the excitement, the fundamentals raise a more difficult question: is this where smart money is deploying capital – or exiting into liquidity?

At current implied levels, SpaceX is trading at a valuation multiple that far exceeds traditional aerospace, telecom, and even most high-growth technology peers. Estimates suggest revenue multiples stretching into territory that assumes near-flawless execution across multiple unproven markets—from satellite broadband to orbital compute.

That may ultimately prove justified. But history offers a consistent pattern: in frontier booms, early infrastructure beneficiaries often outperform the headline names.

The 19th-century gold rush did not create the most wealth for those mining gold—it created it for those supplying the tools.

If space is entering its commercial scaling phase, the same logic applies.

Rather than focusing solely on SpaceX, a more diversified approach looks at the ecosystem forming around it—companies providing critical components, services, and indirect exposure to its growth.

Some are well known. Others remain largely overlooked.

Gilad (likely Gilat Satellite Networks) is one such example. The company develops satellite communication equipment, including ground-based amplifiers and networking systems that enable connectivity between satellites and terrestrial infrastructure. While exact contract figures fluctuate, satellite operators—including those supporting LEO constellations—depend on this layer of hardware. As Starlink expands, demand for ground infrastructure is likely to scale alongside it.

STMicroelectronics represents another, more established beneficiary. The company supplies semiconductor components used across a wide range of industrial and communications applications. While it is not accurate to attribute all Starlink hardware to a single supplier, STMicro has exposure to connectivity and power management chips that benefit from rising satellite terminal production. Growth in user terminals—rather than satellites themselves—may prove a more consistent revenue driver.

Iridium offers a different angle: network monetisation. SpaceX has launched satellites for Iridium under prior agreements, highlighting its role as a launch provider rather than a direct revenue partner. The broader takeaway is that established satellite operators continue to rely on SpaceX for deployment, reinforcing its position as core infrastructure. However, Iridium’s revenues are independent and tied to its own subscriber base, not directly to Starlink.

Intuitive Machines sits closer to the emerging lunar economy. As a NASA contractor under the Commercial Lunar Payload Services (CLPS) program, it is tasked with delivering payloads to the Moon. These missions frequently rely on SpaceX launch capabilities. While contract values have reached into the hundreds of millions, future revenue growth depends heavily on sustained government funding and mission success rates.

Archer Aviation introduces a more speculative link. The company is developing electric vertical takeoff and landing (eVTOL) aircraft, with partnerships including United Airlines. While satellite connectivity—including Starlink—could enhance in-flight systems, integration is not yet standard across fleets. The investment case here is less about SpaceX dependency and more about broader next-generation mobility.

For investors seeking indirect exposure to SpaceX itself, vehicles such as Destiny Tech100—a publicly listed fund holding private technology stakes—offer one pathway. However, portfolio weightings and valuations fluctuate, and such exposure comes with its own liquidity and discount risks.

Alphabet remains the most credible indirect beneficiary. Its $900 million investment in SpaceX in 2015—alongside Fidelity—was widely reported, although the exact ownership percentage has never been fully disclosed publicly. Any mark-to-market valuation today would depend on private pricing assumptions, but the strategic alignment—cloud, AI, and connectivity—remains relevant.

What ties these companies together is not equal dependence on SpaceX, but varying degrees of exposure to the infrastructure layer underpinning the space economy.

And that distinction matters.

Buying SpaceX at peak attention may offer long-term upside—but it also concentrates risk in a single, highly priced asset. By contrast, the broader supply chain captures growth across multiple vectors: hardware, semiconductors, launch services, and adjacent mobility markets.

The reality is that the commercial space sector is no longer a single-company story. It is an ecosystem—and ecosystems tend to distribute value more widely than headlines suggest.

For investors, the opportunity may not lie in chasing the most visible name but in identifying where the economic dependencies truly sit.

Because in every gold rush, the winners are rarely just the ones digging.
