SpaceX’s rapid expansion in launch services and satellite broadband is creating a powerful, if indirect, tailwind for a handful of specialized chipmakers. One of the most intriguing beneficiaries is a lesser-known semiconductor name whose rally has turned it into a stealth way to bet on the company’s swelling revenue base. Instead of waiting for a potential SpaceX listing, investors are increasingly looking at this soaring chip stock as a way to tap into the same growth engine.
At the center of that story is Macom Technology Solutions, a focused analog and RF chip designer that has been singled out as a beneficiary of rising demand tied to space infrastructure and advanced communications. Its recent surge has been strong enough that some analysts now frame it as a kind of “picks and shovels” trade on the private space giant’s ambitions, rather than a conventional satellite or launch play.
How Macom became a backdoor bet on SpaceX
I see Macom Technology Solutions as a classic example of how niche semiconductor specialists can quietly become critical suppliers to headline-grabbing platforms. The company designs high‑performance radio‑frequency and optical components that sit deep inside communication systems, from ground stations to satellite links. As SpaceX scales its Starlink constellation and pushes more data through space‑to‑ground networks, demand for precisely this kind of RF and optical plumbing has accelerated, which helps explain why this chip stock is surging and increasingly viewed as a way to participate in SpaceX’s growth without owning the rocket maker itself.
What makes the setup more compelling is that Macom Technology Solutions has explicitly highlighted multiple avenues through which it can capture that demand, including satellite communications, high‑speed optical links and advanced radar. In recent coverage, the stock’s rally has been tied to expectations that these end markets could support a long runway of earnings expansion, with some observers even floating the idea that Macom could be the next hot AI trade as its chips help move and condition data at high speed. One report, Provided by Dow Jones Jan and attributed to By William Gavin, underscored how closely the company’s opportunity set is now linked to the broader space and data‑infrastructure boom, even noting that the stock’s move has been driven by roughly 33 percent gains over a short window as investors reassess its role in the ecosystem.
SpaceX’s swelling valuation and what it implies for suppliers
For any supplier‑driven thesis to hold water, the core customer’s growth story has to be credible, and in SpaceX’s case the numbers are striking. Analysts tracking the private company’s funding rounds and secondary transactions have floated scenarios in which its valuation climbs toward $800 billion as it scales Starlink, deepens its launch backlog and opens new revenue lines in areas like in‑flight connectivity. In one widely cited bull‑case, analyst Swinburne argued that if SpaceX’s valuation did reach $800 billion, the implied upside for investors with indirect exposure through key partners and vendors could be substantial, particularly if the company’s revenue approaches about $15 billion this year as expected in that analysis, even though SpaceX does not disclose its share count.
From my perspective, that kind of valuation framework matters less as a precise target and more as a signal of the scale investors now assign to the business. A company that can plausibly support a multi‑hundred‑billion‑dollar valuation will need a vast and resilient supply chain, especially in semiconductors, where capacity constraints can bottleneck growth. That is why I pay close attention not only to Macom but also to other chipmakers already embedded in SpaceX’s hardware stack. The same Swinburne scenario, discussed in a detailed note on a possible 2026 listing, framed SpaceX’s trajectory as a structural growth story rather than a one‑off IPO pop, which in turn reinforces the idea that suppliers with durable design wins could enjoy years of elevated demand as the company moves toward any potential public offering, as outlined in $800 billion bull‑case discussions.
STMicroelectronics shows how powerful a SpaceX design win can be
If investors want a concrete example of how lucrative a SpaceX relationship can become for a chipmaker, STMicroelectronics offers a useful template. The company, often shortened to STM, is one of Europe’s largest semiconductor manufacturers and has emerged as a key supplier of radio‑frequency components to SpaceX’s Starlink user terminals. Its chips help manage the complex beam‑forming and signal‑steering tasks that allow flat‑panel antennas to track satellites in low Earth orbit, a capability that is central to Starlink’s promise of high‑speed broadband in remote locations across Europe and beyond.
The scale of that partnership is already visible in shipment figures. STMicroelectronics, identified in some financial reporting as STMPA, Financials, has disclosed that it has delivered more than 5 billion radio‑frequency antenna chips for use in Starlink terminals and that it expects shipments of those Starlink chips to potentially double by 2027. That trajectory illustrates how a single high‑growth platform can transform a product line into a multi‑billion‑unit franchise, and it also shows why investors are so focused on which chipmakers have secured design wins inside SpaceX hardware. When I look at Macom’s positioning in RF and optical components, I see a company that could follow a similar path if its parts become standard in ground stations or future satellite payloads, much as STMPA has done in the antenna domain.
Why Macom’s niche could matter as Starlink and space data scale
Macom’s opportunity is not just about selling more chips into a single customer, it is about sitting at the intersection of several structural trends that SpaceX is helping to accelerate. Starlink’s expansion is driving demand for high‑throughput ground infrastructure, from gateway stations that connect satellites to terrestrial fiber, to enterprise‑grade terminals that integrate satellite backhaul into 5G and private‑network deployments. Those systems rely heavily on precision RF amplifiers, filters and optical transceivers, all areas where Macom Technology Solutions has deep expertise and a broad catalog. As more data flows through these networks, the value of high‑performance analog and mixed‑signal components tends to rise, since they determine how efficiently signals can be transmitted, received and converted.
At the same time, SpaceX’s work is blurring the line between space and terrestrial telecom, which opens additional doors for a company like Macom. The same RF front‑end technologies that support satellite links can be adapted for advanced radar, defense communications and even some AI‑driven sensing applications, creating a diversified revenue base that is still tied to the broader space‑data boom. That is why I view Macom’s recent rally, highlighted in coverage that linked its performance to SpaceX‑related demand and to the possibility that it becomes the next hot AI trade, as more than just a speculative spike. It reflects a growing recognition that the company’s niche products could become foundational to the infrastructure that moves data between orbit and the ground, much as STM has already demonstrated in its own corner of the SpaceX ecosystem.
What I am watching next in this “SpaceX supplier” trade
For investors considering Macom as a stealth way to ride SpaceX’s ascent, I think the key is to focus on evidence that its products are becoming embedded in long‑lived programs rather than one‑off projects. That means watching for design‑win announcements in satellite ground equipment, follow‑on orders tied to Starlink capacity expansions and any commentary from management that quantifies exposure to space‑related customers. It also means tracking how the company balances that opportunity against other growth vectors, such as data‑center optics and defense electronics, so that the story does not hinge entirely on a single customer or platform.
I am also paying close attention to how the broader SpaceX supplier complex evolves, particularly as talk of a potential listing intensifies and as analysts refine their revenue and valuation models. If scenarios like the Swinburne bull‑case prove directionally accurate and SpaceX’s valuation does move toward the levels now being discussed, the market is likely to keep rewarding chipmakers that can show tangible leverage to that growth. Macom Technology Solutions, with its specialized RF and optical portfolio and its growing association with the space‑data build‑out, looks well positioned to remain part of that conversation, even as investors weigh the usual semiconductor risks of cyclicality, competition and capital intensity.
